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

```javascript 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： ```javascript 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。 ```javascript var _map = THREE.ImageUtils.loadTexture("../../static/3d/mtr01.jpg"); phongMtr = new THREE.MeshPhongMaterial({"color":0xffffff,"specular":0xffffff,"shininess":10,"map":_map}); ``` 错误信息： Error: WebGL: texImage2D: Conversion requires pixel reformatting. three.min.js:561:283 Error: WebGL: drawElements: bound vertex attribute buffers do not have sufficient size for given indices from the bound element array three.min.js:552:87 Error: WebGL: No further warnings will be reported for this WebGL context.
