How to get mbr of one gltf file?

I need get one MBR of one gltf file.How to get it?
(I know gltf’s coord are relatve and not geocode lon/lat)

you can use model.BoundingSphere to get the BoundingSphere of the model , and transform it to region.or, you can compute BoundingSphere by yourself,see this method : computeBoundingSphere(gltf)
