PROGRAM:
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 rvu(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.
