# SweepNet Dataset
This repository contains three datasets used in [SweepNet](https://arxiv.org/abs/2407.06305). One dataset comprised of 20,000 sweep surfaces for neural sweeper training and two datasets used in quantitative evaluations. All datasets are preprocessed.

## Neural Sweeper Dataset
We created 20,000 sweep surface samples to train the neural sweeper, please refer to the supplementary material for the training details. 
We provided sweep surfaces with 3, 4 and 5 control points, structured as follows:
```
neuralSweeperData/
├── control_point_i/
│ ├── sweep_surface_index/
│ │ ├── parameterse.txt # sweep surface parameters
│ │ ├── bspline.ply #visualized sweeping axis
│ │ ├── sample_profile.obj #visualized profile
│ │ ├── result_sweep.ply # sweep surface
│ │ ├── manifold_points.npy # key points on the sweep surface
│ │ ├── sweep_occupancy_v1.npy # Occupancy field of the sweep surface
```

## GC-Object Dataset
We sampled 50 generalised cylinder featured objects from internet and prior works [OreX](https://arxiv.org/abs/2211.12886), [GCD](https://vcc.tech/research/2015/GCD#:~:text=Our%20decomposition%20algorithm%20progressively%20builds,on%20decomposition%20to%20global%20optimization.).
We provide processed 3D models here. Please consider cite us and the prior works if you find the dataset useful.

## Quadrupeds Dataset
We use quadrupeds dataset from [Tulsiani et al.](https://github.com/shubhtuls/volumetricPrimitives/issues/7) to benchmark SweepNet. We provide the processed data here, please cite us if you used our processed data.
