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).

◆ outside()

bool SbBox3d::outside ( const SbMatrixd MVP,
int &  cullBits 
) const

"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).
