I contributed a 9000 word article about making this effect! note you will need a browser with WebGPU, and for reasons I don't quite understand, I get bad performance hitches on Firefox, so unfortunately it works best in Chrome. native version can be compiled from the source here

It's about divergence-free fields, and writing cross-platform compute shader programs using Rust and wgpu! If those sound like things that might interest you, give it a read :3

You should also check out my friend shoofle's article (that is, @ada-adorable!) on async gameboy programming with interrupts if you wanna read about something more oldschool! <3

I was debugging the wrong part of my code for literally days. Checking my vector math and rewriting it a couple of times. I tried multiple new approaches, but things still looked wrong. Then I looked at a part where I did simple stuff: copying data around to the shader.

material.control_point_positions[num_control_points as usize].x = point.position.x; material.control_point_positions[num_control_points as usize].y = point.position.y; material.control_point_positions[num_control_points as usize].x = point.position.z;

Can you spot the mistake?
