In particular, we can quickly sketch and formulate RF designs with extended number of RF-units, and easily manipulate and preview a wide variety of RF patterns with feasible geometric parameters. Our design tool can free us from various engineering considerations, and allow us to focus on the aesthetic aspect of designs. 2013) for designing RF-structures has the following three key contributions: (1) it develops coherent 2D RF-tessellations by connecting RF-structures and plane tiling (2) it lifts the 2D RF-tessellation to 3D over a guiding surface and forms an approximated RF-structure by conformal mapping for interactive preview and (3) since conformal mapping cannot ensure collinear contact joints along each rod, we devise further a novel optimization model to ensure collinear contacts while preserving the geometric properties of RF-structures. 2011), existing research still focuses more on engineering issues such as stability, and not on the design. Though computational methods for RF-structures have been employed recently by the architectural community (Pugnale et al. Currently, approaches taken by architects are either manual and tedious (Gelez and Saby 2011), or too restrictive with limited user controls (Brocato and Mondardini 2010 Thönnissen and Werenfels 2011). Even though the structures are made up of just simple rods, no central supports are required to physically maintain the structure.ĭesigning RF-structures with a small number of RF-units is not easy but manageable, while designing RF-structures that span over large domains is intricate and complex. In general, rods are put together to form a closed circuit called RF-units, while multiple RF-units can be further put together to form large RF-structures. A reciprocal frame (RF) (Popovic Larsen 2008) is a self-supported 3D structure made up of three or more sloping rods.
