Description

Methods

	function DeepCopyCore(CopyState: TX3DNodeDeepCopyState): TX3DNode; override;

	destructor Destroy; override;

	procedure OptimizeControlPoints( const CopyOptimizedDataFrom: TAbstractCubicBezierInterpolatorNode = nil);
Once the FdControlPoints value is settled, call this to precalculate curve parameters. This makes the following interpolation using this node work fast. You can pass CopyOptimizedDataFrom if you have a copy of this node (with exactly equal FdControlPoints) from which we could copy optimized data.

	procedure CreateNode; override;
Create node fields and events.

	class function ClassX3DType: String; override;

	procedure SetControlPoints(const Value: array of TVector4); overload;

	procedure SetControlPoints(const Value: TVector4List); overload;

Properties

	property FdControlPoints: TMFVec4f read FFdControlPoints;
Internal wrapper for property ControlPoints. This wrapper API may change, we advise to access simpler ControlPoints instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).
