      • CubicSplineInterpolatorVector3D_fPtr

        public CubicSplineInterpolatorVector3D_fPtr​(long cPtr,
                                                    boolean cMemoryOwn)
      • CubicSplineInterpolatorVector3D_fPtr

        public CubicSplineInterpolatorVector3D_fPtr()
        Default constructor yielding a NULL-pointer.
      • CubicSplineInterpolatorVector3D_fPtr

        public CubicSplineInterpolatorVector3D_fPtr​(CubicSplineInterpolatorVector3D_f ptr)
        Do not take ownership of ptr.

        ptr can be null.

        The constructor is implicit on purpose.
    • Method Detail

      • delete

        public void delete()
      • isShared

        public boolean isShared()
        check if this Ptr has shared ownership or none
        ownership
        Returns:
        true if Ptr has shared ownership, false if it has no ownership.
      • isNull

        public boolean isNull()
        checks if the pointer is null
        Returns:
        Returns true if the pointer is null
      • x

        public Vector3Df x​(double t)


        Note: The cubic polynomial is given by a 3-degree polynomial:
        \bf{f}(t)= \bf{a} + \bf{b}\cdot t + \bf{c}\cdot t^2 \bf{d}\cdot t^3
      • dx

        public Vector3Df dx​(double t)


        Note: The derivative is a 2-degree polynomial:
        \bf{df}(t)= \bf{b} + 2\cdot \bf{c}\cdot t + 3\cdot \bf{d}\cdot t^2
      • ddx

        public Vector3Df ddx​(double t)


        Note: The second derivative is a 1-degree polynomial:
        \bf{df}(t)= 2\cdot \bf{c} + 6\cdot \bf{d}\cdot t
      • duration

        public double duration()
