This to my knowledge turns out to be untrue. The current crop of 
mainstay 3D modeling software used in television and film (Wavefront, 
SoftImage, etc) does not merely "shade and color," but models true 
special relationships in the proper perspective, and thus is more than 
capable of rendering "true" stereo. The modeler or artist simply 
"cha-chas" the camera POV to whatever the desired stereo base is, and 
rerendering the scene(s) for the other "eyeball."

Of course, left and right would then need to be married to the 
appropriate format (field/frame sequential, polarized twin-film reels, 
etc) but the effect is all there...

You might be interested in searching the Photo 3D digests with regard to 
this topic, believe we've covered it in the past.
