Hi,

I'm got an upcoming stereo 3D project which will involve compositing li= ve action footage with graphics generated within AE. =A0There's a small= team of people doing various tests now and one thing they're looking a= t is whether to shoot and comp with parallel cameras or converging cameras.=
I've worked in stereo 3D a little and have only used parallel cameras -= the 3D book by Bernard Mendiburu suggests that parallel cameras should alw= ays be used when comping live action with CGI.

So for the stereo 3D gurus out there - is there any reason or benefit to us= ing converging cameras? =A0Or ar e we wasting our time even considering the= option?

-Chris
