This paper tackles the challenge of designing and implementing a complete, operational, and extensible web-based virtual reality (VR) system for stored six degrees-of-freedom (6DoF) content. We present a unique, open-source volumetric video streaming system, termed WIDE-VR, that leverages cutting-edge web technologies, including a WebGL-based rendering engine, Draco's real-time inbrowser decoder, and HTTP/3 over QUIC transport. We also explore various adaptive streaming and viewport prediction strategies to achieve improvements in bandwidth efficiency, reduced rebuffering, and minimized quality fluctuations. Our experimental results demonstrate the system's capabilities and potential in delivering immersive, high-quality VR experiences directly via web platforms, fostering broader accessibility and scalability for VR applications.
