Key Features
Develop creative mathematical thinking to work on procedural projects in Blender 4.5 LTS Learn how to calculate and create your very own math-based physics simulations Find out how you can utilize Geometry Nodes to scatter objects randomly in a scene
Book DescriptionGeometry Nodes are tools that enable you to manipulate and generate 3D geometry in a node-based workflow. In this updated edition, youll learn how to use the basic and intermediate features of Geometry Nodes that are essential for creating complex, physics-based simulations and animations in Blender 4.5 LTS. After an introduction to the Geometry Nodes system and its inner workings, youll learn about different node inputs and outputs, along with the basic nodes necessary for your Geometry Nodes projects. Youll apply your newfound knowledge through exercises that involve modifying curves, meshes, text, and more, as well as work on a range of interesting projects, including creating a procedural plant, a brick wall generator, and a procedural LED panel to explore different aspects of node-based modeling. The concluding chapters take you through a brand-new addition to Geometry Nodes called the Simulation Zone, where youll create various physics simulations such as a procedural fountain and bugs crawling over objects using the Geometry Node editor. By the end of this book, youll be able to tackle minor to major Geometry Nodes issues with confidence and create complicated Geometry Nodes trees and complex physics simulations tailored to your needs. *Email sign-up and proof of purchase requiredWhat you will learn
