The Gnomon Workshop – Introduction To The Houdini Ocean Toolset

创建大型海洋模拟并不需要艰巨。由丹尼·巴恩哈特（Danny Barnhart）进行的为时3.5小时的入门讲习班概述了Houdini的海洋工具集，并揭示了如何使自己的海洋环境变得生动。他讲解了使用海洋光谱的基础知识，以及每个参数如何与生成的动画海洋表面相关联，首先创建了一个大型海洋表面，以展示如何对各种光谱图案进行分层，以及如何创建自定义蒙版和实例波。一旦实现了所需的海洋运动，Danny就开始研究简单的环境几何形状，从而在研究模拟表面泡沫之前增加场景的趣味性和比例。

接下来的项目拍摄了广阔的海洋场景，并转换为包含FLIP流体模拟的特写镜头。您将发现如何引入海洋光谱并创建自定义波浪来驱动FLIP模拟。一旦FLIP模拟被缓存，Danny将讨论如何对模拟进行网格化和扩展，以及如何为最终效果创建额外的海洋喷雾。作为最后一步，您将看到如何在Houdini中设置一些基本照明并调整海洋着色器，以在Houdini的渲染引擎Mantra中渲染两个项目场景。

通过完成该视频教程，您将对Houdini海洋工具集有全面的了解，并了解如何自定义海洋光谱以为您的未来项目创建各种海洋运动。

该研讨会提供了项目文件，包括Houdini场景文件以及每个课程的最终节点设置，以及用于创建场景的棕榈树模型。

Title: The Gnomon Workshop – Introduction To The Houdini Ocean Toolset
Info:
Creating a large ocean simulation doesn’t need to be daunting. This 3.5-hour introductory workshop by Danny Barnhart provides an overview of the Ocean Toolset in Houdini and reveals how to bring your own ocean environments to life. He talks through the basics of using ocean spectrums and how each parameter relates to the resulting animated ocean surface, beginning by creating a large ocean surface to show how to layer a variety of spectrum patterns as well as how to create custom masks and instanced waves. Once the desired ocean movement is achieved, Danny starts incorporating simple environment geometry to add interest and scale to the scene before delving into simulating surface foam.

The following project takes the large ocean scene and transitions to a close-up shot that incorporates a FLIP fluid simulation. You’ll discover how to bring in your ocean spectrums and create custom waves to drive your FLIP simulation. Once the FLIP simulation is cached out, Danny discusses how to mesh and extend the simulation, as well as how to create additional ocean spray for the final effect. As the last step, you’ll see how to set up some basic lighting and tweak the ocean shaders in Houdini to render out the two project scenes in Mantra, Houdini’s rendering engine.

By completing this workshop, you’ll have a sound knowledge of the Houdini Ocean Toolset and an understanding of how to customize ocean spectra to create a variety of ocean movements for your future projects.

Project files are available with this workshop, including the Houdini scene file with the final node setup for each lesson, along with the palm tree model used in the creation of the scene.
