PWind

Unlike PGravity, this node can create a non-uniform, turbulent force field ideal for swirling smoke and so on.

与重力不同，这个节点可以创建一个非均匀的、湍流的理想的旋转烟雾力场等。

Wind affects particles of different masses in different ways, allowing smoke-like turbulence effects. Here we’ve set things up so that the mass of a particle depends on its distance away from the origin. Just a bit of fun to see how the PWind node works! 风以不同的方式影响不同质量的颗粒，使得类似烟雾的湍流效果得以产生。在这里我们设置了一些东西，使得粒子的质量取决于它离原点的距离。看看 PWind 节点是如何工作的只是一点点乐趣
