[IGSTK-Users] Re: Problems visualizing Differents DICOM sets

[Patrick Cheng]

Hi Manuel,

I have tried your code, and the problem is:
For View2D, you need to specify a viewing orientation so that it will 
know what to put the camera.

After Line 99 in your viewerGUI.cxx code, you need add a line like:
   Display->RequestSetOrientation( igstk::View2D::Axial);

Also notice that, it's better to call
   Display->RequestResetCamera();
After
   Display->RequestAddObject( representation );

The way VTK reset camera works is, it put the camera in a proper 
position that will accommodate all actors in the scene. So you have add 
the representation to the Display first, and then call RequestResetCamera.

so from the line 99, you code should look like:

   Display->RequestSetOrientation( igstk::View2D::Axial);
   Display->RequestEnableInteractions();
   Display->RequestAddObject( representation );
   Display->RequestResetCamera();
   Display->Update();

This should solve your problem.
