Bonne lecture et bonne semaine OpenSim !

It's one of the most well-known OARs, and I guess every OpenSim user with a little more experience has come across at least one instance of it: the Universal Campus.

It was built by Michael Emory Cerquoni, an early OpenSimulator developer first known in-world as Nebadon Izumi who released his creations under the Oni Kenkon Creations brand, and who is also the builder of Wright Plaza, OSgrid's famous old freebie sim. The project was a collaboration with the now-defunct Center for Computer Games and Virtual Worlds at the University of California in Irvine, and it was designed and intended to act as an actual virtual campus.

Due to the size of the project as a whole and the main building in particular, Nebadon built the Universal Campus as a mega-region, an OpenSim hack from around 2009 that made it possible to stretch a build across multiple standard regions, in this case two by two. So the Universal Campus is not one OAR, it's four, one for each region.

The first publicly available version of the Universal Campus was released in 2011, so as futuristic as it looks, it is already roughly 13 years old.

The main building shown here is outright gargantuan. It is still one of the biggest buildings around the Hypergrid. At a length from north to south of over 200 metres, it actually had to be built across a region border. Today, a decade after the introduction of varsims, this is no longer a problem.

Although it's possible to walk from everywhere on the island to everywhere else, a network of custom-made teleporters with ten destinations reduces travel time greatly. One destination is right in front of the main building, and two more are inside, the only two in-door destinations, such is the immense size of the building.

Image description

The picture in this post is a digital rendering from inside a 3-D virtual world based on OpenSimulator, generated in a regular client for this kind of virtual worlds, also known as a viewer, using shaders and generated shadows, but without ray-tracing. It shows the main building of the Universal Campus as mentioned in this post.

What OpenSimulator is

OpenSimulator, OpenSim in short, is a free, open-source, cross-platform server-side re-implementation of the technology of Second Life. The latter is a commercial 3-D virtual world created by Philip Rosedale, also known as Philip Linden, of Linden Lab and launched in 2003. It is a so-called "pancake" virtual world which is accessed through desktop or laptop computers using standard 2-D screens rather than virtual reality headsets. Second Life had its heyday in 2007 and 2008. It is often believed to have shut down in late 2008 or early 2009 when the constant stream of news about it in mainstream media broke away, but in fact, it celebrated its 20th birthday in 2023, and it is still evolving.

OpenSimulator was first published in January, 2007. It was made possible when, in 2006, Linden Lab open-sourced the official Second Life viewer, which is how client applications for Second Life and OpenSim are called, thus laying its viewer API open. This led to the development of third-party viewers. After the development of third-party viewers had started, OpenSim was developed against them and the Second Life viewer API. It does not have its own official viewer, but most of the popular third-party Second Life viewers are compatible with OpenSim as well.

Unlike Second Life, OpenSim is not one monolithic, centralised world. It is rather a server application for worlds or "grids" like Second Life which anyone could run on either rented Web space or at home, given a sufficiently powerful computer and a sufficiently fast and reliable land-line Internet connection. This makes OpenSim as decentralised as the Fediverse. The introduction of the Hypergrid in 2008 made it possible for avatars registered on one OpenSim grid to travel to most other OpenSim grids.

What grids, regions and sims are

Second Life and the OpenSim-based worlds are called "grids" because they are flat worlds divided into square areas of 256 by 256 metres each which is roughly 280 by 280 yards. These areas are called "regions". Regions can be empty, in which case they're shown as ocean, but they can't be entered. In order for any actual content to exist in a region and for avatars to be able to enter regions, a simulator, sim in short, has to run in a region.

In Second Life, a sim is always one region. OpenSim had a hack from 2009 on that was called "mega regions". It exploited a feature in third-party Second Life viewers that was not used by Second Life itself, and that made it possible to extend a sim across multiple regions in a square arrangement. The Universal Campus itself is built as a mega region of two by two standard regions. Since this hack was buggy and limited, varregions, now known as varsims, were first developed for the OpenSim fork Aurora-Sim. Eventually, they were officially introduced into OpenSim in 2014. They theoretically allow for a sim to stretch across as many as 32 by 32 standard regions with no borders in-between.

Unlike Second Life, OpenSim also has the option to save entire sims into archives and load them from archives, so-called OARs which is short for OpenSimulator Archives. Many of these are available online. Mega regions are saved in one OAR for each region, and as the Universal Campus was designed as a mega region and pre-dates varsims, it is divided into four individual OARs. A varsim, on the other hand, can be entirely saved in and loaded from one OAR.

Where the pictures were made

Particularly, the picture was created at UniCampus, an instance of the Universal Campus in OSgrid ( owned by one of the grid admins. Launched in July, 2007, OSgrid was the first public OpenSim grid and intended as a testbed for OpenSim's development. Next to Wolf Territories Grid from 2021 (,, it is one of the two biggest OpenSim grids; each one of these two grids has more landmass than Second Life.

OSgrid also adopted the early OpenSimulator slogan "The Open Source Metaverse" immediately after its launch. It still uses that slogan, and the term "metaverse" has been commonly used by the OpenSimulator community ever since.

Camera position and general setting

The picture was taken from a point of view higher than the eyes of an avatar, ca. three metres or ten feet above the ground. The position of the camera is near the inner edge of a wide path that describes an eccentric path of three quarters of a circle around the likewise circular main landing zone as well as just a bit south of the southern edge of a wide, straight path that least eastward fromo the main landing zone. The direction of view is almost northward and slightly to the west. Also, the camera is tilted upward by a few degrees due to its low position and the height of the building.

All dimensions in this description are estimated.

Main building, southern end and main entrance

The main building of the Universal Campus is the centre-piece of the image. It is a gigantic building that towers high above all surrounding trees, although it is not actually a tower, nor does it have one. It is rather a lengthy building that stretches from north to south. In the image, the middle of its front is at one third of the width of the image from the left-hand edge, reaching to the left as far as one sixth of the width of the image from the left-hand edge. The conference hall at the far end is at one third of the width of the image from the right-hand edge with parts of the building almost reaching the edge. Its supporting structure mostly shows textures with highlights included which suggest that it was made of stainless steel. Otherwise, glass with a horizontal gradient between lighter grey and darker grey on the outside and a plain darker grey tint on the inside is the most commonly used material. The building does not have any exterior walls.

The southern entrance, the main entrance to the building with the main landing area right outside the doors, is surrounded and marked by a tall geometrical structure which is rather complex in spite of only having straight edges. It resembles a spaceship from an early video game as roughly as it resembles the letter A or an upside-down V. It is almost perfectly symmetrical around both vertical planes. Its medium grey surfaces are untextured otherwise and don't mimic any particular material.

On each far side is a vertical "column" with a footprint with the shape of a trapeze, very roughly four metres or thirteen feet wide and four metres or thirteen feet thick. The short side of the trapeze, measuring only a bit over three and a half metres or twelve feet, is on the outside. These columns rise up some nine metres or 30 feet on the inside. The top slopes downward towards the outsides, so the columns are less than eight or about a half metres or 27 feet high on the outside.

