Information Theory Tools for Scene Discretization
(The Eurographics Association, 1999)
Finding an optimal discretization of a scene is an important but difficult problem in radiosity. The efficiency of hierarchical radiosity for instance, depends entirely on the subdivision criterion and strategy that is ...
Gathering for Free in RandomWalk Radiosity
(The Eurographics Association, 1999)
We present a simple technique that improves the efficiency of random walk algorithms for radiosity. Each generated random walk is used to simultaneously sample two distinct radiosity estimators. The first estimator is the ...
