    Modifier and Type
    Method
    Description
    double
    arcLength(double positionA, double positionB)
    Gets the result of ∫ab|f'(t)| dt.
    That means it calculates the arc length (in meters) between positionA and positionB.
    Vector3
    get1stDerivative(double position)
    Gets the result of f'(position).
    Vector3
    getPosition(double position)
    Gets the result of f(position).
    int
    getSegment(double position)
    Get the segment position.
    void
    setNodes(List<Node> nodes)
    Sets nodes to be used by subsequent calls to getPosition(double) and the other methods.
