title	Hybrid Art > Synthesized Architecture
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This paper investigates possible intersections between some contemporary artistic modalities and architectural practice. At first, it describes and discusses different uses of art in architectural history. Through the analyzes of Le Corbusier’s artistic and architectural practices, it observes the limits of looking at art as only ‘inspiration’ for architectural form and points to the necessity of surpassing this formal approach. More than bringing pictorial ‘inspiration’, art, as a experimental field, can change our architectural procedures and approaches - a much richer and powerful addition to the development of architecture. It discusses then, the confluence of architecture, information and communication technologies. Very commonly present in our contemporary life, not only on the making of architecture – computer drawings and modeling of extravagant buildings – nor in ‘automated rooms’ of the millionaire’s houses. Televisions, telephones and computers leave the walls of our houses “with as many holes as a Swiss cheese”, as Flusser has pointed. The architecture has historically manipulated the way people interact, but this interaction now has been greatly changed by new technologies. Since is inevitable to think the contemporary world without them, it is extreme urgent that architects start dealing with this whole universe in a creative way. Important changes in architecture occur after professionals start to research and experiment with different artistic medias, not limiting their visions to painting and sculpture. The main hypothesis of this paper is that the experiments with new media art can bring the field of architecture closer to information and communication technologies. This confluence can only take form when architects rise questions about technology based interaction and automation during their creative process, embodying these concepts into the architecture repertoire. An educational experience was conducted in 2007 at UFMG Architecture School, in Brazil, with the intention of this activity was to allow students to research creatively with both information technology and architecture. The students’ goal was to create site-specific interventions on the school building, using physical and digital devices. Finally, the paper contextualizes this experience with the discussion above exposed. Concluding with an exposition of the potentialities of some contemporary art modalities (specially the hybrid ones) in qualifying architectural practices.

title	A Computational Analysis of Fractal Dimensions in the Architecture of Eileen Gray
source	Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 256-263
doi	https://doi.org/10.52842/conf.acadia.2008.256
summary	This paper is the first investigation of the fractal dimensions of five of the house designs of Eileen Gray; a prominent architect working mainly in France between 1922 and 1956. In this paper, a computational variation of the “box-counting approach” (used to determine fractal dimension) is applied to a multi-dimensional review of the houses of Gray. As a contemporary of Le Corbusier, Gray is a significant architect for such an analysis. This research is important because it expands the set of examples of early Twentieth Century architects who have been analyzed using the method. This paper provides a computer-assisted mathematical analysis of characteristic visual complexity in five houses designs by Eileen Gray.

title	The Computer Methods of Construction Spiral Structures
source	Proceedings of the 8th European Architectural Endoscopy Association Conference
summary	The object of our research is geometric characteristics of spiral structures which are widely spread in nature (cones, sunflower beds…). It is a well-known fact that there is a proportional intercommunication according to the “golden section”. The correlation of the quantity of “right” and “left” spirals ties to have an irrational coefficient of “golden section” through the correlation numbers of 1,618… from Fibbonacci series ( 5/3, 8/5, 13/8, 21/13, 34/21, 55/34 …). When the proportion of “golden section” was found in the natural objects since the middle of the 19-th century (A.Zeizing), there began to appear a lot of hypotheses about some special aesthetic and technological characteristics of this proportion. The proportion of “golden section” became the most important architectural instrument in the first half of the 20-th century. This instrument made it possible to design beautiful and comfortable buildings (Le Corbusier). We tried to find a geometric way of building spiral structures which would be similar to natural ones. We solved this problem with the help of the developed algorythm the geometric characteristics of the cells of which spiral structures are built were investigated. It was found out that the cells of “golden” spiral structures don't have any special characteristics if compare with the cells of other spiral structures. During our work we found some spiral structures which have optimal geometric characteristics. These structures let's call them radial-hexagonal, have maximal area of a cell, though they have minimum perimeter. We also defined the main difference in the growing strategy of animate and inanimate structures. Inanimate structures grow by means of addition external elements. Animate structures grow by means of constant pushing of new elements which appear in the centre towards periphery. The optimal filling of the plane in the process of such growing is possible only by “golden section” of “right” and “left” spirals.

