# Mesh Untangling Benchmark
This repository contains the publicly redistributable portion of the benchmark
used by [Mesh Untangling](https://github.com/AppledoreM/untangling-research).
It contains 166 input meshes:
| Dataset | Cases | Files | License |
| --- | ---: | --- | --- |
| Analytic Surfaces (`math`) | 26 | OBJ | Apache-2.0 |
| Microsoft Rocketbox | 140 | OBJ and companion MTL | MIT |
These are benchmark inputs and may contain self-intersections. They are not
solver outputs.
ISIR, SMAL, and SCAPE are not included because their distribution terms require
users to obtain the data from the respective owners.
## Layout

SHA256SUMS
```
`metadata/included-cases.json` records the 166 canonical OBJ paths and hashes.
`SHA256SUMS` covers every distributed OBJ and MTL file.
## Download and run
Install the Hugging Face CLI if needed with
`python3 -m pip install --upgrade huggingface_hub`. From the Mesh Untangling
repository root, run:
```bash
hf download AppledoreM/Mesh-Untangling-Benchmark \
--repo-type dataset \
--local-dir benchmark-data
python3 scripts/run_untangle_benchmark.py \
--data-root benchmark-data/data \
--output-root output/public-benchmark \
--forward-flow-binary build/bin/Release/mesh-untangle \
--reverse-flow-binary build/bin/Release/reverse-flow \
--case 'math/*' \
--case 'Microsoft-Rocketbox/*'
```
Run from the Mesh Untangling repository root, keep the case globs quoted, and
choose an output directory that does not already exist.
## Integrity
From the downloaded repository root:
```bash
sha256sum --check SHA256SUMS
```
## Licensing and provenance
The Analytic Surfaces meshes are released under Apache-2.0. The selected
Microsoft Rocketbox assets and their derived benchmark exports retain
