Hey Phil, why don’t you call James Cameron and tell him to stop calling it Avatar 3d LOL! (And technically stereo is 2 angles.) Oh and @ the person who’s going to call in the Feds if they can’t get 2D TV LOLOLOLOLOLOL!!!!!!!!!! Wow lots of funny ones here.

Hey Phil:

These are not 3D. They are *stereo*. Big difference. If they were 3D, you could observe the subject matter from more than one angle. Stereo images are still one angle, just like a 2D image. This is the same technology the Viewmaster was using in the 1950′s, and others even before that. Let’s not get ahead of ourselves here. If for no other reason than when you see a *real* 3D display, you won’t have anything left to call it.

I see a runner being tagged at second base on the piece on the left – and from the positions of the runner and the second baseman, the runner was attempting to steal third.

I just remembered that I have an old copy of 3-D Star Maps on my bookshelves, which came with two anaglyph specs tucked inside.

I prefer the crossed eye type 3d photos. The only equipment required is two working eyes. No further monetary expenditures necessary.

You can get blue/red glasses with the DVD of “Fly Me To The Moon” too – a kids’ movie about Apollo 11.

Glad everyone’s liking the pics on my blog – thanks for the plug, Phil! Anyone wanting cheap 3D glasses: go into your local discount bookstore and take a look at the kids section, where you’ll find at least one kids “3D Book Of Dinosaurs!” or “…Bugs!” that comes with one or more sets of 3D glasses.

Gary, You can get 3D glasses here. I got the $6.95 Pro-V view ones and they work just dandy. I tried the Avatar glasses at first too. Nope. [I thought a $15 ticket warranted keeping the glasses and I assume the distributors can afford it!]

I’ve never heard of anyone being able to “learn” to see 3-d images w/o glasses however, as anecdotal as your question is, it might be a place to begin some investigation. Perhaps you have differential spectrum sensitivity in each eye, ie, one eye is more sensitive to blue, while the other is more sensitive to red.

Just a thought.

Thanks. Didn’t realize my glasses were just polarized lenses.

Zucchi: I don’t have stereoscopic vision either, and images like these just give me a headache. I can avoid going to see 3D films, but if regular TV shows start getting broadcast in 3D only, I’m calling in the disability laws on them.
Yes, I’ve wondered a few times what true stereosccopic vision is like. All I have a a kind of faux-stereoscopy, where my brain compares objects by distance. That way, I can look at distant things like mountains and think “Hey! is that what depth looks like?”

Doesn’t anyone else see the stickman drawing on the rock on the right? He’s holding something in his left hand! Absolute proof of intellient aliens visiting our solar system. QED!!! Wait til I tell Dick Hoagland about this!

What? No, I don’t know what pareidolia means but I know I won’t get the vaccine for it!

Hey Phil, question, since I know how much you love optical illusionary-type stuff and what tricks the brain can play on us: having looked at lots of anaglyphs over the years (just because they’re so darned cool), when I see an anaglyph displayed now, I almost feel like I can partially see it in 3D without even wearing glasses.

Is it possible that the brain can somehow adapt to separating out the tints by itself, giving a pseudo-3D view even without glasses? Or have I just seen enough 3D images of regolith on Mars to know what it *should* look like? Or am I just plain broken?

Now we need to add a stereo tag: “I didn’t do it…it was broken when I got here.”

I can tell you this much: at the movies it’s way overrated.

I always feel envious about this stuff. I don’t have stereoscopic vision in normal life, so stereo pictures and movies don’t work for me. I wonder what it’s like.

FYI, about 15 minutes ago there were two very bright orange lights in the sky over the south of the Netherlands. The lights were somewhat flickering and moved in north-south direction. There was quite some distance between them. I kept watching but there were no sounds of airplanes. Eventually the lights faded just like I’ve seen before with (other) meteors.

Tree Lobsters is on the right track here for me; I’m still hatin’ on these multicolored 3-D images. I never have acquired the right glasses for these & much prefer the “Crossed-eye” technique, although that’s another kettle of fish. Plus, post – “Avatar,” half of the world probably has the polarized 3-D glasses that they kept as a souvenir, and this may be a format to begin to post such images. Not that I want to start a new format war here, or anything – Betamax 3-D, anyone?
At any rate, thanks for posting these in whatever format available.

Here’s a little Mars/3-D history factoid. The movie The Man From Mars was shot and presented in 3-D way back in 1922. The process had two separate projectors synced to show the left-right frames alternately: left-right-left-right, and so on. Each audience member then had a 3-D viewer attached to the chair. The viewer had left-right eye shutters that opened & closed alternately in sync with the frames up on the screen. It was somewhat like shoving your face into that tester an the eye doctor. The system was so easy and comfortable to use that it’s been in dignified retirement for close to 90 years.

I first read “anaglyphs” as “analglyphs” and was a little afraid to click on the link. Boy was I wrong.

The Avatar specs separate the images with polaroid filters. Anaglyphs separate them with the colored tints. Since computer monitors can’t differently polarize the images, the only option (using specs) for 3-D on your browser is anaglyph.
