Hi, Patrick,

I have a try and found if I changed both camera position and view up vector, the view can display the same as VolView. 
This is the change,

switch( m_Orientation )
    {
    case Sagittal:
      {
      position[0] += distanceToFocalPoint;
      m_Camera->SetViewUp (     0,  0,  1 );
      break;
      }
    case Coronal:
      {
      position[1] -= distanceToFocalPoint;
      m_Camera->SetViewUp (     0,  0,  1 );
      break;
      }
    case Axial:
      {
      position[2] -= distanceToFocalPoint;
      m_Camera->SetViewUp (     0,  -1,  0 );
      break;
      }
    }


Thanks a lot!
