Global Illumination Raytracer
A few students of the global illumination course could demonstrate their skills with renders instead of the exam. I also built an engine that was able to render both global and local illumination. The engine accepted a scene and produced an image. I also developed a script editor for more sophisticated scene editing.
The global illumination engine is based on the Monte-Carlo integral so it is painfully slow. After some calculations and experiments I developed a stochastic rendering technology, where the image is the result of a convergence procedure. The method uses scan-lines, but in a fashion that gives you a global impression very soon.
