The Saturn Fly-By
Jamie noted that today's Astronomy Picture of the Day is actually a video of Saturn built by compiling actual photographs taken by Cassini in 2004. Unlike most videos of this type, this isn't actually 3D animation, these are the actual photos (albeit "digitally tweaked, cropped"). Great views of the planet, as well as Titan, Mimas and Enceladus.
I couldn't get the video to play at the link in TFA. But this one did: http://vimeo.com/11386048
Excuse me, I need to pick my jaw up off the floor.

It's a space station! Or was I the only one who noticed? @~1:34
It always surprises me how thin the ring is. BTW, Saturn, the Lord of the Ring? Saturday, I wonder if that had a special meaning to Tolkien. So, how is Peter's Hobbit going on? These movie delays always surprise me.
I'm not sure I understand what's happened here. It certainly looks like a computer animation!
Is each frame a separate photo? Just cropped to line up with the previous one, cleaned up and colour-treated to match?
Or is there a lot more artifice going on?
Great views of the planet, as well as Titan, Mimas and Enceladus.
Wonderful. Mama makes excellent titanic enchiladas.
And you are just some elitist fuckwit.
thats a fucking lie. that is computer animation, just with real still photos overlaid for the texture. you cant wave some still photos around like that and pretend its actual sequences of photos strung together in a film without people calling you out on your bullshit.
Anyone else see the death star at 01:33?
Right there at 1:30. No getting around it.
What do you mean they cut the power? How can they cut the power, man? They're animals!
by how beautiful that was.
slashdot: where everyone yells sarcastic metaphors to themselves to understand the issue
They didn't even get the disc in 3D while flying through them - this is AT BEST a 3D rendering with TEXTURES taken from the Cassini flyby - though frankly its so bad and yet marketed otherwise in a fashion that makes me call in question whether or not "Cassini" was real or just a ploy to disguise a nuclear satellite. And I (before seeing this) thought the Moon landing was real!
Actually, this story could be improved by adding a few more instances of the word "actual".
I don't quite understand the trajectory of the probe. For example in the last shot, it swoops past Mimas zooming straight toward the Saturnian surface, then appears to change direction curving vertically, passing through the rings (why no hail of ice damage?), then swoops back around and turns around heading toward Encledatus at top speed. How is this even possible?
You misspelled "Enchiladas" in the summary.
I keep thinking "What is that, a sphere with a lambert shader? Some kind of procedural ring texture on a plane? Might want to add some rocks while passing through the ring so it doesn't just pop. Those shadows are way too sharp, might want to turn on raytracing for those."
It sucks that I can't appreciate this properly and my brain just keeps interpreting it all as fake because my only other reference for something like this are 3D renders.
Also, I've loved Agnus Dei ever since hearing it in Homeworld.
The video makes it look like it does. Or is this a consequence of the zoom factor used, and did Cassini pass the equator outside of the rings?
Whenever I hear this song all I can think of is those poor Higarens.
If you (wait until it's not Slashdotted, then) go to outsideinthemovie.com, you'll see it's a project mostly done in Adobe After Effects, taking raw Cassini imagery and slicing it up and animating to create perspective. No texture mapping onto 3D objects, and not thousands of raw images lined up into a movie (they don't exist in that kind of quantity)
Pretty impressive given the tools he's got. He mentions on his site he's 'making an IMAX movie in his basement.'
If you posted this video without the supporting text, not only would viewers assume it was CG, they'd say it was bad CG.
As great as technology is, sometimes it spoils us, sadly diluting our perception of awe-inspiring things such as this.
I think the majority of the problem is that we are accustomed to seeing atmospheric effects in lighting. Space doesn't have that, so your light genuinely is a single point-source. The images thus look like what you would get from simplistic point-source renderers, with sharp shadows, no diffusion and no ambient light, which causes our minds to classify them as fake.
Call Luke Skywalker! You can see the death star at 1:30!
I saw the Deathstar!
$ whatis msft msft: nothing appropriate
Did anyone else see the death star? Oh my fucking god.
There's some debate here over whether the video is CG or used CG in conjunction with the photos. The NASA Astronomy Pic of the Day article mentions that this video is a part of an upcoming IMAX film called Outside In, who's website has some further explanation on how they're making the film. Of course, the APOD article is a paragraph in length, so an entire website might be a bit much for some to read.
Kharak is burning.
The summaries are very misleading. They misrepresent this film as if its actual motion video taken from the probe's perspective. Even the video itself claims no CGI was used, but CGI WAS used! The website even tells us how it was made: "Using hundreds of thousands of still images manipulated to create full motion, using “2.75D” photographic fly-through technology." That's why there are so many errors in perspective and the probe's velocity and position don't make sense. This is a neat FANTASY fly-through made from real photos that people are confusing for the real thing. You people need to start using your brains, for christ sake! Its unfortunate that people feel the need to misrepresent this video, and even worse that everyone just eats it up without questioning what they see.
It was created in order to inspire people and show them the beauty of our solar system. The website even states that this is an "...art film that takes audiences on a journey of the mind, heart and spirit..." but it holds absolutely NO scientific value what so ever, and should not be seen as an accurate portrayal of the Cassini mission.
Hi /.ers,
In case you have never before used Universal Subtitles service,
look how nice work someone do with it (all credits to Usub):

enjoy,
F.
had someone rendered it in 3ds max, none of you would know the difference, since this "original" looks fake already
