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'': |
|
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. |
