dcterms:description
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 indirect illumination. Our method improves photon density estimation, which is an approximate solution, and leads to significantly better visual quality in particular for complex geometry, while only slightly increasing the computation time. We perform direct splatting of photon rays, which allows us to use simpler search data structures. Our novel lighting computation is derived from basic radiometric theory and requires only small changes to existing photon splatting approaches.
