[Paraview] How to use paraview to mark something on the object

[Tianshi SUN]

Hi all,

I am new for paraview, and thank in advance for all kinds of help.
My question : I am doing the visualization of a wheel rotating on the road,
and want to do some marks (e.g line..) on the wheel. The marks can move
with the wheel together, so that we can see the wheel is rotating but not
just slithering on the road. Also the color of the wheel is changing for
each time step, because the displacement is also changing in X,Y and Z
directions, but the marks should have a fixed color, which can make it
obvious to be observed. I do not know how to do it. Please help me.

Regards.
