Kons-9 3D Common Lisp system – web-like structures using mass-spring model

Been plugging away at kons-9, my IDE for 3D production.

Some basic UI, Windows port, and most recently a mass-spring model for animating flexible geometry as well as generating web-like structures. Sample video in link.

Added SDF functionality as a test.
