Looking through the little bit that survived of th eold Wiki, there isn't much there. The Program and Michael and Victoria sections are years out of date. As I noted earlier, I converted the links in the Shader thread. Here is the section on .obj file :
A file with the .obj file extension is a three-dimensional object containing 3D coordinates, texture maps, and other object information; a standard 3D image format that can be exported and opened by several 3D image editing programs.
Hmmm... it added several extra lines when I pasted; I'm shocked... ;) At least I can now paste into a message more than once, but not more than twice, apparently.
Texture mapping is a method for adding detail, surface texture, or color to a 3D model.
A texture map is applied (mapped) to the surface of a shape or polygon. A similar idea is like placing patterned wallpaper onto a blank wall.
Multitexturing is the use of more than one texture at a time on a polygon. For instance, a light map texture may be used to light a surface as an alternative to recalculating that lighting every time the surface is rendered. Another multitexture technique is bump mapping, which allows a texture to directly control the facing direction of a surface for the purposes of its lighting calculations; it can give a very good appearance of a complex surface, such as tree bark or rough concrete, that takes on lighting detail in addition to the usual detailed coloring. Bump mapping has become popular in recent video games as graphics hardware has become powerful enough to accommodate it.
In the commercial realm, textures can be included with a 3D model or sold as standalone texture packs. These texture packs are usually assembled around a specific theme or occasion.
The Antonia page will take some work yet...
