This style shows a deficiency of PTE, that some French experts (including JPD) already mentioned a couple of years ago. In PTE, all 3D-objects are rendered using a fixed eye point (observation point), about 342% in front of the screen. It would be fine if PTE would offer slide options for changing the position of the slide's eye point.