The centre and top piece of the structure, right above the doors and roughly seven and a half metres or 25 feet above the ground, is roughly ten metres or 33 feet tall and roughly four and a half metres or fifteen feet wide. It has a rectangular cross-section when looked at from inside the building or from the main landing area, but a heptagonal cross-section when looked at from the sides. Its seven visible faces are all rectangular. At the bottom, it is roughly five metres or roughly sixteen and a half feet thick with only one surface. The top is roughly five metres or roughly sixteen and a half feet thick, too, but with a pair of surfaces of the same size at an angle of under five degrees, forming a slight ridge at the top.

The inner and outer sides of this centre-piece are each made up from an upper surface which is a square and sloped outward from the top and a lower surface which is a rectangle and sloped outward from the bottom. They meet at an angle of roughly 20 degrees.

On each side, two irregularly-shaped structures of seven surfaces each connect the seven edges of the sides of the centre piece with the four edges of the inner sides of the columns. Six of these surfaces are more or less slightly twisted because they connect edges at different angles with each other. The only planar surface is the one that connects the bottom edges which are all horizontal.

Two pairs of double glass doors make up the actual main entrance. Each door blade is about two and a half metres or eight feet wide and about five and a half metres or eighteen feet high. The glass has the same horizontal gradient texture both on the inside and on the outside so that all door blades can be identical. The only difference between the door blades is whether the door script opens them clockwise or counter-clockwise. The texture is arranged in such a way that there are narrow lighter areas along both vertical edges when the hinge is on the left, and there is a wide lighter area on the lock side and a narrow lighter area on the hinge side when the hinge is on the right. The narrow sides of the door blades are opaque when looked at from the outside but, due to OpenSim's limitations, not when looked at from the inside. The doors open inward by 90 degrees, and they do so when they're clicked, or when an avatar approaches them. They can be closed manually by clicking them again, otherwise they close automatically after ten seconds.

Each door blade has one simple door handle on the inside and the outside tinted the same generic grey as the large structure surrounding the doors. The handles are only a few centimetres wide. The grips have a square cross-section. Above and below, there are thicker parts which connect the grips to the doors while being flush with them on the sides and facing away from the door blades. Altogether, each handle is half a metre or one and five eighths feet long. The top of each handle is about one and three quarters metres or five and three quarters inches above the ground.

Between the two door pairs and on their sides, there are altogether three columns with a rectangular footprint of roughly 90 centimetres or three feet width by 30 centimetres or one foot thickness, each roughly seven and a quarter metres or 24 feet tall. Above each pair of doors, they are connected with a horizontal beam that fits between the top surfaces of the columns and the top edges of the doors while being half as thick as the columns.

The spaces between the large structure around the entrance, the columns and the horizontal bars are filled with glass panes.

The whole door ensemble does not sit exactly at half the thickness of the large structure. It is shifted outward by about half a metre or one and five eighth feet.

A structure shaped like an almost flat pyramid, but with a flattened top, is mounted upside-down against the bottom surface of the centre of the large structure around the main entrance. The glass pane above the doors passes right through its middle. A square light is installed on the flattened top which is actually the bottom now, illuminating the entrance area when it is dark. Otherwise, this flat structure has the usual brushed stainless steel texture which appears rather dark here.

On each side of the entrance area, a cylindrical column with a diametre of roughly four metres or thirteen feet rises some 20 metres or 66 feet upward. Each column is slightly tilted inward along the longitudinal axis of the building and outward to the sides. On each side, farther outside, there is another, even taller column, easily over 30 metres or 100 feet tall. These columns are tilted along the longitudinal axis of the building at the same angle, but outward to the sides at a smaller angle. They make up the southern corners of the main building. All four columns are textured to resemble brushed stainless steel.

A semi-cylindrical structure connects the complex main entrance structure through the inner columns with the outer columns on the ground. Its diametre is roughly 2.40 metres or eight feet. It uses the usual brushed stainless steel texture, but the brushing direction is radial, and the texture is stretched along the axis of the cylinder so much that its nature is anything but obvious.

Between the columns and the main entrance structure, there are three more glass panes. The panes between the inner and outer columns are mounted halfway into the building whereas the one around the main entrance structure is almost all the way inside the building. Three horizontal stainless steel rods of about 30 centimetres or one foot lead through each pane. They are roughly evenly spaced, but closer to the upper and lower edges of the glass panes than to each other. The rods that pass through the panes between the columns grow to a diametre of roughly 45 centimetres or one and a half feet towards their ends before ending in short cylinders with diametres of about 1.80 metres or six feet.

On top of the inner columns and partly intersecting with the outer columns, a massive, upright, flat structure with stainless steel textures serves as the southern end of the roof. It has to be about 50 metres or 160 feet wide, about 15 metres or 50 feet tall and about 3.60 metres or 12 feet thick. The front and rear surfaces are slightly countersunk with margins of slightly varying thickness all around except for the bottom. The top edge has a fairly short horizontal section of ten metres or 33 feet in the middle from which it curves downward in sections of ellipses. The bottom edge is almost horizontal and leads to corners from which short 45-degree slopes lead upward. The slopes from the bottom and the ellipses from the top meet in rounded corners. Unlike the columns below, this roof end is mounted vertically.

Main building, Universal Campus logo

The roof end also carries the logo of the Universal Campus, sitting at half the height of the outer countersunk area of the roof end and ever so slightly to the left of its middle. Its base is a circular, conical structure with a diametre of ten metres or 33 feet, the sloped edge being black. The actual logo is part of the texture on the front surface of the cone. It has a diametre of about seven metres or 23 feet.

The inner 80% of its diametre are filled with a gradient from medium dark grey at the top to medium light grey at the bottom. Three shaded three-dimensional primitive shapes are displayed in this area, a cube with one corner each pointed to the top and the bottom at the top, a sphere in the bottom left, a tetrahedron in the bottom right. At the bottom of this area, "Patefacio radix" is written in medium dark grey letters, in a wide sans-serif typeface and in what is likely to be small caps. It is Latin for "open source". Below, the Roman number MMXI, 2011, marks the year of the first public release of the Universal Campus.

A thin dark grey circle separates this area from the outer 20% which are light grey. Re-using the same typeface as in the inner part, and in dark grey with blue shading, "Universal" is written at the top and "Campus" at the bottom, both capitalised with otherwise small caps and following the circular shape of the logo.

29 identical black circular spots, very roughly evenly spaced, protrude from underneath the logo all around it by a bit more than their own diametre. They separate the logo from the surrounding white area which, in turn, is surrounded by the aforementioned black conical slope.

The Universal Campus logo is illuminated from below. The light source sits in a slot in a cylinder on top of the main entrance structure, about two metres or six and a half feet long and a diametre of about 30 centimetres or one foot. This cylinder has spherical end pieces, and the whole arrangement has a simple, glossy, medium grey surface.

