Prepare S3DIS Data

Almost all steps are the same as the mmdet3d.

Superpoint Generatation

we use SSP/SPG to generate superpoints, please see https://github.com/loicland/superpoint_graph or https://github.com/fpthink/3D-WSIS/blob/main/data/S3DIS/S3DIS.md.

Then

python tools/create_data.py s3dis --root-path ./data/s3dis --out-dir ./data/s3dis --extra-tag s3dis

The directory structure after pre-processing should be as below
