lookamb (1)
NAME
|
lookamb - examine ambient file values |
SYNOPSIS
|
lookamb [ -d ][ -r ][ -h ] [
ambfile ] |
DESCRIPTION
|
Lookamb examines an ambient file produced by
rpict(1), rtrace(1), or rview(1). The default
mode prints the position, direction, level, weight, radius,
value, position gradient and direction gradient for each
stored ambient value preceded by a label appropriate for
human interpretation. The -d option prints the same
quantities in 18 columns without any expanatory text, and is
more appropriate as input to another program. |
|
The -r option performs the reverse conversion, taking
the output of lookamb and reproducing the original ambient
file on the standard output. |
|
The -h option causes lookamb not to print out the
header information on the output, or not to expect it on the
input with the -r option. |
|
If no file is given, lookamb reads from the standard
input. |
NOTES
|
Before release 2.2 of Radiance, ambient files were in a
machine-dependent format. Since that is no longer the case,
ambient files can now be moved freely between machines
without any conversions. Thus, the only reason to use
lookamb now is to examine the contents of an ambient
file. |
