PointOnCurve2d Class

This class represents points along 2D curves. The point representation includes its parameter value, its coordinates, and the derivatives of the curve at that point. For more information, see Working with Evaluator Classes.

The PointOnCurve2d type exposes the following members.

Constructors

	Name	Description
	PointOnCurve2d	Default constructor for the PointOnCurve2d class. Creates a default corresponding C++ object with a point that does not lie on any curve and has a parameter value of 0.
	PointOnCurve2d(Curve2d)	Constructor for the PointOnCurve2d class. Creates a point on the specified curve. Parameter value for the point on the curve is 0.
	PointOnCurve2d(Curve2d, Double)	Constructor for the PointOnCurve2d class. Creates a point on the specified curve with a provided parameter value.

	Curve	Property that represents handle to a constant curve on which the point lies.
	IsDisposed	Property that indicates whether pointer to native code unmanaged object == IntPtr::Zero. (Inherited from DisposableWrapper)
	Parameter	Property that represents the parameter value of this point on the curve.
	Point	Property that represents the point on the curve.
	UnmanagedObject	Property that represents a pointer to an unmanaged object. (Inherited from DisposableWrapper)
