Houdini数学公式应用特效教程 Hossamfx – Math in Houdini FX VOL.2 – Physical Parameters

讲解Houdini中一些常见数学公式的使用，更加高效的模拟比如破碎、碰撞、布料等特效

In this volume two of Math in Houdini FX training. We will continue exploring the big role of math in creating visual effects and controlling the simulation behavior this time we will move to more advanced concepts and provide more examples and create cool projects. I will explain one of most important physical parameter: the gradient. And show you how to use it in rigging and collision and calculation also we will go in depth with matrices and learn cool techniques using the matrix. Quaternion parameter is in our list and we will see how to create quaternion field to effect particles motion and how to use the quaternion inside the wire solver dynamics with another project. And I will show you how it to build your own cloth simulation using the Vop network and how to add gravity force, collision and pin constraints to points.

机翻：在这卷两个数学在胡迪尼FX培训。我们将继续探索数学在创建视觉效果和控制模拟行为中的重要作用，这次我们将转向更高级的概念，提供更多的示例并创建很酷的项目。我将解释一个最重要的物理参数:梯度。并向您展示如何在索具和碰撞和计算中使用它，我们也将深入研究矩阵，并使用矩阵学习很酷的技术。四元数参数在我们的列表中，我们将看到如何创建四元数场来影响粒子运动a
