My Question

I need to label my point clouds to perform semantic segmentation afterwards on them. From my understanding Open3D provides all functionalities select parts of point clouds, right?

I searched the examples and also took a look at Open3D-ML but couldn't find a fitting example where I can apply labels to my point cloud.

If there really isn't an example yet, I would start working on it and maybe open a PR afterwards. In case I'm missing sth here, e.g. that Open3D does not provide the needed functionalities such as polygon selection etc. or such a labeling tool based on Open3D already exists, please let me know.
