Progressive Light Transport Simulation on the GPU: Survey and Improvements
Original language description
/Graphics Processing Units (GPUs) recently became general enough to enable implementation of a variety of light transport algorithms. However, the efficiency of these GPU implementations has received relatively little attention in the research literatureand no systematic study on the topic exists to date. The goal of our work is to fill this gap. Our main contribution is a comprehensive and in-depth investigation of the efficiency of the GPU implementation of a number of classic as well as more recentprogressive light transport simulation algorithms. We present several improvements over the state-of-the-art. In particular, our light vertex cache, a new approach to mapping connections of subpath vertices in bidirectional path tracing on the GPU, outperforms the existing implementations by 30-60%. We also describe a first GPU implementation of the recently introduced vertex connection and merging algorithm [Georgiev et al. 2012], showing that even relatively complex light transport alg
