Houdini制作FEM柔体纤维和程序化运动Houdini Tutorial: FEM fibers & Procedural motion

In this tutorial I cover three mini-projects showing some of the ways you can use fiber attributes in Houdini’s FEM solver to drive soft-body motion procedurally. Assumes no prior experience with FEM. Gentle DOPs networks. Plenty of VEX, but nothing too taxing.

Hip file will be available shortly.

Sorry about all the background noise… recording in pandemic times!

在本教程中，我涵盖了三个小型项目，这些项目展示了一些您可以在Houdini的FEM求解器中使用纤维属性来以程序方式驱动软体运动的方法。假设没有使用FEM的经验。柔和的DOP网络。大量的VEX，但没有太多负担。

髋关节文件将很快可用。

对不起所有背景噪音…在大流行时期录制！
