Documentation

This single-pass effect implements a sort of anisotropic lighting that replaces the standard OpenGL lighting model. The final color of vertices is not computed directly, it is the result of a texture lookup on a user-supplied lighting image map. A vertex program is used to compute the s and t texture coordinates as follows: s = (N dot H) ; t = (N dot L) where N is the vertex normal, L is the light-to-vertex vector, H is the half-way vector. This is a good example of how you can use the State::getInitialViewMatrix() method to retrieve the view matrix and perform view-dependant effects without fakes of any kind. This effect requires the ARB_vertex_program extension.
