Rasterizer VS Raytracer

　　Rasterizer:

　　1, real-time rendering, hard mode for optimization

　　2, OpenGL Specification in details, but not that pedagogical as PBRT

　　3, Help you understand common API like OpenGL or DirectX

　　RayTracer:

　　1, CS348b, PBRT, Ray Tracing from ground up.

　　2, Easier to implement than a rasterizer.

　　In Common:

　　1, Great Coding practice.

　　2, Wonderful feast for learning Graphics and Basic Algorithms.

　　3, Big Systems, experience for System Engineering required.

　　I will go with a raytracer.

　　PBRT is more academic.
