如何在three.js中获得立方体所有角的精确x，y，z位置

var geometry = new THREE.BoxGeometry(width, height, depth);
var material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
var cube = new THREE.Mesh(geometry, material);
scene.add(cube);

var position = new THREE.Vector3();
var quaternion = new THREE.Quaternion();
var scale = new THREE.Vector3();

cube.matrixWorld.decompose(position, quaternion, scale);

var vertices = cube.geometry.vertices;

for (var i = 0; i < vertices.length; i++) {
    // 将顶点坐标从局部坐标系转换为世界坐标系
    var vertex = vertices[i].clone();
    vertex.applyMatrix4(cube.matrixWorld);

    // 获取顶点的x、y、z位置
    var x = vertex.x;
    var y = vertex.y;
    var z = vertex.z;

    console.log("顶点" + i + "的位置：x=" + x + "，y=" + y + "，z=" + z);
}
