1，可以直接使用自带的案例完成leap的手势交互。
copy
2, 手势的抓取不是很稳定，可以通过修改抓取的交互代码改进。
A 当手指的外置与物体的距离小于一定值时，将要抓取的物体变为手指的子物体。
-------直接将手指的position赋给要交互的物体。
--------或者把其变为手指的子物体，但没有上面简单。
------------手指的位置获取，可以通过代码也可以通过拖动某一个手指的关节。
B 当物体到达要完成装配的目的的时，直接把目的地的位置赋给交互的零件。防止安装完成后零件又粘连在手指上，当到达目的地后同时把交互的脚本不打勾。

可以让物体与手势相碰撞时让零件变为绿色，要修改 primary hover color
