Syntax

[Serializable]
public struct BezierCurve

Constructors

BezierCurve(params Vector2[])

Initializes a new instance of the BezierCurve struct.

Declaration

public BezierCurve(params Vector2[] points)

Parameters

Type	Name	Description
Vector2[]	points	The points.

BezierCurve(IEnumerable<Vector2>)

Initializes a new instance of the BezierCurve struct.

Declaration

public BezierCurve(IEnumerable<Vector2> points)

Parameters

Type	Name	Description
IEnumerable<Vector2>	points	The points.

BezierCurve(float, params Vector2[])

Initializes a new instance of the BezierCurve struct.

Declaration

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

Parameters

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

BezierCurve(float, IEnumerable<Vector2>)

Initializes a new instance of the BezierCurve struct.

Declaration

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

Parameters

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

Fields

Parallel

The parallel value.

Declaration

public float Parallel

Field Value

Type	Description
float

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 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>, float, float)

Calculates the length of the specified bezier curve.

Declaration

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

Parameters

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

Returns

Type	Description
float	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(IList<Vector2>, float)

Declaration

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

Parameters

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

Returns

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

CalculateLength(float)

Calculates the length of this bezier curve.

Declaration

[Pure]
public float CalculateLength(float precision)

Parameters

Type	Name	Description
float	precision	The precision.

Returns

Type	Description
float	Length of curve.

Remarks

The precision gets better as the precision value gets smaller.

CalculatePoint(IList<Vector2>, float, float)
