Constructor Detail

CirculinearCurveSet2D

public CirculinearCurveSet2D()

Empty constructor. Initializes an empty array of curves.

CirculinearCurveSet2D

public CirculinearCurveSet2D(int n)

Empty constructor. Initializes an empty array of curves, with a given size for allocating memory.

CirculinearCurveSet2D

public CirculinearCurveSet2D(T[] curves)

Constructor from an array of curves.

Parameters:

curves - the array of curves in the set

CirculinearCurveSet2D

public CirculinearCurveSet2D(Collection<? extends T> curves)

Constructor from a collection of curves. The curves are added to the inner collection of curves.

Parameters:

curves - the collection of curves to add to the set

Method Detail

getLength

public double getLength()

Specified by:

getLength in interface CirculinearCurve2D

Returns:

the length of the curve

getLength

public double getLength(double pos)

Specified by:

getLength in interface CirculinearCurve2D

Returns:

the length from the beginning to the position given by pos

getPosition

public double getPosition(double length)

Specified by:

getPosition in interface CirculinearCurve2D

Returns:

the position located at distance 'length' from the origin

getBuffer

public CirculinearDomain2D getBuffer(double dist)

Description copied from interface: CirculinearShape2D

Computes the buffer of the shape, formed by the set of points located at a distance from the shape that is lower or equal to d.

Specified by:

getBuffer in interface CirculinearShape2D

Parameters:

dist - the maximal distance between a point of the buffer and the shape

Returns:

the buffer of the shape

getParallel

public CirculinearCurve2D 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.

Specified by:
