I’m pretty happy with how the Verlet integration engine I’ve been building is turning out. I’m using it for the next virtual pet animal I’m working on. It’s somewhat cleaner and much more extensible than the system I hacked together for my monkey. When combined with my wide-curve-drawing routines, you can create some interesting-looking stuff (IMHO :) ). Once my new pet is done you’ll be able to see it. I might upload a simple demo before then, though…
I’m considering releasing it under an open source licence of some sort… not that it’s that amazing or awesome, but it could be useful or interesting to others.
