Technical Snow Reference

I thought it'd be a good idea to look at a few of the important papers about snow from siggraph over the years. This one talks about how to correctly model fallen snow. It goes into a lot of detail and gets very physically accurate, but the basic idea is simple. I actually tried it out in Houdini and it's not too difficult:

This paper outlines the method that pretty much everyone used to simulate snow before Frozen. It would allow us to easily get footprints and simple packing motions. It doesn't look incredible, but it gets the job done. And it's pretty fast and cheap.

And then, of course, there's the paper about the snow from Frozen. It's a completely new method that's very complicated and time intensive. But it looks amazing.

And here's a really random bit of reference from the internet. Frozen bubbles! How cool is that?
