Access the Matlab file in other sources: No, we haven't tried it in other programs/libraries. Bbox data: This information is not contained elsewhere, however, as you pointed out, you can easily compute them by finding the min-max values per axis for each object. If you prefer to work on point clouds, you can find the corresponding data at the Stanford Large-Scale 3D Indoor Spaces Dataset (S3DIS) (description, download link).
Thank you very much for providing the dataset.
I am currently trying to access the data in the pointcloud.mat . Unfortunately I don't have access to matlab so I tried to open it with some HDF5 libraries with python but somehow I just got strange references, but no clear data structure (as can be seen in the screenshot in issue #14). Therefore my first question is if you used besides Matlab another program/Library to access the pointlcoud.mat file ?
As I am especially highly interested in the BBox data for the 3D point cloud I would also be interested if it is accessible also at another place (in the only 3D dataset I didn't find it) ?
Last question : The BBox parameter are estimated by looking at the pointcloud of the object and searching for the min/max values of this pointcloud for the different coordinates ?
