用于360图像的A帧用户滑动效果

Question

I have a 360 Image using aframe.io library. 我有一个使用aframe.io库的360度图片。 And I would like to see how to create a "throw" effect. 我想看看如何创建“投掷”效果。 [Not sure what the effect calls] When user swipe left or right, the 360 images will rotate/spin to either direction and eventually finish after sometime (perhaps depends on how hard the swipe is?). [不确定效果如何]当用户向左或向右滑动时，360图像将旋转/旋转至任一方向，并最终在一段时间后完成（可能取决于滑动的力度？）。

I am thinking of having a a-animation within a a-sky can do the trick, but I would like to ask someone whether this is the right approach. 我正在考虑在天空中进行动画可以达到目的，但是我想问一个人这是否是正确的方法。

The effect would be similar to http://photo-sphere-viewer.js.org/ 效果类似于http://photo-sphere-viewer.js.org/

Thank. 谢谢。

 <a-sky id="vr-sky"> <a-animation attribute="rotation"></a-animation> </a-sky> <!-- Or use animation component --> <a-sky id="vr-sky" animation__rotation="property: rotation; dur: 2000; easing: easeInOut; to: 0 360 0"> </a-sky>

One way to do this is using super-hands to handle the swipe-to-throw and aframe-physics-system to handle the spinning and deceleration (with a little help from aframe-physics-extras ) 实现此目的的一种方法是使用super-hands来处理aframe-physics-system和aframe-physics-system来处理旋转和减速（在aframe-physics-extras帮助下）
