THREE.js 为new THREE.Geometry()添加带有map纹理的材质时报错

                        var geo=new THREE.Geometry();
                    for(var i=0;i<_vertex.length;i++){
                        var _n=_vertex[i]; //_vertex顶点数组：[[x1,y1,z1],[x2,y2,z2]...]
                        geo.vertices.push(new THREE.Vector3(_n[0],_n[1],_n[2]));
                    }
                    for(var i=0;i<_faces.length;i++){
                        var _n=_faces[i]; //_faces面数组[[1,2,3]，[4,5,6]]
                        geo.faces.push(new THREE.Face3(_n[0],_n[1],_n[2]));
                    }
                    geo.computeFaceNormals();
                    geo.computeVertexNormals();
                    geo.computeBoundingSphere();
                    var mesh=new THREE.Mesh(geo,phongMtr);

当phongMtr不含有纹理贴图时，则没有问题：

phongMtr = new THREE.MeshPhongMaterial({"color":0xffffff,"specular":0xffffff,"shininess":10});

一旦引入纹理贴图，即下段代码，就会报错。

var _map = THREE.ImageUtils.loadTexture("../../static/3d/mtr01.jpg");
phongMtr = new THREE.MeshPhongMaterial({"color":0xffffff,"specular":0xffffff,"shininess":10,"map":_map});
