I built an interactive cloth solver for Apple Vision Pro
A bit more context - the cloth sim is part of my app, Lungy (https://www.lungy.app). It's designed to be an active meditation / relaxation app, so you can play relaxing instruments in space and immersive breathing exercises. The original Lungy is a breathing app available for iOS, that uses real-time breathing with interactive visuals. The cloth sim is a Verlet integration, running on a regular grid. For now, I have tried a couple of different cloth scenes - a sort of touch reactive 'pad', where different parts of the cloth are mapped to different sounds and a cloth that blows…
In plain words
Lungy is a meditation and relaxation app for Apple Vision Pro that combines interactive cloth simulation with immersive breathing exercises and spatial instrument play. The cloth responds to touch and breathing, with different areas mapped to relaxing sounds. Built on Verlet integration physics, it extends the original iOS breathing app's real-time visual feedback into an immersive spatial experience. The app is available free on the App Store.

For now, I have tried a couple of different cloth scenes - a sort of touch reactive 'pad', where different parts of the cloth are mapped to different sounds and a cloth that blows in sync with breathing. The collision detection is a little bit tricky with the deforming mesh, but seems to work ok overall. Overall, it seems like a cool interaction to explore. The cloth sim is live on the app store now (and free) - would love to hear feedback from anyone with a Vision Pro.

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
