[Paraview] animating a vrml mesh

[Johannes Eckstein]

Hi there, I am currently visualizing Particle data as an unstructured 
grid in paraview, using a .pvd file that collects all the .vtu files 
together.
I now have the problem that I want to visualize a mesh e.g. a .vrml 
file, and animate it, meaning I would like to update its position and 
orientation with every time step from the corresponding .vtu file.
I did not find a paraview forum so I am hoping someone here is willing 
to give me some hint on how to do this. Or I would have to program my 
own source or use the programmable sources or filters.
when I simply open the .wrl file I get in the info tab:
Multi-block Dataset
0: Polygonal Mesh
Only in the "Display" tab I can change the position of the Mesh or add a 
transformation filter, but either way I would have to enter the position 
for each timestep. Now I think there must be a better way to do that and 
someone here knows the answer already?
