# Objective - Start the realtime direct lighting work for bevy solari ## Solution - Setup all the CPU-side code for the realtime lighting path (minus some parts for the temporal reuse I haven't written yet) - Implement RIS with 32 samples to choose a good random light - Don't sample a disk for the directional light, just treat it as a single point. This is faster and not much worse quality. ## Future - Spatiotemporal reuse (ReSTIR DI) - Denoiser (DLSS-RR) - Light tile optimization for faster light selection - Indirect lighting (ReSTIR GI) ## Testing - Run the solari example to see realtime - Run the solari example with `-- --pathtracer` to see the existing pathtracer --- ## Showcase 1 frame direct lighting:  Accumulated pathtracer output:  --------- Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com> |
