Capturing video from two cams stimulatously and 3D display

[qualityinmind]

Hello everyone,

I have a little problem with my project. It is all about capturing video from two cameras which are close to each other and film one object from nearly the same angle. the result is something like this:



Switching between cams will add 3D effect. Do you have any ideas how to make this in directshow? Can you help me with this?

Thanks!

The "wiggle" effect, as it is known in many 3D circles, is a cute (and occasionally helpful) toy.

For those who don't have any Stereo3D display systems (including glasses), and who don't want to learn to manipulate their eyeballs (parallel or cross-eye), this is a quick way to give the "impression" of 3D even though it's still not Real 3D.

I say QUICK because it is not something ANYONE will want to look at for more than a few seconds (a few minutes, tops)! Otherwise, you're sure to cause headaches, and the Stereo3D world doesn't need any more of that - we're trying to combat that. I'm sure that, with your avatar, you'll agree.

So, while it's quite easy to do for still photos (Animated GIF or Flash), and I can think of a few ways it could be done with video, I'm not going to recommend them.

If you really want to do Stereo3D, I have plenty of tools, techniques and suggestions...

I know that this is "impression" of 3D, there are many methods better than this, but still, I want to try this. And I must. This is my school project, and it wasn't my idea in the first place. I wanted to do 3D display with glasses, but you know... Higher powers.
I'd be most grateful for ideas, tools or anything that can help me.

OK,

You want stills - use GIF Animator, put in just the 2 bitmaps each about 1/2 second long, and loop it. Save as animated GIF (understand that it will only be 256 colors).
Flash would be similar (You'd actually NEED Adobe Flash/Shockwave or similar to use the "stage" and timeline). Flash can be 24 bit color. DO NOT save as Flash Video - it should maintain its still source and play/generate at runtime.

For video, I'd use an AVISynth script. Load 2 "streams" of video and tell AVISynth to alternate every frame (or every other frame). Save as an .AVS and load that into Virtualdub and save as an AVI (use whatever codec you're most pleased with - Xvid is good).
Alternately, don't do any combining/mixing/editing. Just create videos of both views at a lower framerate (say - 7.5fps, 10fps or 15fps), load both views into Stereoscopic Player and tell it to output Pageflip mode.
There are other ways.

I strongly recommend that you learn the best ways of creating and showing stereo3d, and advocate (maybe even insist) those ways to your "higher powers".
