WebShading is applying lighting effects in OpenGL code. The three ways below are in increasing realism, but also each take a higher performance hit. Flat Shading Gouraud Shading Phong Shading Comparison of shading and normals In summary, it’s something like this: 3.2.1. Flat Shading ¶ WebThis was for a project that I've recently handed in and would like to get some more information as to what I've done wrong to further my understanding.. I've written code with a point source for lighting elements. The problem that I'm having is that the shininess attribute of the material is doing nothing for my specular lighting (if its 10.0 or 200.0).
