✅ 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.
