[comp.graphics] Linear/Area lights

kpicott@alias.UUCP (Socrates) (11/23/89)

Has anyone seen any work done on evaluating the diffuse and specular
illumination produced by linear and/or area lights?  I have checked all the
standard sources and all information I find gets to the point where the
integration is set up and then a little hand waving is performed accompanied
by the magical words "numerically integrated".  This works but is too slow
for my purposes.  Does anyone know of any work done in different directions
(ie faster evaluation) ?
