Ray tracing

Recently, I'm working on the ray tracing assignment of cmpt361. Ray tracing is a very interesting algorithms for rendering; it does not need 3D transformation. Instead, it uses each ray from a camera ( or a eye ) to calculate each pixel. Another feature is that it recursively calculates specular reflection, and then get more realistic picture.

One big drawback of ray tracing algorithms is that it can not be used in real-time render because it need too much time. Otherwise, quality of computer games will be much better.
