Store a pointcloud 3D tileset to a sqlite databse

I have created a tileset from a LAS point cloud. It contains a main Data folder with many subfolders and a tileset.json descriptor file. The pointcloud data is stored in .pnts files.

I can load and display this data using cesium.js.

My pointcloud has about 53M points and it results in a 970MB folder structure with ~21k files.

For better performance and portability, I would like to store my tileset in a .3dtiles file (which is an sqlite database), just like Cesium Ion stores it.

Are there some tools available to do this conversion?
