Inquiry on Methods to Reconstruct High-Quality Meshes from Dataset

[valyentinee]

Thank you for open-sourcing this great dataset. I am exploring its use for indoor navigation research.

I have used the provided scripts to generate 3D point clouds and then attempted mesh reconstruction (e.g., using MeshLab). But the resulting mesh quality is not satisfactory. While the overview image (dataset_overview.png) shows very complete and clean 3D scenes. Could you please share:

1. What platform, simulator, or internal pipeline was used to create those high-quality scene models in the overview?

2. Are there any recommended methods or open-source tools (e.g., specific surface reconstruction algorithms, parameters, or post-processing steps) to generate a complete, watertight mesh from the provided point clouds or depth maps?

Any guidance or pointers would be appreciated.
