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: WebJul 7, 2014 · This approach makes each iteration/frame of PPM independent and more suitable for multi-GPU. What i do (with a single GPU) is trace a number of photons using …
