// .NAME vtkTDxInteractorStyle - provide 3DConnexion device event-driven interface to the rendering window

// .SECTION Description
// vtkTDxInteractorStyle is an abstract class defining an event-driven
// interface to support 3DConnexion device events send by
// vtkRenderWindowInteractor.
// vtkRenderWindowInteractor forwards events in a platform independent form to
// vtkInteractorStyle which can then delegate some processing to
// vtkTDxInteractorStyle.

// vtkInteractorStyle vtkRenderWindowInteractor
