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.
