Efficient radiosity rendering using textures and bicubic reconstruction
Rui Bastos, Michael Goslin, Hansong Zhang · 1997
Wepresenta method to speed up walkthmttghs of static scenes.It involves the cmatiort of acmttimsous C1 radiosity reconstruction for adaptively sampled tegiotts.This mpmaentation is a unitied solution to handle usuestricted quadtrees and T-vertices, and allows for the generation of multiple different levels-of-detail of the radiosity function, which are represented as texture maps.The method also involves the use of hardwase bicublc filtering for the mdiosity shading.Both techniques allow improvenmts in performance and memory usage while preserving visual appearance.
