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.
