How to render a specific room in the 3D-FRONT dataset? From the json of 3D-FRONT, it seems that the center coordinates of each room cannot be obtained. If I want to render form a single room, how should I do it?

Describe a possible solution

Is there a way to obtain the center coordinates of each room?
