Particles

Monday 30 April 2007

Particle simulation in Actionscript. Up to 10 particles in a simulated "container". Occasionally explodes if particles get too close (due to dividing by zero or almost zero) - common with higher number.

With one particle interacting with the container the path is regular and uniform. But add one more particle and things get crazy and chaotic. Essentially it's the three-body problem, with the container (a bowl, described by an equation something like z=kd6 where d is the distance from the origin) as the third "body".

[Update: Using SWFObject to embed Flash now. Fingers crossed.]

Cute! I had to view the source and cut-n-paste the URL to see it in Safari, just so you know… something’s up with the Painful Layering Of Object And Embed, I guess.

Odd - it’s displaying fine on my copy of Safari (2.04). I’ll have to look into it and put it up using better code. So much for Flash’s auto-generated HTML.

I love the way the lines meander so distractedly. May have to find a way to output them as curves.

I’ll put the source files up eventually too.

So THAT’S what particles are up to when I can’t see them! I do enjoy the green explosion when the atoms occasionally smash.

Very cool!

It might be my ad-blocking stuff, though it didn’t look like it when I looked at the source. At least today your site served its CSS up for me!
