This is super challenging because of two things: one, we have to compute the elastic deformations when these millions of tiny elements collide, and two, all this, while maintaining two-way coupling.

由于以下两个原因，要做到这个超级有难度：第一，当这些上百万的细小元素碰撞时，我们必须计算出弹性形变，第二，同时还要保持双向耦合。

With this novel work, it is possible to simulate both elastic deformations as you can see here, but, it also supports simulating plasticity as you can see here with the cloth pieces sliding off of each other.

如你所见，有了这个新奇的技术，模拟弹性形变就更有希望了，而且它还同时支持模拟塑性，你看，这里的布料相互之间滑落下去。
