CelloCut Benchmark

Project Page | Paper | Code

This repository contains the benchmark data and evaluation scripts used for CelloCut: Constructive Watertight Remeshing via Tetrahedral Cell Cuts. It is organized as two paired 3D mesh benchmarks: CelloFill and CelloScan.

Directory Structure

CelloCut_Benchmark/
|-- CelloFill/
|   |-- input/      # 110 input meshes, OBJ format
|   `-- gt/         # 110 ground-truth meshes, OBJ format
|-- CelloScan/
|   |-- input/      # 140 input meshes, OBJ format
|   `-- gt/         # 140 ground-truth meshes, PLY format
`-- evaluation/
    |-- geometric_metric/
    `-- visual_metric/

Files are matched by filename stem. For example, predictions for CelloScan/input/12.obj should be named 12.obj, 12.ply, or another supported mesh extension accepted by the evaluation script.

Dataset Splits

Benchmark	Input directory	Ground truth directory	Cases	Input format	Ground truth format
CelloFill	CelloFill/input	CelloFill/gt	110	OBJ	OBJ
CelloScan	CelloScan/input	CelloScan/gt	140	OBJ	PLY

Evaluation

Geometric metrics:

python evaluation/geometric_metric/evaluate_geometry.py \
  --gt-dir CelloScan/gt \
  --pred-dir path/to/predictions \
  --output-dir path/to/geometric_results

Visual metrics:

python evaluation/visual_metric/evaluate_visual.py \
  --gt-dir CelloFill/gt \
  --pred-dir path/to/predictions \
  --output-dir path/to/visual_results \
  --blender blender

See evaluation/README.md for more details on the reported metrics and optional dependencies.

Hugging Face Notes

The benchmark uses mesh files (.obj and .ply). These are distributed as repository files and are not expected to be rendered by the Hugging Face Dataset Viewer. Download the repository files directly, then run the evaluation scripts above.
