Class TTriangleFanSetNode

Unit

X3DNodes

Declaration

type TTriangleFanSetNode = class(TAbstractComposedGeometryNode)

Description

Triangles that form a fan shape around the first vertex. In constrast to TIndexedTriangleFanSetNode, this doesn't use indexes to compose vertexes into triangles.

Description

Methods

	function InternalCoordRangesCounts(out RangeCount: TInt32List; out SRanges, SRangeName: string; out RangeMinimumCount: Cardinal): boolean; 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 SetFanCount(const Value: array of Int32); overload;

	procedure SetFanCount(const Value: TInt32List); overload;

Properties

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