to do displacement mapping on a object (head.obj), for which i cannot
give tex cood for each vertex from the program.
i already have:
a displacement map and code of how to do disp mapping in vertex, and
what i do need:
a texel.st value to pass on to
i want the texture to stick to the object, and not move with the
camera, or object rotation. simulation of texgen parameter
does any of u know, how to figure out the texel value in the vertex
using the vertex position as the reference possibly?
i already tried:
gltexgen - wont work since it is a fixed functionality.
