我刚刚了解了THREE.js，并对它的能力着迷。我没有足够的高级编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我所需要的或接近，但到目前为止无济于事（
我正在使用的是一些使用鼠标移动对象的代码。 X轴完美地工作，但Y轴围绕物体旋转而不是左右倾斜。
我目前的代码：
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.position.set( -1, -1, -1 );
scene.add( light );
light = new THREE.AmbientLight( 0x222222 );
scene.add( light );
var geometry = new THREE.BoxGeometry(1400, 100, 700, 10, 10, 10);
var material = new THREE.MeshBasicMaterial({color: 0xfffff, wireframe: true});
var cube = new THREE.Mesh(geometry, material);
//cube.position.set( center.x, center.y, center.z );
//cube.geometry.applyMatrix(new THREE.Matrix4().makeTranslation( -center.x, -center.y, -center.z ) );

我希望做的是当点击鼠标并向左或向右移动时，盒子将朝向鼠标倾斜并保持相同的状态＆＃34; X＆＃34;旋转，除非鼠标也向上或向下移动。现在，相机似乎围绕物体旋转，而不是在相应的方向上倾斜。
有什么想法吗？

micnil是对的，我不得不将旋转顺序更改为“ZYX”。现在开始学习如何将我的2个脚本连接在一起。
