Hi all. I put together a work in progress demo of a simple physics engine that can handle particles connected by springs. This uses a method known as Verlet integration which is stable and efficient, so you can simulate dozens of springs in real time.
The cart includes 4 demos: a pendulum, a string, a cloth, and a deformable rigid body.
The library implements the approach laid out by Thomas Jakobsen in the article Advanced Character Physics. The syntax is inspired by the physics simulation library
