[vtkusers] Camera alignment

[Rodolfo Palacios]

Hello.

I'm working on an application for medical images visualization. I need to 
display the three common views of medical 3d imaging: axial, coronal and 
sagittal. My problem is that I can't seem to find an effective way to align 
each camera to display the images correctly.  (I'm using 
vtkImagePlaneWidgets).

One way I've been trying to do this is this one, but doesn't work very well, 
I don't know why.

vtkXWindowCamera->SetFocalPoint(0,(bounds[3]/2),bounds[5]/2));               
  vtkXWindowCamera->SetPosition((bounds[1]),(bounds[3]/2),(bounds[5]/2));
vtkXWindowCamera->ComputeViewPlaneNormal();
vtkXWindowCamera->SetViewUp(0, 0, 1);
vtkXWindowCamera->OrthogonalizeViewUp();
vtkXWindow->GetRenderer()->SetActiveCamera(vtkXWindowCamera);
vtkXWindow->GetRenderer()->ResetCamera(bounds);
vtkXWindow->GetRenderer()->ResetCameraClippingRange();

Thank you.
