<br>
Last time you sent me this example to change the location of a 3D point. In<br>
this example, I cannot rotate, translate the image through mouse event. Only<br>
thing that I can do is to drag the point to a new position. I found that<br>
using vtkInteractorStyleTrackballActor does not allow the default vtk<br>
interaction. So I changed it into vtkInteractorStyleTrackballCamera which<br>
allows the default vtk interaction. However, error occurred when I debugged<br>
the code. The error comes from " this->InteractionProp = this->MoveActor;":<br>
the InteractionProp is not a member of vtkInteractorStyleTrackballCamera.<br>
<br>
So what should I do to not only change the point location, but also rotate,<br>
translate, and zoom in/out the image?<br>
<br>
Thanks,<br>
