README

LIBRARIES This directory contains favorite library files (a.k.a. auxiliary files) used by Radiance, including procedural patterns and textures, scanned patterns, fonts, compiled objects and so on. Each file in this directory is a compressed tar file with the name of the person or entity who made the contribution. These files should unpack to create a directory by the same name containing the various submission that person or entity has to offer. There should also be included a README file saying what each file is. When naming auxiliary files, the following conventions should be followed as closely as possible. Files with the ".cal" suffix specify procedural patterns, textures and coordinate mappings. Files with the ".fnt" suffix are font descriptions. Files with the ".oct" suffix are compiled scene descriptions for use in instances. Files with the ".pic" suffix are images for patterns. Pictures for use as patterns are normalized to a value of 1 rather than the more usual .5, and must be displayed with the -e -1 option. This is so the material reflectance given in the scene description holds true. The exception to this is pictures that are not meant to be used as repeated patterns, but instead as paintings or pictures to hang on the wall. If you wish to make a contribution to this directory, please look at the tar file gward.tar.Z as a model.
