An interesting problem :-) Does the topology of the mesh change over time or just the positions of the points? Essentially, we need a landmark that moves with the wheel to which we can attach something. If the topology does not change, you can start by selecting one of more cells, extracting the selection and then coloring those cells a solid color (you might need to translate them slightly to avoid rendering artifacts). If that works, you could use the Python Programmable filter to create a line that starts at the centroid of the extracted cell. If you want to do that, let us know and someone on this list can help you with the appropriate VTK API.
