inline

Constructor.

Creates a polynomial Bezier curve.

thePoles and must belong to [2, 26]. Created curve has a degree equal to theNumberOfPoles - 1.

◆ BezierCurve2d() [2/2]

cadex.Geom.BezierCurve2d.BezierCurve2d ( cadex.Collections.Point2dList thePoles,
cadex.Collections.DoubleList thePoleWeights )
