title	Visual-Physical Grammars
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This paper introduces new visual-physical design grammars for the design and manufacture of building assembly systems that provide visually rich, culturally resonant design variations for housing. The building systems are intended to be tailored for particular cultures and communities by incorporating vernacular, decorative design into the assembly design. Two complementary areas of computational design research are brought together in this work: shape grammars and digital fabrication. The visual or graphic aspects of the research are explored through shape grammars. The physical design and manufacturing aspects are explored through advanced digital design and fabrication technologies and, in particular, build on recent work on mono-material assemblies with interlocking components that can be fabricated with CNC machines and assembled easily by hand on-site (Sass, 2007). This paper describes the initial, proof-of-concept stage of this work: the development of an automated, visual-physical grammar for an assembly system based on a vernacular language of Greek meander designs. A shape grammar for the two-dimensional Greek meander language (Knight, 1986) was translated into a three-dimensional assembly system. The components of the system are uniquely designed, concrete “meander bricks” (Figure 1). The components have integrated alignment features so that they can be easily fitted and locked together manually without binding materials. Components interlock horizontally to form courses, and courses interlock vertically in different ways to produce a visual variety of meander walls. The assembly components were prototyped at desktop scale with a layered manufacturing machine to test their appearance after assembly and their potential for design variations (Figure 2). Components were then evaluated as full-scale concrete objects for satisfaction of physical constraints related to concrete forming and component strength. The automated grammar (computer program) for this system generates assembly design variations with complete CAD/CAM data for fabrication of components formed from layered, CNC cut molds. Using the grammar, a full-scale mockup of a corner wall section was constructed to assess the structural, material, and aesthetic feasibility of the system, as well as ease of assembly. The results of this study demonstrate clearly the potentials for embedding visual properties in structural systems. They provide the foundations for further work on assembly systems for complete houses and other small-scale structures, and grammars to generate them. In the long-term, this research will lead to new solutions for economical, easily manufactured housing which is especially critical in developing countries and for post-disaster environments. These new housing solutions will not only provide shelter but will also support important cultural values through the integration of familiar visual design features. The use of inexpensive, portable digital design and fabrication technologies will allow local communities to be active, cooperative participants in the design and construction of their homes. Beyond the specific context of housing, visual-physical grammars have the potential to positively impact design and manufacture of designed artifacts at many scales, and in many domains, particularly for artifacts where visual aesthetics need to be considered jointly with physical or material requirements and design customization or variation is important.

title	Photogrammetry as an aid to lighting design for industrial interiors

summary	Photogrammetry methods have been shown to be useful as a tool for investigation of illuminance distribution and light losses in interiors containing obstruction configurations that approximate to simple rectilinear objects. This work examines the use of photogrammetry to model obstructions having a greater degree of complexity and a case study demonstrates the applicability of the technique to lighting design for a factory. The results confirm that this technology would accelerate the process of incorporating the effect of obstructions in routine lighting analysis and design.

title	Languages of Designs : from Known to New
source	Environment and Planning B. 1981. vol. 8: pp. 213-238 : ill. includes bibliography
summary	A procedure for defining new languages of designs from known or given ones is presented. It is specified in terms of shape equivalence rules or shape equivalence rule schemata which allow shapes in spatial relations given or inferred from existing design languages to be replaced with other shapes. The new spatial relations so defined can be used to determine a wide variety of new, original languages of designs. The possibility of using shape equivalence rules or rule schemata for characterizing formal compositional aspects of historic styles or languages of designs and relationships between them is also discussed

title	The Concept of a Meta-Font
source	Visible Language. Winter, 1982. vol. XVI: pp. 3-27 : ill. includes bibliography
summary	A single drawing of a single letter reveals only a small part of what was in the designer's mind when that letter was drawn. But when precise instructions are given about how to make such a drawing, the intelligence of that letter can be captured in a way that permits us to obtain an infinite variety of related letters from the same specification. Instead of merely describing a single letter, such instructions explain how that letter would change its shape if other parameters of the design were changed. Thus an entire font of letters and other symbols can be specified so that each character adapts itself to varying conditions in an appropriate way. Initial experiments with a precise language for pen motions suggest strongly that the font designer of the future should not simply design isolated alphabets; the challenge will be to explain exactly how each design should adapt itself gracefully to a wide range of changes in the specification. This paper gives examples of a meta-font and explains the changeable parameters in its design

