summary	Configurational studies are useful tools to architectural designing, since they help to understand the grouping of objects in the space (two-dimensional and/or threedimensional). The designer, after a classification of objects that satisfies the needs set to a group of objects, impose some restrictions to the objects that will govern the composition. These restrictions are those that will define the result through operations carried out by the designer. Among these operations the location of buildings in a determined area and the particular environmental qualities condition the final result. This work presents the results obtained by means of the implementation of a computing program of the type Evolution Program (EP) implemented in language C. The implementation of the program is explained in the first part of the paper. In the second part the successive steps are described. The numerical results obtained with the mentioned program are shown graphically. Examples of different complexity level illustrate the discussion of the theoretical matters.

title	Spirospaces in Architectural Design
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	The proposal of this paper is to present "Spirospaces" and their utility in Architectural Design, exploring their relation with other geometrical disciplines such as knot theory, tiling and patterns generation. A spirospace is a geometrical entity generated from the spatial interpretation of a "Spirolateral", a well known bidimentional entity. A computer program to generate spirospaces configurations is presented and demonstrated with several examples. This is complemented with the exposition of the mathematical framework that supports closed spirospaces generation.

summary	This paper presents a parametric shape grammar that explains the generation of the structural forms of the Spanish designer Santiago Calatrava. The shape grammar is divided into two separate grammars a lower level grammar and a higher level grammar. The lower level or first grammar is composed of rules to generate a “fundamental unit” design, which has the characteristic to be a single component with non-repetitive parts that becomes the primitive object of the design. The higher level or second grammar is composed of rules that generate the overall design by recursive application of Euclidean transformations to the fundamental unit. We concentrate our discussion on the higher level or second grammar to demonstrate the process of generating complex designs by application of simple rules.

summary	We present studies and advances that link two I+D+T projects based in FADU and FI UNMdP, Argentina. These studies, started this year, have the common aim from two complementary visions, enriching an indexed and classified heritage about Open Educational Resources and repositories in postdigital environments and academic areas. This is a collaborative and interdisciplinary work with the purpose of supporting the improvement of presence, semi-presence, and distance educational process, and helping free and equal access to different available educational resources. At this state, in particular, we are interested in contributing to the improvement of REA interface designs and repositories through providing heuristic lists that join later an analysis and evaluation interface model.

source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 186-189
summary	A Hypermedia system is, morphologically speaking, an information structure which organizes a set of elements of alphanumeric and graphic nature as a web. This enables a multidimensional access from specific interests. One of the most widespread hypermedia applications is within the field of education. There should be validation criteria which contribute to systematize and direct design processes for didactic hypermedia. This work aims at becoming a contribution by analyzing the relations and effects produced by the number of links and node sizes on some basic didactic uses; particularly, within information search, learning and attitude towards hypermedia. From the results obtained, we propose guidelines for the design of didactic Web Sites and CD Rom.

summary	Hipermedia lead to a non- linear organization of information, where the user decides the path to follow and the relations among the different information blocks. They constitute starting points for establishing both social and sin gu lar “sense genealogies”. Sense production by means of mutimedia access and the resignifying of information correspond, within the Theory of Science Didactics, to the concept of thematic decentering. This concept refers to fl exibility and transference modes, opposed toseg men ta tion and which enable to explore, approach and relate different topics and complexities. It is supposed to generate more cultivated individuals by broadly linking science, technology and art. Within this theoretic frame work, the work presents the de vel op ment of a hipermedium on the Villa Victoria Cultural Center, which aims at a didactic treat ment of cultural spaces as object of knowl edge.

