Lucas Alber demonstrates real-time path tracing in Quake using a novel Markov Chain Path Guiding algorithm.
This video showcases Markov Chain Path Guiding to render Quake. Everything is purely path-traced in real-time, including the single-scattered fog. Uncompressed video files: drive.google.com/drive/folders/1qcgMkbaV2Rcr4avUpCLJavNZ_I0w… The map is ad_tears from Arcane Dimensions (moddb.com/mods/arcane-dimensions).
