Matter collider
Dec 17th, 2009, 3:41pm  
After some rather lengthy discussion with Giles and liudr I was inspired to add some attractor forces to an old sketch that had already seen some improvements as a result of aforesaid discussions.  The net result is now on OpenProcessing:

Thanks to both Giles and liudr for providing the inspiration Smiley

Really cool. I remember a sci-fi novel by Stephen Baxter in which people live in a universe where gravity is a million times stronger than it is in ours (or maybe a thousand...not sure). Anyway, people live on these tiny worlds, and you can actually feel the gravity from another person tugging on you when they walk past you.

I was reminded of this by your sketch. If you made the window bigger, and the balls smaller, you should be able to have a cluster of balls in the middle and then grab some of the balls and throw them so they orbit around the central cluster..... that would a very fun toy to play with. Maybe you could have two big clusters orbiting around each other (like a binary star)?

Thanks.  I've just uploaded some changes, including optional polarity as inspired by your sketch (not sure I've handled it the same way as you as I couldn't get online whilst I was working on it).  See my comment on OP for full details.  There's now plenty to play with; though it might be interesting to give a mix and match set of options for attraction/repulsion.

As for resizing the sketch - in my experience the larger you make it the more it affects performance (though there's definitely some optimisation that could be done to compensate); but it's coded in such a way that you can set the sketch size as required and controls, windows etc. will all be in the right place - that's one advantage of avoiding too many magic numbers Wink
