Do not set the OuterPosition, but the Position:
set(gca,'Position', [0 0 1 1]);
Setting the OuterPosition considers space for the TickMarks, Labels and the Title.
Objects on the front dissappear, when they are moved behind the camera position. Then changing the CameraViewAngle instead of the CamaraPosition is helpful. In both cases the zooming effect is similar (not identical), but the view-angle does not change the distance between the view point and the oobjects.
