Lancet

Lancet is used for slicing Mesh, named after "柳叶刀". It is based on the Earclipping algorithm and is suitable for use during editing rather than runtime.
Lancet 用于切割 Mesh，名称取自于「柳叶刀」。它基于 Earclipping 算法实现，适合在编辑时而非运行时使用。

It has a niche application scenario: when you want to draw a Mesh yourself but don't know how to construct the Mesh's triangle indices, and your actual needs allow you to bake offline.
它有一个小众的应用场景：当你想要自己绘制一个 Mesh，但不知道怎么建构 Mesh 的三角索引，且你的实际需求允许你离线烘焙。

Examples

Vector3[] vertices;
List<int> indices;

void Refresh(){
    vertices = vertices_temp;
    indices = Triangulator.Triangulate(vertices);
}

void OnDrawGizmos() {
    if (vertices == null || vertices.Length < 3) {
        return;
    }

    // 绘制多边形边界
    Gizmos.color = Color.blue;
    for (int i = 0; i < vertices.Length; i++) {
        Gizmos.DrawLine(vertices[i], vertices[(i + 1) % vertices.Length]);
    }
}
