Class PoStreamLineMotion

  • All Implemented Interfaces:

    public class PoStreamLineMotion
    extends PoStreamParticleMotion
    Representation of streamlines with motion of colors. Class to visualize streamlines on a mesh, with a motion of color on the lines that simulates a animation of particles. Each line is drawn with only 2 colors : lineColor is the background color of the streamline, and particleColor is the color of some parts of the line that move during visualization. The field PoMesh.coloringType and PoMesh.valuesIndex are not used by this class.
