public struct BezierCurve

Constructors

BezierCurve(Vector2[])

Constructs a new BezierCurve.

Declaration

public BezierCurve(params Vector2[] points)

Parameters

Type	Name	Description
Vector2[]	points	The points.

BezierCurve(IEnumerable<Vector2>)

Constructs a new BezierCurve.

Declaration

public BezierCurve(IEnumerable<Vector2> points)

Parameters

Type	Name	Description
IEnumerable<Vector2>	points	The points.

BezierCurve(Single, Vector2[])

Constructs a new BezierCurve.

Declaration

public BezierCurve(float parallel, params Vector2[] points)

Parameters

Type	Name	Description
Single	parallel	The parallel value.
Vector2[]	points	The points.

BezierCurve(Single, IEnumerable<Vector2>)

Constructs a new BezierCurve.

Declaration

public BezierCurve(float parallel, IEnumerable<Vector2> points)

Parameters

Type	Name	Description
Single	parallel	The parallel value.
IEnumerable<Vector2>	points	The points.

Fields

Parallel

The parallel value.

Declaration

public float Parallel

Field Value

Type	Description
Single

Remarks

This value defines whether the curve should be calculated as a parallel curve to the original bezier curve. A value of 0.0f represents the original curve, 5.0f i.e. stands for a curve that has always a distance of 5.0f to the orignal curve at any point.

Properties

Points

Gets the points of this curve.

Declaration

public readonly IList<Vector2> Points { get; }

Property Value

Type	Description
IList<Vector2>

Remarks

The first point and the last points represent the anchor points.

Methods

CalculateLength(IList<Vector2>, Single)

Calculates the length of the specified bezier curve.

Declaration

public static float CalculateLength(IList<Vector2> points, float precision)

Parameters

Type	Name	Description
IList<Vector2>	points	The points.
Single	precision	The precision value.

Returns

Type	Description
Single	The precision gets better as the precision value gets smaller.

CalculateLength(IList<Vector2>, Single, Single)

Calculates the length of the specified bezier curve.

Declaration

public static float CalculateLength(IList<Vector2> points, float precision, float parallel)

Parameters

Type	Name	Description
IList<Vector2>	points	The points.
Single	precision	The precision value.
Single	parallel	The parallel value.

Returns

Type	Description
Single	Length of curve.

Remarks

The precision gets better as the precision value gets smaller.

The parallel parameter defines whether the curve should be calculated as a parallel curve to the original bezier curve. A value of 0.0f represents the original curve, 5.0f represents a curve that has always a distance of 5.0f to the orignal curve.

CalculateLength(Single)

Calculates the length of this bezier curve.

Declaration

public float CalculateLength(float precision)

Parameters

Type	Name	Description
Single	precision	The precision.

Returns

Type	Description
Single	Length of curve.

Remarks

The precision gets better as the precision value gets smaller.

CalculatePoint(IList<Vector2>, Single)

Calculates the point on the given bezier curve with the specified t parameter.

Declaration

public static Vector2 CalculatePoint(IList<Vector2> points, float t)

Parameters

Type	Name	Description
IList<Vector2>	points	The points.
Single	t	The t parameter, a value between 0.0f and 1.0f.

Returns

Type	Description
Vector2	Resulting point.

CalculatePoint(IList<Vector2>, Single, Single)

Calculates the point on the given bezier curve with the specified t parameter.

Declaration

public static Vector2 CalculatePoint(IList<Vector2> points, float t, float parallel)

Parameters

Type	Name	Description
IList<Vector2>	points	The points.
Single	t	The t parameter, a value between 0.0f and 1.0f.

Vector2	Resulting point.

Remarks

The parallel parameter defines whether the curve should be calculated as a parallel curve to the original bezier curve. A value of 0.0f represents the original curve, 5.0f represents a curve that has always a distance of 5.0f to the orignal curve.

CalculatePoint(Single)

Calculates the point with the specified t.

Declaration

public Vector2 CalculatePoint(float t)

Parameters

Type	Name	Description
