Comparing it with Ray-tracing using GI, the computational effort is relatively lower. This is why, Spherical Harmonics are also a fast alternative for diffuse illumination. Since Spherical Harmonics create diffuse ambient light by making the entire image brighter, you need to set Ambient Occlusion (AO) to darken certain areas. SH and AO are ...

sources and storing these as they hit surfaces within the scene. We use one high resolution caustics photon map to render caustics that are visualized directly and one low resolution photon map that is used during the rendering step. The scene is rendered using a distribution ray tracing algorithm optimized by using the in-formation in the ...

There are many reasons to augment a ray tracer with photon maps. Photon maps makes it possible to efficiently compute global illumina-tion including caustics, diffuse color bleeding, and participating me-dia. Photon maps can be used in scenes containing many complex objects of general type (i.e. the method is not restricted to tessellated models).
