Cesium 3dTiles 1.1 Data Conversion Method

I want to convert the OSGB format to the data format of cesium 3dtiles 1.1, but I don’t know how to convert it? Can you help me! Thank you!

There seem to be a few libraries that claim to be capable of converting OSGB to 3D Tiles (at least, judging from a quick websearch). I cannot give specific recommendations for one of these libraries. But it might be worth noting that it’s unlikely that these libraries will generate 3D Tiles 1.1 data. Most likely, the output will be 3D Tiles 1.0. One can expect that in the near future, an increasing number of conversion tools will start to actually use the features that have been introduced in 3D Tiles 1.1. Are there any specific features of 3D Tiles 1.1 that you would expect to be used by such a conversion library?
