I tried your skript for 2.49
Basically it is great, also your page is awesome holds lot of useful information.
I used your script some time ago, sadly it didn´t satisfy my needs.
Its static, not working for animations, I can´t change the zeroplane via animation.
Also I sometimes got objects too close, so divergent looking would be needed, so I would need to get the zeroplane near in the animation and thus lessen the eye seperation.
Also linking the cameras is not what I like in animated scenes, I like them in one scene and then render one eye with the farm, check the animation for glitches, then render the other eye.
not output them via compositor which is not working with e.g. loki and rendering L/R each pass to find out I can redo it because of a glitch
Another problem is, if you got vast exterior scenes and you got to shrink your scene by 0.1 to avoid zbuffer issues it gets messy with the shiftX (i know its the approximated version, but satisfyable) the values get too small =)
Maybe you´d like to adapt it to a camera constraint =) Thats what I was working on but I had to stop due to a lack of time =(
Great would be a constraint similar to the track to constraint on a center camera, which controls the 2 stero cams, aiming at an empty representing the zeroplane.
You can select an intended default eye seperation (i mostly use 6.5cm) and the shiftX gets calculated based on the distance of the target object. so you can animate the targetobject and the shift gets adapted accordingly, and if the zeroplane gets too near, the eye seperation lessens to ensure convergent looking.
At least thats the idea.
Another question. Do you know anything about “ghostbusting”?
I ran in the problem that I barely found any papers or informations on how to do it. And with Cineplexx Digital Cinemas its a huge problem… the good cinema projectors automatically adapt the images to prevent ghosting between the stereo images… The Digital servers in the Cineplexx cinemas all over europe use another tech and don´t have it.
And yes, there is a stereo 3D spot running in the constantine film group cinemas, that was actually done with Blender, at least in Austria =) As you are from Germany, you might have seen it too on Pro7.

I just wonder how long it is until they finally proof that stereo 3D is rather unhealthy… =)
Still, all my nagging aside, for stills your skript is the best there is unless you want to get your calculator out
