Procedural 3D Modeling Using Geometry Nodes in Blender

Develop a creative modeling style and node-based workflow by following step-by-step instructions in this book to learn the art of making practically any procedural mesh with ease while utilizing the power of geometry nodes

Key Features

• Discover an efficient way to use the geometry node editor
• Develop a creative mathematical thinking of the modeling workflow
• Work on some fun projects in the book to put your newly acquired skills to use

Book Description

If you are a CG artist already experienced with Blender but do not have extensive knowledge of Geometry Nodes, you will find great experience and ideas in this book. Learning this new feature in Blender is crucial to working in the CG Industry. You will learn how to use the basic and intermediate features of Geometry Nodes, a crucial part of your Blender roadmap.

We will start with getting to know the different node inputs and outputs. After that, we'll take a look at the basic nodes you'll be needing throughout your Geometry Nodes projects, along with explaining how the node system works. During each chapter, we will give you a practical implementation to try and apply your newfound skill; these exercises include modifying curves, mesh, and more. In the end, we will also teach you how to organize your nodes with the help of node groups.

By the end of this book, you'll be able to tackle minor to major geometry node issues with your newfound knowledge and apply this knowledge to make complicated geometry node trees exactly how you need them.

What you will learn

• Learn about the different node inputs and outputs that Geometry nodes have to offer
• Understand the flow of the geometry node system
• Discover the common nodes you'll be using along with their functions in the geometry node editor
• Learn about the different scatter methods along with how to utilize them
• Modify basic mesh primitives using the node system inside of Blender
• Scatter and modify objects aligned onto a curve
• Learn about the more advanced nodes in the geometry nodes system
• Utilize the learned nodes in your geometry nodes projects

Who This Book Is For

If you are a CG Artist or follow modeling careers like that of an environment artist or even a CG generalist in the cinematography industry and you are looking to get into learning a node-based modeling workflow using Geometry Nodes in Blender, this is the perfect book for you. You will need a basic knowledge of the fundamentals of Blender, for example, knowing the specific workflow of material nodes and being able to apply this knowledge to your projects. To get the most out of this book, you should have a basic understanding of Blender's shortcut system and some modeling experience.
