Methods

Modifier and Type	Method and Description
double	getFlatness(CubicCurve2D curve) Returns the square root of the getSquaredFlatness(CubicCurve2D) (so use getSquaredFlatness(CubicCurve2D) if possible instead of this one, it will be less computational intensive).
double	getFlatness(QuadCurve2D curve) Returns the square root of the getSquaredFlatness(QuadCurve2D) (so use getSquaredFlatness(QuadCurve2D) if possible instead of this one, it will be less computational intensive).
double	getSquaredFlatness(CubicCurve2D curve) Returns the maximum squared distance between the two control points and the segment defined by the curve's anchor points.
double	getSquaredFlatness(QuadCurve2D curve) Returns the square distance between the control point of the curve and the segment defined by its anchor points.
boolean	isDegenerationRobust() Always return true., and that's because the DistUtils.pointToSegSqEucDist(double, double, double, double, double, double) method is used, so if any of the anchor points is on the line defined by the anchor points but falls outside the segment, then the method will return a non-zero distance for it.
boolean	isSquaredFlatenessPreferred() Always return true.

Method Detail

isDegenerationRobust

public final boolean isDegenerationRobust()

Always return true., and that's because the DistUtils.pointToSegSqEucDist(double, double, double, double, double, double) method is used, so if any of the anchor points is on the line defined by the anchor points but falls outside the segment, then the method will return a non-zero distance for it.
