Load a single room for 3D-FRONT dataset

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...

There an Existing Method to Organize Data by Object ID Instead of by Scene?

This might be a question to ask at https://github.com/thodan/bop_toolkit

How to map the instance information in the generated BOP dataset to the pose information one by one

Hey @Bainily028, in the coco annotations you find the `image_id` and `category_id` (=object id). In the scene_gt.json, the index should correspond the image id and you find the respective `obj_id`....

Update sensor size

Hey @TheMr33, looks good, feel free to open a pull request. However I would not add sensor size to the `set_intrinsics_from_K_matrix` function, as it does not really make sense there.

blenderproc debug crash

This is probably an issue with blender on your system. Can you run the blender standalone gui?

blenderproc debug crash

Can you try whether you can run a more recent blender version when manually downloading it? https://download.blender.org/release/Blender4.2/blender-4.2.1-linux-x64.tar.xz

blenderproc.camera.pointcloud_from_depth() return points using coordinate with the blender world as the origin instead of the camera pose.

Thanks for the hint. I agree this should be made more clear in the documentation

Memory leak when iterating scenes; bproc.clean_up() becomes progressively slower

Hey @rb4005, I cannot really reproduce your problem. When running your code, the memory increased only for about 20MB per 1000 iterations. To be fair I added the following lines...

Error with BlenderProc when using "Extra Mesh Objects" Addon

Does the addon work in blender 4.2.1 (without blenderproc)?

amodal segmentation

Hey @kamdkslansgka, yes that is possible using the bop writer. See for example here: https://github.com/DLR-RM/BlenderProc/blob/main/examples/basics/camera_object_pose/main.py#L61 The bop writer will also output masks for each object without occlusions.
