    • Field Detail

      • BSpline

        public static final long BSpline
        B-Spline basis. Each curve segment must have 3 or 4 control points. Curve segments join with C^(N - 2) continuity, where N is the number of control points. The curve does not necessarily pass through the control points without additional control points at the beginning and end of the curve. Each curve segment can overlap N-1 control points. API-Since: 17.0

      • CatmullRom

        public static final long CatmullRom
        Catmull-Rom basis. Curves represented in this basis can also be easily converted to and from the Bézier basis. Each curve segment must have 4 control points. Each index in the control point index buffer points to the first of 4 consecutive control points in the control point buffer. The tangent at each control point is given by (P_(i+1) - P_(i-1)) / 2. Therefore, the curve does not pass through the first and last control point of each connected sequence of curve segments. Instead, the first and last control point are used to control the tangent vector at the beginning and end of the curve. Curve segments join with C^1 continuity and the curve passes through the control points. Each curve segment can overlap 3 control points. API-Since: 17.0

      • Linear

        public static final long Linear
        Linear basis. The curve is made of a sequence of connected line segments each with 2 control points. API-Since: 17.0
