Introduction to 3D Web Development and WebXR

The web is evolving from flat two-dimensional pages into immersive, spatial experiences. Understanding how to build 3D, virtual reality (VR), and augmented reality (AR) applications directly in the browser is becoming an essential skill for modern developers. In this text-based course, you will transition from a traditional web developer into a spatial web creator. You will learn how to render three-dimensional objects, handle user interactions in virtual environments, and leverage browser APIs to deliver immersive experiences across mobile devices and headsets without requiring external applications. What you will learn: Understand the foundational concepts of 3D space, coordinates, and WebXR terminology; Explore real-world use cases of web-based AR and VR in industries like architecture, medicine, and retail; Configure basic 3D scenes with cameras, lighting, materials, and meshes; Implement the WebXR Device API to detect and target VR and AR hardware; Practice writing clean, modern JavaScript to handle spatial user inputs and controllers; Optimize 3D web performance and implement responsive design principles for mobile devices. You will start with core 3D math and graphics terminology before moving into practical code walkthroughs. The material guides you step-by-step through setting up a scene, adding interactivity, and deploying immersive web experiences. This course is designed for web developers and designers who are new to 3D graphics and WebXR, requiring only basic knowledge of HTML and JavaScript.
