Radiance lookamb program

LOOKAMB(1)                                                          LOOKAMB(1)

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-depen-
       dent  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.
