Procedural Content Generation for Games: Automate 3D Asset and Environment Creation with Blender Python and Geometry Nodes

You will start by getting comfortable with generating geometry in Blender Python by automating hand modeling basics, like blocking out weapon meshes by combining primitives and manipulating them with your favorite operators and modifiers. After that you’ll take a deep dive in geometry nodes and tackle projects such as adding Voronoi cracks and creating sliceform versions of any mesh. Building on your Blender Python skills, you’ll progress to fractal methods for generating realistic terrain, followed by grammar-based approaches such as L-systems for producing lifelike plants. Prefer environments based on real-world locations? Find out how to generate 3D contents based on GIS data, such as city skylines from building footprints, and 3D terrain from Digital Elevation Models (DEM). Along the way, you will also learn techniques for incorporating parametric modeling into your procedural system to optionally control chosen aspects of the generation process, to ensure that only meaningful variations coherent with the overall design are produced.

Whether you are looking to generate stylized content that aligns with your artistic vision, or realistic environments true to their real-world counterparts, this book will add a variety of practical (and fun) techniques to your procedural generation arsenal.

Who Is This Book For

This book is for software developers who want to procedurally generate 3D assets and environments for their game or simulation project. Readers with high-level understanding of the 3D content pipeline and either already using Blender or are interested in learning the basics on their own would benefit from the book. In addition, the ideal readers will already know some Python basics or are motivated to pick them up along the way from resources outside the book.
