内容記述 | Photon mapping is known as one of the efficient techniques to simulate global illumination in the field of computer graphics. The photon map is used in a certain of bidirectional ray tracing. In the first place, by the ray tracing from light sources the map consists of information on a set of photons, which are emitted from the light sources and reflect/refract surfaces in a given scene. Considering the information, an image with global illumination is efficiently rendered by the ray tracing from a viewpoint. Since quality of images depends on number of photons representing illumination around them, enough photons must be generated from light sources. However, too enough photons cause long computation time. Actually, many photons are not always needed when they are located on “flat” illuminated surfaces. Therefore, an adaptive definition of photons should be developed for efficient photon mapping. Applying automatic differentiation technique to detecting edges of surfaces and emitting photons efficiently, in this paper we will propose an adaptive photon mapping algorithm, which can generate images more efficiently with global illumination including caustics, half shadows, half shades and half highlights. |
