Moshpit

A two-dimensional model of moshers, similar to a disordered gas.

Based on research by Jesse Silverberg and Matthew Bierbaum. See: http://cohengroup.lassp.cornell.edu/projects/collective-motion-mosh-pits

is it related to the soon-to-be-released commercial game moshpit simulator ? https://www.youtube.com/watch?v=V_IObmyIFbE

I'd never heard of that game until now. Interesting...?

I'd be curious to hear from anybody who uses this about what I could add to it. This is a pre-release that could easily have more features. But, what features?

here, max hangs infinitely when i try to open moshpit.maxhelp (osx yosemite)

Thanks.

Somebody else has figured out the maths for this simulation. It's a bit tricky as it is, so probably won't add additional behaviors. Figuring out the collision energy might be possible, though.

I'm thinking I should dump the positions and force values for the red moshers out another outlet. Or, send all of them as a list like , , , . If I was outputting everything, it would be quite easy to add a flag to suspend drawing, or make another object that just didn't do that.

I did have a prototype version in Javascript and and the framerate was really miserable. It's hard to say if it was the drawing or the math that was slowing things down, or both. I'm curious to implement this as a particle system in Jitter, but I'm not sure how to do that.

(it's working with max 64 bits, but makes 32 bits crash)
indeed it's fun, and more datas for sonification or custom vizualization would be cool :>

I've just added a v0.2 that outputs all of the particles out the right outlet. Also, it has an attribute to turn off drawing in the object.
