THREE.js相交[0] .object.position總是返回（0,0,0）

Question

我正在使用THREE.js在我的頁面上顯示一些對象。我可以點擊對象，但我注意到無論點擊哪個對象，intersects[0].object.position總是返回x=0, y=0, z=0，而對象的實際位置無疑是不同的。

您可以查看下面的代碼並發表評論我做錯了什麼？

function onDocumentMouseDown(event) { 
    event.preventDefault(); 
    var vector = new THREE.Vector3((event.clientX/window.innerWidth)*2-1, -(event.clientY/window.innerHeight)*2+1, 0.5); 
    projector.unprojectVector(vector, camera); 
    var ray = new THREE.Ray(camera.position, vector.subSelf(camera.position).normalize()); 
    var intersects = ray.intersectObjects(teeth, true); 
    if (intersects.length > 0) { 
    //not working 
    camera.position.x=intersects[0].object.position.x; 
    //not working 
    camera.position.y=intersects[0].object.postion.y; 
    //working 
    intersects[0].object.material.color.setHex(Math.random()*0xffffff); 
    } 
} 

Answer 1

的對象的位置是：相交[0] .object.position

的相交位置：相交[0] .POSITION

function onDocumentMouseDown(event) { 
    event.preventDefault(); 
    var vector = new THREE.Vector3((event.clientX/window.innerWidth)*2-1, -(event.clientY/window.innerHeight)*2+1, 0.5); 
    projector.unprojectVector(vector, camera); 
    var ray = new THREE.Ray(camera.position, vector.subSelf(camera.position).normalize()); 
    var intersects = ray.intersectObjects(teeth, true); 
    if (intersects.length > 0) { 
    //not working 
    camera.position.x=intersects[0].point.x; 
    //not working 
    camera.position.y=intersects[0].point.y; 
    //working 
    intersects[0].object.material.color.setHex(Math.random()*0xffffff); 
    } 
}
