maybe if so i can try to implement my self the window-portal vr effect

In should be possible, since you can smoothly zoom in and out...

Since when??? :? I think you are confusing zoom (change of "field of view") with "getting closer" (change of position).

And smooth zoom does not recreate the effect you are trying to achieve, if that is still the Wii video of Johnny Chung Lee.
