Interface ArcByCenterPoint

All Superinterfaces:

CurveSegment

All Known Subinterfaces:

CircleByCenterPoint

All Known Implementing Classes:

DefaultArcByCenterPoint, DefaultCircleByCenterPoint

public interface ArcByCenterPoint
extends CurveSegment

Circular CurveSegment that consists of a single arc only.

This variant of the arc requires that the points on the arc have to be computed instead of storing the coordinates directly. The control point is the center point of the arc plus the radius and the bearing at start and end. This representation can be used only in 2D.
