THREE.js: divide a mesh to parts

Question

Is there a way to divide one THREE.Mesh into several meshes?

for example a mesh with 2000000 polygons into 2000 meshes with 1000 polygons?

Edit: I guess you can not save the exact same amount of polygons/vertices after "cutting" the original mesh, but approximation would be great as well.

就像球体爆炸成1000个迷你球体一样？ 也许在JS中编写一个函数，从场景中获取一个网格，然后以某种方式检索多边形，如果可能的话并将它们分开。然后创建一个循环，用你从数学方面得到的值创建新的网格，并删除你用过的网格

 "scene.remove( object);"

使用随机x，y，z坐标在旧网格中添加新网格
