hi all, program goal: 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 fragment shader what i do need: a texel.st value to pass on to vec3 disp=vec3(texture2D(displacementMap,texel.st)); i want the texture to stick to the object, and not move with the camera, or object rotation. simulation of texgen parameter (object_plane) does any of u know, how to figure out the texel value in the vertex shader? using the vertex position as the reference possibly?
