Tracking PotreeConverter export to OGC 3D Tiles

[jo-chemla]

PotreeConverter v2 is probably the fastest pointcloud tiler I've come across. It would be great for it to support tiling a (eventually set of) pointcloud to the OGC 3D-tiles specification. Note there are already nice pointcloud tilers to 3D-tiles alternatives like mfbonfigli/gocesiumtiler and py3dtiles, although lowest throughput of M-points-per-second.

There are also single-file OGC 3D-tiles tilesets standard formats, akin to the v2 vs v1 potree format - quick discussion about .3dtiles vs .3tz here NASA-AMMOS/3DTilesRendererJS#722

Previous OGC 3D-tiles versions stored tiles as custom pnts tile files (~glTF wrapper), but version 1.1 of the specification simply stores them as glTF POINTS primitive mode. Compression is made available by using glTF KHR khronos extensions - like presented by Cesium team in this thread about 3D gaussian-splats, like EXT_mesh_quantization + EXT_meshopt_compression

I'm opening this issue thread to gauge whether this would be a direction you'd be interested in, as well as tracking interest by the community. Eventually someone could tackle that challenge.
