Building 3D, VR, and AR Experiences with WebXR and JavaScript

The modern web is shifting from flat two-dimensional pages to immersive, spatial experiences. Understanding how to integrate 3D graphics, virtual reality, and augmented reality directly into the browser is becoming an essential skill for forward-thinking web developers. This text-based course guides you through the foundational concepts of 3D web development, showing you how to render interactive objects and build immersive WebXR experiences. You will learn how to leverage powerful JavaScript libraries and native browser APIs to create responsive, spatial environments that run smoothly across both desktop browsers and mobile headsets. What you'll learn: - Understand core 3D graphics concepts including meshes, materials, lighting, and cameras. - Build interactive 3D scenes using popular JavaScript libraries like Three.js and A-Frame. - Implement the WebXR Device API to support virtual reality (VR) and augmented reality (AR) devices. - Configure user interactions, spatial tracking, and controllers for immersive environments. - Optimize 3D rendering performance for mobile devices and standalone VR headsets. - Apply modern responsive design principles to ensure spatial experiences degrade gracefully on standard screens. The course begins with foundational definitions of 3D math, coordinate systems, and rendering pipelines before moving into practical code examples. You will progress from simple static shapes to complex, interactive VR and AR web applications through structured written explanations and step-by-step code walkthroughs. This course is designed for web developers with a basic understanding of HTML and JavaScript who want to step into the spatial web. No prior experience with 3D graphics or game engines is required.
