Public Methods

Method Description
BezierCurveCubic ( Vector2 startAnchor, Vector2 endAnchor, Vector2 firstControlPoint, Vector2 secondControlPoint )

Constructs a new BezierCurveCubic.
BezierCurveCubic ( float parallel, Vector2 startAnchor, Vector2 endAnchor, Vector2 firstControlPoint, Vector2 secondControlPoint )

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 ) : Vector2

Calculates the point with the specified t.

Private Methods

Method Description
CalculatePointOfDerivative ( float t ) : 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 ( Vector2 startAnchor, Vector2 endAnchor, Vector2 firstControlPoint, Vector2 secondControlPoint )
startAnchor Vector2 The start anchor point.
endAnchor Vector2 The end anchor point.
firstControlPoint Vector2 The first control point.
secondControlPoint Vector2 The second control point.

BezierCurveCubic() public method

Constructs a new BezierCurveCubic.
public BezierCurveCubic ( float parallel, Vector2 startAnchor, Vector2 endAnchor, Vector2 firstControlPoint, Vector2 secondControlPoint )
parallel float The parallel value.
startAnchor Vector2 The start anchor point.
endAnchor Vector2 The end anchor point.
firstControlPoint Vector2 The first control point.
secondControlPoint Vector2 The second control point.

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 ) : Vector2
t float The t value, between 0.0f and 1.0f.
return Vector2

Property Details

EndAnchor public property

End anchor point.
public Vector2 EndAnchor
return Vector2

FirstControlPoint public property

First control point, controls the direction of the curve start.
public Vector2 FirstControlPoint
return Vector2

Parallel public 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 property

Second control point, controls the direction of the curve end.
public Vector2 SecondControlPoint
return Vector2

StartAnchor public property

Start anchor point.
public Vector2 StartAnchor
return Vector2