Main building, side

Each side of the building, all the way to the conference hall at the northern end, is tilted outward at the same angle as the corner columns around the front and much simpler in design. Starting north of the side entrances right behind the front, a semi-cylindrical structure on the ground, similar to those at the front, extends northward towards the conference hall, only interrupted by another set of side entrances shortly before the conference hall. Farther up, there is another cylindrical structure of the same diametre and with the same texture on each side, but with a cutout on the upper inner side of a bit over 90 degrees to help carry the upper floor on the right, actually semi-cylindrical on the left and stretching all the way between the columns on both sides. Even farther up, right below the roof, another cylindrical structure is installed, but cut out on the inside by 60 degrees upward and 75 degrees downward.

Eight cylindrical beams with a diametre of roughly 90 centimetres or three feet and the usual stainless steel texture serve as the near-vertical supports. Nearly evenly spaced, except for the first being closer to the second, and running from the bottom to the top, they divide each side into eight full-sized sections and one small section right in front of the conference hall.

As mentioned above, the building has four sets of side entrances. One on each side is right behind the front behind the colour and the first support beam, one on each side is just south of the conference hall between the seventh and eighth support beams. The doors are identical to the ones that make up the main entrance, but each side entrance has three pairs of doors instead of two.

Between the three double doors, there is a filler column with a rectangular vertical cross-section, a width of about 45 centimetres or one and a half feet and a thickness at ground level that is slightly less than the width. While the inside surface is vertical, the outside surface is sloped in parallel to the outward tilt of the side of the building. Similar but wider columns are installed on the sides of the doors, being the closest that the building has to outer walls. Another structure with a rhomboid north-south cross-section sits on top of each set of four pillars, connecting them and carrying a glass pane on top. Its inside surface is sloped outside, its outside surface has a stronger slope than the outer side of the building. Also, its texture is lighter than that of the pillars.

Everything else between the vertical and horizontal structures on the sides of the building is filled with glass panes, all with a light vertical streak down their centres, blurred by the gradients on its sides.

Main building, roof

On the visible right-hand side of the building, right above the positions of the first seven of the eight support beams, curved brackets reach down from the roof, holding the upper horizontal cylindrical beam from the outside. They appear to be dark grey, but they actually have the usual brushed stainless steel texture. These brackets are installed on both sides across the outer parts of the roof, and slightly larger versions span across the centre of the roof as can be seen from below through the windows of the building.

A little bit of roof is visible underneath these brackets. The roof has four identical sections from its end to the conference hall. All are mostly planar with a rounded outer side. From above, they have the most elaborate surface of the whole building. It is almost black. A bump map or a normal map divides it into slightly embossed and slightly less rough rectangles, slightly countersunk and slightly rougher rectangles and the another bit smoother lines in-between. The rectangles are of varying size. They have an aspect ratio of four to five along the building's longitudinal axis by three to four along its transversal or vertical axis. In addition, the texture on these roof segments is glossy, giving it a plastics-like appearance. From below, however, it is smooth and transparent with the same tint of grey as the glass panes.

Between the inner and outer sections of this kind on each side, there is one long textured strip, on top of which rest the larger brackets across the centre of the roof. Its texture is slightly glossy, but hard to identify as resembling something: It consists of stretched rectangular fields of medium grey, arranged transversally, with very thin dark grey outlines, surrounded and interrupted by narrow areas of medium light grey which are emphasised by bump-mapping or normal-mapping which makes them appear embossed as well as specular-mapping which makes them appear glossier than the rest. Within these fields, but at some distance from its outlines, there are more nested rectangles, from outermost to innermost: medium dark grey, dark grey, medium dark grey, medium grey and slightly bumpy, medium light grey and bumpier as well as appearing to be slightly countersunk, light grey and appearing to be even more countersunk. This pattern repeats over a hundred times over the length of the southern part of the building. It is on the bottom face of these two strips as well, but not on its narrow sides.

The very middle of the roof is simply one long glass pane. It is separated from the dark sections to its side by what seems to try to resemble rectangular aluminium profiles with the long sides oriented vertically. On each side, at a height right above the glass pane, there is a stripe that glows white in the dark while not actually being a light source; this is another OpenSim limitation.

Main building, domed conference hall

Beyond these parts of the building, a large geodesic dome rises up, below which is the conference hall. It is assembled from triangular glass panes in seven rows, four of which the image shows from outside, and untextured light grey cylindrical rods. The glass panes have the same tint or texture on both sides. The ones in the two bottom rows have the usual grey tint. The two rows above have the same lighter texture which most of the other panes on the building have on the outside. Unusually, this geodesic dome has no points at which five triangular panes meet. On all points which aren't on the bottom edge, six panes meet except for the very top where only four panes meet.

The dome is surrounded by a huge, disc-like object of varying thickness, but very thin on the eastern side which is revealed in the image, that is well over a hundred metres or 330 feet in diametre. It is bascially an eccentrical cone with a circular outer shape and a way off-centre hole towards it slightly slopes down. The geodesic dome mostly rests on the edge of the hole which means that the outer edge of the disc is shifted way to the east. There is also a cutout towards the south all the way to the circular hole, uncovering the roof of the southern part of the building. The western edge of the cutout deviates from being parallel to the longitudinal axis of the building by a few degrees to the right. The eastern edge of the cutout points at the centre of the circular hole.

Along the outer edge, the top surface of the disc is tapered over a distance of about seven and a half metres or 25 feet so that the outer edge is almost razor-sharp. For unknown reasons, the western edge of the cutout shows a similar sharpness by being tapered at the bottom.

The upper and lower surfaces of the disc shows variations of the usual brushed stainless steel texture. The cutout faces, however, show a dark grey texture with four darker grey grooves upon zooming in.

Right below, there is a second, similar asymmetrical cone, but smaller in diametre, even thinner and with a bigger slope. Its outer edge touches the first disc from below. Being dark coffee brown, it is the only outward part of the building that is not a shade of grey. Also, while it is half-transparent like tinted glass from above, all other surfaces are opaque and glossy, so it's possible to look through it from above, but not from below.

The inner edge of the brown cone connects to a ring around the conference hall at about roof height on the outside or the top. The ring describes about three quarters of a circle with the opening oriented towards the southern parts of the building. It has a slightly darker tint on its brushed stainless steel texture.

The ring also serves as the upper connection between the seven cylindrical pillars that surround the conference hall, four of which are hidden behind the building itself in the image. They have a diametre of about six metres or 20 feet, and they vary in length by a few metres. They all stand on the ground, and they are sloped outward from the conference hall, partly intersecting with the two cones above.

Main building, interior

Since the outer surfaces of the building are mostly glass, more can be seen inside the building than just the underside of the roof. Horizontal support cables are mounted between the textured roof strips and underneath each of the seven central roof brackets. They are similar to those through the side window-panes in the front, but longer and thinner. From all of these but the southernmost one, two darker, thinner and shorter support cables lead downward. Another pair is mounted farther south against the textured roof strip on its side. These fourteen vertical cables support the upper floor on its inner sides.

