Cinema4D has a programming language built in.  It is very similar to 
Java.  The pair of cameras use near and far points (as well as 
various camera parameters) to calculate the MAOFD-defined interaxial 
distances, based on the sacred writings of John Bercovitz.

If you don't make moving stereo pictures, you might not appreciate 
the ability to control the stereo window in real time.  As the camera 
moves around or zooms in, the optimal interaxial changes each second. 
While this can certainly be over-done, it's often better than either 
flat or unviewable video.

Other expressions change the size of the near plane, maintain the 
spatial relationships of all the camera components, etc.

If real videotape is desired, it can be downloaded directly to a 
digital camcorder over the firewire.  Since my computer can support 
much higher refresh rates than a television, I only dub to videotape 
for special projects.

Why do it?  There are many benefits of making up your own worlds, but 
I'll leave that for another message.  :^)
