Abstract
Discrete differential geometry aims to develop discrete equivalents of notions and methods from smooth surface theory. It constitutes an area of active research in mathematics, but also provides effective methodology for a variety of applications. This talk will illustrate the fruitful interplay between theory and applications of discrete differential geometry at hand of selected topics in architectural geometry and computational fabrication. We discuss the construction of architectural freeform skins from flat, nearly rectangular panels, and associated support structures. These discrete surfaces are in a certain sense the smoothest polyhedral approximations of a given smooth surface. Other representatives of such discrete structures are related to curved folding patterns and origami. We also address the design and fabrication of gridshells from simple elements and various problems related to design and fabrication with isometrically deformable materials.
