# Positon based dynamic with taichi

- The code implements one of nvidia's paper [PBD](https://mmacklin.com/uppfrta_preprint.pdf)

- The code uses [Taichi](https://github.com/taichi-dev/taichi) programming language

- Second you need to install dependency
```python
pip install -r requirements.txt
```

- Last you type
```python
ti Example.py
```

## How to generate voxel file

- First copy your obj file to "model" , for example "Bearings.obj"

- Second you need to modify the code in GenVoxel.py
```python
obj_name = "Bearings"
```

- Then you type
```python
ti GenVoxel.py
```

- Last you will get a voxel file like below:
