ReSTIR

A team project implementing ReSTIR based on the research paper with the same title, published by NVIDIA in 2020. Briefly, the purpose of ReSTIR is to help rendering scenes with a lot of lights but make it much less noisy than the basic path tracing algorithm. This is a result of continuously finding and updating the most ideal light for a pixel based on its surrounding neighbor pixels and its light in previous frames. Below are some of the results rendered using our Restir Algorithm.
