# getbbox(1)

compute bounding box for RADIANCE scene

## 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)](/oconv/1.md)* and read by *[getinfo(1)](/getinfo/1.md)* 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.