title	A collaborative project experience in an architectural framework, working with Open Source applications and physical computing [Diseño de Plataformas Digitales e Interactivas: una experiencia educativa trabajando colaborativamente con aplicaciones de Código Abierto y Computación Física]
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	Nowadays, thanks to the telecommunication revolution and therefore the massive spread of Internet, we have seen the come up of international architectural offices with branches located in different continent, working in a collaborative fashion, surpassing physical and time frontiers. At the same time, the multidisciplinary work between designers, architects, engineers, programmers and even biologist, between others, have been taking place in the new network society. All transformations also supported by the arising of FOSS (Free Open Source Software) and the virtual communities behind them, which allow the creation of non-traditional or specific software, the association between disciplines, and also, the formation of meeting scenarios for a mixture of individuals coming up with multiple motivation to coexist in collaborative environment. Furthermore, it is possible to argue that Open Source applications are also the reflection of a social movement, based on the open creation and exchange of information and knowledge. Do the appeared of FOSS compel us to re-think our working and teaching methods? Do they allow new modes of organizing and collaborating inside our architectural practices?. This paper would like to address these questions, by presenting the results of the “Experience Design” course, which by implementing teaching methods based on Open Source principles and cutting-edge tools, seeks to approach students to these new “way of do”, knowledge and methodologies, and overall, focus them on the science behind the computer. This paper describes the “Experience Design” course, in which architectural graduate students of Universidad Diego Portales (Chile), put for first time their hands on the creation of interactive interfaces. By acquiring basic knowledge of programming and physical computing, students built in a collaborative way a responsive physical installation. The course use as applications “Processing” and “Arduino”. The first one is an Open Source programming language and environment for users who want to program images, animation, and interactions. It has a visual context and serve as a software sketchbook and professional production tool. Processing is a project initiated by Ben Fry and Casey Reas, at the MIT Media Lab (www.processing.org). The second is an Open Source electronics prototyping platform based on flexible, easy-to-use hardware and software. Arduino has a microcontroller (programmed with Processing language) which can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators (www.arduino.cc). Both environments shared a growing community of people working in related projects and extending useful assistance for beginners. In this paper it is presented the current state of the pilot course and some of the initials results collected during the process. Students and teacher’s debates and evaluations of the experience have been exposed. Together with a critical evaluation in relation to the accomplishment of the effort of place together different disciplines in one collaborative project akin, architecture, design, programming and electronic. Finally, futures modifications of the course are discussed, together with consideration to take in account at the moment of bring Open Source and programming culture into the student curriculum.

source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This work shows the study of the methods and techniques for the development of a virtual vision VRML 3D included in an "Digitally-integrated knowledge base" with interactive interphases of a significantly revitalized fragment of a central area of the city of Rosario, Province of Santa Fé, Argentina, that includes an emblematic heritage for the Argentineans: the National Monument to the Flag. Digital models that partly allow the development of a hypothesis of integration between the digitized information and information technology—new digital proximity— to the effects of being able to investigate the generation of multimedia database that includes three-dimensional and dynamic models of the mentioned type, in this case, urban, architectonic, and cultural heritage. Different views and research on heritage have been developing. Nevertheless, the use of these new 3D non-immersive technologies and inter-phases are opening a new field of vision and understanding of the subject.

summary	Este trabajo describe el seminario de Diseño Generativo ofrecido en el programa de posgrado en el área de Arquitectura y Construcción en la Universidad de Campinas en el primer semestre de 2008. El curso tuvo como objetivo introducir el tema de los métodos sistemáticos de generación de alternativas de diseño, como base para el desarrollo de sistemas de CAAD. El método pedagógico del curso estuvo compuesto por presentaciones teóricas, lecturas, discusiones, y ejercicios prácticos. Los sistemas generativos más conocidos fueron categorizados en dos grandes grupos: el de combinaciones de elementos (como la enumeración sistemática de combinaciones y los algoritmos genéticos) y el de los sistemas basados en reglas (como los fractales y la gramática de formas). Además de constituirse en una oportunidad para proponer una categorización de los principales sistemas generativos, el curso también permitió que se hiciera una reflexión sobre la importancia de la introducción de los sistemas generativos y de las técnicas de programación en los cursos de pre-grado y pos-grado.

