Since my withdrawal symptoms are already kicking in, today, I simply have to talk to you about this amazing paint simulator program that runs in real time and on our mobile devices.

鉴于我的拖延症已经开始发作了，今天我必须得跟你们讲讲这个令人激动的绘画模拟器，它能够在移动设备上达到实时渲染的效果。

With a large-scale simulator, this would take a stupendously large amount of time and resources, so the key observation is that a small-scale fluid simulator program would be introduced to take care of this.

因为大规模模拟需要耗费大量的时间和资源，所以 关键是将小规模流体模拟程序引入进来。
