SoExtSelectionOnPreFilter Event |
The ExtSelection will traverse each node of scene graph and test intersection against each nodes.
Namespace: OIV.Inventor.Nodes
The event is called before doing intersection test and can be used to skip a particular node to avoid doing costly computation. To skip a node, call the method OIV.Inventor.Nodes.SoExtSelection.PreFilterEventArg.SkipNode() inside your callback.
