Parallel Progressive Radiosity with Adaptive Meshing

WebWe have developed a radiosity system that computes radiosity solutions for very large polygonal models. The first innovation in this system is that it uses visibility oracles and hierarchical methods to: 1) reduce the number of polygon-polygon interactions considered, and 2) partition the computation into a sequence of subcomputations each requiring a … WebFeature-based Control of Visibility Error: A Multi-resolution Clustering Algorithm for Global Illumination Fran˘cois Sillion , George Drettakis circle waveform equalizer_freeWeb1 de jan. de 1993 · A rapid hierarchical radiosity algorithm.
