Description

Methods

	constructor Create(const AX3DName: string = ''; const ABaseUrl: String = ''); override;

	function FieldSetByEvent(const Event: TX3DEvent): TX3DField; override;

	function CoordIndexField: TMFLong; override;

	procedure InternalCoordPolygons( State: TX3DGraphTraverseState; PolygonHandler: TIndexedPolygonHandler); override;

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

	procedure CreateNode; override;
Create node fields and events.

	class function ClassX3DType: String; override;

	procedure SetIndex(const Value: array of Int32); overload;

	procedure SetIndex(const Value: TInt32List); overload;

Properties

	property EventSet_index: TMFInt32Event read FEventSet_index;

	property FdIndex: TMFInt32 read FFdIndex;
Internal wrapper for property Index. This wrapper API may change, we advise to access simpler Index instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).
