我有一个使用threejs创建的地球仪。我正在使用轨道控制使其可拖动。我的问题是在触摸设备上拖动不能正常工作。在边缘你根本无法拖动它，在Firefox上你可以水平拖动它但是如果你垂直拖动它会向下滚动而不是拖动。如何允许在移动设备上拖动？
这是我的orbitcontrols代码：
this._controls = new THREE.OrbitControls(this._camera, this._renderer.domElement);
this._controls.rotateSpeed = .08;
this._controls.zoomSpeed = 1.0;
this._controls.enableZoom = false;
this._controls.enablePan = false;
this._controls.enableDamping = true;
this._controls.minDistance = 23.0;
this._controls.maxDistance = 70.0;
this._controls.dampingFactor = 0.1;

问题是渲染的DOM元素<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

您是否考虑使用Hammer.js等触摸事件助手？它的主要用途是手势，但我成功地使用了Hammer来解决与简单触摸交互相关的兼容性问题。
