WebGlobal illumination methods such as radiosity ([GTGB84]) and photon mapping ([Jen01]) tend to be slow. Therefore, many attempts have been made to optimize the calculation of global illumination. Recently, concepts for graphics hardware acceleration of ray-tracing have been suggested ([CHH02]). http://graphics.ucsd.edu/~henrik/papers/photon_map/global_illumination_using_photon_maps_egwr96.pdf

WebPhoton maps are colored point clouds. The Indirect light can generate a photon map by shooting rays from the light and recording the shaded color of the surface at each hit point. This essentially caches the lighting, making subsequent uses of the light much faster. http://www.graphics.stanford.edu/courses/cs348b-01/course8.pdf biolyte 12-pack iv in a bottleWebDec 14, 2011 · This paper presents a two pass global illumination method based on the concept of photon maps.
