Three.js获取鼠标点击的三维坐标示例代码

function onDocumentMouseDown( event ) {  event.preventDefault();  var vector = new THREE.Vector3();//三维坐标对象  vector.set(    ( event.clientX / window.innerWidth ) * 2 - 1,    - ( event.clientY / window.innerHeight ) * 2 + 1,    0.5 );  vector.unproject( camera );  var raycaster = new THREE.Raycaster(camera.position, vector.sub(camera.position).normalize());  var intersects = raycaster.intersectObjects(scene.children);  if (intersects.length > 0) {    var selected = intersects[0];//取第一个物体    console.log("x坐标:"+selected.point.x);    console.log("y坐标:"+selected.point.y);    console.log("z坐标:"+selected.point.z);  }
