Class PoPointsFieldBars

  • All Implemented Interfaces:

    public class PoPointsFieldBars
    extends PoGraphMaster
    Class to build a points field bars. Class to build parallelepipeds based on a point field. This class generates a set of parallelepipeds where the bases are on the plane XY and the heights are given by the altitude for each point on the point field. The parallelepipeds are colored as a function of values for each point.

    Colors of the bars depend on the current data mapping. If the method setDataMapping(dataMapping) is called, the current data mapping is "dataMapping". Otherwise the current data mapping is specified in the current inherited state (cf property node PoDataMapping and its derived classes). If there is no current data-mapping (i.e setDataMapping() not called and no PoDataMapping node traversed before in the scene graph), all bars get the same color which is the inherited color.

    • Field Detail

      • point

        public final SoMFVec3f point
        List of points for parallelepipeds. point[i][2] is the altitude of the i-th parallelepiped.
      • value

        public final SoMFFloat value
        Values for each point. If value.getNum() != point.getNum(), the parallelepipeds have all the same color, that is the inherited color.
      • width

        public final SoSFFloat width
        Width of parallelepipeds.
      • height

        public final SoSFFloat height
        Height of parallelepipeds.
    • Constructor Detail

      • PoPointsFieldBars

        public PoPointsFieldBars()
        Default constructor.
      • PoPointsFieldBars

        public PoPointsFieldBars​(SbVec3f[] _point,
                                 float[] _value,
                                 float _width,
                                 float _height)
    • Method Detail

      • getDataMapping

        public PbDataMapping getDataMapping()
        Gets a reference to a PbDataMapping object to the association color-value.
      • setDataMapping

        public void setDataMapping​(PbDataMapping dataMapping)
        Sets a reference to a PbDataMapping object to the association color-value. If this method is not called (or called passing NULL as argument), this is the data mapping defined in the current inherited state (defined with the property node PoDataMapping and its derived classes) which is used.
