WebThey modeled specular reflection in terms of the vector H, halfway between the light and eye. If the surface was a perfect mirror and if the surface normal, N, aligned with H then the light and eye were in the right position for perfect mirror reflection. If the surface was rougher, then the specular amount was a function of what percentage was ...
