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