我刚刚了解到THREE.js，并且对它的能力着迷。我没有先进到足够写我自己的代码，所以我一直在浏览试图找到一个例子来做到我需要或接近，但到目前为止没有用：:(three.js网格倾斜而不是旋转
我正在使用的是一些。代码，用鼠标移动的物体的X轴工作prefectly但Y轴周围的物体旋转，倾斜，而不是它的左右
我当前的代码：
var container, stats;
var camera, scene, renderer;
var group, text, plane;
var targetRotationX = 0;
var targetRotationOnMouseDownX = 0;
var targetRotationY = 0;
var targetRotationOnMouseDownY = 0;
var mouseX = 0;
var mouseXOnMouseDown = 0;
var mouseY = 0;
var mouseYOnMouseDown = 0;
var windowHalfX = window.innerWidth/2;
var windowHalfY = window.innerHeight/2;
var finalRotationY
var center
init();
animate();
function init() {
camera = new THREE.PerspectiveCamera(100, window.innerWidth/window.innerHeight, 0.1, 10000);
camera.position.z = 1000;
camera.eulerOrder = "YXZ"
scene = new THREE.Scene();
// lights
light = new THREE.DirectionalLight(0xffffff);
light.position.set(1, 1, 1);
scene.add(light);
light = new THREE.DirectionalLight(0x002288);
light.position.set(-1, -1, -1);
scene.add(light);
light = new THREE.AmbientLight(0x222222);
scene.add(light);

\t \t var cube = new THREE.Mesh(geometry, material);
\t \t //cube.position.set(center.x, center.y, center.z);
\t \t //cube.geometry.applyMatrix(new THREE.Matrix4().makeTranslation(-center.x, -center.y, -center.z));

<div id="container"></div>我希望做的事情是，当鼠标被点击并向左或向右移动时，除非鼠标向上或向下移动，否则盒子将向着鼠标倾斜并保持相同的“X”旋转。现在，相机似乎围绕对象旋转，而不是沿相应的方向倾斜。
任何想法？

我不是100％确定要问什么，所以我只是留下评论而不是答案。当鼠标向左或向右移动时，我认为你想要做的是围绕Z轴而不是Y轴旋转......？ – micnil
