Learn about the latest research in the area of many-light sampling from NVIDIA. We'll talk about reservoir spatiotemporal importance resampling (ReSTIR), which was originally presented at SIGGRAPH 2020, and achievements made since then. This algorithm makes it possible to effectively sample from millions of area lights with just a few rays per pixel and produce results that can be easily denoised. We'll also talk about the implications of many-light rendering on game content creation pipelines.
