Description

Methods

	function TrianglesCount(State: TX3DGraphTraverseState; ProxyGeometry: TAbstractGeometryNode; ProxyState: TX3DGraphTraverseState): Cardinal; override;

	function InternalTexCoord(State: TX3DGraphTraverseState; out ATexCoord: TX3DNode): boolean; override;

	function Lit(State: TX3DGraphTraverseState): boolean; override;
Do we have enough normals information to render this node lit. VRML 1.0 specification explicitly mentions that IndexedLineSet is treated specially: it's unlit if there are not enough normals specified.

	procedure CreateNode; override;
Create node fields and events.

	class function ClassX3DType: String; override;

	class function ForVRMLVersion(const Version: TX3DVersion): Boolean; override;
