Rendering Translucent Materials

The purpose of this project was to render translucent materials using rendering techniques learnt in the Advanced Global Illumination course. We have chosen Jensen's et al.'s paper A rapid hierarchical render ing technique for translucent materials for our implementation. Jense uses an octree to evaluate irradiance points sampled uniformly across the surface of a mesh. We've used Greg Turk's Point Repulsion algorithm to sample points across the surface. Then, using the hierarchical evaluation, we sample the points that store pre-computed irradiance values using irradiance caching methods for the final rendering. The rendering was done in (a slightly modified) PBRT.
