[Boids Test - Processing - GHowl - Grasshopper]
A proof of connection test between Grasshopper and Processing using the Ghowl UDP interface/ examples.
This uses Daniel Shiffman's implementations of the Craig Reynolds Boids behaviors in Processing. Luis Fraguada's gHowl interface connects the processing sketch to grasshopper. I used the Kangaroo particle trace utility to follow the movement and edited out the lines where the boids crossed between the top and bottom of the sketch area with a distance threshold for line segment length.
