Digital utopias and real cities-computer-generated images in re-design of public space

Abstract

Virtual environments are seen nowadays as extensions of our physical activities in the city. Are people, however, aware what the digitally mediated cities they live in are? The starting point of my paper is a question of how computer-generated images (CGIs) influence human perception of real space. I am interested in the conflict between a vision and reality, which occurs when an architectural project materialises in a public space and is subsequently rejected by the inhabitants. To explain this conflict, I will use the notion of digital utopias and compare CGIs with the great tradition of â€â€paper architecture. I will analyse two case studies from a medium-sized Polish city∗Poznan . The first case is a redevelopment of the Main Railway Station; the second is a re-design of a local square in Poznan . The analysis focuses on the ambiguity of CGIs used to advertise new investments. The Station in the phase of digital visualisation was appreciated by the Poznan inhabitants but when the project was finally realised, strong criticism of its users followed. The second one provoked public protests already in the phase of visualisation. In conclusion, I state that the concept of agonistic public spaces should be expanded and its virtual dimension should be taken into consideration as well. When dealing with hyper-realistic CGIs, we experience a certain utopia. Confronted with their material execution, we often experience dystopian disillusion which stirs us into action.
