We are simulating physics down to the stupidest level possible and you’re trying to beat the clock by femtoseconds.

The above implementation which I have ported to rust is PBD. In future I want to implement XPBD. The above implmentation has gradient functions I can use for this. Then start working in porting the particle system to the GPU.
