3d Imagery

[silvio]

Does anybody know how to make 3d visuals, not like 3Ds, but the kind that pop out of the screen. I know I saw a post on this but just can't seem to find it.

Another is, has anyone try this on a LED screen?

Cheers

There are a few ways to display 3D.
The oldest, best known and most limited way is using red/green glasses. Limited since you can't show colors. But it works on a normal screen and probably also on a LED wall, although the limited resolution won't do wonders for the perceived depth.

One step up is using polarized glasses, works like red/green method but in full color. This requires 2 projectors (one for each eye) that project on the same surface.

A new screen, developed by Philips, allows images to leap out of the screen, without needing glasses to view the effect, using a lenticular lens in front of the plasma panel. This has a much more dramatic 3D effect then both of the 'glasses' techniques, but is limited in size to that of a plasma screen.

I've done 3D VJ sets on both polarized stereo and 3D plasma screens, and I'm about to announce a special version of Flowmotion that can drive both these systems (it can do red/green to but why would you)

Don't know if it's any use but I've had loads of fun with 3d shadows. Just use one red, one green light source an eyes width apart to cast shadow of an object onto a tranlucent screen. Look at the shadow from the other side of screen with red/green glasses - 3D. I did it live with kids throwing balls towards the lights - used to be big finish in music halls. The balls fly out toward the audience. Still works fine if you film it and project it back. Plus a well produced 3D shadow is a really spooky thing - scared the hell out of busload of 5-8 year olds when we used it as part of shadow play - they are used to their shadows staying behind the screen and actually ran away screaming when the "magic" shadow appeared.

ChromaDepth glasses are cool because there is no distortion when they are taken off. It uses a prism etched plastic lens that pushes the color RED to the outside (so it appears closer) and the color BLUE to the inside (so it appears farther away). Fairly convincing and used on some kids tv shows. Excellent for VJs because it looks best with bold graphics on black background and creating the depth layers is as easy as selecting colors.

Still looks "clean" without the glasses:
