Prototype development of a cross-reality digital twin ecosystem: the web, open source and open data

This work contributes to a broader initiative aimed at transforming a former industrial port area into a dynamic Knowledge Transfer Space (KTS). To support this transformation, we explore the development of a cross-reality (CR) digital twin of the port area, which integrates user interfaces with varying degrees of virtuality. We evaluate different web technologies, focusing on the balance between accessibility, immersion, scalability, and performance. By comparing client-side rendering with pixel streaming approaches, we aim to identify suitable solutions for prototyping a CR digital twin ecosystem. The development of a prototype is ongoing, based on a client-side rendering approach. The outcomes contribute to developing an open and transferable CR digital twin applicable to similar urban projects in other cities.
