Is there a way to catch such mouse events for `GeometryModel3D` objects? I tried handling the `MouseEnter` and `MouseLeave` events on a `PointGeometryModel3D` geometry but was never called.

Most of the visuals in Helix Toolkit derives from `ModelVisual3D`, so mouse events are not enabled. The `ViewCube3D` is an exception. Search for `UIElement3D` in the solution to see usages. For hit testing, see the `Viewport3DHelper` extension methods - `FindHits` etc."}}
