Pathtracing and Global Illumination



On the January 28th 2015, Dragan Okanovic talked about path tracing and global illumination.

Presentation briefly covered problems that computer graphics is trying to solve, such as what light actually is and how to model it, and rendering equation that is trying to solve (Kajiya). Whitted raytracer implementation, Monte Carlo approximation for GI were mentioned and also various ways to more efficiently get to the solution with MC methods – Metropolis Light Transport, Bidirectional pathtracing, Photon Mapping and various acceleration structures (BVH, K-d tree, Octree) were also discussed.
