Hi All,

I am wondering if it is possible to do collision detection between two scalar bar actors. I saw [this](https://discourse.vtk.org/t/find-the-actor-that-another-actor-is-intersecting-with/1379/2) thread that mentioned CollisionDetectionFilter. I saw that the filter works with Polydata.

Is there a way to do collision detection of Actors?
