NAME

       getbbox - compute bounding box for RADIANCE scene

SYNOPSIS

       getbbox [ -w ][ -h ] [ input ..  ]

DESCRIPTION

       Getbbox  reads  each  scene  description  input  and  computes  the  minimum  axis-aligned
       parallelopiped that will enclose all of the objects.  Each input  can  be  either  a  file
       name, or a command (enclosed in quotes and preceded by a `!').  If no arguments are given,
       the standard input is read.  A hyphen ('-') can also be  used  to  indicate  the  standard
       input.

       The  -w  option  suppresses warnings.  The -h option suppresses the header line "xmin xmax
       ymin ymax zmin zmax".

EXAMPLE

       To compute the bounding box for the object ``thingy'':

         getbbox thingy

       To preview ``scene'':

         preview -v FOUR -b `getbbox -h scene` scene

NOTES

       Since expanding a scene can require  considerable  overhead,  it  is  better  to  use  the
       bounding  cube  produced  by  oconv(1)  and read by getinfo(1) if an octree exists for the
       scene.  However, there are certain circumstances, such as foreign object  placement,  that
       require knowing the bounding box rather than just the bounding cube.
