Public Methods

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

Private Methods

Method	Description
CalculatePointOfDerivative ( float t ) : System.Vector2	Calculates the point with the specified t of the derivative of this function.

Method Details

BezierCurveCubic() public method

Constructs a new BezierCurveCubic.

public BezierCurveCubic ( System.Vector2 startAnchor, System.Vector2 endAnchor, System.Vector2 firstControlPoint, System.Vector2 secondControlPoint ) : System
startAnchor	System.Vector2	The start anchor point.
endAnchor	System.Vector2	The end anchor point.
firstControlPoint	System.Vector2	The first control point.
secondControlPoint	System.Vector2	The second control point.
return	System

BezierCurveCubic() public method

Constructs a new BezierCurveCubic.

public BezierCurveCubic ( float parallel, System.Vector2 startAnchor, System.Vector2 endAnchor, System.Vector2 firstControlPoint, System.Vector2 secondControlPoint ) : System
parallel	float	The parallel value.
startAnchor	System.Vector2	The start anchor point.
endAnchor	System.Vector2	The end anchor point.
firstControlPoint	System.Vector2	The first control point.
secondControlPoint	System.Vector2	The second control point.
return	System

CalculateLength() public method

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.
return	float

CalculatePoint() public method

Calculates the point with the specified t.

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

Property Details

EndAnchor public_oe property

End anchor point.

public Vector2,System EndAnchor
return	System.Vector2

FirstControlPoint public_oe property

First control point, controls the direction of the curve start.

public Vector2,System FirstControlPoint
return	System.Vector2

Parallel public_oe property

Gets or sets 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.

public float Parallel
return	float

SecondControlPoint public_oe property

Second control point, controls the direction of the curve end.

public Vector2,System SecondControlPoint
return	System.Vector2

StartAnchor public_oe property

Start anchor point.

public Vector2,System StartAnchor
return	System.Vector2
