Caustic Connection Strategies for Bidirectional Path Tracing Sebastien Speierer, Christophe Hery, Ryusuke Villemin, Wenzel Jakob March 2018 We propose a new type of sampling strategy for connection-based path tracing algorithms such as bidirectional path tracing. Classical bidirectional path tracing generally exhibits poor performance when sampling light paths involving specular transport (e.g. refraction through dielectrics). We therefore introduce specialized connection strategies that connect through chains of specular events. ... more Paper (PDF) Available as Pixar Technical Memo #18-01 |
