summary

Geometric problems originating in architecture can lead to interesting research and results in geometry processing, computer aided geometric design, and discrete diﬀerential geometry. In this ar- ticle we survey this development and consider an important problem of this kind: Discrete surfaces (meshes) which admit a multi-layered geometric support structure. It turns out that such meshes can be el- egantly studied via the concept of parallel mesh. Discrete versions of the network of principal curvature lines turn out to be parallel to ap- proximately spherical meshes. Both circular meshes and the conical meshes considered only recently are instances of this meta-theorem. We dicuss properties and interrelations of circular and conical meshes, and also their connections to meshes in static equilibrium and dis- crete minimal surfaces. We conclude with a list of research problems in geometry which are related to architectural design.
