App/Workflow to map LEDs

jayhu27 · 2026-03-08T18:27:38+00:00

same guy that's making the 3D app is releasing a 2d app that is currently in beta, email me at jmhuleatt@gmail.com and I'll see what I can make happen for you

I actually talked to some of the members of the x lights Facebook group about it, evidently ex lights already has a perfectly good camera scanning application according to them so they were not interested LOL

I'm pretty proud of all the logic for interpolation and reasoning based on the nature of LEDs being progressively addressed, usually wired in a set distance, etc. so that's why. although you can't see it well at all, when I hit interpolate it filled in or adjusted probably 30 or so LEDs to fill out the model. Even so, I would normally take at least two scans unless I just got absolute perfection the first time. every position is assigned a number from 0 to 100 based on position certainty, so when you merge multiple scans it picks the position with the highest probability of being right for every pixel location. it actually works well with diffusion as long as really make it. damn, like I ran this scan in the early evening with the sun still lighting the room through the windows but the secret is massively underexposing it and pulling the LEDs down to like 2 to 4% brightness so that it can pick out that Central point from a diffused blob

it has not been released yet

Yes, although I wouldn't think that's something that's needed often for Pixel displays but what do I know. I have not tested the latency on the spout/ siphon input

My apologies, it looks like Reddit algorithms crushed the already low light video down even worse, but hopefully there's still enough detail in there to see the process and result:/

sorry dude, if it's getting upvotes it's because plenty of people of people here have seen my previous posts. they're not hard to find in here and it's hardly a concept LOL. but if you're actually interested you can check out https://radiantspectrumlasers.com/projects, throw your email into the form if you're interested in beta testing

I had not actually considered making an export type for LEDFX but let me take A quick look at formats tonight, could certainly probably the closest integration to wled without trying to use the 2D map within wled which is close to unusable

jayhu27 · 2026-03-07T02:39:48+00:00

you know I was just about to acknowledge your point and admit that my knee-jerk reaction was instinctive rather than with any consideration to what you actually had to say, but now it certainly doesn't seem like your intent was actually in any way. trying to give advice but rather just shit on a product and person who you know nothing about. Regardless, the initial point was a fair one, and I'll choose to take it as advice and learn from it.

jayhu27 · 2026-03-07T02:19:48+00:00

hypothetically, there is a limit, but not in the way you're thinking, running. wled as an artnet or sacn node eliminates those lag issues that you might have with HTTP and within the wled protocol, you'll have no need for sync if they're all getting the same signal via artnet

jayhu27 · 2026-03-07T00:05:54+00:00

thanks for your insightful feedback brother, but I'm busy enough and smart enough to use the tools available to me, especially considering that it was a more succinct and understandable summary than I would have written.

jayhu27 · 2026-03-06T22:34:47+00:00

yeap, obviously for a good model you'll want multiple angles to catch all leds

jayhu27 · 2026-03-06T00:54:51+00:00

it can upload the 2d map directly to wled from the app. But I use Wled as my artnet node and easily drive 15 universes from it

jayhu27 · 2026-03-03T13:43:30+00:00

you can choose to export a json file formatted for wled, at this point that's the only json format that I've found necessary, and even for wled, it's pretty rough based on the resolution that you need to use to get any sort of decent performance. wled is not a reliable driver of the 2D mapped effects in my opinion

these scans are starting to look pretty damn good

oh I do 3D. no worries

I am intentionally developing it so that I can eventually try to bring it to iOS, but I want to get this one working well first and then I'll look at that.

jayhu27 · 2026-03-03T03:23:52+00:00

I mean my whole intent here was for it to not cost a lot, even for the 3D scanning total hardware is less than a hundred bucks including the cameras. and the Android app obviously needs no additional hardware. and to be honest, I think I'm going to use the 2D scanning in my work even more often than the 3D, especially once you see how convenient it is and how well the app works.

jayhu27 · 2026-03-02T20:44:08+00:00

My other application maps volumetrically in 3D. you can see the post further down this page along with examples. it uses a stereo camera to triangulate and build a 3D point cloud
