代码如下：
var xGeo = new THREE.Geometry();
xGeo.vertices.push(new THREE.Vector3(-6, 0, 0));
xGeo.vertices.push(new THREE.Vector3(6, 0, 0));
var xMat = new THREE.LineBasicMaterial({
color: 0xff0000，
linewidth: 8
});
var xAxis = new THREE.Line(xGeo, xMat);
scene.add(xAxis);
修改linewidth的值，没有任何作用，怎么解决那？

你可以换个火狐浏览器试试看

linewidth: 没用，默认为1，只有火狐貌似才可以，
