I am attempting to use iTowns2 (https://github.com/iTowns/itowns2) to visualize point cloud data in the browser. According to the README: "[iTowns'] first purpose was the visualisation of street view images and terrestrial lidar point cloud."
From this I glean that there should be instances of people using iTowns to visualize point cloud data somewhere online. I've been looking for days and I can't find an example of someone using iTowns2 to visualize point cloud data in the browser.
The example in the GH repo renders a globe in the browser but no point cloud. There is a iTowns/iTowns2-sample-data repo which has a bunch of point cloud data but no instructions on how to use the data or references to other resources.
Has anyone used this package to show point cloud data in the browser? Does anyone know an article or resource that demonstrates doing this with iTowns2? Does anyone know of a different library for rendering point cloud data with examples and/or better documentation?
Ideally I would be able to track down the source code for something like this: http://www.itowns-project.org/#demo
The documentation is quite ambiguous, and judgind by the Github issues it looks like the library is under heavy refactoring.
I took a quick look to this repo and realized that it is just using Potree for point cloud visualization:
So you can just use Potree directly. Wich is better documented.
In addition to this, it's quite trivial to set up your own point cloud visualizer using Three.js.
Just take a look at the Points object:
https://threejs.org/docs/#api/objects/Points
And this example:
https://github.com/mrdoob/three.js/blob/master/examples/webgl_buffergeometry_points.html
Three.js also includes some 3D format loaders, like ply:
