Hi everyone,<br><br>I had asked this a couple of days back and had been trying all kinds of things on my side, albeit unsuccessfully.<br><br>I have a 3d volume which passes through a reslicer and that gives me a 2d slice. Now, there are additional transforms that manipulate the slice (zooming, rotation etc).
<br><br>So, ultimately I have a vtkImageViewer like object that displays this slice. Now, I want to be able to get the image coordinates from the screen coordinates. I have been trying for days but no luck. I do not think there is a picker in vtk that will allow me to do that.
<br><br>Does anyone has any idea on how this can be achieved? I really need to get this working. Right now, I compensate for the zoom by just dividing by the zoom factor. However, as the number of transformations grow, this will get quite complicated for me to manage. It would be nice to see if VTK can do something.
<br><br>Most pickers give me the global coordinates as pick points. Is there any way to get the image coordinates from them?<br><br>Thanks,<br><br>Anja<br>
