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 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.

Specified by:: parallel in interface CirculinearContinuousCurve2D
Specified by:: parallel in interface CirculinearCurve2D

Parameters:: d - the distance between the original curve and he parallel curve.
Returns:: the parallel curve

transform

CirculinearElement2D transform(CircleInversion2D inv)

Description copied from interface: CirculinearShape2D

Transforms the shape by a circle inversion. The result is still an instance a CirculinearShape2D.

Specified by:: transform in interface CirculinearContinuousCurve2D
