## Usage

```cs
// input points for a Polygon2D contor
List<Vector2> points = new List<Vector2>();

// Add Vector2 to points
points.Add(new Vector2(-2.5f, -2.5f));
points.Add(new Vector2(2.5f, -2.5f));
points.Add(new Vector2(4.5f, 2.5f));
points.Add(new Vector2(0.5f, 4.5f));
points.Add(new Vector2(-3.5f, 2.5f));

// construct Teddy 
Teddy teddy = new Teddy(points);

Mesh mesh = teddy.Build(
    MeshSmoothingMethod.HC,  // select mesh smoothing methods : None, Laplacian, HC
    5, // count of smoothing
    0.25f, // alpha value for smoothing 
    0.5f // beta value for smoothing
);
// GetComponent<MeshFilter>().sharedMesh = mesh;
```
