Sorry, I assumed you were talking about drawing animations for spritesheets or something. There was a similar conversation elsewhere itt The drawing is webGL, but the cloth physics are actually webGPU. The cloth solver also doens't depend on three.js- you should be able to use it with whatever webGPU renderer you have. It's typescript but 100% vibed. I don't look at the code anymore. Oh shit yeah don't put the LAFAN1 animations into your project if you're gonna publish it- those are copyrighted…
