Faster Photon Map Global Illumination
The photon map method is an extension of ray tracing that makes it able to efficiently compute caustics and soft indirect illumination on surfaces and in participating media. This paper describes a method to further speed up the computation of soft indirect illumination (diffuse-diffuse light transport such as color bleeding) on surfaces. The speedup is based on the observation that the many lo...
متن کاملGlobal Illumination with Photon Map Compensation
We present a new method for the simulation of global illumination by utilization of a photon map. It uses an advanced radiance estimation which, in contrast to classical nearest neighbor area estimation, does not assume that the nearest neighbor photons lie in one plane or that they are uniformly distributed around the illuminated point. This allows us to correcly handle indirect illumination, ...
متن کاملGlobal Illumination using Photon Maps
This paper presents a two pass global illumination method based on the concept of photon maps. It represents a significant improvement of a previously described approach both with respect to speed, accuracy and versatility. In the first pass two photon maps are created by emitting packets of energy (photons) from the light sources and storing these as they hit surfaces within the scene. We use ...
متن کاملGlobal Illumination using Photon Ray Splatting
We present a novel framework for efficiently computing the indirect illumination in diffuse and moderately glossy scenes using density estimation techniques. A vast majority of existing global illumination approaches either quickly computes an approximate solution, which may not be adequate for previews, or performs a much more time-consuming computation to obtain high-quality results for the i...
متن کاملInteractive Global Illumination using Selective Photon Tracing
We present a method for interactive global illumination computation which is embedded in the framework of Quasi-Monte Carlo photon tracing and density estimation techniques. The method exploits temporal coherence of illumination by tracing photons selectively to the scene regions that require illumination update. Such regions are identified with a high probability by a small number of the pilot...
