Comment on Show HN: Physically accurate black hole simulation using your iPhone camera

I wonder if this would be better as a webpage and not an app. It’s something I want to share far and wide for everyone to play with for five minutes. But as an app, most people I send it to won’t go install it.

I’m no astrophysicist but it all looks doable with the camera API, canvas API, and WebGL or WebGPU shaders. That actually sounds like a lot of fun.

Yes I was wondering if they used shaders to implement this.
