# CelloCut Benchmark

[**Project Page**](https://rangeryx-66.github.io/CelloCut/) | [**Paper**](https://huggingface.co/papers/2605.17853) | [**Code**](https://github.com/rangeryx-66/CelloCut)

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

```text
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:

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

Visual metrics:

```bash
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.
