Title:
Radiosity Methods for Volume Rendering
Author:
Holly E. Rushmeier
Abstract:
Radiosity methods are techniques for calculating radiative transfer.
They were originally introduced in the field of heat transfer, and are
descibed in many heat transfer textbooks (e.g. the undergraduate text by
Incropera and Dewitt (1990), or the graduate text by Siegel and Howell
(1981)). Since calculating global illumination is a radiative transfer
problem, radiosity methods have been adapted to image synthesis,
beginning with the work of Goral et al. (1984) and Nishita and Nakamae
(1985). Over the past seven years many papers describing variations of
the radiosity method for rendering surfaces have been published. In
these notes, the use of these variations for rendering volumes will be
considered. This material can be found in more detail in Rushmeier and
Torrance (1997) and Rushmeier (1988).
