CGCircuit Applied Houdini Liquids II，我们将在这里学习如何在Houdini中使用FLIP模拟和渲染快速移动的河流的所有知识！包括学习如何设置河流的初始状态，水源和碰撞，以控制流体结果的行为，然后如何设计与之一起流动的白水！我们还将花一些时间在打湿贴图生成上，以显示打湿的碰撞体表面，在液体表面添加非模拟的细节，液滴喷涂以及其他阴影，照明和渲染策略，使其看起来尽可能更好。在此过程中，将讨论使用FLIP时可能会遇到的许多最常见的问题，尤其是在高分辨率下，以及应对它们的策略。
Applied Houdini is back for Fluids II – Rapid rivers, where we’re going to learn all about how to simulate and render a fast-moving river in FLIP! In this lesson, we’ll learn how to set up the river’s initial state, sourcing, and collisions to control the behaviour of the fluid result, and then how to design the whitewater that flows along with it! We’ll also spend time on wetmap generation in order to show wet collider surfaces, add non-simulated detail to the liquid surface, droplet sprays, and other shading, lighting, and rendering strategies to make it look as good as possible. Along the way, I’ll talk about many of the most common problems you might experience with FLIP, especially at higher resolutions. and strategies to deal with them. Altogether this is a big fun lesson that is packed with all kinds of cool techniques you’ll need to simulate and render fast moving water, so get started creating rivers today!
