# RGBench Cloth Sim-to-Real (v1)
🌐 Project page: <https://rgbench.github.io/> · 📦 Code: <https://github.com/hwk0809/RGBench>
Nine carefully captured garments — three bimanual manipulation actions
each (fling / fold / grasp) — with **real-world ground truth point
clouds** for evaluating any cloth simulator's sim-to-real gap. Released
as the evaluation half of the AAAI 2026 paper *[Real Garment Benchmark
(RGBench)](https://rgbench.github.io/)*.
The larger 6 000+ garment-mesh asset library and the GarmentDynamics
simulator from the paper are on their way to open-sourcing in follow-up
releases. This dataset is the piece you need to **benchmark any cloth
simulator against real captured dynamics today**.

9 garments × {grasp, fold, fling} actions, captured with a Piper bimanual
gripper and a RealSense D455. ~100 evaluation samples in total. Two
garments (`grey_sunwear`, `khaki_blazer`) have non-manifold meshes and
are **not** part of the paper's published baselines — see the
[results/](https://github.com/hwk0809/RGBench/tree/main/results) folder
in the GitHub repo for the published baseline numbers and the
methodology note.
Garment meshes ship in four resolutions for `green_tshirt` (5k / 10k /
20k / 40k triangles) under `meshes/Green_Tshirt_Compare/` so researchers
can study how cloth mesh resolution affects sim-to-real fidelity.
## Quickstart
```bash
git clone https://github.com/hwk0809/RGBench
cd RGBench
bash setup.sh # installs deps + downloads this dataset
make benchmark sim=pybullet # runs the smoke-test sample
```
If you only want to fetch the data:
```bash
pip install huggingface_hub
python -m huggingface_hub.commands.huggingface_cli download \
hwk0809/RGBench-Cloth-Sim2Real-v1 --repo-type dataset \
--local-dir ./data/sample
```
