PSFPT Struct Reference

Detailed description

An implementation of a path tracer using a simplified version of Path Space Filtering. Unlike the original implementation, this version is not progressive, and relies on efficient spatial hashing for defining accumulation neighborhoods, following ideas first developed by Sascha Fricke, Nikolaus Binder and Alex Keller.

see:

Fast path space filtering by jittered spatial hashing, Binder et al, ACM SIGGRAPH 2018 Talks.
