public class PoBaseStreamLine extends PoMesh
The streamlines are calculated from a set of vectors in the current mesh. See PoMesh for more explanations about the current mesh. The index of vectors data set used to compute streamlines, is defined by the field PoMesh.vecsIndex. If this vectors data set does not exist in the current mesh, the representation is empty. The origin of each vector is a node of the mesh.
The derived classes respect the following rules to color the representation:
If PoMesh.coloringType = COLOR_INHERITED and if the field "colors" is empty, the representation uses only one inherited color, so each part of the representation have the same color.
If PoMesh.coloringType = COLOR_INHERITED and if the field colors is not empty, the representation uses each colors of field for each streamline. For example, the streamline starting from the i-th startPoints is colored by colors[inum_colors], where num_colors is the size of the field "colors".
If the field PoMesh.valuesIndex is not defined (i.e. < 0), and if coloringType != COLOR_INHERITED, the representations are colored by using the current data mapping applied to the velocity at each point of the streamlines. The definition of the "current data mapping" is explained in PoMesh.
If the field PoMesh.valuesIndex is defined, and if coloringType != COLOR_INHERITED, the representations are colored by using the current data mapping applied to the value at each point of the streamlines.
