Class PoRibbon

  • All Implemented Interfaces:

    public class PoRibbon
    extends PoCurveLine
    Class to build a 2D ribbon curve. Builds a 2D ribbon curve on 1D mesh (PoIrregularMesh1D or PoRegularMesh1D). The abscissas of the ribbon are given by the geometry of the current mesh 1D, and the ordinates are given by one of the value-set of the current mesh 1D specified by the field yValuesIndex. The thickness of the ribbon is specified by the field thicknessIndex which is an index of a value-set of the current mesh 1D. These values are multiplied by the field width. If thicknessIndex == -1, the thickness of the ribbon is the value of the field width. This class also takes into account of the current mesh 1D hints (PoMesh1DHints).

    The interpretation of colorBinding is the following :

    • INHERITED: The entire ribbon is colored with the same inherited color.
    • PER_PART : Each part of the ribbon is colored with the same color. A part is the ribbon between two abscissas defined by the current mesh 1D.
    • PER_VERTEX: A color is used at each vertex of the ribbon.

    File format/default:

    PoRibbon {

      colorBinding INHERITED
      yValuesIndex 0
      colorValuesIndex 1
      material NULL
      thicknessIndex -1
      thicknessBinding PER_VERTEX_THICKNESS
      thicknessFactor 1.0
      width 1.0

      • width

        public final SoSFFloat width
        Defines the width of the ribbon. If the thicknessIndex is different from -1, thickness values are multiplied to this value.
