This directory contains common auxiliary files used by Radiance. Files
|
| 2 |
|
|
with the ".cal" suffix specify procedural patterns, textures and coordinate
|
| 3 |
|
|
mappings. Files with the ".fnt" suffix are font descriptions. Files
|
| 4 |
|
|
with the ".oct" suffix are compiled scene descriptions for use in
|
| 5 |
|
|
instances. Files with the ".mat" suffix contain the names of materials
|
| 6 |
|
|
used in the corresponding ".oct" file, for exclusion in the interreflection
|
| 7 |
|
|
calculation using the -aE rendering option. Files with the ".pic" suffix
|
| 8 |
|
|
are images for patterns. Note that most pictures are normalized to a
|
| 9 |
|
|
value of 1 rather than the more usual .5, and must be displayed with
|
| 10 |
|
|
the -e -1 option. This is so the material reflectance given in the
|
| 11 |
|
|
scene description holds true. (Suggested reflectances are given in
|
| 12 |
|
|
parentheses.)