The upper floor is roughly U-shaped with the opening towards the south and the main entrance. It also serves as the ceiling for the ten seminar rooms on the ground floor, five on each side, above each of which it extends inward with a semi-elliptic shape. Its bottom side, the ceiling, is light grey. It has a bump map or a normal map which not only roughens it up but also divides it into octogonal pads with rectangular spaces in-between. The vertical surfaces towards the aisle have a texture that simulates small, square, dark grey panels in four rows held in place with one rivet in each corner. The seams between the panels are black. On some surfaces, the textures have obviously been stretched horizontally, making the panels rectangular, the rivet heads elliptical and the vertical seams wider than the horizontal seams. The upper side with its bluish-grey patterned carpet texture cannot be seen in the image.

The entire inner edge of the upper floor is protected by a railing. It consists of one mostly light grey rail with a rectangular cross-section on the floor, an identical rail that is a bit over 1.20m or four feet high above the floor and a number of small, slightly darker grey vertical beams with a square cross-section which connect them. The whole railing lacks texture and gloss.

Of the seminar rooms on the right, only the separation walls can be seen through the panes on the right of the building. These have mostly tan textures but with coarse and blurry stripes of various greys at the top and bottom.

Through the right-hand pane in the front, two seminar rooms on the left are visible, the rooms A7 and, north or to the right of it, A8. The seminar rooms A7 through A9, as well as A2 through A4 on the right, have a variety of untinted glass doors each: one in the northern corner towards the central aisle, another one in the southern corner, and one in each of these two corners that leads to the neighbouring seminar room. Apart from the lack of tint or texture, the glass doors are identical to the entrance doors.

The aisle-side wall of each seminar room can be described as convex although it is not rounded. It rather consists of four segments separated by narrow vertical columns with square footprints. They are connected by a number of horizontal rods with a rectangular cross-section. One is always right under the ceiling. Three more are roughly at 65%, 50% and 33% height above the ground. For the outermost segments, this is the height of the glass doors, so underneath the rod at 33% height above the ground, they have another vertical rod to separate the doorway from a narrower piece of wall. At some 12 or 13% height above the ground, there is another rod, and the last one is on the ground, in both cases except where there's a doorway.

The space between the latter two horizontal rods is filled with a wooden panel, showing the same reddish wood grain as all wooden-textured furniture in the building and on the sim. The other spaces have untinted glass panes in them. To illustrate the dimensions: The wooden panels are about 1.80 metres or six feet high, so for realistically-sized avatars, the only way to look into or out of the seminar rooms is through the doors.

On the vertical rod next to each aisle door, a sign with the room number is installed. The sign itself is simple, flat and rectangular. It is entirely black except for the white room number written on it in a regular Helvetica sans-serif typeface. It is attached through a glossy white cuboid that serves as a very simple mounting bracket.

Furthermore, there is an easel with a blank whiteboard standing next to each aisle door. It is a simple construction from cuboids, cylinders, a tetrahedron at the top and small spheres for feet and joints. Apart from the whiteboard which is mostly white and untextured except for the plywood texture on the back, the whole thing shows a brushed stainless steel texture with some gloss added.

Inside each seminar room, visible through the window-pane behind the easels, there is a whiteboard which is a much more elaborate construction. Each room has two of these. There is also a dark grey HDTV screen attached to the middle one of the three columns with a wall-mount swivel arm. A bit of furniture is barely visible through the closed glass door: Each room has seven quite long tables with elliptical ends, one long light grey foot on two legs with a wooden plank between them and a dark grey surface surrounded by wood grain. Six of these tables are for seminar participants with two chairs each. These chairs consist of two wooden parts in the shape of a stretched U with rounded sides and dark grey padding, two small metal rods connecting them and four conical metal legs. The seventh table is for the teacher whose chair is identical to those for the participants, only that it has an extra headrest in the same style as the rest of the chair plus a pair of elliptical armrests.

Main building, further interior objects

The large object that appears to be standing in front of seminar room A7 is a teleporter that was specifically designed for the Universal Campus due to its size. It is actually standing in the middle of the aisle, the control panel turned southward towards the main entrance. It is mainly a rectangular console on a massive angled stand. The frame around the control panel included, the console itself is about one and a half metres or five feet high and about three metres or ten feet wide. Above the control panel, there are two tiny spherical light sources on small trapezoid arms. They actually emit light to illuminate the control panel of the teleporter.

The control panel is labelled in a typeface not entirely dissimilar from Futura. On its left, there is a top-down view of the entire Universal Campus with the north oriented to the left. It shows the various buildings and other places. Ten circular markers are placed on the map, all with a glossy grey frame and a black number from one to ten. All markers but one are yellow; one is always glow-in-the-dark green. In this case, it is marker number 6 to the right of a rectangular building with a circular extension in its bottom corner. Below the aerial view, there is another, slightly bigger yellow circular marker, but with a red frame surrounded by a glowing red aura while not glowing itself. It has the number 2. Next to it is a label with an arrow-like point to the left that reads, black on white, "This is currrent (sic) location". It is up to the user, however, to find the marker with the same number on the map.

On the right of the control panel, there is a touchable list of destinations with their numbers in markers of the same size as the glowing red one in the bottom left, but with the usual shiny grey frame. The labels with the names of the destinations are identical in style with the current location marker:

1: Main Landing Zone
2: Main Building Lobby
3: Main Conference Hall
4: Recreation and Conference Center
5: Observation Deck and Sea Lab
6: Science Lab and Conference Room
7: Campfire and Beach Zone
8: The Light House
9: Engineering Conference Center
10: Helicopter Landing Pad

Just like on the map, destination number 6 is the only one with a glow-in-the-dark green marker and a glow-in-the-dark green label background. It is the currently chosen teleport destination. Upon clicking another one, it would be marked green, as would be its marker on the map. Below the list, there is another white label, but with an upward arrow point on its left-hand end that points to the column of numbered markers. It reads, "click to select location then right click and teleport!" This means that if the user were to right-click the panel, thus opening a pop-up menu, and then choose the option "Teleport", the avatar would instantly be relocated to whichever location is selected on the teleporter. To the right of this label, there are two small red triangles with glowing auras pointing upward; they appear to be non-functional.

The background of the control panel is glossy medium grey. The rest of the structure is glossy with a gunmetal-like dark grey texture.

There are also quite a few potted plants inside the building. On the sides of the teleport panel, there are two identical açaí palms in square terracotta pots with wide rims. Like the other potted plants, these mostly dark green plants with long pointy leaves are kept at an indoor-compatible size, namely about three and a half metres or eleven and a half feet tall. Also, like the other potted plants, they are made of only four flat and surfaces with partially transparent pictures of the plant on them, arranged in angles of 45 degrees to one another.

