Surfaces with few facets The roof of Munich's Olympic Stadium, which covers and unifies the stadium, tracks, and pools, was developed using computerized mathematical procedures to determine their form and behavior, resulting in an architectural form of "minimal surfaces" first used in voltage covered with these dimensions: 74.800m2. They were designed by Henning Larsen and built by Coop Himmelb(l)au GmbH & Co. KG. Minimal surfaces have many applications in architecture because they can be constructed automatically by computers, without human intervention. For example, a car factory might use this technique to produce identical cars with only minor changes (such as adding different colors) by programming its computer to repeat certain shapes over and over again. Minimal surfaces also make buildings resistant to high winds because there are not very large openings between them and their foundations. The Olympic Stadium is one of the most innovative uses of this technology. It has been called "the world's first digital stadium." Such structures would not be possible without computers; otherwise, all buildings would look like cubes. The design process for the Olympic Stadium involved several steps. First, three-dimensional models were made with data collected during construction. These models were then analyzed mathematically to find out what shape would be optimal for resistance to wind and other forces. Finally, builders created physical prototypes to see if the predictions matched up with actual performance.
