| Abstract: | The photon mapping method is used extensively in global illumination to render photorealistic pictures. We describe a simple optimization technique for calculating the indirect illumination by modifying the photon mapping method. Using our method the photon maps are divided into several photon maps based on the topology of the polygons in the scene. This modification of the photon mapping method has several advantages compared to the traditional method. We demonstrate that the indirect illumination can be calculated faster using our method. |
