Lighting
glEnable(GL_LIGHT0);
glEnable(GL_LIGHT0);
These are the common forms of lights that are used in 3D and how they work.
Light Sources : The type of light sources and how they act.
Illumination model
The illumination model is the math of how all the light parameters are mixed to get the final color on a surface.
