Orbit Controls 跟隨鼠標不點擊three.js

Question

有沒有人有代碼可以強制three.js 中的軌道控件在mousemove 上移動場景而不是click + mousemove 我試過使用這個線程中的答案： 如何在鼠標移動時重新創建Three.js OrbitControl 移動？ 但遺憾的是它拋出一個錯誤“最大調用堆棧大小超出錯誤”，我只得到一個黑色畫布，里面什么都沒有......

我也試過改變

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

到

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

在 OrbitControls.js 文件中，但它似乎在移動和時不時停止時凍結......

有沒有人設法解決這個問題？ 提前致謝！

這個怎么樣; 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 );

使用一個 Object3D 作為相機的樞軸。 它隨着鼠標移動而旋轉。
