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

CurveSet2D	clip(Box2D box) Clip the shape with the given box, and returns a new shape.
Curve2D	getParallel(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.
Curve2D	getReverseCurve() Returns the curve with same trace on the plane with parametrization in reverse order.
Curve2D	getSubCurve(double t0, double t1) Returns a portion of the original curve, delimited by two positions on the curve.
Curve2D	transform(CircleInversion2D inv) Transforms the shape by a circle inversion.

Method Detail

getParallel

Curve2D getParallel(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.
