}
手势捏住是画线，展开时清除。
方案二
其他和上面一样，实现手势握拳时画线，展开时不画，再次握拳时继续画线，并且上次的线依然在。当是双手是清除线条。

第三种方案
因为通过Leap获取的点集，如何像方案2那样直接绘制，晃动会非常大。
关于晃动比较大，这个问题，我开始时把leap放在了htc上面，这样的话，leap的坐标系相当于一直在动，那坐标系里的点当然也是一直会晃动。这可以通过把leap放在桌子上，让leap的坐标系先不动来缓解，其次可以等时间来采样那些要画线的碰撞点。效果会比较好一些。还有就是碰撞物体距离手势的远近也会影响晃动的程度。物体越远，射线会把晃动的角度放大。
这儿想到，如果类似的问题里，你要评估设计方法或算法的精度，可以考虑角度的变化，因为距离越远，在夹角相同时，偏差会越大。

第五种方案
手势的碰撞器于虚拟物体碰撞且手势展开时画，不碰撞就不会，再次碰撞时继续画，这时之前画的线还在。握拳且不接触没有碰撞时在清除。其他设置同上。
关于碰撞的一些设置参考 Unity 两物体的碰撞 OnTriggerEnter和OnCollisionEnter
把手势一些关键不用的碰撞器取消，不然碰撞点的位置不会是我们希望的。
