I've gotten close. What I do is use my pan method that I wrote which pans by using vtkCamera.Position and vtkCamera.FocalPoint on the mouse, and then I zoom in/out at the same time. That seems to work for me.<br><br>

Hi,<div><br></div><div>I amb also interested in a zoom-to-point behaviour. Have you achieved what you were looking for, Jonathan? What has been your approach?</div><div><br></div><div>I'm just playing with vtkRenderWindowInteractor::FlyToImage() but it's not enough for me by now. It would be great if you can share your improvements with the community ;)<div>

I have applied the vtkInteractorStyleImage to the image, and I can zoom using the right mouse button. However, this always zooms in on the center of the image.
