## 使用方式

```bash
git clone --recurse-submodules https://gitee.com/kin_zhang/sdf_test
cd sdf_test
```

然后使用vscode内置的cmake_tool即可，比如[OSQP所示的GIF](https://gitee.com/kin_zhang/osqp_test/tree/master)

或者参考：how to use cmake tool to debug, follow the youtube link: https://youtu.be/Rfj40xW9q6w

## 编译运行

```bash
mkdir build
cd build
cmake ..
make
```

然后运行

```bash
./signed_distance_field_2d_test
```
