public interface CirculinearElement2D
extends CirculinearContinuousCurve2D, SmoothOrientedCurve2D

Circulinear elements are lowest level of circulinear curve: each circulinear curve can be divided into a set of circulinear elements.

Circulinear elements can be either linear elements (implementations of LinearShape2D), or circular elements (circle or circle arcs).

Method Summary

Modifier and Type	Method and Description
CurveSet2D<? extends CirculinearElement2D>	clip(Box2D box) Clip the shape with the given box, and returns a new shape.
CirculinearElement2D	parallel(double d) Creates a new curve, formed by the points with parameterization: p(t) = c(t) + d*n(t)/|n(t)|, with p(t) being a point of the original curve, n(t) the normal of the curve, and |n| being the norm of n. In the case of a continuous curve formed by several smooth circulinear elements, the parallels of contiguous elements are joined by a circle arc.
CirculinearElement2D	reverse() Returns the curve with same trace on the plane with parameterization in reverse order.
CirculinearElement2D	subCurve(double t0, double t1) Returns a portion of the original curve, delimited by two positions on the curve.
CirculinearElement2D	transform(CircleInversion2D inv) Transforms the shape by a circle inversion.

Method Detail

parallel

CirculinearElement2D parallel(double d)

Description copied from interface: CirculinearCurve2D

Creates a new curve, formed by the points with parameterization: p(t) = c(t) + d*n(t)/|n(t)|, with p(t) being a point of the original curve, n(t) the normal of the curve, and |n| being the norm of n.
In the case of a continuous curve formed by several smooth circulinear elements, the parallels of contiguous elements are joined by a circle arc.
