Method	Description
BezierCurve ( ) : System	Constructs a new BezierCurve.
BezierCurve ( IEnumerable points ) : System	Constructs a new BezierCurve.
BezierCurve ( float parallel ) : System	Constructs a new BezierCurve.
BezierCurve ( float parallel, IEnumerable points ) : System	Constructs a new BezierCurve.
CalculateLength ( IList points, float precision ) : float	Calculates the length of the specified bezier curve.
CalculateLength ( IList points, float precision, float parallel ) : float	Calculates the length of the specified bezier curve. 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 ( float precision ) : float	Calculates the length of this bezier curve. The precision gets better as the precision value gets smaller.
CalculatePoint ( IList points, float t ) : System.Vector2	Calculates the point on the given bezier curve with the specified t parameter.
CalculatePoint ( IList points, float t, float parallel ) : System.Vector2	Calculates the point on the given bezier curve with the specified t parameter. 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.
CalculatePoint ( float t ) : System.Vector2	Calculates the point with the specified t.

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 5.0f to the orignal curve at any point.
