It is therefor up to everyone’s own discretion to keep an eye on the complexity of their objects, (as it was with prims and sculpties before). OpenSim does as of today not support this new impact calculator, which means every single mesh object counts as 1 prim. To leverage them better, SL introduced a new mode of calculating the “ land impact” (the impact an object has on the server) which is based on its complexity (both visual and physical) and size (both in data and in-world simulated size). Now, basically any shape, detail and complexity is possible in both Second Life and OpenSim, which brings along its own kinds of problems and possibilities. They cannot have any number of vertices, but need to conform to the image sizes and resolutions, as well as the positions on the image file.īy supporting other mesh types, these restrictions finally have been overcome. Unlike primitives, they allow direct editing of their vertices, but are limited by the specific way they need to be represented, i.e.

Sculpted prims are a special kind of mesh, whose vertex positions are defined by a texture. They are great to start building right away without knowing anything about vertices or 3d-modelling, but they will not allow the freedom and level of detail that mesh-modelling allows. In contrast to any other meshes, primitives (or “prims”, as they are usually called) are simple, predefined 3D-objects whose shape cannot be altered by editing the vertices themselves, but only in simple, preconfigured terms (like the in-world editor). These triangles describe the shape of the world, they form the “mesh” of surfaces that the viewer displays to us and which we perceive as three-dimensional objects. This will remove the surface textures and show the vertices the world is made up of. The easiest way to understand this is to turn on wireframe mode in the viewer (ctrl + r on PC, cmd + r on a Mac). Thus, everything we encounter inworld, be it avatars, objects, wearables, prims, sculpts, whatever, are meshes. mesh”, since both prims and sculpts are meshes, albeit special ones. What is a mesh? A mesh is a description of a three-dimensional object in a simulated space.
