| 1 | """Example MultiPolygon Extraction with an **Unorganized* 3D Point Cloud. Step through algorithm. |
| 2 | Note this method is only suitable if you know the dominant surface normal of the plane you desire to extract. |
| 3 | The 3D point cloud must be rotated such that this surface normal is [0,0,1], i.e., the plane is aligned with the XY Plane |
| 4 | The method relies upon 3D->2D Projection and performs 2.5D Delaunay Triangulation. |
