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 get-
       info(1) if an octree exists for the scene.  However, there are certain circumstances, such as foreign object placement, that require  know-
       ing the bounding box rather than just the bounding cube.
