ASSEMBLE Introduction to Procedural Modeling with Geometry Nodes in Blender

几何节点是一种创建和修改 3d 对象的强大方法。由于这种建模方法对 Blender 来说是全新的，初学者和专家都必须从头开始学习这个新系统的基础知识。您无需成为 Blender 专业人士或数学高手即可学习几何节点！

在 Assemble 中，CG Cookie 讲师 Jonathan Lampel 将一步一步地指导您完成学习曲线，以便您可以开始创建自己的几何效果。该课程的重点是几何节点的#1 实际用例，它将模块化资产拼凑在一起以创建具有可调整和可动画属性的模型，但教授的概念是任何几何节点项目的基础。

本课程为中级水平，期望您熟悉 Blender 界面，了解 3d 建模的基础知识，并熟悉着色节点。

第 1 章
几何节点的基础知识
我们将从几何节点的基础知识开始，例如它如何适合修改器堆栈、节点插座的颜色和形状的含义、属性是什么以及如何使用它们以及如何知道您是应该手动建模还是使用节点建模。

第 2 章
生成摩天轮
您将了解最重要的节点，并创建一些可以在任何项目中重复使用的节点组。主要概念包括实例化模型、创建资产数组、生成新几何体、将各个部分拼接在一起以及优化节点图以获得更好的性能。

第 3 章
生成过山车轨道
您将制作一个沿着自定义曲线生成的过山车轨道，以及一个能够以任何速度可靠地沿着轨道移动的手推车。在此过程中，您将学习如何将对象与曲线对齐、使用条件属性、光线投射、使用节点求解方程以及程序动画。

CGCookie – ASSEMBLE Introduction to Procedural Modeling with Geometry Nodes in Blender

Info:
Geometry Nodes is a powerful way to create and modify 3d objects. Since this method of modeling is completely new to Blender, both beginners and experts alike will have to learn the fundamentals of this new system from scratch. You do not need to be a Blender pro or a math whiz to learn Geometry Nodes!

In Assemble, CG Cookie instructor Jonathan Lampel will guide you through the learning curve one step at a time so that you can begin to create your own geometry effects. The course is focused on the #1 practical use case for Geometry Nodes, which is piecing together modular assets to create models with adjustable and animatable properties, but the concepts that are taught are foundational to any Geometry Nodes project.

The course is intermediate level, and it’s expected that you are comfortable with the Blender interface, understand the basics of 3d modeling, and are familiar with shading nodes.

CHAPTER 1
The Basics of Geometry Nodes
We’ll start with the basics of Geometry Nodes such as how it fits into the modifier stack, what the colors and shapes of the node sockets mean, what attributes are & how to use them, and how to know if you should model something by hand or with nodes.

CHAPTER 2
Generating a Ferris Wheel
You’ll learn about the most essential nodes, and create a few node groups that you can reuse in any project. The main concepts include instancing models, creating arrays of assets, generating new geometry, snapping pieces together, and optimizing the node graph for better performance.

CHAPTER 3
Generating a roller coaster track
You’ll make a roller coaster track that’s generated along a custom curve and a cart that reliably moves along the track at any speed. Along the way you’ll learn about aligning objects to curves, using conditional properties, raycasting, solving equations with nodes, and procedural animation.
