Scene Graphs and Full-Scene Reconstruction from Regions

[BigTree765]

Thank you for your excellent work!

I have two quick questions:

1 Scene graphs for indoor objects: Would it be possible to provide scene graphs of objects within the house?

2 Reconstructing full scenes from regions: Currently, large scenes are stored per region (e.g., individual rooms). Is there a way to reconstruct the original full scene—i.e., combine multiple regions/rooms—while also preserving or recovering the room category labels (e.g., kitchen, bedroom, etc.)?

Thanks in advance for your help!

Thank you for your interest and kind words! Regarding your questions:

Scene Graphs: Currently, our repository does not provide pre-computed scene graphs. If your research requires scene graphs, we recommend implementing custom rules tailored to your specific task (e.g., spatial proximity or functional relationships).

Full Scene Reconstruction: The InternScenes-Real2Sim subset is built upon real scan datasets including ScanNet, MP3D, ARKitScenes, and 3RScan. To facilitate efficient construction, our dataset focuses on region-level layouts. For reconstructing a complete house with multiple rooms, we suggest referring to the original metadata and alignment tools provided by the source datasets like ScanNet or Matterport3D.

Hope this helps!
