Research project: Freeform Surfaces in Architecture

One part of this research is project `Computing Multilayer Freeform Surfaces', funded by the Österreichische Forschungsförderungsgesellschaft (FFG), which is conducted in cooperation with TU Wien and Waagner-Biro. Another part is the the project `Computational Differential Geometry', which is part of the National Research Network Industrial Geometry" (S92), funded by the Austrian Science Fund (FWF).


The implementation of freeform shapes in architecture is an area which encompasses great challenges in engineering as well as novel design ideas, and which consequently has high public exposure. However, the geometric basics of doubly curved surfaces realized as steel/glass constructions with planar faces remained largely unexplored. Planar quadrilateral faces and truly freeform geometries seemed mutually exclusive. Only recently the high potential of optimized mesh geometries has been realized: the aim of the present research project is the computation and interactive design of meshes with specific properties relevant for the construction process. They are not only capable of realizing the entire spectrum of freeform shapes, but at the same time provide the basis for a multi-layer support structure with planar faces and optimized joints without geometric torsion (Date: 10/2008)
