Class PoStreamTadpoleMotion

  • All Implemented Interfaces:

    public class PoStreamTadpoleMotion
    extends PoStreamParticleMotion
    Animation of tadpole particles along streamline. Class to visualize particle along streamlines on a mesh. Each particle is represented by a line set which looks like a tadpole.

    Each particle is represented by a segment made up of 3 aligned points. The segment's length is equal to lengthFactor*V, where V is the velocity interpolated at the position of the particle. Each segment has a width attribute equal width.

    The 2 end points of each segment is colored by backColor. If PoMesh.coloringType != COLOR_INHERITED and if PoMesh.valuesIndex is defined (i.e. >=0) the middle point is colored in applying the current data mapping to the scalar value interpolated at the particle position. If PoMesh.valuesIndex is undefined (i.e. <0) the middle point is colored in applying the current data mapping to the velocity interpolated at the position of the particle. Otherwise (PoMesh.coloringType = COLOR_INHERITED), if PoBaseStreamLine.colors is not empty, the middle point is colored by one of these colors (all the particle of the same streamline have the same color), or by particleColor if PoBaseStreamLine.colors is empty.
