[Paraview] VTK_Edge for LIC

[Adriano Gagliardi]

Zhanping,
 
Will the options to modify the density, thickness, and colour of the
streaklines be available to the user? It is definitely a good tool, but
sometimes we find it better to visualise using the standard streamtracer as
we can modify their appearance for clarity.
 
-Bastil: If you use extract surface, you'll need to make sure you have a
shear stress vector available on the surface (or create one before-hand),
assuming you are doing aero flows. However, if you use extract block on the
surfaces within the ensight volume data, you should be able to use the
velocity vector as input for LIC too (I think it takes the data just off the
surface for visualising, although I'm not sure). It isn't as nice as using
shear stress, but works well enough.
 
Regards,
 
Adriano

In fact we are now integrating LIC to VTK. One of the features is that flow
streaks are clearer than before in the resulting image.

Dear group,

I have compiled VTK_Edge against paraview 3.6.2. Everything worked fine
except that make install did not install "libVTKEdge.so" to the install
directory - I had to copy this manually. Is this a bug or a feature?

Afterwards I can load libVTKEdge.so to paraview without problems.
However, where are the new features? I am especially interested in LIC
and I only found lic on 2D structured grids and LIC on image data in the
filters menu. Both are greyed off with my Ensight-Reader multiblock
unstructured grids. Does it only run on structured grid? Am I missing
something?
