Orbit Controls 跟随鼠标不点击three.js

Question

有没有人有代码可以强制three.js 中的轨道控件在mousemove 上移动场景而不是click + mousemove 我试过使用这个线程中的答案： 如何在鼠标移动时重新创建Three.js OrbitControl 移动？ 但遗憾的是它抛出一个错误“最大调用堆栈大小超出错误”，我只得到一个黑色画布，里面什么都没有......

我也试过改变

scope.domElement.addEventListener( 'mousedown', onMouseDown, false );

到

scope.domElement.addEventListener( 'mousemove', onMouseDown, false );

在 OrbitControls.js 文件中，但它似乎在移动和时不时停止时冻结......

有没有人设法解决这个问题？ 提前致谢！

这个怎么样; https://jsfiddle.net/EthanHermsey/e3b501cw/51/

document.addEventListener('mousemove', function(e){
    let scale = -0.01;
    orbit.rotateY( e.movementX * scale );
    orbit.rotateX( e.movementY * scale ); 
    orbit.rotation.z = 0; //this is important to keep the camera level..
})

//the camera rotation pivot
orbit = new THREE.Object3D();
orbit.rotation.order = "YXZ"; //this is important to keep level, so Z should be the last axis to rotate in order...
orbit.position.copy( mesh.position );
scene.add(orbit );

//offset the camera and add it to the pivot
//you could adapt the code so that you can 'zoom' by changing the z value in camera.position in a mousewheel event..
let cameraDistance = 1;
camera.position.z = cameraDistance;
orbit.add( camera );

使用一个 Object3D 作为相机的枢轴。 它随着鼠标移动而旋转。
