Class SineStarFactory

Creates geometries which are shaped like multi-armed stars with each arm shaped like a sine wave. These kinds of geometries are useful as a more complex geometry for testing algorithms.

Syntax

public class SineStarFactory : GeometricShapeFactory

Constructors

SineStarFactory()

Creates a factory which will create sine stars using the default GeometryFactory

Declaration

public SineStarFactory()

SineStarFactory(GeometryFactory)

Creates a factory which will create sine stars using the given GeometryFactory

Declaration

public SineStarFactory(GeometryFactory geomFact)

Parameters

Type	Name	Description
GeometryFactory	geomFact	The factory to use

Properties

ArmLengthRatio

Gets or sets the ratio of the length of each arm to the radius of the star. A smaller number makes the arms shorter.

Declaration

public double ArmLengthRatio { get; set; }

Property Value

Type	Description
Double

Remarks

Value should be between 0.0 and 1.0

NumArms

Gets/Sets the number of arms in the star

Declaration

public int NumArms { get; set; }

Property Value

Type	Description
Int32

Methods

Create(Coordinate, Double, Int32, Int32, Double)

Creates a sine star with the given parameters.

Declaration

public static Geometry Create(Coordinate origin, double size, int nPts, int nArms, double armLengthRatio)

Parameters

Type	Name	Description
Coordinate	origin	The origin point.
Double	size	The size of the star.
Int32	nPts	The number of points in the star.
Int32	nArms	The number of arms to generate.
Double	armLengthRatio	The arm length ratio.

Returns

Type	Description
Geometry	A sine star shape.

CreateSineStar()

Generates the geometry for the sine star

Declaration

public Geometry CreateSineStar()

Returns

Type	Description
Geometry	The geometry representing the sine star
