Here's the some fun code to check out. You set up a 3d scene, then pull out your glasses and watch as it comes out of the screen. Still need to make it so that you can put it in a game rather than just make one still shot at a time...but it's still cool anyways.
If you don't have 3D glasses, get a red gel sheet (thin plastic sheets used for coloring lights on stages and such) and put it over your left eye, then get an aqua (blue/green) colored gel sheet and put it over your other eye. Enjoy!
(if anyone can make this into a shader or usable in a game, let us know)

That's because shutter glasses work on a totally different theory.

Joe's effect is overlapped images, shutter glasses work on alternating frames.

The way it works is that you take two camera shots of a scene (one for each eye). you then combine the red values of one with the blue and green values of the other. The glasses will then neutralize the places matching the colors over each eye, so each eye recieves a different image (like in real life). The only reason we see depth is because we have two eyes.

i used to draw pics as a kid with red and blue and use the 3d glasses that came with comics.

thicko, if you're redoing it for shutter glasses, it will be simpler. You don't need to mess with the colours, just the offset of the alternating images.

How do you plan to do it? I would think just shifting the camera each frame would be enough.

@thiko: That wasn't so much to you as to anyone might want to now how it works so that they could try doing it.

So how do shutter glasses work? I might be able to come up with something.

shutter glasses work with 2 images. they open and close ove each eye rapidly alternating so with one eye you see one image and the other eye sees the other image producing what i think is a very high quality 3d image.
they work with all direct x apps so even your basic cube spinning can be shown in 3d very easily,i use them for games but they unfotunatly dont work properly with doom3.
just make a program using 3d commands and the glasses do the rest of the work, their very good and were quite cheap too.

That's why I have the red-cyan scheme for 3d. With that, you can obtain the glasses in all sorts of way, or just make your own. Not as good quality, but still fun to see.

I understand that they are expensive, but why would you still buy them anyway?

you cant make lcd digital shutter glasses unless your an electronics wiz and then you have to write the drivers for them and
because they enhance games, im currently playing theif 3 and they improve the game with more depth perception, the images really appear to come out or go deep into the monitor,i was dubuios when i bought them but now i use them on all games ( some games dont work properly with them).

OK, whatever. It just seems strange that someone would spend that much money on 3d glasses.

that much? clearly youve never tried them.i got a geforce 5500,2 gig of ram and a 2800 athlon mobile,i use my machine for writing programs and playing games,most people spend at least £30 on a game that might last about 2 weeks before theyve finished with it, ive had the glasses 6 months and im still using them and they really enhance a game.
as for " ok wahtever it seems strange" no...it isnt strange , its my preference and i bet poeple including yourself have spent more on somthing that you maybe have only used once or twice.
why bother having a 3d card in the machine...becuase you want to experince better graphics,you want to see the depth, the glasses add to that experience.

Could it work in real time if you use the set camera to image command?

Nice

I did this, well a long time ago (2003 I think it was). Just used some camera rendering to sprites which had selective colour channels
