Animated Stereogram

[Grafixman]

Mike, you got a point here. I can't make out what it is. The moving pattern is too distracting. Maybe it's because of the jerky nature of gif animation, specially for relatively large pictures? Flash gives smoother transition. But compensating for the moving pattern could be a harder challenge. Random dots could be the only way to display such things. Now we just need somebody to come up with a way to extract the depth image from two cameras and create live motion animated stereographs. Then we'd all go blind trying to watch a movie made entirely with it. http://www.talkgraphics.com/images/smilies/biggrin.gif

Grafixman,
it's actually Gary's 3D cube from his tutorial, and I agree it's hard to see it properly. It was originally 1.4Meg, I had to cut the image size and reduce the frame count, before I could post it, and I'd be much happier if the background textures would stay put, too. That's why I wasn't in any rush to post it, but it makes the point well enough. Egg's approach is much the better one.

An alternative is to have two separate left and right images side by side, and use the crossed-eyes technique to view them, and I have played with Xara3D for this, a little, again with no notable success, yet. Might play a bit more, though, now.

Mike,

Way cool! A stereogram on a windy day! http://www.talkgraphics.com/images/smilies/smile.gif

I didn't have any trouble seeing it, but it took a few seconds to tease out the rotating shape from the textures.

Well done!

Cool stuff.

Egg - You could create your Flash fish as simple vector objects and using the spacing technique create a very small file. The background bitmap image is probably adding to the file size.

Mike- Your animation looks as if the forest is closing in on me http://www.talkgraphics.com/images/smilies/eek.gif

I'm thinking of starting off February with a new stereogram tutorial. One of the batch I just finished for the Japanese is called Miss Piggy and has some good moves and would make a good tutorial (IMHO).

OK, let's see how this goes. I'm not entirely sure the result is true 3D, but it seems OK. Crossed-eyes technique to view, ie look at one engine, then cross the eyes. That will cause images to move towards each other. When they properly overlap, the middle one will hopefully be in 3D.

Alright I am the first to admit it I have tried and tried to go cross eyed but I still only see the foreground.

Here is a simple device I made with
4 mirrors to view stereopairs.

Well, it seems Xara3D is well suited to experimenting with this type of 3D imaging. I ran up two instances of Xara3D, side by side, loaded up the same animation file, and started tweaking them together, while (and I know this is going to sound utterly stupid!) looking cross-eyed at the screen. With a little practice, I can adjust the viewing angles while watching in stereoscopic 3D to get the best effect in real time!

It also occurred to me that a textured background might help set the 3D scene, so I added a texture, and adjusted its x-offset to get it at the best depth. Then I exported the two animations and brought them into XaraX1 to pair the frames up, and re-exported as a single animation.

I also added the two white blobs to help with the viewing. If you can manage to view it, it seems to work pretty well.

Egg I can't see your image I can't open the link you gave.... http://www.talkgraphics.com/images/smilies/frown.gif

P.S. Access what is that thing for? What are stereopairs?

Mike - If you modifiy the rotation of the image on the right, rotate it away about 5 degrees, you should get a real 3D effect.
