Right now MITK supports the Connexion Mouse just under Windows. A support for Linux and Mac is still missing.
Imo there are two possible ways:
- use the vtkTDx classes
(http://www.itk.org/Wiki/VTK/3DConnexion_Devices_Support)
- use the 3d Connexion SDK
(http://www.3dconnexion.com/service/sdk/licence-agreement/sdk-download.html)
and modify the SpaceNavigator driver class to work under linux/mac.
Since the vtkTDx classes only focus on using the spacenavigator in a render window, I suggest to write something compatible to the windows driver class.
