.TH GETBBOX 1 11/15/93 RADIANCE
.SH NAME
getbbox - compute bounding box for RADIANCE scene
.SH SYNOPSIS
.B getbbox
[
.B \-w
][
.B \-h
]
[
.B "input .."
]
.SH DESCRIPTION
.I Getbbox
reads each scene description
.I input
and computes the minimum axis-aligned parallelopiped that
will enclose all of the objects.
Each
.I 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.
.PP
The
.I \-w
option suppresses warnings.
The
.I \-h
option suppresses the header line "xmin xmax ymin ymax zmin zmax".
.SH EXAMPLE
To compute the bounding box for the object ``thingy'':
.IP "" .2i
getbbox thingy
.PP
To preview ``scene'':
.IP "" .2i
preview -v FOUR -b `getbbox -h scene` scene
.SH NOTES
Since expanding a scene can require considerable overhead, it
is better to use the bounding cube produced by
.I oconv(1)
and read by
.I 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.
