algorithmic modeling for Rhino
Ability to place as many points as you'd like and designate them as attractors or repulsors, control minimum and maximum vector values per attractor/repulsor, and differentiate between resulting geometry by a length threshold. Repetitive node sequences captured as clusters. Works for any curve set with a consistent number of vertices per cell. Definition attached. For original Grasshopper 0.6 definition check out http://www.co-de-it.com/wordpress/code/grasshopper-code under "Hexagonal Field."
