[vtkusers] Standard Views

[Jeff Lee]

Hi Ted,
Something like

    given xv, yv, zv, (camera position)
    given nx, ny, nz (camera viewup)

    vtkCamera cam1 = ren.GetActiveCamera();
    cam1.SetFocalPoint(0,0,0);
    cam1.SetPosition(xv, yv, zv);
    cam1.ComputeViewPlaneNormal();
    cam1.SetViewUp(nx, ny, nz);
    cam1.OrthogonalizeViewUp();

    so your application just has to provide the camera viewup vector and 
the camera position...

-Jeff
