THREE.js报错：THREE.Face3 is not a constructor

Question

我在自定义一个立方体，构建面的时候使用了face3，但是报错了

face3弃用了吗，好像没有，three.js的源码里也没搜到相关api，好端端的face3怎么就用不了呢
位置如下：

var faces = [
        new THREE.Face3(0, 2, 1),
        new THREE.Face3(2, 3, 1),

        new THREE.Face3(4, 5, 6),
        new THREE.Face3(6, 7, 5),

        new THREE.Face3(4, 5, 1),
        new THREE.Face3(5, 0, 1),

        new THREE.Face3(7, 6, 2),
        new THREE.Face3(6, 3, 2),

        new THREE.Face3(5, 7, 0),
        new THREE.Face3(7, 2, 0),

        new THREE.Face3(1, 3, 4),
        new THREE.Face3(3, 6, 4),
    ];
