Global Illumination, Path Tracing, Photon Mapping and Ray Tracing all belong to a category of algorithms that are better suited for multi-core general processors -- not the SIMD hardware of today's GPUs.
- dogma1138 11y agoGPU's haven't stuck to SIMD parallelism for quite a few years now. NVIDIA is not there yet SMT/DPT isn't true parallelism but it's good enough even for path tracing. AMD GPU's are pretty much truly parallel with every execution unit capable of executing any instruction asynchronously.
