CGCircuit – Houdini Essentials: Large Scale Fluids

在这个 Houdini Essential 系列中，我们将看看 Houdini 中的一些先进的 Flip Fluid 技术，以创建大规模的水溅。

我们将剖析翻转求解器的各种参数，例如液滴、窄带和阻力场，以控制模拟的规模。我们将构建几何的自定义 VDB，以实现准确的碰撞。然后我们将有效地使用新的白水系统并讨论驱虫剂、侵蚀、密度控制等来控制和创建我们的泡沫元素。
接下来是查看网格划分工作流程，我们将使用一些自定义平滑技术并讨论展平我们的网格。
本课程专为中级到高级 Houdini 用户设计。即使我们将创建从组开始的所有内容，但总体上仍需要 DOP 和 Flip Fluids 的基本知识。

完成本课程后，艺术家将非常熟悉 Houdini 中翻转求解器的内部工作原理，从而能够轻松创建戏剧性的白水和大规模飞溅效果。

使用的工具：Houdini、Houdini 18

先决条件：有基础的Houdini知识

Title: CGCircuit – Houdini Essentials: Large Scale Fluids

Info:
In this Houdini Essential series, we are going to take a look at some advanced Flip Fluid techniques in Houdini to create a large scale water splash.

We will dissect various parameters of the flip solver such as droplets, narrow banding and drag fields to control the scale of our simulation. We will construct custom VDBs of our geometry for accurate collisions. We then will effectively use the new white water system and talk about repellents, erosion, density controls, etc to control and create our foam elements.
This is followed by taking a look at the meshing workflow where we will use some custom smoothing techniques and talk about flattening our mesh.
This course has been designed for intermediate to advanced Houdini users. A basic knowledge of DOPs and Flip Fluids in general is needed even though we will be creating everything from the group up.

Upon finishing this course, an artist will be very familiar with the inner workings of flip solver in Houdini so as to be able to create dramatic whitewater and large scale splash effects with ease.
