Optimizing Path Termination for Radiance Caching Through Explicit Variance Trading
Proceedings of the ACM on Computer Graphics and Interactive Techniques (PACMCGIT), Volume 7, Issue 3Article No.: 33, Pages 1–19https://doi.org/10.1145/3675381Radiance caching allows to amortize the cost of path tracing by sharing contributions of path suffices in a spatial data structure. This sharing generally introduces bias, but it can be traded with variance by terminating into the cache at deeper path ...

PLOC++: Parallel Locally-Ordered Clustering for Bounding Volume Hierarchy Construction Revisited
Proceedings of the ACM on Computer Graphics and Interactive Techniques (PACMCGIT), Volume 5, Issue 3Article No.: 31, Pages 1–13https://doi.org/10.1145/3543867We propose a novel version of the GPU-oriented massively parallel locally-ordered clustering (PLOC) algorithm for constructing bounding volume hierarchies (BVHs). Our method focuses on removing the weaknesses of the original approach by simplifying and ...
