Again, with my formatting:

Well, just remembered that you'd probably want to put your camera somewhere inside one of the XZ planes of the cube, not very close to it.

Like

<br></br>--------<br></br>        |<br></br>   X    |<br></br>        |<br></br>--------

Where the X is the camera, and the bounding box is top side of the cube.
