title 
Generalised cyclidic nets for shape modelling in architecture 
source 
International Journal of Architectural Computing vol. 14  no. 2, 148168 
summary 
The aim of this article is to introduce a bottomup methodology for the modelling of freeform shapes in architecture that meet fabrication constraints. To this day, two frameworks are commonly used for surface modelling in architecture: nonuniform rational basis spline modelling and meshbased approaches. The authors propose an alternative framework called generalised cyclidic nets that automatically yield optimal geometrical properties for the envelope and the structural layout, like the covering with planar quadrilaterals or hexagons. This framework uses a base circular mesh and Dupin cyclides, which are natural objects of the geometry of circles in space, also known as Mo?bius geometry. This article illustrates how complex curved shapes can be generated from generalised cyclidic nets. It addresses the extension of cyclidic nets to arbitrary topologies with the implementation of a ‘holefilling’ strategy and also demonstrates that this framework gives a simple method to generate corrugated shells.
