Class CubicSplineType


  • public class CubicSplineType
    extends AbstractCurveSegmentType
    Cubic splines are similar to line strings in that they are a sequence of segments each with its own defining function. A cubic spline uses the control points and a set of derivative parameters to define a piecewise 3rd degree polynomial interpolation. Unlike line-strings, the parameterization by arc length is not necessarily still a polynomial. The function describing the curve must be C2, that is, have a continuous 1st and 2nd derivative at all points, and pass through the controlPoints in the order given. Between the control points, the curve segment is defined by a cubic polynomial. At each control point, the polynomial changes in such a manner that the 1st and 2nd derivative vectors are the same from either side. The control parameters record must contain vectorAtStart, and vectorAtEnd which are the unit tangent vectors at controlPoint[1] and controlPoint[n] where n = controlPoint.count. Note: only the direction of the vectors is relevant, not their length.

    • Method Detail

      • getPosOrPointPropertyOrPointRep

        public List<javax.xml.bind.JAXBElement<?>> getPosOrPointPropertyOrPointRep()
        Gets the value of the posOrPointPropertyOrPointRep property.

        This accessor method returns a reference to the live list, not a snapshot. Therefore any modification you make to the returned list will be present inside the JAXB object. This is why there is not a set method for the posOrPointPropertyOrPointRep property.

        For example, to add a new item, do as follows:

            getPosOrPointPropertyOrPointRep().add(newItem);
         

        Objects of the following type(s) are allowed in the list Pos PointRep PointProperty

      • getPosList

        public PosList getPosList()
        Gets the value of the posList property.
        Returns:
        possible object is PosList
      • setPosList

        public void setPosList​(PosList value)