summary	Structure computation can be carried out in the very early steps of architectural design thanks to the generalization of the use of computers. So, architects can be interested by specific computing tools dedicated to mechanical simulations in design process, especially using interactivity. Researches on these kinds of tools are developed by the ARIAM-LAREA team in the Ecole Nationale Supérieure d’Architecture de Paris La Villette, using graphic statics with a dynamic geometry software, finite element method and tensile structure software. The specificities of such tools are presented through historical examples and students projects.

source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	The objective of the present research was to study the use of animation techniques as a tool for the design process. The study started with a literature review about the different possible applications of animation techniques in architectural design. Four main categories of applications were found: (1) space representation and “walk through”, (2) simulation of articulated elements and kinetic structures, (3) visualization and analysis of functional aspects of the buildings, such as circulation and fire escape, and finally (4) the generation of novel shapes. The second part of the research consisted of a design exercise in which animation techniques were used to generate a shape. For this purpose a wind simulator was used in 3DMAX. Next, Paracloud software was used to automatically generate a rib structure that allowed to produce a scale model of the shape with a laser cutter.

summary	Learning Management Systems (LMS) embody spaces that combine Virtual Classrooms, learning communities, repositories of educational resources and communication devices. The use by faculty members and students, in a campus containing the schools of Architecture, Design and Geography, of Open Source LMS MOODLE, during the years 2005-2006, was assessed. An analysis of the Digital Vestiges, the metadata in the logs database, distinguished between the levels of informative and communicational interaction. The results draw attention to a trend, similar to previous measurements in Latin America, of more use of ICT educational resources for informational purposes than communicational interactions between teachers and students.

title	Study of digital morphing tools during the design process - Application of freeware software and of tools in commercial products as well as their integration in AutoCAD
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This research work examines methods of experimental designing with CAAD in a CAD laboratory with architecture students as the testing persons. Thereby the main focus is on the early phase of finding forms, in which different techniques with digital media are tried out in the didactic architectural design lessons. In these work have been traced the influences of the media employed on the design processes and combined the approaches of current CAAD research with aspects from classic design theory. For mathematical rules of proportion, atmospheric influence factors and analogy concepts in architecture, I have developed design methods which have been applied and verified in several series of seminars. (Kirschner, U.: 2000, Thesis, a CAAD supported architectural design teaching, Hamburg, school of arts). Previous experimental exercises showed that morphological sequences of modeling are effective sources for playful designing processes. In the current work these approaches are enhanced and supplemented by different morphological architectural concepts for creating shapes. For this purpose 2D based software like Morphit, Winmorph and other freeware were used. Whereas in the further development of this design technique we used 3D freeware morphing programs like zhu3D or Blender. The resulting morphological shapes were imported in CAD and refined. Ideally the morphing tool is integrated in the modeling environment of the standard software AutoCAD. A digital city model is the starting basis of the design process to guarantee the reference to the reality. The applied design didactic is predicated on the theories of Bernhard Hoesli. The act of designing viewed as „waiting for a good idea“ is, according to him, unteachable; students should, in contrast, learn to judge the „the force of an idea“. On the subject of morphology a form-generating method in the pre-design phase has been tested. Starting from urban-planning lines on an area map, two simple geometric initial images were produced which were merged by means of morphing software. Selected images from this film sequence were extruded with CAAD to produce solid models as sectional drawings. The high motivation of the students and the quality of the design results produced with these simple morphing techniques were the reason for the integration of the artistic and scientific software into the creative shape modeling process with the computer. The students learned in addition to the „bottom up “and „ top down” new design methods. In the presentation the properties and benefits of the morphing tools are presented in tables and are analyzed with regard to the architectural shape generating in an urban context. A catalogue of criteria with the following topics was developed: user friendliness, the ability of integrating the tools or as the case may be the import of data into a CAD environment, the artistic aspects in terms of the flexibility of shape generating as well as the evaluation of the aesthetic consideration of shapes.

