Michael Guthe - GPU Ray Tracing - Concepts, Advances and Challenges
19 Jun 2014 14:00-15:00
Due to the immense parallel processing power of modern graphics hardware, ray tracing algorithms and applications on the GPU have emerged. Depsite several architectural challanges, real-time recursive ray tracing has become possible. More sophisticated global illumination algorithms however still pose major challanges for efficient implementations on the GPU. After a short introduction into the programming model and the processing flow of GPUs, recent advances in real-time ray tracing will be discussed. These include acceleration data structures as well as a study of memory access and latency during intersection testing. In this context, the general problem of divergence and approaches to improve thread utilization will also be presented. The talk closes with an overview of techniques to implement more sophisticated global illumination algorithms like path tracing, bi-directional path tracing and Metropolis light transport, while putting an emphasis on the open problems in this field.
