程序化基础:理解3D和2D数据Understanding 3D & 2D Data with Houdini & Unreal Engine

If you are not clear about how computers interpret and manipulate data behind the scenes of pretty pixels we see on the screens then this tutorial can be of interest to you.

This is just one episode of the Proceduralism Basics series Dr. Hou is planning to release in the near future so stay tuned!

In this course, revisit some basics of proceduralism with Dr. Hou (a fictional Head of Training & Community Contributions @ First Iteration created & performed by Illia Statkevych) and learn how computers differentiate and store data in general, what kind of data is behind 3D objects and 2D pictures and how we can manipulate it using the code of a programming language like Houdini VEX or visual programming languages like Unreal Blueprints and Houdini Geometry Nodes or any other framework or platform.

This tutorial is great for artists who are new to procedural workflows or aspiring programmers who are just starting to learn about programming and proceduralism or anyone else who is interested to learn more about 3D & 2D data. This is not an in-depth course but an overview to get a better understanding so all that’s needed is an open mind & your attention.

After watching this class, the padawans should: have a better understanding of how data is stored in a computer; learn about various data types and why so many exist; understand the difference between variables, parameters & attributes; learn about classes, structures, arrays, matrices and other complex data types & lists in Unreal & Houdini; learn about how 3D objects are represented as data and what the difference between points, vertices, edges, primitives & detail in Houdini; have a better understanding of 2D data within Unreal shaders (materials) and how pixels & UVs are represented as data and how we can manipulate them procedurally to alter images real-time.

Key takeaways, learn about:

– how data is stored
– various data types (int, float, string, boolean and derivatives)
– variables, parameters & attributes
– classes, structures, arrays, lists, matrices, sets, maps & dictionaries
– 3D data (points, vertices, edges, primitives & detail)
– 2D data (pixels & UVs)
– shaders (materials)
– how the above looks like in Unreal Blueprints, Houdini Geometry Nodes and VEX

在本课程中,与 Hou 博士(由 Illia Statkevych 创建和执行的虚构的培训和社区贡献负责人@First Iteration)重温程序主义的一些基础知识,并了解计算机如何区分和存储数据,3D 背后的数据类型对象和 2D 图片,以及我们如何使用像 Houdini VEX 这样的编程语言或像 Unreal Blueprints 和 Houdini Geometry Nodes 这样的可视化编程语言或任何其他框架或平台的代码来操作它。

本教程非常适合刚接触程序工作流程的艺术家或刚开始学习编程和程序化的有抱负的程序员,或者任何有兴趣了解更多关于 3D 和 2D 数据的人。这不是一门深入的课程,而是一个概述,以便更好地理解,因此所需要的只是开放的心态和您的注意力。

看完这堂课,学徒们应该: 更好地理解数据是如何存储在计算机中的;了解各种数据类型以及为什么存在如此多的数据类型;了解变量、参数和属性之间的区别;了解 Unreal & Houdini 中的类、结构、数组、矩阵和其他复杂数据类型和列表;了解如何将 3D 对象表示为数据,以及 Houdini 中的点、顶点、边、图元和细节之间的区别;更好地理解虚幻着色器(材质)中的 2D 数据,以及如何将像素和 UV 表示为数据,以及我们如何通过程序操作它们以实时更改图像。

关键要点,了解:

– 数据是如何存储的
– 各种数据类型(int、float、string、boolean 和导数)
– 变量、参数和属性
– 类、结构、数组、列表、矩阵、集合、地图和字典
– 3D 数据(点、顶点、边、基元和细节)
– 2D 数据(像素和 UV)
– 着色器(材料)
– 以上在虚幻蓝图、Houdini 几何节点和 VEX 中的样子
