CG Circuit – Introduction to VEX – Volume 2

本课程重点介绍 VEX 在两个最常见的 VFX 任务（粒子和体积）中的使用。
虽然这是一门介绍课程，但它通过使用属性 VOP 和 Wrangles 教授了非常有用和强大的脚本的实现。

它以这样一种方式设计，让观众以一种非常实用的方式逐渐学习，可以在许多实际情况下使用许多常见的 VEX 功能。

在第一章中，我们将解释如何在任何一种模拟中控制两个基本概念；速度和力，带有简单的 VEX 片段。我们还将解释如何控制粒子外观的基本方面，如大小、颜色和不透明度。在第二章中，我们将学习从头开始用密度填充体积，然后“雕刻”体积的密度以创建相对复杂的形状，如云和涡流，而无需模拟。

本课程专为寻求专注于 VFX 的初级 3D 艺术家或具有其他 3D 应用程序背景的艺术家而设计，他们希望了解 Houdini for VFX。它的设计方式即使是全新的 Houdini 用户也可以轻松掌握主要的 VEX 概念并在很短的时间内开始创建自己的效果。
看过本课程后，人们可以期待能够自信地开始编写 VEX 表达式和代码片段来控制粒子系统和体积的创建和修改。

Title: CG Circuit – Introduction to VEX – Volume 2

Info:
This course focuses on the use of VEX applied in two of the most common VFX tasks, Particles, and Volumes.
Although it is an introduction course, it teaches the implementation of very useful and powerful scripting, through the use of attribute VOPs and Wrangles.

It is designed in such a way that the viewer will learn gradually and in a very practical way, the use of many common VEX functions that can be used in many real situations.

In the first chapter, we will explain how to control two fundamental concepts in any kind of simulation; velocity and forces, with simple VEX snippets. We will also explain how to control basic aspects of the particles’ appearance like size, color, and opacity. In the second chapter, we will learn to populate volumes with density from scratch and then “sculpt” the volume’s density to create relative complex shapes like clouds and vortices without the need for simulations.

This course has been designed for beginner level 3D artists seeking to specialize in VFX or artists with a background in other 3D applications wanting to get introduced to Houdini for VFX. It was designed in a way that even completely new Houdini users can easily pick up the main VEX concepts and start creating their own effects in a very short amount of time.
After viewing this course, people can expect to be able to confidently start writing VEX expressions and snippets of code to control the creation and modification of particle systems and volumes.
