For the video projection on a large portion of the over 5,000 sq. m ceiling membrane and using 14 Barco video projectors, a special interactive playback system was developed, set up and supervised for the duration of the trade exhibition, on behalf of and in cooperation with Atelier Markgraph (Art direction membrane projection: Eno Henze).
The entire amorphous projection surface combined with extremely varied projector positions, were a particular challenge for the adjustment of the image distortion and the soft edges. To this end, a 3D real time system was developed that was based on the 3D planning data and a simulation of the actual projector positions. The system allowed playback of prepared video content and additionally allowed the integration of generative elements into the show loop.
Furthermore, special controller modules for the laser projection on the frieze were developed and these were integrated into the system and into the production as a whole.
