Is there any proper way (API) to implement 3D? I'm not talking about rendering.

I know the perspecta 3d people have there own little very-much-like-opengl api for their 3d projector. I have never touched it so I don't know too much about it.

I don't have a 3D TV, and won't likely have one in the next few years, so I don't know. But from what I see it seems some TVs decode the 3D from a standard 2D interlaced image (left odd lines, right even lines, or vice versa), loosing vertical resolution, or side by side, loosing horizontal resolution.

of course this technique also works quite well ;)

this screen seems to be a nice to have one ... http://www.vancouversun.com/Vancouver+company+puts+depth/3055750/story.html

Anyone recalls shark jumping out of an ad screen in 'back to the future' ? sounds like a fulfilling prophecy.

not really. you're still far away from that.

xemobyl: "fulfilling" :) give it time, you'll see it for yourself.

Is there any known way to project a true volume image yet? As in a true, open air, no-tricks-with-mirrors-or-poisonous-gas 3d image.

No, I think the gas-holograms are the current best bets. Everything else only works for either one person, or requires glasses (or contact lenses).

I think the sentence "3d will always be the future" was already used in the early 80s.

fuck 3d. i have a lazy eye and none of that perspective shit works for me.

xteraco - orthographic vision. Awesome.

have anyone tried to display anything from PC to 3D projector or two projectors? I know that there's sth like quad buffer for Quadro's also there's IZ3d which I didn't try - but are there any other solutions? the projector takes 2 HD-SDI's. On the other hand we already did it on 3d tv and it rulez :). Completely new quality.

There's also this project: http://www.holografika.com/

bonzaj: I don't know, but it shouldn't be different from using opengl on 2 different monitors.

4D ist he future.

Currently 3D = 2D * 2.

and once again, the danes are lightyears ahead.

Danmarks største kran!

det så jeg også heine :)

kralalalalaaan!

Should both cameras be parallel, or should they intersect at a point?

bonzaj - yea, I've done an implementation to two projectors. Other than quadbuffer, you can just output to two windows on the two outputs. The biggest issue is getting vsync to happen at the same time for both outputs :p Which works on quadro's, and not necessarily on mainstream cards.

depends on what you're doing. If they both point at a fixed position, that position is the screen itself when you view the image later (i.e. anything behind that point is behind the screen etc)

If they're parallel everything is behind the screen I think.

Pity there's nothing promising for true 3d yet. We need to remove the screen completely, and project directly into space. Nearest thing so far is VR.. this way you can have many people viewing in full 3d, but it's still just stereo and involves glasses (in this case even bigger + heavier + more intrusive!)

I really hope to see a full immersive 3d environment without glasses + crap before I die :)

That sounds too esoteric. How would you send realtime data too it? Only if it was something fake like parallax mapping using the zbuffer...
