Research of Lighting Technology Based on the OpenGL
The manipulating technique of lighting is a very important component of realistic image rendering, including lighting model and shading. This paper, first, introduces the basic concepts, the principles and the programming of the general thoughts of Lighting with OpenGL; then, introduces how to compute the light intensity and shading interpolation by investigating the reflex factors on object surface; last, provides a set of cases to show the ideal effect with different rendering techniques.
