Massive point clouds in BabylonJS

Demos and projects
1

The team here at TileDB have been putting in a lot of time to develop the capability to visualize huge point clouds (such as LiDAR). We use BabylonJS for a lot of other visualization needs and the features it has align with our needs.

The code will be open source but I am doing an early presentation on this tomorrow - https://twitter.com/tiledb/status/1592984342472663041 and it should be on youtube after that.

As mentioned elsewhere in this forum for BabylonJS a morton ordered linear octree was needed, I would like to help get this in as a feature for BabylonJS.

Hi @normanb. I’m really keen to see your presentation and experience the solution, but it doesn’t seem to be published yet on the FOSS4G UK YouTube channel?

Hi @inteja, there seems to have been some recording glitches on the day at foss4g UK, we are going to re-record and it will be uploaded shortly. Also the code and presentation will be made available.

hello, is the presentation video and code publicly available?

we are currently engaged in visualization of quarries and earth surfaces, I would really like to see an example of your code

Hi,

the code is available as is a demo site. We have two versions, one that runs in a python notebook and another that runs as a react app. Sadly the video didn’t get recorded but I did give the presentation and we made the Babylon 6 announcement video.

The point cloud (and other modalities) viewer is below and you can stream billions of points interactively;

And the Python wrapper for Jupyter is below

GitHub - TileDB-Inc/TileDB-PyBabylonJS: BabylonJS based viewer for three dimensional TileDB arrays

And finally the demo site is here https://viz.demo.tiledb.com/

Happy to discuss this more, you can reach me from our website TileDB - Beyond tables and blobs or if they are more babylonjs related questions then we can continue discussing here.
