[Paraview] Visualizing rotating sphere

[William Oquendo]

Dear all,

I apologize in advance if this is an extremely simple question for you but I
have not been able to find solution to the following: I am simulating a
system of spheres interacting with each other. I am printing their
information into a vtk-xml file as points with both scalar (mass, radius,
number of contacts, etc) and vectorial (Position, Velocity, etc) attributes.
I am using the sphere glyph to visualize the actual sphere, scaling
them appropriately by radius. At the end of each simulation I have a time
series described into a .pvd file which names and associate time to the
individual vtk-xml file. The previous allows me to make animations of my
system (one of the several ways to go, o course). I am representing the
glyph as a Surface with Edges, in order to track rotations.

What I want to know is how can I represent my spheres correctly into
paraview in order to show clearly their rotation. Let's assume the following
simple example. The vertical axis is z. The particle is rotating with
angular velocity along that axis. If I orient the glyph using the angular
velocity, the glyph will orient along the z axis but then it wont rotate. I
am very likely forgetting something useful in Paraview for this problem, so
I really would like to know your suggestions.

Thanks in advance.

Best regards / Cordialmente,
