需要引用文件 renderers/Projector.js
在raycaster.intersectObjects()中写要监听的物体
调用 document.addEventListener('mousedown', getClickMap, false);
var projector=new THREE.Projector();
var i=1;
function getClickMap(){
var vector=new THREE.Vector3((event.clientX/window.innerWidth)*2-1,-(event.clientY/window.innerHeight)*2+1,0.5);
vector=vector.unproject(camera);
var raycaster=new THREE.Raycaster(camera.position,vector.sub(camera.position).normalize());
var intersects=raycaster.intersectObjects([cube]);
if(intersects.length>0){
console.log(intersects[0]);
intersects[0].object.material.transparent=true;
intersects[0].object.material.opacity=1*i;
intersects[0].object.material.color=new THREE.Color(0xededed);
intersects[0].object.scale.x=2*i;
}
