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. AUTHOR
