Detailed Description
3D box which has planes parallel to the major axes and is specified by two points on a diagonal. This class is part of the standard Inventor datatype classes and is used as input and output to geometry operations (see SoGetBoundingBoxAction).

The span is the total distance the box occupies along a given direction. The total distance is returned in the form of a minimum and maximum distance from the origin of each of the corners of the box along the given direction. The difference between these two values is the span.

"cullBits" keeps track of which view-volume clipping planes the box is completely inside of; if a 'parent' bounding box of this bounding box was found to be completely inside the left/right clipping planes, the low bit of cullBits will be set to zero, and this routine will not test this box against those planes. When cullBits is zero, it is a waste of time to call this function! Before calling this the first time, set cullBits to 7 (SoGLRenderAction and SoSeparator will handle this automatically for render culling).