summary	Creativity is an important factor for innovators. According to Eguchi and Pinheiro (2008) the basis of design is innovation because of the use creative methodology. It’s important to remember that the word “project” comes from the Latin “proyectus”, meaning “a forward throwing action”. According to Ramos (2006), “educating for creativity is essential.” Beetlestone (2000), De Bono (1993), Munari (1997) and Pawlak (2000) argue that as we’re children we’re curious to find answers to everything, but that traditional schooling brakes the creativity. This research is a methodological test which aims to identify the reasons for student’s selection of specific creative tools used in university projects.

title	D.O.S. Designers on Spot: Communication processes and Learning actions [Processos de Comunicação e Ações de Aprendizagem]
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	D.O.S. Designers on Spot: Communication processes and Learning actions This paper introduces some concepts that have been studied at D.O.S. project as part of the learning and communication actions. These concepts are relevant to the project as they brought to the team some improvements about design experiences based on network communication, as well as some reflections done by designers and researchers in different parts of the world. The project proposed by our research group is part of growing demands for experiments able to explore the Advanced Internet for fast transferring large packages of content. The activities are divided in two different instances: one is called exploratory research and aims to identify enrichments that a collaborative practice would add to the design process and to the production of interactive prototypes as well. The other one is related to remote learning strategies. It aims at investigating new methods of collective design and prototyping of objects with integrated media, and the diffusion of these techniques and methods in classroom environments, as a teaching strategy. Following are three different aspects about design experiences. The first one, called communication processes, presents a panoramic view about different ways the participants of a remote design session can share information. It targets to point and to systematize design actions by exploring transversal characteristics among designers, teams and the resulting objects. In order to achieve it, we have to understand some relations between remote communication and design processes, which explore issues in the project phases of conception, production and interaction. This exploration is part of the search for a conceptual scope for the D.O.S. project development, with an emphasis on the communication specificities between remote designers and the design process. The second one, learning action processes, introduces some issues about academic teaching and learning of design through remote and collaborative media. The third one, Virtual Design Studio (VDS), is related to the previous and aims to present a specific kind of remote design sessions targeting to create strategies to use new communication and information technologies (ICT) on remote project instances. The teaching of Architecture and Design is, above all, multidisciplinary – this means that it is not limited to the knowledge of one field of activity but, by a wide range of subjects from different areas - including Computing. The introduction of ICT (Information and Communication Technologies) in the project process is commonly associated to the final stages, and not to the creation. The contribution of the digital environment is provided for the use of various software, which are not restricted to those responsible for graphical representation: programs responsible for the organization of data in tables, for example, enable monitoring developments with clarity. The multidisciplinary consideration supports new variables in the process of design, working quickly and accurately on the possibilities, which modifies the agency of decisions and management tasks.

summary	This paper aims to discuss the possibilities of interactive displays in architecture´s design, the article starts discussing how the computational methods transformed the way of thinking architecture. Then are presented and analyzed some technologies that can be built into the workshop of the project architecture, among them: opaque and LCD tablets, chambers of immersion, whiteboards and interactive screens and equipment´s of tangible digital information (Tangible Bits). It appears that the trend of technological innovations is a mix of traditional and digital, facilitating the manipulation and production of drawings by architects through direct touch, some of the technologies are already considered viable, providing low cost and good results during the practice of design.

