procedural textures
Procedural textures are textures (yep, you guessed right 
) that are rendered using a procedure...
This mean that your code is producing a texture using a few parameters to generate it.
This allow you to use fractals at different LOD, for example, or to create a ''living'' skydome in which the sun move as the clouds...
You can get more informations by looking for the RenderMan shading language.
Additionnaly, an OpenGL extension have just been created that use 3D accelerated hardware to emulate the RenderMan shading language.
(Which is based on raytracing, rather than polygons)
-* So many things to do, so little time to spend. *-

hey Ingenu, OpenGL Shader sounds cool to me but i don''t have an Irix 6.5... Do you have any information of a possible port of the OpenGL Shader SDK on win95/98/2000/NT?

Unfortunately I don''t have any information about ports.
But if it''s OpenGL, it might be cross platform or easily ported.
Too me it seems that only 3D Hardware having pixel/certex shaders can do the trick...
So it''s not really for today.
(Not enought people have vertex/pixel shading capable cards)
