Well, if the images are displayed to each eye separately, on screens 
oriented to each eye, it would be best to render exactly what each eye 
would see. Two ordinary perspective cameras, rotated to focus on some 
point in the scene.

However, when viewing on screen, you are viewing two projections of the 
scene on a single flat surface. My results with parallel cameras have 
been very difficult to view, but translating and shearing the cameras by 
adjusting their directions seems to produce very good results.
