XR Application Development with WebXR, Unity, and Unreal

Extended reality is transforming how we interact with the digital world, but getting started with XR development can feel overwhelming with so many tools available. This written course demystifies the technical landscape of AR, VR, and mixed reality, giving you a clear mental model to build immersive experiences. You will transition from an XR enthusiast to a developer who understands how to choose, configure, and develop projects across different environments. By exploring the core concepts of spatial computing, you will gain the confidence to structure XR applications for browsers, mobile devices, and headsets. What you'll learn: - Understand the foundational concepts of spatial computing, tracking, and the differences between AR, VR, and MR. - Explore the OpenXR standard and how it enables cross-platform compatibility across modern hardware. - Learn the basics of the WebXR Device API to build and deploy immersive experiences directly in the web browser. - Configure development environments in Unity and Unreal Engine specifically optimized for XR projects. - Apply core interaction patterns, user interface design principles, and locomotion mechanics for virtual environments. - Analyze performance considerations and optimization techniques to ensure smooth frame rates on mobile and standalone headsets. The course begins with essential terminology, hardware architectures, and spatial math concepts before guiding you through practical development workflows. You will read detailed explanations, analyze step-by-step configuration guides, and study code snippets for WebXR, Unity, and Unreal Engine. This course is designed for aspiring developers, web designers, and tech enthusiasts who are new to XR development and want a structured, text-based introduction with no prior game engine experience required.
