✅ Answer
Coordinate System
3D tiles format has a coordinate system based on WGS84, which is the standard for GPS systems.
WGS84 is a right-handed coordinate system that uses the Earth’s center mass as the coordinate origin, so it does not have a definite up direction since that depends on where the coordinate is within the system.
Conversion to other formats
Since 3D tiles is based on gltf format, Sean Lilley gave an example how coordinates are transformed from gltf coordinates to WGS84 coordinate system in SIGGRAPH 2023.
