Parallel progressive photon mapping on gpus
Webton mapping [6]. The photon mapping, which is famous ren-dering method in CG, can represent diffuse and specular in-terre ß ections based on computing emission of photons from a light. Therefore, the inverse photon mapping can estimate non-uniform re ß ectance parameters without the in ß uence of bothdiffuseandspecular interre ß ections. WebMar 20, 2013 · We describe the design space for real-time photon density estimation, the key step of rendering global illumination (GI) via photon mapping. We then detail and analyze efficient GPU implementations of four best-of-breed algorithms. All produce reasonable results on NVIDIA GeForce 670 at 1920 × 1080 for complex scenes with multiple-bounce …
