Building Web AR Applications with Three.js and WebXR

Augmented reality is no longer confined to native mobile apps; modern web browsers can now host fully interactive AR experiences. This course guides you through bringing 3D virtual objects into the real world using the powerful combination of Three.js and WebXR. You will transition from understanding basic 3D rendering to deploying responsive, web-based AR applications. Through written explanations and practical code walkthroughs, you will learn how to handle camera feeds, detect real-world surfaces, and position interactive 3D assets seamlessly. What you'll learn: - Understand the foundational concepts of WebXR and the AR session lifecycle - Configure Three.js scenes specifically optimized for augmented reality rendering - Implement hit-testing to detect real-world surfaces and place 3D objects - Manage lighting estimation to make virtual models blend realistically with the physical environment - Resolve cross-browser compatibility challenges for both Android and iOS devices - Optimize performance and asset loading for smooth mobile web experiences The course begins with core terminology and setting up your first AR-enabled local development environment, then progresses step-by-step through user interaction, lighting, and deployment best practices. This text-only course is designed for web developers who are new to augmented reality; while basic familiarity with JavaScript is helpful, no prior experience with 3D graphics or WebXR is required. Start reading today and build your first browser-based augmented reality experience.
