Houdini School – HS-118 – Attributes

理解属性是成功在 Houdini 中构建项目的基础。在此录制课程中，您将专注于构建核心知识、揭开属性的神秘面纱、讨论如何创建属性，最重要的是解释如何将它们集成到 Houdini 中。课程主题包括基本几何组件、术语说明、不同的创建和管理方法，以及探索 VEX、HScript 和 Python 之间的差异。上完本课程后，您将更清楚地了解如何构建属性、解决常见问题以及提取项目所需的数据。

第 1 节

基金会

本课程将重点关注理解几何组件的核心基础、属性的实际含义、属性的类别和类型，以及数据顺序的优先级。

第 3 节

本机属性

本次会议将重点介绍如何使用 Houdini 提供的原生属性，在某些情况下，这些属性需要执行各种模拟任务。会议将展示大量示例构建，包括 RBD、FLIP、Vellum、Crowds 和 Viewport GL 功能。

Houdini School – HS-118 – Attributes

Info:
Understanding Attributes is fundamental to successfully building projects in Houdini. In this recorded class, you will focus on building your core knowledge, demystifying Attributes, discussing how to create them, and most importantly explaining how they are integrated into Houdini. Class topics include basic Geometry components, clarification of the terminology, different creation & management methods, as well as exploration of differences between VEX, HScript, and Python. After this class, you will have a clearer understanding of how to build attributes, troubleshoot common issues, and extract the data you need for your projects.

Session 1

Foundations

This session will focus on the core foundations of understanding geometry components, what attributes actually are, their classes & types, as well as the precedence the data order takes.

Intrinsics

Session 2

Reading, Writing, and Organization

This session will focus on what attributes are NOT, VEX, VOPs, HScript, Python, Local & Global variables, $ versus @, creation methods, writing methods available to customize your own attribute data, as well as parameter usage.

Session 3

Native Attributes

This session will focus on reviewing and using native attributes Houdini provides, and in some cases requires to perform various simulation tasks. Lots of example builds will be shown, including RBD, FLIP, Vellum, Crowds, and Viewport GL features.
