WebMay 21, 2012 · What I tried to do was to implement this through GLSL since I already had a working implementation of Blinn-Phong reflection model with Phong shading. Basically I wanted the specular effect to be dependent on this by multiplying it with the Fresnel term. WebScene 6 is without model transformation, and Scene 7 is with model transformation. Once you finish Scene 7, you should set up your code so that Scene 6 uses the identity transform. For triangle-ray tests, ...
