i built a real-time 3d positional tracker in the browser renders in ~8-10ms

i did this 17 years ago 😉

nice!

i miss flash so much. imagine what astra could do with flash

try it out here:

ryan rouch, vogel browne

Stop with the indian ai linkden slop posts please there are multiple projects that already do this

Gotta pump those response numbers up

you should drop this as a space on 🤗

how

you can just ask your agent to deploy here, but saw the link above which is neat

nice:

which lab has the model "i" ?

That's insanely slow. I was doing fiducial marker tracking via webcam at 2-3ms in 2007.

so cool haha

really cool

What if you put all frames into a buffer (seperrate mode), do the tracking and render per frame and then play those frames? It will be slightly delayed, but accuracy should be very high right?

Welcome back Invizimals

so smooth 🔥

Interesting, i remember using some kind of synonym software to track my arm movements. completely forgot what it was.

How are you handling camera calibration? Normally for AprilTag tracking you take a bunch of photos of a calibration board at different positions and angles to calculate your camera intrinsics. If I were to guess, I assume you're just picking a reasonable assumption? That'll technically work, but AprilTag can actually have centimeter localization accuracy with good calibration, so it might be worth exploring using mrcal to generate good camera intrinsics.

Neat!

Open source ?

That is a remarkably tight render loop for a browser-based tracker. The interesting product question is how you keep the interaction feeling stable when the input gets noisy.

No Dax Demon on it? Wtf is this demo

pretty cool!

Now make it track a mosquito

Man taking credit for clankers work!

But what's the use case? Very impressive btw!

I remember when doing any kind of decent CV in the browser was absolutely black magic. I even wrote a paper about realtime face detection using flash in 2009 😂

Try doing it without the robo-QR codes

not fast enough man

What is it called?

Sub-10ms render times in the browser means you're hitting 100+ FPS locally—WebGPU and Wasm have made the browser a legitimate spatial computing engine.
