Practical and theoretical implementation discussion.
1 post • Page 1 of 1
I'm a bit curious about octane pmc implementation. Anyone care to speculate on how they use pmc? It's probably going to be for per pixel noise reduction and perhaps for selecting light sources etc but my guess is that they don't use something similar to pmc-er. What do you think? Could they use something to target caustics and other non direct light sampling. If so, is pmc process applied per vertex or per path, ie is it something used for several samples?
