Hubble In Anaglyph Stereo 3D
rwllama writes "We at the Hubble Space Telescope have quietly released our first anaglyph (i.e. red/cyan) stereo 3D movie of a flight into a Hubble image. This work is a follow-on to the sequences we produced for the 'Hubble 3D' Imax film. Note that the 3D interpretation uses lots of artistic license, so it is not intended to be scientifically accurate. We would love to hear the Slashdot crowd's feedback on whether you want more, are artistic interpretations of scientific data acceptable, is anaglyph 3D too annoying, how many could watch this with a real 3D (e.g., NVIDIA 3D Vision) setup, etc?"
First new word I leaned today: Anaglyph
The 3D YouTube player allows the user to decide if they want to watch a 2D version, a cyan/red version, a real 3D version (i.e. shutter glasses), etc.
It looks like it could be neat, but without the glasses, it's just a red/blue mess.
From TFA:
"Q: I am color blind. Can I see the stereo 3-D movies?
A: Unfortunately, no. The anaglyph stereo 3-D technique relies on colors to separate the left and right eye images. If one can not see or distinguish between certain colors, then the anaglyph stereo 3-D effect will not work."
That's incorrect. The color of the image and the color of the lens is used to direct a false colored monochrome image to each eye. That is, the left eye receives a blue tinted monochrome image and the right eye receives a red tinted monochrome image (or vice-versa).
For someone who is color blind and can't differentiate red and blue, then they will perceive the color arriving at each eye to be the same. For them, the 3D effect will be even better.
I can't think of a way to release something to the tech world more quietly than a post to Slashdot. (No, I'm not serious)

I don't care if it's made to be poop color...there are never enough images from the Hubble. Anything they are willing to present is good in my book!

The only way to show the vastness of space is to have its focus at infinity. If you exaggerate the human interocular distance by a billion to show the Carina Nebula "in 3D", all you're doing is making the Carina Nebula look a few dozen feet wide. When will people learn? I'm still puking from having seen a round Earth in Resident Evil Afterlife.
If I want artistic freedom, I can watch video games or movies (where lots of hubble images end up anyway). So the more scientifically correct you can get, the better. Using non natural colors is OK, but even then it would be good if every movie / image would identify which colors are original and what is artistic freedom. I suspect a large number of people believe that many artistically colored images show normal spectrum images. -Bernd

I fail to see how being unable to distinguish between colors has any effect on a filter placed in front of your eyes... By the time your eyes see the image it's basically monochrome.
09F91102 no, 455FE104 nope, F190A1E8 uh-uh, 7A5F8A09 that's not it, C87294CE no. Ah! 452F6E403CDF10714E41DFAA257D313F.
Darn, you beat me to it! Mod points and a beer for you!
Given that, outside the solar system, there's hardly anything closer than a couple parsecs except for some very faint objects, and 1 parsec is 1 parallax *second* (as in, 1/3600th of a degree), and it represents the angle formed by watching the same object from 2 observation points spaced 1AU (or 2AU?) apart, does this allow any actual 3d effect to be perceived by the brain? The left/right image separation should be insufficient (unless of course the content has been heavily software processed).
Also, please, don't release anaglyphs, there's a lot of different video hardware to enable 3d vision. Just release video with the left/right frames (side-by-side, above/below, alternating, you choose) and let each of us view it optimally on our hardware. There's plenty of software to accomplish that, even java applets and browser plugins.
Vacuum cleaners suck. Kings rule.
Cool! But parallel viewing works just fine, too. How 'bout a version in that?
Don't tell me that I'm the only one who has anaglyph glasses within arm's reach of the computer. Anyway, this video's not that great of an effect. It's kind of disappointing.
so it's obviously a work of fiction/misinformation/take your eye off the billionerrors 'ball'.
Ouch - this is the best that Hubble can do? The images show serious chromatic aberrations, with significant red-blue fringing on edges. What's worse is that the effect gets more pronounced as the camera moves around. They should really consider ditching the point-and-shoot and movie up to an SLR with a decent carl-zeiss lens if they want to be taken seriously.

Depth perception is what space images lack. We have colors, movement, but no depth.
I've anaglyph lenses. It seems your visualization is a simulated stereo taken from one image instead of two eyes, because all the layers look flat, like images in cards. I hope with time you develop a better simulation technique to increase the immersion.
Why are "you at the Hubble Space Telescope" wasting your time asking slashdot users what they want? Don't you have better things to do?
... and then they built the supercollider.
I fail to see how [...]
Then you're probably colorblind.
If you design the experience properly you don't have to choose between an artistic and scientifically accurate rendering of the Hubble material. You can first show the artistic version and then add a scientific overlay with a basic set of data (what you're looking at, distance from earth, chemical makeup, etc). You can then transition into the wonky scientific version for a final pan across the subject matter so that you're representing the needs of multiple viewers. A decent 3D Info-graphics template can look really cool and add some production value without breaking your budget as well.
If I someone at Hubble was actually interested I'd be willing to donate some time in making a storyboard that illustrates the concept.

