Foundations of VR and AR Development: Building XR Experiences

Immersive technologies like Virtual Reality (VR) and Augmented Reality (AR) are transforming how we interact with digital information and the physical world. This text-based guide equips you with the foundational principles and practical technical concepts required to start building immersive XR applications. You will begin with essential spatial computing definitions, tracking mechanics, and 3D coordinate frameworks before exploring interaction design, rendering optimization, and modern platform standards. What you'll learn: - Understand core XR terminology, spatial computing foundations, and tracking systems (3DOF vs. 6DOF) - Learn 3D scene architecture, coordinate systems, and physics principles for immersive environments - Explore modern spatial interaction paradigms, including raycasting, direct manipulation, and hand-tracking inputs - Master performance optimization techniques for mobile AR and standalone headsets, including draw call management and LOD strategies - Understand modern open standards such as OpenXR and universal interaction toolkits - Design intuitive spatial user interfaces and ergonomic user flows that minimize motion discomfort The material begins with foundational definitions and hardware architectures before guiding you step-by-step through interaction mechanics, scene setup, and deployment considerations. This course is designed for beginners, developers, and designers with no prior XR experience required.
