There is a LIC parameter that is responsible of the "heavy" feature when
you pan, rotate, zoom, etc..
Look at the bottom of the "Display" tab of your object that use LIC: you
will see the option "Use LIC when using LOD". This option is checked by
default and makes LIC to recompute the rendering while your are moving
the object.
Uncheck this option: LIC will be deactivated while you are changing the
view and it will render the object only when you will release the mouse
button. It may take a while before rendering occurs after mouse button
release depending on a parameter in the settings: menu "Edit->Settings",
select "Render View" and look at the value of the "Lock interactive
render" parameter: it should be 2 (seconds) by default and you may set
it to zero.
@David:
I think the surface vectors and surface flows filters are meant to
address this problem.
I have tested these filters together with the "Stream tracer with Custom
source" filter, but I never succeeded in getting full streamlines on the
curved surface of an aircraft. I think there is really a problem of
projection in the Stream Tracer algorithm. I wonder if this projection
is done as it is only a second order modification of the vector
direction and it is not needed to follow a stream line in volume.

Thank you Richard.
The LIC seems heavy when you pan, zoom in or zoom out your geometry, not in
generating the flow paths. What you get is actually really nice.
If there no way in getting good streamlines (as you pointed out I got short
lines only) then the LIC is fine.
Maybe there's a way of generating that directly in openfoam, as there is for
free flow streamlines.
Thank you again for your time.
