lookamb - examine ambient file values
lookamb [ -d ][ -r ][ -h ] [ ambfile ]
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.
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.
