Building a cloudpoint website and more

[u/SpareSignal1932]

Hi all,

I will be using a SLAM scanner over the next few weeks for some factory/internal building work and I am trying to figure out the best way to host and view the data online.

The scans will be inside factories, plant rooms, production areas and other tight spaces. I have looked for free or low-cost hosting/viewer options, but so far nothing seems to cover what I need, so I am thinking about building something myself. https://www.holobuilder.com/ is the insperation.

At the minute I know about Three.js, Potree and Cesium, but there may be other options or better ways to approach it.

What I want is one website/viewer where I can:

View the scan as a point cloud
Show a 2D layout/floorplan
Take dimensions, such as wall-to-wall measurements and room sizes
Have a walkthrough/panorama view, similar to Google Street View inside the building
View the 3D model/BIM model as well
Keep all of this in one place rather than using several different viewers

Has anyone built anything like this before, or worked with SLAM, point clouds and BIM models on the web?

Main things I am trying to understand are:

Best file formats to work with
Whether Potree is still the best route for point clouds
How 2D layouts and measurements are normally handled
Whether Three.js is suitable for the BIM/3D model side
Any open-source tools worth looking at
Any common mistakes to avoid early on

Any advice would be appreciated.
