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.
