Méthode	Description
BezierCurveQuadric ( Vector2 startAnchor, Vector2 endAnchor, Vector2 controlPoint )	Constructs a new BezierCurveQuadric.
BezierCurveQuadric ( float parallel, Vector2 startAnchor, Vector2 endAnchor, Vector2 controlPoint )	Constructs a new BezierCurveQuadric.
CalculateLength ( float precision ) : float	Calculates the length of this bezier curve. The precision gets better when the precision value gets smaller.
CalculatePoint ( float t ) : Vector2	Calculates the point with the specified t.

Method Details

BezierCurveQuadric() public méthode

Constructs a new BezierCurveQuadric.

public BezierCurveQuadric ( Vector2 startAnchor, Vector2 endAnchor, Vector2 controlPoint )
startAnchor	Vector2	The start anchor.
endAnchor	Vector2	The end anchor.
controlPoint	Vector2	The control point.

BezierCurveQuadric() public méthode

Constructs a new BezierCurveQuadric.

public BezierCurveQuadric ( float parallel, Vector2 startAnchor, Vector2 endAnchor, Vector2 controlPoint )
parallel	float	The parallel value.
startAnchor	Vector2	The start anchor.
endAnchor	Vector2	The end anchor.
controlPoint	Vector2	The control point.

CalculateLength() public méthode

Calculates the length of this bezier curve.

The precision gets better when the precision value gets smaller.

public CalculateLength ( float precision ) : float
precision	float	The precision.
Résultat	float

CalculatePoint() public méthode

Calculates the point with the specified t.

public CalculatePoint ( float t ) : Vector2
t	float	The t value, between 0.0f and 1.0f.
Résultat	Vector2

Property Details

ControlPoint public_oe property

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

public Vector2 ControlPoint
Résultat	Vector2

EndAnchor public_oe property

End anchor point.

public Vector2 EndAnchor
Résultat	Vector2

Parallel public_oe property

The parallel value.

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 public_oe property

Start anchor point.

public Vector2 StartAnchor
Résultat	Vector2
