Radiance getbbox program

GETBBOX(1)                                                          GETBBOX(1)

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 circum-
       stances, such as foreign object placement,  that  require  knowing  the
       bounding box rather than just the bounding cube.
