Hello

I would like to make a 3d animation without using anaglyph.  This means that I need a right and left eye render.  Does anybody know how to do this?  Do I render and then render again by moving the camera to the right or left?

Please advise and thank you.

 I just did a magazine article about this. 

You can set up multiple cameras together into a rig and do multiple renders specifying each different camera for the renders, combining them in post production. I'm not aware of a software (besides some previz plug-ins for Maya) that allow simultaneous renders from two cameras.

However, unless you have access to Real D polarization processing, you'll still need to post process into anaglyph.

Thank you.  Can you direct me to the magazine article or be a little more specific about the multiple cameras and renders.  Also what are the previz plugins for Maya that allow the simultaneous renders from two cameras?

Thank you very much.

 Hi Jack, 

The magazine is just finishing production: Issue 2 of 3D Artist (http://www.3Dartistonline.com) It should be out in about 3 weeks in the UK - I don't know about the US markets.

Historically, a plug-in was needed. However the new release of Maya (as previewed at SIGGRAPH) has significantly improved stereoscopic capabilities built in but requires using e-Dimension LCD shutter glasses for realtime on-screen proofing to catch trouble spots.

Mark is the pro here, but I'll put in 2 cents...

I think the basics could be done within Carrara like this:

1. Create two conical cameras with same settings a reasonable eye width apart.
2. Make a target helper object. (Name it something like "stereo rig".)
3. Make the two cameras a child of that target helper.
4. Make another target helper. (Name it something like "focus target".)
5. Set both of the cameras to track the focus target.

Now you should be able to set where the "body" is and where the "eyes" are looking by doing those steps. (I suspect you may want to experiment to see if the results are better or worse with or without a focus target, keeping both cameras straight may give a more infinite field.) You'll have to render the entire animation separately for each camera though. (Switcing between the two cameras positioned this way should be easier than trying to offset a single camera to achieve the same effect.) Figuring out how to use both animations at once will be interesting. I think the same rendering process would be fun for stills if there were a way to get the images into something like an ol' school Viewmaster.  

Thank you for your help.
