Did you watched vtkInteractorStyleTrackballActor ? <br><br>This class enables rotations for each actor in your renderer. When you point the camera on one actor (A), you can use the trackball on actor A. If you point your camera on a second actor (B), you can use the trackball on actor B,...etc.<br>
<br>Anyway, if this solution isn't well for you, you can create your own interactor style class. I made that a short time ago. <br>You have to subclass a vtkInteractorSlyle class ("vtkInteractorStyle" being the basic class). But it can become a little bit complicated.<br>

Oh, many thanks for this pdf! It may be usefull to me.<br>
<br>
What I was searching is for a class (interactor) that automatically set focal point on center of actor, and then mouse events pivot or move camera around that focal point or actor, I think that vtkInteractorStyleTrackballCamera don't has this features.<br>
<br>
The only way I can do is manually on my own class?<br>
Many thanks.<br>
