SoComputeBoundingBox — computes the bounding box and center of a scene graph

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 outputs 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

SoSFNodenode
          Defines the graph for which the bounding box is computed.

     SoSFPathpath
          Alternatively, defines the graph for which the bounding box is computed.

Methods

SoComputeBoundingBox()
          Constructor

     voidsetViewportRegion(constSbViewportRegion&vpReg);
          Sets the viewport region to use for the bounding box computation.

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