At the Advanced Graphics Summit during GDC 2023, Guillaume Boisse, a Senior Graphics Programmer at AMD, will be presenting a session titled “Two-Level Radiance Caching for Fast and Scalable Real-Time Dynamic Global Illumination in Games.” The session will be held in Room 301, South Hall, on Monday, March 20, from 2:40 pm to 3:40 pm. The presentation will be accessible to those with an All Access Pass or a Summits Pass. Real-time global illumination is essential for creating dynamic and believable game worlds. Although GPU-accelerated ray tracing has made this possible, framerate and resolution requirements limit the number of traceable rays per pixel, which imposes practical constraints on current hardware generations. Existing solutions, like probe-based techniques, suffer from reduced details and slow response times to lighting changes, while reservoir-based resampling techniques generally have poorer performance and increased noise. In his presentation, Boisse will demonstrate the practical implementation of a solution that maximizes the use of every sample by caching the estimated radiance into a cache hierarchy for both sampling and filtering. This approach allows for high-quality, dynamic, leak-free global illumination without the need for content pre-processing, making it easy to integrate into existing real-time rendering pipelines. This innovation has the potential to significantly improve the visual quality of games while maintaining high performance on current hardware. https://twitter.com/GPUOpen/status/1636360385547898880 Developing…
