    public class PoCurveLine
    extends PoChart
    Class to build a 2D line curve. Builds a 2D curve line on 1D mesh (PoIrregularMesh1D or PoRegularMesh1D). The abscissas of the curve 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 line is specified by the field thicknessIndex which is an index of a value-set of the current mesh 1D. If thicknessIndex == -1, the thickness of the curve is inherited. This class also takes into account of the current mesh 1D hints (PoMesh1DHints). The interpretation of colorBinding is the following :

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

      colorValuesIndex 1

    • Field Detail

      • thicknessIndex

        public final SoSFInt32 thicknessIndex
        Defines the index of the set of values used to specify the thickness. If thicknessIndex = -1, all the curve has the same thickness which is the inherited line width.
      • thicknessBinding

        public final SoSFEnum<PoCurveLine.ThicknessBindings> thicknessBinding
        Defines how thickness values are bound to the curve. If thicknessBinding = PER_PART_THICKNESS, each part of the curve has the same thickness otherwise the thickness between two consecutive vertices is linearly interpolated according to the thickness value associated to these vertices. For curve line, PER_VERTEX_THICKNESS is interpreted as PER_PART_THICKNESS.
      • thicknessFactor

        public final SoSFFloat thicknessFactor
        Defines a multiplicative factor applied to the thickness values.
