请问three.js如何提取鼠标点击选中的模型？
代码如下：
<!DOCTYPE html>
<html>
<head>
<title>测试</title>
<script type="text/javascript" src="../libs/three.js"></script>
<style>
body {
margin: 0;
overflow: hidden;
}
</style>
</head>
<body>
<div id="WebGL-output">
</div>
<script type="text/javascript">
function init() {
var scene = new THREE.Scene();
var camera = new THREE.PerspectiveCamera(45, window.innerWidth / window.innerHeight, 0.1, 1000);
var renderer = new THREE.WebGLRenderer();
renderer.setClearColor(new THREE.Color(0xEEEEEE, 1.0));
renderer.setSize(window.innerWidth, window.innerHeight);
renderer.shadowMapEnabled = true;
var planeGeometry = new THREE.PlaneGeometry(60, 20);
var planeMaterial = new THREE.MeshLambertMaterial({color: 0xffffff});
var plane = new THREE.Mesh(planeGeometry, planeMaterial);
plane.receiveShadow = true;
plane.rotation.x = -0.5 * Math.PI;
plane.position.x = 15;
plane.position.y = 0;
plane.position.z = 0;
scene.add(plane);
var cubeGeometry = new THREE.BoxGeometry(4, 4, 4);
var cubeMaterial = new THREE.MeshLambertMaterial({color: 0xff0000});
var cube = new THREE.Mesh(cubeGeometry, cubeMaterial);
cube.castShadow = true;
cube.position.x = -4;
cube.position.y = 3;
cube.position.z = 0;
scene.add(cube);
var sphereGeometry = new THREE.SphereGeometry(4, 20, 20);
var sphereMaterial = new THREE.MeshLambertMaterial({color: 0x7777ff});
var sphere = new THREE.Mesh(sphereGeometry, sphereMaterial);
sphere.position.x = 20;
sphere.position.y = 4;
sphere.position.z = 2;
sphere.castShadow = true;
scene.add(sphere);
camera.position.x = -30;
camera.position.y = 40;
camera.position.z = 30;
camera.lookAt(scene.position);
var spotLight = new THREE.SpotLight(0xffffff);
spotLight.position.set(-40, 60, -10);
spotLight.castShadow = true;
scene.add(spotLight);
document.getElementById("WebGL-output").appendChild(renderer.domElement);
renderer.render(scene, camera);
}
window.onload = init;