title	Thonet Chairs Design Grammar: a Step Towards the Mass Customization of Furniture
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 181-200.
summary	The paper presents the first phase of research currently under development that is focused on encoding Thonet design style into a generative design system using a shape grammar. The ultimate goal of the work is the design and production of customizable chairs using computer assisted tools, establishing a feasible practical model of the paradigm of mass customization (Davis, 1987). The current research step encompasses the following three steps: (1) codification of the rules describing Thonet design style into a shape grammar; (2) implementing the grammar into a computer tool as parametric design; and (3) rapid prototyping of customized chair designs within the style. Future phases will address the transformation of the Thonet’s grammar to create a new style and the production of real chair designs in this style using computer aided manufacturing. Beginning in the 1830’s, Austrian furniture designer Michael Thonet began experimenting with forming steam beech, in order to produce lighter furniture using fewer components, when compared with the standards of the time. Using the same construction principles and standardized elements, Thonet produced different chairs designs with a strong formal resemblance, creating his own design language. The kit assembly principle, the reduced number of elements, industrial efficiency, and the modular approach to furniture design as a system of interchangeable elements that may be used to assemble different objects enable him to become a pioneer of mass production (Noblet, 1993). The most paradigmatic example of the described vision of furniture design is the chair No. 14 produced in 1858, composed of six structural elements. Due to its simplicity, lightness, ability to be stored in flat and cubic packaging for individual of collective transportation, respectively, No. 14 became one of the most sold chairs worldwide, and it is still in production nowadays. Iconic examples of mass production are formally studied to provide insights to mass customization studies. The study of the shape grammar for the generation of Thonet chairs aimed to ensure rules that would make possible the reproduction of the selected corpus, as well as allow for the generation of new chairs within the developed grammar. Due to the wide variety of Thonet chairs, six chairs were randomly chosen to infer the grammar and then this was fine tuned by checking whether it could account for the generation of other designs not in the original corpus. Shape grammars (Stiny and Gips, 1972) have been used with sucesss both in the analysis as in the synthesis of designs at different scales, from product design to building and urban design. In particular, the use of shape grammars has been efficient in the characterization of objects’ styles and in the generation of new designs within the analyzed style, and it makes design rules amenable to computers implementation (Duarte, 2005). The literature includes one other example of a grammar for chair design by Knight (1980). In the second step of the current research phase, the outlined shape grammar was implemented into a computer program, to assist the designer in conceiving and producing customized chairs using a digital design process. This implementation was developed in Catia by converting the grammar into an equivalent parametric design model. In the third phase, physical models of existing and new chair designs were produced using rapid prototyping. The paper describes the grammar, its computer implementation as a parametric model, and the rapid prototyping of physical models. The generative potential of the proposed digital process is discussed in the context of enabling the mass customization of furniture. The role of the furniture designer in the new paradigm and ideas for further work also are discussed.

summary	The realization of architecture, that is the building of the physical artifact, requires numerous collaborative participates that requires a communication network in order to realize the vision. All efforts to communicate a design idea prior to physical realization, that is manufacturing or construction, are forms of visualization (i.e. representation). Herein lies the fundamental problem, the designer(s) must en-vision, and communicate that which is to BE ... physical, yet is NOT... physical. In this paper, we will review the emerging Human-Computer-Interface and technology influences on process and product; here we find the “humanistic” component is a critical factor in the success of “digital” strategies.

summary	Current design studio pedagogy is undergoing significant change as the means and methods of ideation, representation and making evolve with digital tools; Computer-Aided-Design-Computer-Aided-Manufacturing (CADCAM) remains a contentious topic among many studio instructors and faculty in the academy. Computing is now nearing ubiquity; many processes and products have seen significant evolutionary trends, if not revolutionary transformations; this is no less the case in the academic and firm design studio. The impact of “digital” media and CADCAM, in the design-make process, remains obscure and formally unknown.In this paper, we will review our research and findings from the work of three students; two current students who were in our Digital Design II (DDII) spring 2006 course and the third student, the writer, will reflect on “design and making” from a “pre-architecture” and pre-studio/pre-computer (CADCAM) perspective of ‘making’ thirty-three years ago. The research findings provide universal precepts pertinent to current thinking about emerging studio pedagogy. Our findings suggest that computing technology should be introduced at the outset of design education for the beginning student in basic design studio; and moreover, advanced designers can partner with “digital” tools to ideate and realize their, heretofore unrepresentable and unconstructable, ideas in the early stages of design using CADCAM.

summary	Currently most professional modeling and computer graphics software packages embed a scripting language. This is an early report on collecting data about software applications and coding tools geared towards the educational environment, preparing a listing for further evaluation and analysis of platforms. An increase in the adoption of Python as the embedded scripting syntax in many established tools can already be recognized, therefore the creation of educational materials on Python for design and architectural education merits further attention. Other insights on the educational potential of the available tools might be gained by advancing the data collection and evaluation work.

title	The Beta2-spline : A Special Case of the Beta-spline Curve and Surface Representation
source	IEEE Computer Graphics and Applications September, 1985. vol. 5: pp. 46-58 : ill. includes bibliography.
summary	This article develops a special case of the Beta-spline curve and surface technique called the Beta2-spline. While a general Beta-spline has two parameters (B1 and B2) controlling its shape, the special case presented here has only the single parameter B2. Experience has shown this to be a simple but very useful special case that is computationally more efficient than the general case. Optimized algorithms for the evaluation of the Beta2-spline basis functions and rendering of Beta2-spline curves and surfaces via subdivision are presented. This technique is proving to be quite useful in the modeling of complex shapes. The representation is sufficiently general and flexible so as to be capable of modeling irregular curved-surface objects such as automobile bodies, aircraft fuselages, ship hulls, turbine blades, and bottles
