Houdini控制涡流状粒子形态Guest Tutorial: Simon Fiedler – Controlling Swirly Particles

It finally happened – our dear friend Simon Fiedler (https://simonfiedler.de/) agreed to record a guest tutorial for us.

He decided to share one of his production tricks for controlling particles: Building a swirly vector field to advect particles. Although it looks organic and natural, it’s highly controllable using a few basic vector math hacks. Enjoy!

It finally happened – our dear friend Simon Fiedler (https://simonfiedler.de/) agreed to record a guest tutorial for us.

他决定分享他控制粒子的生产技巧之一：建立涡旋矢量场以平移粒子。尽管它看起来很自然自然，但是可以使用一些基本的矢量数学技巧进行高度控制。请享用！
