Fast Global Illumination Baking via Ray-Bundles - Picture

Fast Global Illumination Baking via Ray-Bundles


This sketch presents a simple and fast renderer for light maps. Our system exploits ray-bundles on DirectX11 Graphics Processing Units (GPUs) and outperforms ray tracing. Furthermore, it supports tessellation for DirectX11 games.

Bidirectional Light Transport with Vertex Merging - Picture

Bidirectional Light Transport with Vertex Merging


Carrying the advantages of photon mapping, our new path sampling technique extends the bidirectional path tracing framework to efficiently handle lighting conditions ranging from diffuse inter-reflections to reflected caustics.
