DESCRIPTION
       This engine computes the	bounding box and center	of a scene graph.  The
       scene graph can be defined by a path or by a root node.

       If the path input is not	NULL, the bounding box of the graph defined by
       the path	will be	computed. If path is NULL, but the node	input  is  not
       NULL,  the bounding box is computed on the graph	rooted by the node. By
       default,	the two	inputs are NULL. If both the inputs are	NULL, the out-
       puts are	disabled.

       The  engine  uses  a  default  viewport	region.	 If the	graph includes
       screen-based objects (such as SoText2) you can call setViewportRegion()
       on the engine instance to set up	the correct viewport region to use.

INPUTS
     SoSFNode		 node
	  Defines the graph for	which the bounding box is computed.

     SoSFPath		 path
	  Alternatively,  defines the graph for	which the bounding box is com-
	  puted.

OUTPUTS
     (SoSFVec3f)	 min
	  Minimum point	of the computed	bounding box.

     (SoSFVec3f)	 max
	  Maximum point	of the computed	bounding box.

     (SoSFVec3f)	 boxCenter
	  Center of the	computed bounding box.

     (SoSFVec3f)	 objectCenter
	  Center of the	objects	in the graph.

METHODS
			       SoComputeBoundingBox()
	  Constructor

     void		       setViewportRegion(const	      SbViewportRegion
				    &vpReg);
	  Sets the viewport region to use for the bounding box computation.

     const SbViewportRegion &  getViewportRegion();
	  Returns the viewport region to use for the bounding box computation.

FILE FORMAT/DEFAULTS

	  node	NULL
	  path	NULL
     }
