Production Update #2, with first image =)
| Posted January 27, 2012 by Kalle Max Hofmann 1 Thumb-up |
Hey all you stargazers out there,
here's the next production update.
Things have been going a little slowly recently, at least for my taste. But, rent needs to be paid and people to be fed, so most of us engaged in paid jobs. Still there was enough time to process all the pictures we're going to use in our first episode :D
As an example, here's a little rendition of an aerial view of Neptune's moon Triton, which I also shared with the TRANSNEPTUNE production. In the final version, it will have enhanced effects to make it look more real. And it will be three-dimensional, obviously :P
Still kind of good news that we are ready to start actual production now. The last question marks for Episode one remain the space station and the green screen shoot. But first, I need a new computer to do the actual effects work - my 2007 Mac Book Pro is constantly puffing out little white clouds lately ^_^
So - maybe some more paid jobs for the next couple weeks? We'll see, but we're definitely on the right track!

The atmosphere is only 1.5 mBar, which is nearly vacuum.
Geysir do emit ice particles, and they are affected by the thin atmosphere.
thanks for the detailed corrections, Thierry! I will get to work on them asap =)
What do you think about the question how Triton's atmosphere could be visualised from the surface? It's supposed to have only 1.4% the density of earth but... what does that make it look like? And what about the ice particles emitted by the geysirs... do you think that stuff could look like some snow dust in the wind, like on earth? Keeping in mind that these particles are mostly moved by gravity, and not wind... not so easy to imagine all that...!
The picture looks nice, but since since needs to scientific accurate, here some changes:
-Triton orbits Neptun 350'000 km away, Neptun should be four times the size of Earth seen from Moon, or twelve times the size of the moon seen from Earth.
-How Neptune is position in the sky, means the camera is places at the pol of Trition, otherwise the rising Neptune must titlted inverse proportional to the lattidue. Also the thing is a bit more complicated since the orbital plane is tilted by 30° comapred to the Neptune equator, and Neptun is tilted by 28° compared to the ecliptic, whih means that Triton axis is tilted by nealry 60° . (Earth is 23°)
-The surface of Triton is more readish. This should be similar to the picture from Voyager 2, which people know.
-Neptune cannot be backlit at all, or extremly low, like the moon does with Earth, but that's not possible in this constelaation like in the picture.
I would dim the star

Yes the atmospherical detail is something I really wonder about. There are geysirs on Triton that shoot out ice fountains, certainly that debris could be shown flying about.
And I think you're right that it could look more impressive (and perspective-wise clearer) if Neptune is slightly below the horizon. The Transneuptune guys have calculated that Neptune would take up to 60% of the field of vision when standing on Triton, but I can't quite believe that... I've seen some NASA illustration with a Triton surface scene and there, it was smaller. Or wait, was that in this BBC sci-fi-documentary? Have to check that right away ^_^
Oo.. got one more idea.. I'm not sure of the perspective how big Neptune would actually look like, but how about making it significantly bigger and put part of it below horizon?
Well you have that nice haze on the Triton's surface and more on the left. I'd try giving some haze over Neptune too and especially pronounce the turbulence details so that it clearly says "I'm closer than Neptune". :)
You're probably right that it has to be darker. I wasn't thinking of a bounce though, but since Neptune is made up mostly of atmosphere and a only relatively small solid core, I thought some of the sun's light could kind of shine through this cloudy soup!
Unless I can get the opinion of an expert on this though, it's probably safer to go with your approach and make it pitch dark :P
Any other ideas to make the visual integration of Neptune smoother?
Nice to hear things are progressing!
Critique up next! As an astronomy hobbyist & vfx artist must say the back lit part of Neptune does now work for me here. As normally the back side should be completely dark, now it feels more like Neptune is a small sphere floating on the surface of Triton from which it gets the additional bounced light to the back side too.
