[Runtime Feature]: Caustics effects as in NvRTX #584

Open ladna373 opened 4 weeks ago

ladna373 commented 4 weeks ago

What is the context of the feature/improvement?

not long ago a restir fg came out which uses the same feature that was used in nvrtx and which (in my opinion) looks good, however there are some problems that are not in nvrtx (like caustics are not displayed on low roughness surface). 355117225-324917c8-cd8b-4401-98c2-dc68991ec706

Please describe the feature/improvement?

notice how surface looks in restir and how in nvrtx 355117225-324917c8-cd8b-4401-98c2-dc68991ec706 figure_1-1024x1257 (the first picture)

What would be your solution? (optional)

also, a fix might be to add hybrid shift mapping to restir fg. but the question is, which will be better, restir fg or nvrtx?
