Parallel progressive photon mapping on gpus

WebJun 14, 2024 · In gather pass, each GPU just read its own photon map. With applying a kd tree construction on each GPU independently, the whole photon map construction could be duplicated on each GPU to avoid writing to PCIE. I am not sure how Optix 5.0 could do this right now, it could be achieved with two features: WebWe present a modied photon mapping algorithm capable of running entirely on GPUs. Our implementation uses breadth-r st photon tracing to distribute photons using the GPU. The photons are stored in a grid-based photon map that is constructed directly on the graphics hardware using one of two methods: the r st method is a multipass