Through the main entrance, a slightly taller Jacaranda tree with dark lilac flowers can be seen. It is planted in a bulgy terracotta pot with a smaller rim than the square ones which is supposed to be round. In order to reduce the impact on graphics performance, however, the pot is actually hexagonal. There is also one of the two angled flights of wooden stairs leading to the upper floor and, outside the building again, a small but wide maple tree with brown autumn leaves. A look through the side entrance to the right shows an even slightly taller Bougainvillea with purple flowers. Above these doors, the underside of the upper half of the other flight of stairs is shown. The steps are not covered from below, and the spaces between them are open.

Some of the unusual dividers on the upper floor can be seen through the windows, too. The main element is a half-arch of a bit over 90 degrees from the floor to the tilted structures on the side of the building. Its core is a thin, roughly 1.80 metres or six feet wide circle segment with an inner radius of about four and a half metres or fifteen feet and a dark grey texture which resembles some kind of rock. It is lined on both the inside and the outside with arches with a brushed stainless steel texture. The inner arch is about 45 centimetres or one and a half feet wide, the outer arch is slightly narrower, and both are significantly thicker than the core arch. From both ends of the arch, narrow brushed stainless steel bars extend to the centre of the arch where they meet. They are thinner than the stainless steel arches, but thicker than the core arch. Finally, the area between the two bars and the inner arch is filled with a grey tinted glass pane.

On each side of the upper floor, there are six such dividers. The southernmost ones are installed right above and north of the stairs and attached directly to the vertical structures on the sides. Between the other ten and the side structures, there are horizontal extensions in much the same style. The arches themselves are extended to the sides by two rhomboids in the same style, a longer one of some four and a half metres or fifteen feet with four cylindrical connectors of roughly 60 centimetres or two feet of diametre on its corners underneath which avatars can pass and a shorter one of some three metres or ten feet which connects to the vertical structures. The latter one also has a third stainless-steel-framed rhomboid all the way down to the floor underneath itself which is filled with a grey tinted glass pane.

Avatars in OpenSim and the avatar vendor rooms

On the eastern side of the building, barely visible through the large glass surfaces, there is an area that offers complete classic avatars as well as classic avatar accessories.

Unlike in most other 3-D virtual worlds, avatars in OpenSim-based worlds, just like Second Life, are not monolithic. They are highly modular, they are highly configurable, and they have evolved over the years. The most basic classic avatar consists of five components that always have to be there. The only one that cannot be replaced is the system body which is automatically generated by the viewer application. OpenSim has the same system body as Second Life. The four components that can be replaced but never removed are the shape which greatly defines the look of the avatar with 88 parametres, the skin which is a set of three textures for the head and which can be tinted with parametres, the upper body and the lower body, the hair which defines the shape and length of the classic hairdo growing out of the head as well as its texture, and the eyes which are basically only a texture again.

Classic clothes are also referred to as layer clothes because they are just that, layers of textures painted onto the system body. Their order is defined by nine categories, in each of which a classic avatar can only wear one kind of clothing. A few of these have an influence on the shape of the avatar: The shirt and the jacket can widen the arms to simulate sleeves. Likewise, the pants can widen the legs downward to simulate pants legs and even bell-bottoms. And the shoes can both raise the avatar in general and grow a sort of spike out of the heel, lift the whole avatar except for the toe area because the system body does not actually have toes and thus generate high heels. A separate layer is for skirts; it textures a part of the system body which is usually fully transparent and thus invisible. In 2011, four tattoo layers were added between the skin and the two underwear layers.

It is also possible to attach objects to an avatar at 30 different points, and it has been for as long as OpenSim was around. This was quickly used not only for things carried by the avatar, jewellery or other accessories, but also for more realistic hair, for better-looking shoes in comparison with the painted-on classic shoes, for various ways of having new shapes of skirts, for collars, for pants legs et cetera.

Originally, these attachments were made from primitive objects or "prims" in short: basic shapes like cubes, spheres, cones and the like which can be generated and manipulated a lot in-world without needing external software except for making textures. Since building complex objects from them is somewhere between highly complicated and impossible, it was made possible to import sculptmaps as exported from 3-D software like Blender and use them to create more complex prims. All kinds of prims can be made flexible with a little bit of physics which is used for hair and skirts as well as for flags, but the physics don't have collision detection.

The next step was the introduction of mesh. Mesh allows the user to directly import 3-D files in the Collada format, texture mapping included, without having to resort to sculptmaps. Mesh came to Second Life in 2011, as did experimental mesh support in OpenSim. The first stable release of OpenSim with mesh support came out in 2014. On avatars, mesh was originally used for hair, shoes, jewellery and other accessories. It really started a revolution with the introduction of rigged mesh which automatically latches itself to multiple points on the avatar. This made it possible not only to create clothes that move with the avatar's movement, but even to create all-new, better-looking bodies and heads. Nowadays, most avatars consist entirely of mesh.

The newest technological advancement for avatars was Bakes-on-Mesh which came up from 2019 on. This allows classic layer textures to be put onto worn mesh, especially mesh bodies, and in greater numbers than on the system body. The main purpose was to get away from skin appliers, scripted devices that have to be put on and used to put a different skin onto the mesh body. Also, the remaining onion layers around mesh bodies that were necessary for tattoos, but made mesh bodies unnecessarily complex, had become obsolete because Bakes-on-Mesh allows for wearing classic layer tattoos on mesh bodies. But it also makes wearing layer clothes possible again which can make sense in the case of skin-tight clothes.

The latest version of the Universal Campus from 2012 already uses mesh for a few things, mostly rocks. The main building itself and everything else shown in this image is still put together from prims and sculpties.

As for the contents in the avatar vendor area, none of it is newer than from 2011. Everything is still from times before mesh. The complete avatars come with layer clothes, but no attachments. They, like the skins and hair attachments, were created by Ina Centaur under the OS Avatars label around the same time as the Universal Campus. Many of the other items, the majority of which were made by Nebadon Izumi himself, are even older. All of them are offered under free licenses, however. In order to announce their availability, three of the divider extensions have signs mounted above them which can be made out in the picture. They are oval, black with a stainless steel frame, and they have the glowing, but not light-emitting white word "AVATARS" written on them in all-caps and in a typeface which looks to me like a regular Linux Libertine. The writing even uses proper kerning between the "A"s, the "V" and the "T".

In the first two of the three avatar vendor rooms, the rear sides of four stainless steel vendors each, lined up on the outer side of the room along the longitudinal axis of the building, and especially the signs above them on thin cylindrical stands can be made out, the only ones that aren't hidden behind something. The first four vendors offer one female skin each, the other four offer one male skin each. The displays on these eight vendors are oriented away from the camera.

