Show HN: Real-Time Interactive Fluid Simulation on Vision Pro

I made this with the Metal APIs in VisionOS 2.0. It now gives access to low-level mesh features and buffers directly, meaning lots more particles are possible (around 5-10x)! The hand-tracking also seems much, much smoother.

The fluid sim is a version of SPH running on the GPU, with the particles drawn with billboarding orientated to the headset position.

Would love to hear any feedback - for anyone with a AVP, it's available to try for free here:
