Masks for downsampling ScanNet++ V1 GS

The masks are for downsampling the Gaussian .npy files of GaussianWorld/scannetpp_v1_mcmc_3dgs_preprocessed.

The masks are created with /data/downsample_pc.py

  1. Download GaussianWorld/scannetpp_v1_mcmc_3dgs_preprocessed in /work/$USER - only train and val split
  2. Download the masks here (amhalacheva/spp_v1_downsampled_gs)
  3. Apply the masks on the .npys from scannetpp_v1_mcmc_3dgs_preprocessed
  4. Rename /work/$USER/scannetpp_v1_mcmc_3dgs_preprocessed to /work/$USER/scannetpp_v1_mcmc_3dgs_preprocessed_downsampled as this is scan path in config for training.
