For a while now, the term used to refer to "no-glasses" 3D has been the word autostereoscopic or auto-stereoscopic. Since stereo refers to only 2-views, the words automultiscopic and auto-n-view-scopic seem more appropriate now since we are usually dealing with 5 to 9 views, and the term is catching on in the industry.
Here's some webpages which use the new term "automultiscopic":

Converting Stereo 3D to MultiView (N-view) 3D
In the world of autostereoscopic video production, you will often be presented with a client that has 3D footage already shot (in the can) and they want it converted to MultiView (N-View) 3D, for example, 8-view 3D, so that they can display it on an autostereoscopic monitor.
This is not a simple or cheap task, but there are options available to make it happen.
A popular camera often used for stereo-3D rigs is the RED ONE Camera.
3D Film Factory sells rigs for the Red ONE; you can see the 3D-BS (Beamsplitter) here.
They also have a side-by-side rig, the 3D-SS, viewable here.
The end result is that you get a RED Cinema Camera File (*.r3d) which contains a stereo pair of videos, e.g., you get 2 pictures for each frame of video. Each picture is at a slight horizontal offset, so that you get disparity which lets you extrapolate a 3D image.
Now what?
Now you let the professionals do their magic with your 2-pics-per-frame-stereo-3D, and you get back an 8-pics-per-frame video, ready for your autostereoscopic display.
I know of two ways to get the conversion done. The first is a company located in Florida named 3D Eye Solutions. I haven't viewed any of their work personally, but I have a friend who has and he says they do good work.
The second option, if you're familiar with 3D International's z.l.i.c.e.3d software, is to buy their new plug-in, Stereo Tools, and let it do the magic for you. I haven't seen their work either, but I am a user of z.l.i.c.e.3d and I can affirm to it's wonderfullness.
Hope this helps.
