Light Resampling in Practice with RTXDI - Part 2

Explore light resampling techniques in practice with RTXDI in this 21-minute segment from NVIDIA's comprehensive talk on rendering games with millions of ray-traced lights. Dive into the Souvenir prototype, dynamic mesh lights, light emission profiles, and the comparison between mesh and primitive lights. Examine the challenges of noise and boiling, poor initial samples, and resampling bias. Analyze spatiotemporal, spatial, and temporal resampling biases, with a focus on light data. Conclude by evaluating ReSTIR performance and its practical applications in game rendering.
