Fast Caching Lighting Preview System

Advisor: Prof. Hong Qin

Developed a lighting preview system which preprocesses the shader code before shading actually starts. This is specially helpful for fixed-view relighting. Shader code specialization helps in separating the static processing (e.g. texture maps, normal maps etc.) from the dynamic computations dependent on light. The cached computations which are stored in form of maps need not be calculated with changing light. This made it good for iterative scene relighting. Testing has been performed on ARB shaders and the improvement is shown in the video.
