About This Book
Max 6 and TouchDesigner are both high-level visual programming languages based on the metaphor of connecting computational objects with patch cords. This guide will teach you how to design and build high-quality audio-visual systems in Max 6 and TouchDesigner, giving you competence in both designing and using these real-time systems. In the first few chapters, you will learn the basics of designing tools to generate audio-visual experiences through easy-to-follow instructions aimed at beginners and intermediate. Then, we combine tools such as Gen, Jitter, and TouchDesigner to work along with Max 6 to create 2D and 3D visualizations, this book provides you with tutorials based on creating generative art synchronized to audio. By the end of the book, you will be able to design and structure highly interactive, real-time systems.
Frequently asked questions
