Member Function Documentation

float OpenTK.BezierCurveCubic.CalculateLength

(

float

precision

)

Calculates the length of this bezier curve.

Parameters

precision

The precision.

Returns

Length of the curve.

The precision gets better when the precision value gets smaller.

Vector2 OpenTK.BezierCurveCubic.CalculatePoint

(

float

t

)

Calculates the point with the specified t.

Parameters

t	The t value, between 0.0f and 1.0f.

Returns

Resulting point.

Member Data Documentation

Vector2 OpenTK.BezierCurveCubic.EndAnchor

End anchor point.

Vector2 OpenTK.BezierCurveCubic.FirstControlPoint

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

float OpenTK.BezierCurveCubic.Parallel

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.

Vector2 OpenTK.BezierCurveCubic.SecondControlPoint

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

Vector2 OpenTK.BezierCurveCubic.StartAnchor

Start anchor point.
