Load a single room for 3D-FRONT dataset

[ruili3]

Describe your feature request

Thanks for the awesome library! I want to load only one room rather than a whole house when rendering each scene of the 3D-FRONT dataset and then saving the single room's structure into a ".obj" file. Is there any solution for this?

Thank you very much!

This is currently not implemented in BlenderProc, however it should be possible by slightly adjusting the Front3DLoader. The furniture objects are already loaded room-by-room: https://github.com/DLR-RM/BlenderProc/blob/main/blenderproc/python/loader/Front3DLoader.py#L407 So here you just need to do only one iteration for the room you want to load.
For the walls and ceilings its a bit more difficult. Here you would need to first match them with their data["scene"]["room"]["children"] entry and then only create the ones from the selected room https://github.com/DLR-RM/BlenderProc/blob/main/blenderproc/python/loader/Front3DLoader.py#L52
