Show HN: Flight-Viz – 10K flights on a 3D globe in 3.5MB of Rust+WASM

32•coolwulf•4h ago

I built a real-time flight tracker that renders 10,000+ aircraft on an interactive 3D globe, entirely in the browser using Rust compiled to WebAssembly.

It render extremely fast on my side (firefox, macOS). Which UI stack are you using? Is it egui?

coolwulf•3h ago

It's mainly eGui + WebGPU

Can you add pinch zoom?

coolwulf•1h ago

Currently I developed this for desktop browser, so it might not work well on mobile. But I will improve and update it.

You should be able to do pinch zoom support for laptops with a trackpad, too. I think it would be

window.addEventListener('wheel', ... )

Fantastic work!

Ok, I'm on desktop now. And I notice another "issue". When I use my mouse wheel to zoom, the point that my mouse cursor is on is not stationary. This makes it hard to zoom in on e.g. a specific aircraft or landmark.

Why is there almost no traffic in places like South America (other than Brazil) and Africa? Data set or reality? Not much in China/Russia either.

coolwulf•1h ago

The current data is from OpenSky, mainly north america and EU.

When you zoom in to the street map level, the planes are practically invisible with their color and thin borders. Pretty neat though, that's a lot to load and keep smooth.

Impressive. The planes should probably scale up a bit as you zoom though, they become impossible to spot.

I'm surprised all the flights in the world can be represented in a <500KB api call

Could probably extrapolate positions based on heading and speed, to do some fake "real time" positions.

Wow. I won't give you a feature request :) just appreciation.

It really puts into perspective the magnitude of air traffic when you have this visualization.

There's something a little off about the projection logic when you drop into the Leaflet view, you'll notice that when you pan around after zooming the planes shift their location.

Very cool demo though!

Need to check my calculations. Thanks for noticing it.
