متن کاملReal-Time Photon Mapping on GPU
This paper presents a hybrid photon-mapping approach for global illumination . It represents a significant improvement over a previously described approach, both with respect to speed and accuracy. Using OptiX for ray tracing provides a considerable improvement in the speed of ray tracing and would keep synchronization to a minimum by using texture memory to cache access to the photon informati...
متن کاملReal-time Gpu Photon Mapping
Photon mapping, an algorithm developed by Henrik Wann Jensen [1], is a more realistic method of rendering a scene in computer graphics compared to ray and path tracing. Unlike ray tracing, photon mapping first emits lots of photons from light sources in a scene and then uses the photon map to calculate the radiance of each pixel in the rendered scene. Previous work in the area include a GPU pho...
