Kurzfassung deutsch:
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 realizing double curved surfaces as e.g. steel/glass constructions with planar faces remain hardly explored. Planar quadrilateral faces and true freeform geometries seemed mutually exclusive. Only recently the high potential of optimized mesh geometries has been realized. The aim of our present research is the computation and interactive design of planar quadrilateral meshes (referenced as PQ meshes) with specific properties relevant for design, construction and production processes in the field of architecture. PQ Meshes are not only capable of realizing the entire spectrum of freeform shapes, but at the same time provide the basis for multi-layer support and cladding structure with planar faces and optimized joints with no geometric torsion. Our work on meshes with planar faces and face/face and edge/edge offset properties, on mesh parallelism, on subdivision methods for interactive design and on the problem of segmenting a surface into a geometrically optimized mesh has already been addressed in (Pottmann et al, 2006) and (Brell-Cokcan and Pottmann H., 2006)
In this paper we will focus on the architectural challenges of PQ Meshes. First we will discuss the problem of PQ Mesh Design for arbitrary freeform facades throughout an architectural design and planning process. Second we will investigate the problem of approximating referenced arbitrary freeform facades with PQ Meshes.
