3D House of Felines

[tugrik]

Today was spent tooling around the Big Basin redwoods and checking out Revar's recently-acquired sub-micro pocketcam. It's got a little helper app built in for taking 3D stereo pictures. You take the "left eye" shot, and then it split-screens to show you the image you took with a superimposed grid. Move a few inches to the right in a properly parallel way, use the grid to keep everything level and centered and *snap*... stereogram. The camera comes with a little plastic viewer thingy even. Print out a 4x6 of the picture, set the viewer on the center and if you did everything right, you get a 3D picture. While not as easy to view as a lenticular print the results are far superior.

Revs let me take a pic or two with it. The one of Leo, one of the two Cats of Los Gatos (Leo and Leona, they're quite a pair), came out best.

Here's the cross-eye version
and Here's the straight L/R pair version..

To see it in 3D, view the cross-eye version and cross your eyes until the two images form one image in the center. Hold that for a minute and your brain will figure it out and start processing depth information. Some folks are better at letting their eyes drift to parallel (move outwards instead of inwards); they should view the straight version. Of course, if you've got a printer and a simple stereo viewer that's the best solution, if a bit more effort-requiring.

Of all my LJ friends I figured Lynx would like this pic the most. :)

That is just -so- cool! I've always been able to cross my eyes and make them do funky things (dance, baby! Dance!) but this is the first time it's come in real useful.

I have got to get me one of those.

I can NEVER do things like that. My eyes are just too boring, I suppose.

My eyes are crossed so I don't see the 3d stuff well, alas. ;)

Crossing my eyes got me three of them.

Correct. Concentrate on the one in the middle. :)

Hmmmm.

I have _so_ got to try making an animated .gif with a stereo pair of animations };>.

Might do that now, for bonus procrastination points =o.o=. But it would look cooler with a real object.

Done, and stayed up about three hours longer than I should have doing it (5 hours longer than I *really* should have).

I'd forgotten just how crappy my old drawing algorithm is. In principle it's more flexible, but in practice by overhauling it to do ray-tracing instead of brute-forcing I'd get a factor of a thousand speed increase. The problematic figures can fall back to the old algorithm (or use a smarter successive approximation method), if I support them at all.

Bedtime. I estimate falling asleep just shy of 5am.

No matter how much i try I never seem to be able to work that 3D effect stuff.

Wow. That's really spiffy, Tugs. More pictures! ;)

[goldwing.livejournal.com]

Oh, wow!! It works! That's so cool.

Haven't gotten the 3-d effect, but I LOVE the statue!!
