There is a shot in 300 that I would like to try and replicate:

A short explanation of how they achieved this shot can be found in the April issue of American Cinematographer. Basically they mounted 3 high speed Arri film cameras onto one head, each camera with a different lens (wide, medium, and close). One camera was mounted normally, i.e. horizontally, and the other two were mounted vertically and pointed directly down into a prism or beam splitter, so all the cameras appeared to have the exact same camera angle. In post, they switched between the cameras at certain points using a synthetic morph/zoom.
My question is: how did they use the prism to align the cameras, and where can I learn more about this technology?
And what morph effect/plug-in was used in post to switch between the shots?
Thanks in advance
