Grasshopper’s scripting capabilites are now a huge super cool feature, especially if you’re coding in visual studio (c#) and then pasting the shit or making dlls. I did this some time ago when i suddenly realized that you can declare your own static variables inside scripting nodes (and these guys hold up their values during the updating procedure). And the vector math is already there too.

This is an implementation based on Craig Reynolds‘s neurons, and a little bit on Daniel Shiffman’s processing example (which was updated and used some time ago for this.

Now, if somebody will be nice and implement some collision detection…

PS: I will upload the def. soonish (i have to clean it up a bit first). Ok i didn’t clean it up; here’s the link.

Here’s a new 10 day link: http://dl.transfer.ro/boidsT-Transfer_RO-16Nov-ad56f6.zip

Final link, stable and sound: http://improved.ro/Grasshopper/boidsTCAV.zip

Using processing to make a circulation study in a public area. It’s for the current school project. More details later.

I’ve used Shiffman‘s boids sketch as a start, and gradually started building up with some attractors, Point Obstacles (which are attractors with negative pull basically), and Linear Obstacles (which were a little bit tricky, but this helped out a lot). Also very inspirational were kokkugia‘s experiments.

When it’s nice and propper, I will  add some details and upload the code/sketch.
