OptiX is a parallel system that sits on top of NVIDIA's better-known CUDA API. AFR has sampling and reconstruction processes that use information distributed across both space and time, aiming to generate low-latency updates. Previous AFR implementations were sequential prototypes. Our parallel prototype is allowing us to confront several unique challenges, including closed loop control of both sampling and reconstruction, and load balancing between CPU and GPU.CCS ConceptsComputing methodologiesRay tracing10.2312/egp.2019104513-14
