Abstract:This research investigates the feasibility of a fully GPU-based photon mapping approach for real-time indirect diffuse illumination. Having designed and implemented a prototype system that uses photon mapping to compute indirect diffuse illumination, we evaluate it by measuring its performance under various configurations and in different scenes. Visual image quality is assessed by comparing produced images with high-quality reference images, using mean squared error and structural similarity measures. Computational costs are assessed by measuring average frame times. In addition to this isolated evaluation, we also compare the prototype system to other systems currently available in a number of popular game engines (relying on the same performance metrics). We conclude that even our unoptimised prototype is capable of computing indirect diffuse illumination in real-time, and that it is competitive with similar systems currently available in the commercial market.
