Thank you so much for all the effort you are putting into each of these tutorial. it is absolutely great!

Very nice tutorial. Looking forward to tutorials on dynamic topology change (tear, fracture)

the channel that just keeps on giving

I'm curious how to add other important features to this, (self)collision, wind forces and turbulence, air drag etc. And how to connect it dynamically to other physics objects. I guess we'll see this in the future

Great series! I'm wondering if there's a way to implement soft bodies, cloths, strings, and particles (e.g. for fluids), in a way that allows for easy transformations from one type to another. Essentially, treating soft bodies, cloths, and strings as nothing more than meshes of particles that can be deformed and torn apart to create other soft bodies, cloths, and strings, but all cloth and string behavior is emergent from the same physics as the soft bodies, plus the fact that they're thinner or completely flat. This would really be great to build a game where players are able to modify the world in any way they would like in order to build anything.

I would love to see a video talking about your small step XPBD paper. Especially how to handle collection detection. Great job on this channel by the way!

Awesome ! Thanks a lot!

Great video! What do you mean by "weak in flat state" at 2:55? That it's harder to keep it straight against gravity for example? Is this weak vs strong issue present in the 2D case as well?

Really nice work :), Matthias. I am a researcher and doing an explicit tracking survey. I wonder if you can share your implementation of grid-free tracking method? I would be pleased to have it for a comparison :).

Is there any place we can ask you questions about PBD in general? Would love some kind of Q&A page where devs can ask about various PBD aspects! Would be very valuable! I've been diving deep into PBD in my sparetime, reading papers and implementing. Having a lot of fun, but got many questions, for example regarding unification of constraints, e.g. constraint order, local vs global relaxation, what constraints to pre-stabilize etc., and very curious about the incredible method in your "Small Steps in Physics Simulation " paper!

Amazing explanation. Thanks. Do you think that shrink and grow the constraints connections along time could work in your implementation? In blender the cloth solver is very old, there's an option there called "Shrink" to control the cloth size via simulation with vertex groups also... I'm following your youtube channel and I see you implementing some things into blender... I'm very curious about it(specially softbody)... are you working in Sofbody implementations in blender?

Do I see similarities to Two Minute Papers here?

3:54 is confusing, is {1, 2, 4} meant to go to 2 and {1, 3, 0} to -1?

is {1,2,4} supposed to have edge neighbor id '4' instead of '2' at 4:08? I'm a little bit confused...

I am always amazed how much you can simulate in so little code! That said, your cloth simulator would probably not pass the cloth drape test, commonly used in the industry. Different fabrics can be characterised by draping the cloth over a circular disc and countinquantifynig the folding pattern that's created. Particularly, fabrics that stretch on the bias will be hard for your model to properly simulate, I think.
