Detailed Description

This is the abstract base class from which all scene graph node classes are derived.

Action Behavior

: SoSearchAction
If the node pointer, type, or name matches the search criteria, returns a path to the node.

: SoWriteAction
Writes the contents of the node to the current SoOutput.

virtual SoNode * SoNode::addToCopyDict ( ) const

virtual

Returns the copy of this node.

Reimplemented in SoBaseKit, and SoUnknownNode.

◆ affectsState()

virtual bool SoNode::affectsState ( ) const

virtual

The default method returns TRUE. Node classes (such as SoSeparator) that isolate their effects from the rest of the graph override this method to return FALSE.

Reimplemented in SoInteractionKit, SoNodeKitListPart, SoSceneKit, SoSeparatorKit, SoArray, SoMultipleCopy, SoSeparator, SoShape, and SoSwitch.

◆ callback()

If the node is a group, it copies the children as well. If copyConnections is TRUE (it is FALSE by default), any connections to (but not from) fields of the node are copied, as well. Note that multiple references to a node under the node to be copied will result in multiple references to the copy of that node.
