Properties

	Name	Description
	IsDisposable	ISafeDisposable interface implementation. (Inherited from SoDisposable.)
	numNodesUpToContainer	When traversed by an action, if surroundScale needs to calculate a new box, surroundScale looks at the current path in the action.
	numNodesUpToReset	Before applying the OIV.Inventor.Actions.SoGetBoundingBoxAction (see the OIV.Inventor.Nodes.SoSurroundScale.numNodesUpToContainer field above) the surroundScale node travels up the path a distance of OIV.Inventor.Nodes.SoSurroundScale.numNodesUpToReset and tells the action to reset the bounding box upon traversal of that node.
	UserData	Gets or sets the user data to be contained by the field container. (Inherited from SoFieldContainer.)

Remarks

When traversed by an action, this node appends a transformation to the current transformation matrix so that a default size cube will surround the objects specified by its fields. Transform manipulators, such as OIV.Inventor.Manips.SoHandleBoxManip, use these nodes to make themselves surround other objects.

This node only recalculates after the OIV.Inventor.Nodes.SoSurroundScale.Invalidate() method has been called. Otherwise it uses a saved scale and translation.

When calculating what to surround, the OIV.Inventor.Nodes.SoSurroundScale looks at the current path in the action and at its own field values. Then OIV.Inventor.Nodes.SoSurroundScale applies an OIV.Inventor.Actions.SoGetBoundingBoxAction to the node that is OIV.Inventor.Nodes.SoSurroundScale.numNodesUpToContainer nodes above it on the path. OIV.Inventor.Nodes.SoSurroundScale also tells the action to reset the bounding box upon traversal of the node located OIV.Inventor.Nodes.SoSurroundScale.numNodesUpToReset nodes above it in the path. The OIV.Inventor.Nodes.SoSurroundScale then appends a translation and scale to the current transformation so that a default size OIV.Inventor.Nodes.SoCube will translate and scale to fit this bounding box.

For example, when an OIV.Inventor.Manips.SoHandleBoxManip wants to surround the objects it is going to move, the scene graph will look something like this:

                   RootNode
        -------------------------
        |                       |
      handleBoxManip       movingStuff
        |
      handleBoxDragger
        |
      separator
      -----------------------------------
      |                 |               |
   motionMatrix    surroundScale     cubeGeom

The OIV.Inventor.Draggers.SoHandleBoxDragger wants to transform the cubeGeom so that it surrounds the movingStuff . So it sets the surroundScale fields to:

   numNodesUpToContainer = 4;
  numNodesUpToReset = 3;

The SoBoundingBoxAction will then be applied to RootNode , with a reset after traversing the OIV.Inventor.Manips.SoHandleBoxManip. So the OIV.Inventor.Nodes.SoSurroundScale will surround the objects below separator , and to the right of handleBoxManip , producing the desired effect.
