首先创建脚本Cube
用36个顶点画Cube
private void Awake()
{

    var pMeshFilter = gameObject.AddComponent(typeof(MeshFilter)) as MeshFilter;//网格过滤器
    var pMeshRender = gameObject.AddComponent(typeof(MeshRenderer)) as MeshRenderer;//网格渲染
    var pMesh = pMeshFilter.mesh as Mesh;    //网格过滤器的实例化的Mesh

    

    Vector3[] pVector = new Vector3[36];  //顶点
    int[] pTriangles = new int[pVector.Length]; //线


    //forword
    pVector[0] = new Vector3(-0.5f, -0.5f, -0.5f);
    pVector[1] = new Vector3(-0.5f, 0.5f, -0.5f);
    pVector[2] = new Vector3(0.5f, 0.5f, -0.5f);

    pVector[3] = new Vector3(-0.5f, -0.5f, -0.5f);
    pVector[4] = new Vector3(0.5f, 0.5f, -0.5f);
    pVector[5] = new Vector3(0.5f, -0.5f, -0.5f);
    ////back
    pVector[6] = new Vector3(-0.5f, 0.5f, 0.5f);
    pVector[7] = new Vector3(-0.5f, -0.5f, 0.5f);
    pVector[8] = new Vector3(0.5f, 0.5f, 0.5f);

    pVector[9] = new Vector3(0.5f, 0.5f, 0.5f);
    pVector[10] = new Vector3(-0.5f, -0.