We would love to hear the Slashdot crowd feedback on whether you want more, are artistic interpretations of scientific data acceptable
To be honest, I always have that "why? Isn't it impressive enough as it is?" when artistic interpretations are applied to astronomy. Whenever I'm shown amazing pictures of galaxies and gigantic colored gas clouds, and I go all "Whoa, so cool!", I die a little inside when I scroll down to the small text mentioning artistic interpretation.
I suspect the known universe has plenty of beautiful sights as it is, and every time astronomy-sites feel the need to involve artistic interpretations, I'm left wondering if the universe is in fact not at all as beautiful as I want it to be, or if it's just that all our technology isn't adequate to actually produce a decent image.
Artistic interpretations makes it feel like astronomers need to tell us a lie to keep us interested.
If you are funded by the US government, then I would say no, don't waste any more of your time our our money on this. If you are privately funded, then sure, go ahead.
In theory, it should make no difference. In practice, if the brain of a color blind individual perceives one image as being brighter than the other, it won't be able to combine the images.
but somehow it failed miserably and I didn't see anything. I used these. What am I doing wrong ?
PS should I perhaps print them on glossy paper ?

As this small picture will show you , being color blind don't mean you see the color as *black* wiki color blind of american flag each type of our color detector cells see actually a wide spectrum, and it overlaps. So depending on the "red" used in those lens for glasses, you will see gray stuff, or even green stuff if the absorption is not a pure red line.
where can i see this and where can i get some acid?
Give me good old side-by-side parallel viewing any way. Requires a bit of effort to focus the right way, but once you've got the trick it's pretty easy to even play games this way. I remember an old Quake1 patch for that. Made the game feel a lot more real and yet easier to play. The sense of depth helped a lot.
I am color blind, lacking the ability to see red light. The red-cyan glasses don't work for me because from my point of view the red lens is completely opaque (black) and the cyan lens completely translucent (clear). Thus, you could simulate my experience with the glasses by covering your left eye with your hand and watching the movie with your right eye only. It's not exactly an improvement ...

This was an interesting experiment! I've enjoyed looking at Mars rover anaglyphs, and I think it makes sense to visualize interstellar phenomena in 3D as well. I'm a big fan of anaglyphs, because they are easy to transmit and reproduce, even if the color reproduction is poor.
A problem I see with this clip is that there's much inconsistency as objects pass on to or off of the edges of the screen. When something passes off the edge, it disappears for 1 eye first, then the other eye. This is very distracting.
An Iranian stereoscopic photographer has come up with a "floating window" technique that can eliminate some of these distracting effects. More info is available here:

I enjoyed watching it, however I think you should offer a download of a true 3D format so I could use my 3D vision which gives a much more clear picture.

I have one of the new 3D TVs. Like Nvidia's real3D, my Samsung LED based LCD TV can view various 3d formats natively (off a USB drive, or streamed over a dlna device). Including "Side by Side" and "Top & Bottom". Other 3d formats can be viewed as outputted from a computer like interlaced (field sequential), Line by Line, Vertical Strip and Checkerboard. There isn't a lot of content available for these Televisions, so with the right marketing you'd get a lot of interest from owners.

When did the HST become a manned satellite?
Oh, come on, guys! That was just really poorly done. The whole idea of anaglyph is to try to make as much filtered out in each eye as possible. Obviously no one really looked at this or else they used something other than "normal" shades of red/cyan. Close the right eye and there is a ton of ghosting through the red filter.
I'm a big proponent of 3D, but only when it's done right. This was actually painful to look at.
The Overrated mod is for reversing inappropriate, positive mods, not for voicing disagreement with a post.
NASA should post the 3D stuff to Youtube with a 'yt3d' tag and let Youtube do all the work as far as 3D formatting. Anaglyph, SBS, Interleave and many others which will let you watch with pretty much any 3D displaying device, including modern 3DTV's
My son would love to connect up the Hubble Anaglyph with orbiter.org and blender.org simulations.
His generation is technically capable of using these simulations in interactive ways.
Can Hubble create tutorials for integrating these Anaglyph into processing.org, blender.org and orbiter.org?
My son (14) is now despondent over NASA cutbacks and the recent ISS work showing humans will die of AIDS like thymus failure in long space travel.
Mice thymus fails within 6 months in microgravity. Mice get colon cancer and coats turn grey.
Astronauts also show the loss of bone, muscle, and immune system consistent with mouse studies.
UofAz created microarray for thymus failure.

Is it true that you actually cannot detect red light at all? So a red filter, and even a room lit only by a red light bulb, look black to you? That would imply that your "red" and "green" cones are not merely mixed up, they are both completely broken (there's a lot of overlap), and that your rods (along with your "blue" cones) are also completely unable to sense 564nm light.
Reading further, it seems that rods are largely inactive in well-lit circumstances, so perhaps they are simply insufficient to detect enough light to balance the blue cones in your other eye. Interesting.
