    Types

    type Curve

    type Curve []point

      Curve implements Bezier curve calculation according to the algorithm of Robert D. Miller.

      Graphics Gems 5, 'Quick and Simple Bézier Curve Drawing', pages 206-209.

      func New

      func New(cp ...vg.Point) Curve

        NewCurve returns a Curve initialized with the control points in cp.

        func (Curve) Curve

        func (c Curve) Curve(p []vg.Point) []vg.Point

          Curve returns a slice of vg.Point, p, filled with points along the Bézier curve described by c. If the length of p is less than 2, the curve points are undefined. The length of p is not altered by the call.

          func (Curve) Point

          func (c Curve) Point(t float64) vg.Point

            Point returns the point at t along the curve, where 0 ≤ t ≤ 1.
