Title: Project Rosseta. Landing on a comet.
Post by: borisquezadaa on 2014-11-11, 14:00:36
Just out of my head.
Did you know that were about to land on a comet in a few hours?.

In space there are no secondary bounces, look at this flickr account with photos of the comet.

They even do a short film to promote that. (I mean why on earth they need that to promote it?... people are seriusly dumb this days).


Slingshot a satelite in to the void so after 10 years it can headshot a comet. I defy any sniper to best that!. ;)

(Wonder if there are some video footage so i can manage to do some photogrammetry reconstruction of it it would be a cool 3d model to print).

What do you mean by secondary bounces? GI? Of course there is! :)

Just kidding, they say that the comet has a very dark (darker than coal) surface... and there is no geometry near to give back those nice GI bounces. They have to process the images taken to make something "watchable". ;)

There is this relatively common misconception that GI happens because of air scattering, so there is no GI in space. I heard it even from one of the professors at my college :D

There's no GI in space nor on earth, it's just BOUNCING... (http://gifsection.com/wp-content/uploads/2013/11/Rachel-Williams-bouncing.gif)

I agreed with Romullus, that's some serious Brute Force bounces. I would definitively positively gonna remember that from now on. http://goo.gl/deY0wE (http://goo.gl/deY0wE).
