I think you are out of luck. TexGen generates the texture coordinates
down in the graphics pipe in the Geometry Engine on most SGI's. That is
why they are able to do environmental textures and projected textures so
quickly. If the CPU's had to do that work for every frame, your
performance would not be pretty. To do what you are talking about, I
think you may have to write your own code to generates texture
coordinates (don't use TexGen) before passing the geometry down the
pipe.
