[Paraview] Your thred on Kitware forum about particle tracing

[Dan Lipsa]

Hi Jagan,
Sorry for my delayed reply - I have been in vacation last week.

This shows why it is a good idea to send questions to the ParaView list
rather than individual developers. This way, you'll probably get answers
quicker.

1. You probably seeded your streamlines in areas where vector values are
very small. Try increasing Streamline Parameters / Maximum Steps and / or
Maximum Streamline Length.

You can also try changing the Line Parameters and moving the seeding line
to a different area of your dataset.

2.
There are standard vector measures computed:
AngularVelocity
Rotation
Vorticity
and additional arrays that provide more information about the process:
IntegrationTime
ReasonForTermination
SeedIds

The documentation for the class used is at:
http://www.vtk.org/doc/nightly/html/classvtkStreamTracer.html
