public struct BezierCurveQuadric

Constructors

BezierCurveQuadric(Vector2, Vector2, Vector2)

Initializes a new instance of the BezierCurveQuadric struct.

Declaration

public BezierCurveQuadric(Vector2 startAnchor, Vector2 endAnchor, Vector2 controlPoint)

Parameters

Type	Name	Description
Vector2	startAnchor	The start anchor.
Vector2	endAnchor	The end anchor.
Vector2	controlPoint	The control point.

BezierCurveQuadric(float, Vector2, Vector2, Vector2)

Initializes a new instance of the BezierCurveQuadric struct.

Declaration

public BezierCurveQuadric(float parallel, Vector2 startAnchor, Vector2 endAnchor, Vector2 controlPoint)

Parameters

Type	Name	Description
float	parallel	The parallel value.
Vector2	startAnchor	The start anchor.
Vector2	endAnchor	The end anchor.
Vector2	controlPoint	The control point.

Fields

ControlPoint

Control point, controls the direction of both endings of the curve.

Declaration

public Vector2 ControlPoint

Field Value

Type	Description
Vector2

EndAnchor

End anchor point.

Declaration

public Vector2 EndAnchor

Field Value

Type	Description
Vector2

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.f to the orignal curve at any point.

StartAnchor

Start anchor point.

Declaration

public Vector2 StartAnchor

Field Value

Type	Description
Vector2

Methods

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 when the precision value gets smaller.

CalculatePoint(float)

Calculates the point with the specified t.

Declaration

[Pure]
public Vector2 CalculatePoint(float t)

Parameters

Type	Name	Description
float	t	The t value, between 0.0f and 1.0f.

Returns

Type	Description
Vector2	Resulting point.
