Description

Introduction

This course covers the development of augmented reality (AR) and virtual reality (VR) experiences that run directly in web browsers. Participants will explore web-based AR/VR frameworks such as WebXR, A-Frame, and Three.js, enabling them to create immersive experiences without the need for dedicated applications or platforms. The course focuses on the unique challenges and opportunities of building AR/VR experiences for the web, including cross-platform compatibility and performance optimization.

Prerequisites

1. Basic understanding of web development (HTML, CSS, JavaScript).
2. Familiarity with 3D concepts and basic programming.
3. Prior experience with AR/VR tools (optional but beneficial).
