I've been getting some requests for wooly paths source code for the past few months so I decided to clean up an early version of it in VB.net and hand it over to the internet. Grab it here.
I've simplified it a bit in an effort to keep the code clear. Unfortunately, in doing so, it takes a bit of a speed hit since some optimizations regarding large particle populations were left out. Feel free to use it / tinker with the source code however you like. All I ask for in return is street cred.
Platforms: C#, VB.net, Grasshopper, Rhino
