## Unit X3DNodes ## Declaration `type TLayer3DNode = class(TGroupNode)` ## Description no description available, TGroupNode description follows no description available, TAbstractX3DGroupingNode description follows no description available, TAbstractGroupingNode description follows This is a VRML/X3D >= 2.0 grouping node. This will push/pop full TX3DGraphTraverseState in Before/AfterTraverse. It also propagates DirectionalLights in any child to all children in VRML2ActiceLights. To keep X3D hierarchy, this descends from X3DChildNode. This way TAbstractX3DGroupingNode and TStaticGroupNode inherit also from X3DChildNode. ## Hierarchy TPersistent TNonRefCountedInterfacedPersistent TX3DFileItem TX3DNode TAbstractNode TAbstractChildNode TAbstractGroupingNode TAbstractX3DGroupingNode TGroupNode TLayer3DNode ## Overview ### Methods
