The Moon’s Formation

without comments

Today I finally got the go ahead to share one of the astronomy animations of late.  It looks like we may change something about the sun on the first one, but this one is staying as is.  This was definitely the crazier of the two to work on so far.  I don’t really ever get requests to crash things when I’m making bio animations.  So I did a few tests in advance of taking this one on, where I discovered the Voroni Fracture, which is super fun, especially when combined with the push-apart and random effectors.  Unfortunately, by the time we got the textures fully set and introduced a molten core, every scene that used Voroni fractures wound up taking forever to render.  There are spots where I would have liked to do it a few more times to finesse some of that stray space debris and get it just so.  But overall, I learned a lot working on this, and it was fun to try something different.

It’s been a while since I’ve been able to post anything fun from work on YouTube.  For a while there, most of my animation work was either going into larger interactives and needed that context to make sense, or was really small, and again best within the context it was being made for.

I’m looking forward to doing more of these.  And when we get things settled with that first one I’d like to show it off too.  It’s less smash and more elegant.  I think it’ll give viewers a good aha moment, and well, that’s my favorite part of working on things like this.  Well, that and the part where the details of my job involve all kinds of cool scientific knowledge.  Really, prior to making this, I don’t believe I’d ever heard this explanation for how our moon formed.

Oh, and I can’t forget to mention this awesome find for textures.  I only used them a little in this animation, but I’ve gotten good use out of the textures that are freely available from Solar System Scope.  It’s a lot like taking them directly from NASA, only these folks have already done the work of taking NASA’s telescope images and stitching them together to make a perfect texture for application to a sphere in whatever 3D program you might be using.  It’s really made working on these kinds of images nice.  So big thanks to them, and obviously to NASA.
