Fast Algorithms for Volume Ray Tracing
John Danskin and
Pat Hanrahan
Abstract
We examine various simple algorithms that exploit homogeneity and
accumultaed opacity for tracing rays through shaded volumes. Most of
these methods have error criteria which allow them to trade quality for
speed. The time vs. quality tradeoff for these adaptive methods is compared
to fixed step multiresolution methods. These methods are also useful
for general light transport in volumes.
