Questions about reproducing 3DScene results: OFF preprocessing, metrics, normals, and evaluation protocol #3

Hi, thank you for releasing the code and data for SparseOcc.

I am trying to reproduce the 3DScene experiments, especially the Totempole result in Table 3. I used the author-provided 3DScene OFF files:

  • burghers.off
  • copyroom.off
  • lounge.off
  • stonewall.off
  • totempole.off

I can successfully train and evaluate the model, but my reproduced quantitative results and visual reconstruction are still different from the paper. I would like to ask for clarification about the exact 3DScene preprocessing and evaluation protocol.

My current preprocessing

Since the repository expects each scene directory to contain pointcloud.npz, I converted the provided totempole.off into pointcloud.npz by sampling points on the mesh surface.

My current conversion is roughly:

points, face_idx = trimesh.sample.sample_surface(mesh, dense_points)
normals = mesh.face_normals[face_idx]
