Path-Tracing on a Heterogeneous Multi-GPU Cluster

Path tracing has been an offline rendering technique ever since. With the enormous increase of speed seen with today's GPU hardware, interactive generation of images with global illumination effects becomes more and more feasible. In the near future we will probably see photorealistic computer graphic rendered in real time. While image footage was formerly created on render farms, the challenge today is distributing work across a network of machines equipped with GPUs. In this work an approach to interactive global illumination is developed by assigning bidirectional path tracing workload to graphic cards in a cluster. Finally the gained performance increase is evaluated
