RhinoCommon 使用点(点云)构建Mesh

如何使用RhinoCommon 使用点(点云)构建Mesh，以下为参考代码

   public static Rhino.Commands.Result AddMesh(Rhino.RhinoDoc doc)
    {
        Rhino.Geometry.Mesh mesh = new Rhino.Geometry.Mesh();
        mesh.Vertices.Add(0.0, 0.0, 1.0); //0
        mesh.Vertices.Add(1.0, 0.0, 1.0); //1
        mesh.Vertices.Add(2.0, 0.0, 1.0); //2
        mesh.Vertices.Add(3.0, 0.0, 0.0); //3
        mesh.Vertices.Add(0.0, 1.0, 1.0); //4
        mesh.Vertices.Add(1.0, 1.0, 2.0); //5
        mesh.Vertices.Add(2.0, 1.0, 1.0); //6
        mesh.Vertices.Add(3.0, 1.0, 0.0); //7
        mesh.Vertices.Add(0.0, 2.0, 1.0); //8
        mesh.Vertices.Add(1.0, 2.0, 1.0); //9
        mesh.Vertices.Add(2.0, 2.0, 1.0); //10
        mesh.Vertices.Add(3.0, 2.0, 1.0); //11

        mesh.Faces.AddFace(0, 1, 5, 4);
        mesh.Faces.AddFace(1, 2, 6, 5);
        mesh.Faces.AddFace(2, 3, 7, 6);
        mesh.Faces.AddFace(4, 5, 9, 8);
        mesh.Faces.AddFace(5, 6, 10, 9);
        mesh.Faces.AddFace(6, 7, 11, 10);
        mesh.Normals.ComputeNormals();
        mesh.Compact();
        if (doc.Objects.AddMesh(mesh) != Guid.Empty)
        {
          doc.Views.Redraw();
          return Rhino.Commands.Result.Success;
        }
        return Rhino.Commands.Result.Failure;
    }

以上代码生成的mesh，各个面都是四边形；若要生成三边形，请参考以下代码：

import rhinoscriptsyntax as rs

vertices = []
vertices.append((0.0,0.0,0.0))
vertices.append((5.0, 0.0, 0.0))
vertices.append((10.0, 0.0, 0.0))
vertices.append((0.0, 5.0, 0.0))
vertices.append((5.0, 5.0, 0.0))
vertices.append((10.0, 5.0, 0.0))
vertices.append((0.0, 10.0, 0.0))
vertices.append((5.0, 10.0, 0.0))
vertices.append((10.0, 10.0, 0.0))

faceVertices = []
faceVertices.append((0,1,4,4))
faceVertices.append((2,4,1,1))
faceVertices.append((0,4,3,3))
faceVertices.append((2,5,4,4))
faceVertices.append((3,4,6,6))
faceVertices.append((5,8,4,4))
faceVertices.append((6,4,7,7))
faceVertices.append((8,7,4,4))

rs.AddMesh( vertices, faceVertices )