Main building, upper floor, western side

The first two rooms on the western side of the building are conference areas, the other two are empty. Not much of them is visible except for three of the dividers, a semi-circular couch with a wooden frame and ten seats, a small banana tree in a hexagonal white concrete pot, another whiteboard and two HDTV screens in stainless steel casings on floor stands. One of them shows the monochrome test pattern which is actually on all of them, and which includes several screen-testing elements as well as a large medium grey circle in the middle with a white, a black and a thinner medium grey border around it and the digit 2 in black and in a heavy, condensed sans-serif typeface and a white square grid on medium grey ground with the capital letter "C" in two combined fields at the bottom.

The main landing area outside the main entrance

In front of the main entrance, there is the main landing area of the sim, a part of which is still within the image towards its bottom left. It is circular in shape with a diametre of about 40 metres or 130 feet. The centre of this circle is about 35 metres or 115 feet south from the main entrance of the main building. It shows the same light grey texture reminiscent of concrete that is used on most paths on the island. The texture is not shrunk to a realistic size, so it appears coarse and having a low resolution.

The outer edges of nearly all concrete surfaces on the island are lined with low walls of varying height and width. They all have the same concrete texture, but at a smaller scale and without the light grey tint so it appears almost white. The main landing area actually has two rows of walls around it. The inner walls are a bit over 1.20 metres or four feet high and about 1.50 metres or five feet wide. The outer walls at a distance of roughly three metres or ten feet are about 1.65 metres or five and a half feet high and about 1.80 metres or six feet wide.

At the ends, the gaps are closed with walls a bit lower than the inner walls and roughly 90 centimetres or three feet wide. The spaces between the walls are filled with dirt. They form planters with identical shrubs in them; the short planters in the northwest and the northeast visible in the image have five plants each. These shrubs are not named in-world. They appear to be of tropical origin, and they have flowers with petals that are mostly white, yellow towards the centre and magenta along their edges. Like all trees on this sim, the shrubs are made of simple, textured sculpty prims for the trunks and branches, and the twigs, leaves and flowers are semi-transparent textures on intersecting two-dimensional surfaces, a popular way to make plants in Second Life and OpenSim before the arrival of mesh. The textures used for all plants on this sim are photo-realistic as far as the maximum possible or feasible texture resolution allows.

On the left-hand edge of the image, in front of the northwestern planter, there is another teleporter which is almost identical to the one that can be seen inside the building. There are two differences, however: Its current location is number 1, and the selected location in the image is number 4. Another one of the unidentified shrubs appears between the teleporter and the left-hand edge of the image, partly hidden behind the teleporter.

Another single-target teleporter is standing on its right. It is a custom addition to this particular instance of the Universal Campus. It was built by Neovo Geesink, formerly of Metropolis Metaversum fame and now involved in OSgrid, in his trademark style. This style includes a particular brushed stainless steel texture which, unlike those used by Nebadon Izumi, emulates the surface having been brushed circularly. The stand under the panel is a simple cone, flattened to an extremely elliptical footprint. The panel is as high as that of the original teleporter, but only slightly wider as it is high. The frame around the image in the centre is slightly narrower than that on the original teleporter.

The image itself shows an aerial view of its single hard-coded target, a sim named TeleHub, built and operated by Neovo. It is nothing more than a single region, a square of 256 by 256 metres or 280 by 280 yards, surrounded by blue ocean and a wall made of beige bricks which is about ten metres or 33 feet high. The ground is tan and divided into four triangular areas by two diagonal lines. In each area, there are 141 single-target teleporters similar to this one, but with a higher panel, in rows of eleven. A few show previews of their targets, but most are unused with black screens. In the very centre, there is a small circular platform on which avatars land after teleporting in. It has a beige top surface with a hexagonal tile pattern and a woodgrain texture on the sloped surface all around. Four arches with textures resembling rough taupe stones and black signs on them lead to one triangular area each. The position of the camera is off one of the corners and pointing diagonally downward to one of the yellow division lines.

Yet another one of the identical unidentified shrubs is behind this teleporter and shown to its right.

In the background, the low walls on the sides of a path appear between the shrub behind the teleporter to TeleHub and the main building. The path is straight and leads northward along the western side of the building.

Even farther in the background, behind the two teleporters, there is some vegetation. From left to right, it starts with an unidentified tree of about eight metres or 26 feet of height. It has reddish-brown bark, medium green leaves in pairs and what could be taken for pale yellow-ish fruit. Below it, there is a large bushel of khaki-coloured grass that stands about two and a half metres or more than eight feet high. The tree intersects with another maple tree with brown and tan leaves that is about ten metres or 33 feet tall with more massive greyish trunk and branches. Immediately to the right again and partly intersecting with the maple tree, there is an even unidentified tree, about 17 metres or 56 feet tall, with grey bark on a fairly slim trunk and a messy crown of dark, brownish-green leaves which are so small that the texture makes it impossible to tell individual leaves. This tree is partly hidden behind the building already. It has another two bushels of the same tall grass underneath it which, due to the point of view, only seem to stand immediately to the right of the trunk.

Behind this vegetation, right below the crowns of the trees, the horizon separates the sky from the sea. What little sea the image shows is medium light blue. The sky right above the horizon is very light cyan, and around half the height of the image, it gradually changes into a tone of blue similar to that of the sea. From the top left corner of the image downward and to the right, more than half of the sky is covered by a cirrus-like thin cloud with a small hole above the roof end of the main building. On the right, the cloud dissolves into smaller clouds above the geodesic dome and the surrounding thin cones.

Further additions to the Universal Campus include five easels of the same type as seen inside, but with custom writing in it. They are lined up next to each other in front of the northeastern planter, starting right next to the wide path towards the main entrance. The writing on all five easels is done in black and in an unidentified humanist sans-serif typeface which appears condensed due to the texture having been stretched vertically, thus losing its original aspect ratio. Only the writing on the first of the five is visible from the camera's point of view, though. It reads in three lines, "To download a free copy of the Universal Campus Var Region." This is followed by a blank line and one more line that reads, "Click here for notecard". Upon clicking the easel, it gives the avatar a notecard with an Amazon cloud storage URL following an explanation that it contains the Universal Campus as a varregion archive and followed by a full copy of the Creative Commons Attribution-ShareAlike 3.0 Unported license.

Around the main landing area and the main building

Due to limitations in construction with prims, the ground of the main landing area is slightly higher than that of the three paths which lead away from it. The widest one of these paths is about one third of the diametre of the landing area in average width that leads to the main entrance. It is trapezoid in shape, and its sides line up with the centre of the main landing area. Two more trapezoid paths, also widening with the distance from the centre of the main landing area but only half as wide as the first one, lead westward and eastward from an imaginary point a little north from the centre of the main landing area. The western one is not visible in the image except for on the aerial view on the teleporter. The eastern one makes up most of the foreground along the bottom edge of the image.

On the outer corner of the northeastern planter on the eastward path, there is a lamp post standing on an almost white, cylindrical concrete block of about 1.80 metres or six feet of both height and diametre. From the camera perspective, it is in front of the main building and near the westernmost front column. It appears to be almost parallel with the column, but the lamp post is vertical while the column is tilted roughly northwestward.

