自定义的曲线力场工具Houdini – Follow curve with twist and attraction/repulsion

A Houdini smoke sim setup with parameters for radius, strength, and falloff curves for twisting and attraction/repulsion to a curve. This is different from the curve force DOP node, I wrote it from scratch.
Houdini烟雾模拟设置，具有半径，强度和衰减曲线的参数，用于扭曲和吸引/排斥曲线。这与曲线力DOP节点不同，我是从头开始编写的。
