[Paraview] FW: Surface-constrained Streamtraces

[Bastil2001 at yahoo.de]

1. why not use VTK_Edge? What is the drawback?
2. we do:
a. create vector from shear stress components (calculator)
b. Extract the part of multiblock-dataset we want to but streamlines on
c. mask points, random, draw
d. StreamTracerWithCustomSource, Fluid as an Input and mask points as an
source, selecting the created shear stress vector field.

This works quite good but sometimes streamlines break at the border of a
block. However I was considering VTKEdge recently. Is it bad?