The lamp post itself is about seven and a half metres or 25 feet high and very slightly conical with an elaborately-shaped round foot. At the top, it describes a sharp 90-degree angle towards the path, rounded on the outside, forming a corner on the inside. It then extends conically towards the path by another roughly 1.50 metres or five feet before ending in a small sphere. The bottom of the sphere is flattened, and the actual light source is installed on this flat surface. It is round, glowing and emitting slightly yellowish light. The rest of the lamp post is light grey or white and highly glossy.

The walls lining the paths to the sides of the main landing area rise no more than about 30 centimetres or one foot above the paths themselves while being twice as wide.

In the bottom right corner of the image, the path to the east intersects with a circular path around the main landing area that begins and ends near the southern side entrances of the main building. Its centre is some ten metres or 33 feet north of that of the main landing area, and its outer diametre is about 100 metres or 330 feet. Due to the aforementioned limitations, it is a little bit higher than the trapezoid spoke path at the bottom. Its walls rise about 60 centimetres or two feet above itself and about 80 centimetres or a little less than three feet above the path to the east, and they are about 2.40 metres or eight feet wide.

Between the main building, the path to the main building, the planter northeast of the main landing area, the path in the very foreground and the circular path on the right, a large patch of sim ground is still unused. It shows a green texture with some slightly darker or minimally more yellow-ish areas. The texture has a fairly low resolution. It is coarse and blurry, and at the same time, even this patch of ground reveals the repeating texture tiles. The ground itself is rather bumpy as though it has been manually treated to be like this. All the same applies to the corresponding area to the west of the path to the main building of which fairly little of it is revealed in the image.

Right before its end near the right-hand entrance, the circular pathway first branches diagonally to the right to another path three small steps down. On both corners of this junction, there are fairly cylindrical platforms inserted into the walls. Both have a diametre of about 3.60 metres or twelve feet and a height of about 1.20 metres or four feet above the branched-off path or a bit under 90 centimetres or three feet above the circular path. The walls along the branched-off path are fairly small, only some 45 centimetres or one and a half feet high and about 60 centimetres or two feet wide.

After about 15 metres or 50 feet of length, the branched-off path continues down a set of stairs. Due to how low the camera position is, the stairs itself are hidden from the camera, but the block and guide rails along the far side of the stairs, the northwestern side, are not. The block is the same shade of grey as the surfaces of the paths. It serves as a primary guard on the sides of the stairs. It is about 90 centimetres or three feet wide. It ascends from the usual wall on the side of the path which it overlaps by the same amount on both sides, and it does so at an angle of roughly 25 degrees. It reaches its peak right above where the stairs start at a height of about two metres or six and a half feet above the path. From there, it descends at an angle of about 35 degrees which, curiously, is a little less steep than the stairs themselves.

The guide rails are dark blue flat slabs, about 30 centimetres or one foot wide and about seven and a half centimetres or three inches thick. They come in stacks of four, arranged above one another with round about one and a half times the thickness of one rail worth of space between them. They are parallel to the descending surface of the block. The lowest one has a distance to the block of circa 30 centimetres or one foot. Each set of rails is held together and in place by two shiny, textureless blocks of 120 centimetres or four feet of height and a square top surface which, however, slightly narrows downward to the large concrete block below when looked at from parallel to the rails. Upstairs, the four rails extend beyond the stairs by roughly seven and a half metres or 25 feet. Their upper ends are lined up almost exactly vertically. The whole arrangement is slightly shifted out of centre on top of the block, away from the stairs. A second, identical set of rails is installed further downstairs for no apparent reason other than looks. Such rails are actually on both sides of the stairs, but the image only shows them on one side.

Shortly before the stairs, one lamp post like the one is installed on the wall on each side of the path towards the stairs, complete with the cylindrical block underneath. In the image, the lamp post on the right with the exception of the foot and the cylindrical concrete block underneath is almost entirely obscured by two trees. One is identical to the tree with the chaotic brownish-green leaves to the left that is partly hidden behind the main building. It has another bushel of grass around where its roots were if it had any. Another much larger one is standing to its right, its trunk and most of its crown outside the image already. It is unidentified, too, but it shows some signs of being an acacia tree. Its bark is mostly greyish-brown with some rusty red patches on it. Its leaves are long, pointy and various tones of pale light to not-quite-as-pale medium green.

Immediately after the path towards the stairs branches off, the circular path leads into a straight path that runs parallel to the eastern side of the main building. The walls on its side have the same size as those on the sides of the circular path. On both of its ends, short, wide platforms lead to the side entrances of the building, connected to the path via two small steps each. These platforms do not have walls on their sides. At the far end, the straight path leads into another circular path, this time around the conference hall.

Some more vegetation is to the right of the path along the eastern side of the main building, all standing on sim ground. Right behind the unobstructed lamp post next to the path that leads downstairs, there is a fairly large unidentified tree that almost reaches the edge of the roof of the building. Its crown has rather dense foliage in a quite saturated medium green tone. The bark texture on its thin trunk and branches is mostly taupe with bits of copper brown and fairly smooth except for long dark rifts along the trunk and the branches as well as a few dark holes.

Behind the block and the dark blue rails along the stairs by the right-hand edge of the image, a gigantic version of the unidentified shrubs in the planters is located on the edge of the downhill slope which necessitates the stairs. It is about five and a half metres or eighteen feet high, and its flowers are up to 60 centimetres or two feet in diametre.

Farther in the background, also behind the lamp post and a little behind the shrubs, there is a group of seven pine trees of varying size. They have semi-transparent, conical surfaces around their trunks with textures which give the impression of very dark green needles. There are also bushels of tall grass on the ground between the pines.

Lastly, one of the four main light sources is the simulated Sun. Since it is shortly before noon, it is standing almost vertically above the sim and shining what is technically grey light down on it. The sim uses OpenSim's default daycycle in which the Sun always goes through the zenith. The same applies to all converted older daycycles originally available in OpenSim. The Sun is also the only light source on the sim whose light casts shadows. The other four main light sources are three types of ambient light in darker taupe, bluish slate grey and Prussian blue. These three neither have a specified direction of light, nor do they produce any shadows.

If you see Robert pimp in his red Mustang cabrio at landing point don't hesitate to drive with him. He is doing a 35 min tour with you and even shows you the red light district, where he owns most of the clubs lol He is harmless. Perhaps he will become the first NPC movie star in virtual world haha
I was shopping with NPC Robert. For a virtual movie star he needs appropriate clothes and as virtual movie pimp fitting as well. haha But he seems to be jealous now that I cuddle with Jimmy lol
NPC Robert now also drives a new red Mustang cabrio and not his old 1972 Chevy anymore. I will show him some taste haha
Now 7 cars drive through the red light district. most of them stop there. Two of them drive from landing point (Stanley in his TransAM and Robert in his red Mustang Cabrio) and one from airport (self driving Tesla Model S).

