[IGSTK-Users] Coronal and Sagittal Views

[Patrick Cheng]

Hi Ashwath,

CameraPosition is only one part of the puzzle. To get the view right, 
you also need to consider a range of parameters. Here are the three 
important ones:

   /** Set Camera position */
   void SetCameraPosition( double x, double y, double z);

   /** Set camera focal point */
   void SetCameraFocalPoint( double x, double y, double z);

   /** Set Camera View Up vector */
   void SetCameraViewUp( double vx, double vy, double vz);

In your case, you just moved the camera, but still looking at the old 
spot (FocalPoint), you need to do a parallel shift of the FocalPoint as 
well to achieve your desired result.
