Nowadays, many commercial CAD systems support history-based, constraint-based and feature-based modelling. The use of these new capabilities raises the issue of persistent naming which refers to the problem of identifying entities in an initial parametric model and matching them in the re-evaluated model. The goal of this paper in to propose a naming mechanism and an hierarchical structure enab...
In this paper, we present newly explored families of rigid-foldable cylinders and the cellular structures constructed from these cylinders; the families include zonogon extrusion cells, bi-directionally flat-foldable cells, and a novel type of cells, i.e., woven cylinder cells. We show the geometry of such structures to demonstrate their validity, their parametric design method, and their kinet...
In this paper we address performance oriented design applied to adaptive architecture in order to satisfy the performance requirements for changing contextual conditions. The domain of adaptive architecture is defined and specific focus is given to form-active architecture, in which geometric changes occur as a means of adaptivity during the use of the building. A parametric design approach and...
Several experiments combining analog design with digital parametric design have been presented, where the relationship between material properties and the designed shape of an architectural element play an important role. This approach allows to create digital material formations or to structure freeform surfaces, control their tectonics, through parametric modulation. Similar research tasks we...
This paper documents the development of Caress, an electroacoustic percussive instrument that blends drumming and audio synthesis in a small and portable form factor. Caress is an octophonic miniature drum-set for the fingertips that employs eight acoustically isolated piezo-microphones, coupled with eight independent signal chains that excite a unique resonance model with audio from the piezos...
This paper deals with a new method to design polyphase spreading sequences for DS CDMA wireless applications. The method is based on weighting symbols of the orthogonal Walsh sequences by the complex factors being symbols of baseband chirp sequences. The resulting sequences possess good aperiodic correlation properties, while maintaining the orthogonality. Because of the parametric design, the ...
This paper presents results from a Computational Fluid Dynamics (CFD) based parametric design study of two-dimensional downwind sail sections. By varying draft and camber a range of sail shapes are generated that cover the typical range of an America’s Cup Class (ACC) downwind sail inventory. In order to reduce simulation times only a solitary downwind sail is used, i.e., the influence of the m...
The author and associated researchers have in previous projects adapted videogame technology for design in the context of architectural design education. This paper reflects on this body of research: the original motivations and aspirations; what threads may be productively revisited; how contemporary shifts to parametric design and building information modelling may be incorporated; and consid...
Quality designs generally emerge from a conceptual design process that generates and communicates large design spaces of objectives, alternatives, impacts, and values. Parametric modeling is a popular means for generating large alternative spaces but it is difficult to use effectively when the other spaces are not well generated. We apply a framework for measuring design space clarity and quali...
The paper presents experiments in learning in a multi-agent design system. Inductive techniques are used to construct models of other agents’ behaviors, by relating design requirements to design proposals. The models are used to anticipate future design proposals and reduce the amount of interaction needed to find solutions for parametric design problems.
