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  out-
       put.

       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  ambi-
       ent file.
