Houdini引导动力学Guided Dynamics in Houdini

Guided Dynamics in Houdini – Part 1

We will be using the Damped Harmonic Oscillator formula to create some pseudo spring constraints, we will go through the initial details on this video, and set up the position targeting.

我们将使用阻尼谐波振荡器公式来创建一些伪弹簧约束，我们将介绍本视频的初始细节，并设置定位目标。

Guided Dynamics in Houdini – Part 2

On this video we will start talking about the rotation, from here it get’s a bit more tricky, we will talk a bit about primitive intrinsic attributes, matrices, order of operations, and the difference Matrix.

在这个视频中，我们将开始讨论旋转，从这里开始有点棘手，我们将讨论一些原始内在属性、矩阵、运算顺序和差分矩阵。

Guided Dynamics in Houdini – Part 3

On this video we will finish the Matrix implementation of the rotation follow, we will talk about the cracktransform function, and will use the Damped Harmonic Oscillator formula to drive the angular velocity.

在本视频中，我们将完成旋转跟随的矩阵实现，我们将讨论裂纹变换函数，并将使用阻尼谐波振荡器公式来驱动角速度。

Guided Dynamics in Houdini – Part 4. link to file in the Description

On this final video we will create an additional option for the rotation follow system, this time using quaternions rather than matrices, additionally we will create a function for dot products between quaternions so we can compare them, and at the very end we will test our system with many more points to check that everything is working.

在这个最后的视频中，我们将为旋转跟随系统创建一个附加选项，这次使用四元数而不是矩阵，另外我们将为四元数之间的点积创建一个函数，以便我们可以比较它们，最后我们将测试我们的系统有更多的点来检查一切是否正常。
