I’m a big fan of gummies and wanted to create some squishy animations. While looking around for exisiting soft physics systems I stumbled upon this paper:

I then went down the rabbit hole of trying to implement this myself in Unity. The last time I had read a paper was in college so it felt like I was in school again. Some details on my implementation:

Built with Unity jobs system, with parallel jobs
Implements Various constraints including area preservation, hinges, friction
Script for triangulating SVGs to be able to create arbitrary squishy objects

I’ve yet to actually use this engine for anything but I’m sure to revisit it someday.
