TESTS

This directory contains some test scenes and results for checking
calculations against other people's programs.  The subdirectories
are broken down according to model type as follows:

	empty/*/*	- Environments without obstructions
	obstructed/*/*	- Obstructed environments
	*/diffuse/*	- Diffuse surfaces only
	*/specular/*	- Surfaces may have some (ideal) specularity
	*/brdf/*	- Surfaces may have arbitrary BRDF's
	*/*/grey	- Grey surfaces only
	*/*/rgb		- Surfaces with RGB color
	*/*/spectral	- Surfaces with > 3 spectral samples

All models and files should be put in the bottom set of directories.
Solutions should be given in human-readable text form, and should
describe very thoroughly how they were obtained.  Please name your
files uniquely using some abbreviation of your name or group, so
we don't get name collisions when everyone starts dumping their
results into the obstructed/brdf/spectral directory (ha, ha).

There are currently Radiance-generated results in the following directories:

empty/diffuse/grey
empty/diffuse/rgb
empty/specular/grey
empty/specular/rgb
obstructed/diffuse/grey
obstructed/diffuse/rgb
obstructed/specular/grey
obstructed/specular/rgb

Most of the directories contain README files explaining their contents.
The empty/diffuse/grey directory contains results not only from Radiance,
but also from Holly Rushmeier and sometimes Sumanta Pattanaik.
