r/LiDAR

I built a browser rendering library specifically for live LiDAR and point-cloud streams, published v0.1.0 this week.

It handles the problems that come up with live data: memory that would otherwise grow without bound (bounded ring buffer, configurable ceiling), main-thread stalls from parsing (dedicated Web Worker), and wasted render budget on off-screen or low-priority points (importance-weighted GPU sampling via WebGPU compute).

Supports WebSocket, SSE, and ROS rosbridge as stream sources. Also loads COPC, LAS 1.0-1.4, LAZ, PLY, and XYZ files with progressive rendering.

Demo (synthetic Lorenz attractor stream, not real LiDAR):

This is a React library, so it won't replace desktop viewers. But if you're building a web dashboard that ingests a live sensor stream, it handles the rendering layer.

I'm posting this because I want it scrutinised by people who actually work with this data. I don't think what I've built is perfect and I'd genuinely value feedback from someone with real LiDAR use cases more than anything else. If something doesn't map to how you work or there's a gap in what the library handles, I want to know.

I'm looking around trying to figure out what would be best for scanning culverts and bridges. It really doesn't need to be ultra precise, and not in relation to any actual system. Precision would be nice for measuring deficiencies only. Typically we will walk through these structures, then just have a written inspection and maybe pictures. I'd like to be able to create a digital twin, and while walking through be able to tag locations with problems so it's easier to keep track of. I've seen some that also seem to provide 3dgs integration, and that seems great for texture quality. Options like the Slamtec Aurora seem interesting, but I can't find many examples. The Leica BLK2go seems like possibly the best ready to go implementation. Any thoughts or suggestions for such a use case?

Would anyone have access to aerial or lidar maps from 1998-2000 of Newburgh, NY? Specifically near Stewart International Airport? I’ve done some research but I haven’t had much luck.

I want to convert a massive pointcloud to a viewer friendly format like copc. What I have in mind is essentially converting terabytes of data like the Dutch height scan model: http://ahn2.pointclouds.nl/

What conversion tools are you using for very large datasets in 2026? So far, the only valid solution I have found is copc_converter , although I’m very happy with it, I am still struggling with problems for datasets of such size. (But the devs are very active and improving quickly)

I am thus wondering if other software exists and if copc is the right choice for something the large. My final goal being on one side a web viewer of this dataset and on the other the compatibility with his tools to download full res small sections.

Hi everyone,

I’m looking to start an as-built measurement company focused on smaller residential homes (around ~2,000 sq ft).

I recently had a demo of the FARO Blink, and on paper it looks really promising. That said, I know the BLK360 G2 is a proven, solid option in this space.

I found both at similar prices and want to hear which direction you would go ?

I recently came across two vans that did LiDAR mapping and pavement scanning. The company went out of business and ended up with the vans. I’ve sold the pavement scanners in the GPS, but I still have the cameras in LiDAR in a bunch of computer equipment that were in the vans and I don’t know who buys stuff like this. Just looking for a group who might buy the heavy duty cameras that mount on the top of the vans and the LiDAR equipment.

I posted here some time ago about turning point cloud to a mesh. With your help I got it working and now I want to know where I can learn how to work with this type of data (CloudCompare as it’s free). I like playing with it for 3d printed cities but now I think it’s time to go a bit deeper. Why? I don’t know as I don’t have anything but this personal project going on but I believe it’s something that can be useful in the future. There are a lot of tutorials out there but I would like something more or less structured (not just one feature that I may need at the moment) to know the base. Any help would be appreciated

Babies juxtaposed onto the front of my LIDAR scanner via duct tape keep messing up my data, need help

what's a good cheep LiDar scanner that can do whatever the iPhone LiDar Scanner can do.I heard from someone that it s an app on the IPhone that is good and can mesure the width and height of a tree.I would realy apreciate something that is not complicated and cheep.Thank You

please recommend high accuracy, high resolution, pure solid state, close range lidar

to monitor human traffic in a room.

Anyone here have high-fidelity lidar equipment working in or around Memphis, TN?
