How the visualisations were made
Every graphic on this site is a conceptual 3D scene made of dots, drawn live in the browser (three.js). The Palace of Culture and Science is simplified from photographs, and drones and screens are enlarged for legibility. In the scenes, drones always fly outside building outlines. The visualisations show what a show could look like – they do not depict flights that have taken place.
