Beginning with the evolution and capabilities of 3D web development, this book covers the foundational tools, setting up your environment for Three. js, Next. js, AWS Amplify, Storybook, and Tailwind CSS. It then explores Three. js fundamentals, covering geometries, materials, lighting, cameras, textures, user interactions, and animations to create dynamic 3D scenes. The book then seamlessly integrates Three. js with Next. js, teaching data management, state handling, and advanced interaction patterns. Crucially, you will learn vital optimization techniques and leverage AWS Amplify for secure hosting, user authentication, data storage, and real-time functionalities. The final sections guide you in establishing a consistent UI design system with Storybook, culminating in a complete, practical application.
