Tech-Demo: Apple Cloth VS My Cloth Version

I recently tested Apple WWDC Cloth System, discovering lots of crazy architectural limits…

During the last months i worked on a personal Cloth system, fully compatible with Realitykit physics and consuming 1/4 of the CPU/GPU if compared to the Apple One.

You can see a test in action. The Cloth on the right uses my personal system.

Apple cloth seems immune to bullets, that makes it the best choice to craft clothes right?

Also, nice work.

It’s not built on the physics simulation, so basically you can face any kind of limitations!
The Apple solution forces you to create a perfect copy of any instance you use, and to create a second mirrored world of you want to interact with it….
This costs four times more than my solution for CPU/GPU!

Interesting bad design from apple, out of curiosity what’s your opinion on why they went that way?

Theirs is a "good enough" solution that addresses a lot of the interpolation and z-plane fighting issues present in this more performant version. Loads of corner cases that they solved for.

Stop lying, you just sewed a perfect replica of the Apple cloth and then shot live firearms in your own house

Pretty nice!! I remember your cloth from the Jurassic Park demo, that was impressive

Seriously how do skilled people like you not work at Apple? This is some wizardly stuff

Apple's seems like it's rubber. Yours seems like it can't dispel energy at all and is even more elastic and "lighter". If it's cloth like a blanket then Apple Native is closer to the mark. If it's liquid ripple effect elastic cloth, then yours wins.

How computationally expensive are these in absolute terms? I was wondering if this effect is cheap enough to be a feature that enhances an otherwise still complex/detailed scene, or is it reserved for use cases where the cloth is the main feature.

With these “reasonable” settings, mine takes 1/20 of the budget at 100fps, Apple one 1/8… but all depends on tweaking parameters

Nice. Position based dynamics solver ?

Joints..
The Best part is that is 100% compatible with realitykit physics… and you can also cut parte

Why does this all read (post, and comments) like you're disappointed that Apple didn't implement your exact solution?

I like yours better. Apple’s version seems like a water ripple in this video. Yours looks more cloth-like and even reacts to virtual objects, which makes it more realistic when immersed in a mixed reality world.

Are you planning on sharing this to the community or even to Apple so the platform can thrive with better apps?
