Mitte Basel is an interactive data visualisation exploring the urban development of Basel city over time. The project maps the densification and spatial growth of the district through a real-time 3D environment, allowing viewers to navigate temporal layers of urbanisation across different periods. Built primarily in TouchDesigner, the piece combines geospatial data with generative 3D rendering to produce an immersive, interactive experience that makes the city's architectural history legible at a glance.
