I highly recommend watching the relevant section of that video (4:38 to 8:59) and then implementing it yourself in whatever system you know that can draw lines and circles (I did it in Godot; it took only a few minutes to learn enough Godot to start on the algorithm).

It's absolutely mind-blowing that so little code can produce such a beautiful result. It's also fun to play with the parameters and see how they affect how the cloth feels.

would you share your godot code to github?
