The project Virtual [email protected] aims to compile expertise in modelling, simulation, urban planning, computer science and other research fields to build a dynamic and interactive virtual city platform. Central to the project is the development of a 3D-platform that allows the integration of different models and data into a single platform. In the first project phase (2018), virtual twins of the two Chalmers campus sites (Lindholmen and Johanneberg) will be modeled directly as an immersive 3D world (open-ended city). The 3D-platform will serve as a multipurpose arena for researchers featuring First Person and Real Time Strategy user perspectives as well as real-time coupling of simulations and data. In addition, Mixed Reality (MR) and Virtual Reality (VR) capabilities will enhance the user experience.
