new to vtk/render a prism(wall) that vibrates along time

Hello! I’m new to vtk. I already rendered in .vtk a group of particles (vtkunstructuredgrid) in movement (+1000) with scalars (temperature, radius…) to view in paraview, I had previously all conditions of particles generated by a fortran code. Besides that, now I’m litlle bit confused in how to render a wall/prism that vibrates(68hz) with only the initial conditions (coordinates of structure, repose, v=0). I was reading the vtk user guide witch inspired me to use vtkpolydata, but to create a animation I would need to repeat that several times, someone has a better method and could help me?
Also, it’s planned to integrate this vibrating wall to the animation of the particles above-mentioned.
Thanks for your help!
