Can a material point method with implicit time integration be provided?

[ReFantasy]

I'm very interested in the Material Point Method (MPM), particularly the optimization-based implicit time integration mentioned in the paper "Optimization Integrator for Large Time Steps." However, there are very few simple and easy-to-understand code implementations available on this topic. Could you provide a relevant implementation for elastic body deformation as a learning resource?

https://github.com/penn-graphics-research/HOT is the current SOTA implicit MPM implementation.
We will also consider adding an example in this repo.

Thank you for providing the reference code implementation. We also look forward to the examples in this tutorial.