title	Digital tea house: Japanese tea ceremony as a pretext for exploring parametric design and digital fabrication in architectural education
doi	https://doi.org/10.52842/conf.caadria.2011.071
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 71-80
summary	This paper reviews the Digital Tea House, a joint workshop in August of 2010 held at the University of Tokyo, Department of Architecture, together with Columbia University GSAPP. Three pavilions for hosting ceremony were designed and built in less than one month, in an attempt to bridge technology and culture not only through design but also fabrication. Issues addressed in the process included applications of computational design, interpretations of tradition and culture in spatial or activity oriented expressions, structural stability, to practical solutions for quick physical materialization. Three teams comprised of 6 to 8 students, each a blend of different nationalities, ultimately produced 3 full-scale tea houses with the same software, primary material, budget, and principal fabrication method.

summary	Scattered solid is a conceptual model consists of a pair of force sources - attractor and repulsor - and particles that possibly bonds together. We hypothesized an abstract or imaginary force field causing particles to move that we can control the tendency of organization by modifying the force fields with a set of parameters such as intensity by distance, time and geometry.

title	A PROCISSÃO" - Documentação Tridimensional de Arte Rupestre na Chapada Diamantina, Bahia ["THE PROCESSION" - Three-dimensional documentation of Rock Art in the Chapada Diamantina, Bahia]
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	Documentation of rock art is generally made by drawing with a marker over a plastic film overlaid to the wall of the canyon or cave where it is found. Taking out the drawing printed in the film from the wall implies in loosing important data about its contour because the image became rectified; information about the relief of the documented figure are lost as well. We have used close range photogrammetry methodology to overcome this problem and, on the other hand, to preserve information about the relief of the picture itself, taking into account the fragility of the rock support.

summary	Recently in Japan, streetscapes have been changing by repeated deregulations and redevelopments. In this paper, the desirable building forms and facades in Nihonbashi is examined through experiments using the VR system. Firstly the changes of impression in three streetscapes whose buildings forms and height are different are investigated. Secondly, the difference in impression of facades in the cases they are seen in streetscapes or seen individually is examined. Thirdly analysing the correlation of physical components and unique facades, the relation between attractiveness of streetscape and building forms and facades is clarified. From these results, way of design to create lively, emotional and unique streetscape in Nihonbashi is suggested.

title	Irregular Vertex Editing and Pattern Design on Mesh
doi	https://doi.org/10.52842/conf.acadia.2011.278
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 278-283
summary	This paper introduces an innovative computational design tool used to edit architectural geometry by addressing the problem of irregular vertices. An irregular vertex is a special kind of vertex which is connected with fewer or greater less or more edges than regular vertices on a mesh object. Irregular vertices create problems with further surface rationalization, as well as structural analysis and constructability of the surface. Geometry created using other tools can also be remeshed upon import. Using the developed tool, the user is able to identify irregular vertices, interactively change the type, and then move or remove these irregular vertices. Additionally, a computational tool to make various design patterns on the mesh after the topology has been edited is also developed. The workflow is illustrated step by step in the pipeline. The advantages and disadvantages of editing mesh topology on architectural geometry design including the limitations are discussed at the end.

summary	This paper outlines the work and organizational framework of World16, a working group of 16 professors from around the world that engage in collaborative research on virtual reality (VR) technologies. Because of the abundance of VR software and the resulting fragmentation of research efforts in this field, World16 shares knowledge and resources using a common software package. A common research platform facilitates the sharing of data and the coordination of research efforts among member professors spread around the world. In addition to the organizational practices of World16’s project management team, various tools and methods of sharing research are described. Additionally, World16’s major research projects are outlined as well as the successes and failures of working within a shared software platform. Lastly, future work and goals of World16 are discussed, including the marketing and commercialization of several computational tools created by member professors.
