CMIVFX出品的另外一部全新高级教学。我们将重新带回一位广受欢迎的导师，Mehdi Salehi。这次我们将学习如何使用Houdini来开发一个sand solver。本教学没有使用HOUDINI 14中可用的Grain solver工具，而是基于FLIP OBJECT创建了一个新工具来模拟沙的效果。因此HOUDINI 13的用户也能参考本教学。通过开发与使用这个基于FLIP OBJECT的新工具，你可以拥有FLIP仿真的速度，并且通过众多参数，你可以控制flip object的行为，在渲染时获得所需的结果。此外，教学中还会为大家介绍一种将低分辨率的仿真转换为高分辨率仿真的方法。你还能在其他仿真中使用这种方法，例如POP Simulation将低分辨率仿真转换为高分辨率仿真。

Another brand new advanced Houdini video from cmiVFX! We've brought back another one of your favorite mentors, Mehdi Salehi. This time we will show you how Houdini can be used for developing a sand solver. This tutorial does not use the “Grain Solver” tool which is available in Houdini 14. Instead we will develop a new tool based on “Flip Object” to simulate sand so Houdini 13 users can also follow this tutorial. By developing and using this solver based on Flip object, you can take advantage of flip simulation speed and you will also have various parameters available so you can control the behavior of flip object and achieve the desired results in a reasonable simulation time. Moreover, in this training video we will show you an excellent method that can be used to turn a low-resolution simulation into high-resolution simulation which will also speed up your workflow. You also can use this method for other simulations like “POP simulations” to convert your low-resolution simulation to high-resolution simulation. All this and more is included in this video. Enjoy!