And if I'm going to describe in more details what's standing around the small landing platform in the image in the image, I'll also have to copy-paste my OpenSimWorld beacon explanation and modify it. Which means another 5,000 characters or so. And I am already over 40,000, not even counting the preamble.

#OpenSim #OpenSimulator #Metaverse #VirtualWorlds #ImageDescription #ImageDescriptions #ImageDescriptionMeta #CWImageDescriptionMeta

Okay, I'm back at it.

I've just realised that if I mention avatar accessories, I also have to explain that OpenSim avatars aren't monolithic and what they're made from. So I did. In over 4,000 characters.

If I don't describe and post the aerial view, and I merge the preamble with the description, this will become my longest image description by a wide margin.

I just realised I can rez on this sim.

Now I'm wondering: Shall I go on guesstimating dimensions, or shall I rez a block, measure them all way more precisely and enter dimensions with a precision of under one centimetre in my image descriptions?

#OpenSim #OpenSimulator #Metaverse #VirtualWorlds #ImageDescription #ImageDescriptions #ImageDescriptionMeta #CWImageDescriptionMeta

I had an idea. I think I've found something.

Namely the famous Universal Campus or rather the main building.

Spectacular: yes. Well-known in OpenSim: yes. Complex: yes, but not too much.

And I'll probably do two pictures again.

Now I'm looking around Nantucket, a sim on 3rd Rock Grid of which I'm not sure whether it has been rescued, or whether it'll go down with the grid this week.

The Nantucket Federal House looked tempting, also because it has neither furniture nor walls inside, but parts of it are too complex to describe, and I can't properly describe Art Nouveau items either.

#OpenSim #OpenSimulator #Metaverse #VirtualWorlds #ImageDescription #ImageDescriptions #ImageDescriptionMeta #CWImageDescriptionMeta

Took a trip outside OSgrid to Sendalonde. I considered actually showing and describing the famous library building.

I won't. Not only due to highly complex abstract textures on the building that I couldn't possibly describe even if I tried, but mostly due to the huge dragon statue. Which means eye contact. I can't even show pictures of the library.

#OpenSim #OpenSimulator #Metaverse #VirtualWorlds #ImageDescription #ImageDescriptions #ImageDescriptionMeta #CWImageDescriptionMeta

My current plan is to stay in OSgrid, so another idea was Tropicana Bird's Nest which is more than just inspired by American Graffiti.

I won't do that either, though. I can't just name-drop the automobiles standing around. How is a blind or visually-impaired Fediverse user supposed to know what a '58 Chevy Impala looks like? Or that modified '32 Ford Deuce Coupe?

#OpenSim #OpenSimulator #Metaverse #VirtualWorlds #ImageDescription #ImageDescriptions #ImageDescriptionMeta #CWImageDescriptionMeta

I thought I'd found something, namely the NyAlfheim harbour. Still extremely detailed, but I thought it's doable.

But there's this small box with a sailing boat inside. It's half-obscured by a lamp post, but it shows two different textures on the sides. Both textures show the same boat with different scenery.

No way I can describe it properly.

#OpenSim #OpenSimulator #Metaverse #VirtualWorlds #ImageDescription #ImageDescriptions #ImageDescriptionMeta #CWImageDescriptionMeta

I've launched my next image post project. Yes, what'd take you seconds will take me at least one day. And what you may do every couple of minutes, I haven't done in over three months due to the effort.

And I mean the effort of describing the image.

Since the sims of 3rd Rock Grid are being rescued and largely already have been, there's no point in showing one of them anymore. So I'm looking for a motive elsewhere.

It's hard to find something that's interesting to look at while still not impossible for me to describe adequately before the end of the day.

I'm currently looking around NyAlfheim in OSgrid. I've found a scene that's absolutely gorgeous. But it'd also absolutely be hell to describe, what with all the different buildings and what's inside the buildings and the furniture in front of the buildings and the boats and all the other decoration.

Also, there are static human figures plus one human animesh figure in the scene which means eye contact which, in turn, means I'd have to link to the image instead of embedding it because that's the only way I have to hide the image from sensitive Mastodon users.

On the other hand, I don't want to show something that's so simple that it's lacklustre and not a bit interesting.

Okay, the mystery is solved. I've managed to catch someone from 3RG.

The big event that Alia wanted never had a chance to materialise. All they managed to do was a farewell party in 3RG yesterday. Today there's nothing. And the welcome party in ZetaWorlds will be at some point in the next weeks.

They didn't even manage to advertise or communicate anything. I guess they had no Hypergridders yesterday, only residents.

Oh well, good thing there are more events around the Hypergrid this evening.

#Long #LongPost #CWLong #CWLongPost #OpenSim #OpenSimulator #Metaverse #VirtualWorlds #3rdRockGrid

Imagine there's a farewell party for one of the oldest grids, and nobody attends it because nobody knows it's happening, much less where and when.

I'm trying to figure out where the 3rd Rock Grid farewell/3rd Wind welcome event takes place. There is practically zero advertisement for it. There's none on OpenSimWorld, there's none in-world in 3rd Rock Grid, there's none in-world in ZetaWorlds. There's only a fleeting mention in the HG Safari post about 3rd Wind. And the when and where is mentioned by Alia Soulstar in a comment, but only for yesterday.

Starfleet Infinity where the part of the event yesterday took place doesn't exist in ZetaWorlds yet. There's a big varsim named Infinity, but that one has got multiple event spaces and no announcement signs anywhere. Apparently, the plan is either for everyone to teleport over from 3rd Rock Grid in the middle of the event and be told where the party continues right there, right then, or the Saturday visitors were told that the event continues elsewhere today.

One of the event locations, the only one apparently permanently staffed with an NPC DJ, is under a dome with mostly water under it. The dance floor is a number of square pads in the middle, but you have to run and jump to get to it. At least the water is shallow, so no need to swim, but anything significantly longer than hot pants or a micro-miniskirt might get wet if you end up in the water.

Well, then I went to the original Starfleet Infinity where the event was scheduled yesterday. I had to walk to the rough coordinates from the blog comment. There were no traces of an event, there were no announcements, but there was that self-same domed building. I think I might not wear nylons to this party.

My friend has been advocating for quite a while, that we should be including alt text in our images, describing the scene for vision impaired readers. I am going to try to be better about doing it, and I encourage others to do so as well.

Below is a picture of our railroad in our virtual world, GroovyVerse.

Story of NPC Robert how it all begun ...

This video of NPC Robert is made with NPC Companion 3.03 on Big City Life in opensim. All you see in action with NPC Robert is made live while recording. It is just cut out any blue menus or appearing couple walk hud. The couple Walk inside of NPC Companion is still alpha version 0.5. But we hope to come soon to regular 1.0 version with more animations and better adjustments especially for much different Avatar sizes like you see in this video. But it is already usable. So we decided to release NPC Companion with the alpha version of couple walk inside. It is not perfect. But you can do already a lot of things with it.
