@liyihongcug I'm not completely following. What is the MBR?

This question is regarding finding the minimum-bounding-region of a model for using the region bounding volume with 3D Tiles.

In general the approach should be find the width, length, and height of the model from the accessor.min and accessor.max and convert these extents to longitude/latitude as long as the latitude is known in advance.