title	From physical models to immersive collaborative environments: testing the best way for homeless people to visualise and negotiate spaces
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This paper describes an experiment to investigate the best way for lay people to use representation to visualise and negotiate space. It was motivated by our observations in workshops for digital inclusion in the context of a housing project for a homeless association. Computers were used to make it easier for the community to understand and change the spaces in real time. The first workshops proved that our approach was efficient as an exercise but not certainly effective concerning the understanding of spatial qualities. So we have designed an experiment to compare the usability of different media in participatory design processes. For that we have adapted the ‘Usability’ methodology, which is fully described in the paper. We started with three main questions. The first concerned the effectiveness of different media to represent spatial quality; the second concerned the best way for novices to approach space, whether by refurbishing a pre-existing space or by starting from the scratch; and the third concerned the effectiveness of negotiation by means of discourse and by means of or action. We also had two main hypothesis: one coming from research on digital environments and stereo visualisation, indicating that the more people feel immersed in the represented environment the more they are able to correlate it with physical space; and the other coming from our own observations in the participatory design workshops, in which the collective decision-making was manipulated by those people with more advanced communication skills who use their ability in an authoritative way regardless of the relevance of what they have to say. This paper describes the whole experiment, which was an exercise of spatial negotiation in 5 versions. In the first version we provided fixed digital views of a room in plan and axonometry; for another two versions we provided a physical model of the room in 1:10 scale, with some pieces of the existing furniture in different scales. This was done to check if people were just playing with a puzzle or actually grasping the correspondence between representation and the object or the space represented. One version proposes refurbishment and the other starts from the scratch. And the last two versions repeated the same task made with the physical model, but this time using a 3D interactive digital model. People were required not only to organise the furniture in the space but also to build a full scale cardboard structure and organise the real furniture reproducing their proposed model. Their comments on the spaces they had built confronted with what they had imaged when working with the model has enabled us to compare the different models, as also the different ways of negotiating spaces. This paper describes this experiment in detail concluding that 3D digital interactive models are far more effective than physical models and 2D drawings; when negotiation happens by means of action it provides more creative results than when the discoursive practice prevails; people are more creative when they start something from scratch, though they spend more time. The results of this experiment led us to formulate a new hypothesis leading to the development of an immersive collaborative environment using stereoscopy.

title	Computing And Manipulation In Design - A Pedagogical Experience Using Symmetry
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	The concept of symmetry has been usually restricted to bilateral symmetry, though in an extended sense it refers to any isometric transformation that maintains a certain shape invariant. Groups of operations such as translation, rotation, reflection and combinations of these originate patterns classified by modern mathematics as point groups, friezes and wallpapers (March and Steadman, 1974). This extended notion represents a tool for the recognition and reproduction of patterns, a primal aspect of the perception, comprehension and description of everything that we see. Another aspect of this process is the perception of shapes, primary and emergent. Primary shapes are the ones explicitly represented and emergent shapes are the ones implicit in the others (Gero and Yan, 1994). Some groups of shapes known as Semantic Shapes are especially meaningful in architecture, expressing visual features so as symmetry, rhythm, movement and balance. The extended understanding of the concept of symmetry might improve the development of cognitive abilities concerning the creation, recognition and meaning of forms and shapes, aspects of visual reasoning involved in the design process. This paper discusses the development of a pedagogical experience concerned with the application of the concept of symmetry in the creative generation of forms using computational tools and manipulation. The experience has been carried out since 1995 with 3rd year architectural design students. For the exploration of compositions based on symmetry operations with computational support we followed a method developed by Celani (2003) comprising the automatic generation and update of symmetry patterns using AutoCAD. The exercises with computational support were combined with other different exercises in each semester. The first approach combined the creation of two-dimensional patterns to their application and to their modeling into three-dimensions. The second approach combined the work with computational support with work with physical models and mirrors and the analysis of the created patterns. And the third approach combined the computational tasks with work with two-dimensional physical shapes and mirrors. The student’s work was analyzed under aspects such as Discretion/ Continuity –the creation of isolated groups of shapes or continuous overlapped patterns; Generation of Meta-Shapes –the emergence of new shapes from the geometrical relation between the generative shape and the structure of the symmetrical arrangement; Modes of Representation –the visual aspects of the generative shape such as color and shading; Visual Reasoning –the derivation of 3D compositions from 2D patterns by their progressive analysis and recognition; Conscious Interaction –the simultaneous creation and analysis of symmetry compositions, whether with computational support or with physical shapes and mirrors. The combined work with computational support and with physical models and mirrors enhanced the students understanding on the extended concept of symmetry. The conscious creation and analysis of the patterns also stimulated the student’s understanding over the different semantic possibilities involved in the exploration of forms and shapes in two or three dimensions. The method allowed the development of both syntactic and semantic aspects of visual reasoning, enhancing the students’ visual repertoire. This constitutes an important strategy in the building of the cognitive abilities used in the architectural design process.

title	What is the state of digital architectural design?

summary	What is the state of digital architectural design? The ubiquity of the computer in architecture can be seen in the many computer based presentations from famous architectural practices. BIM (Building Information Modelling) is the key word and we can see implementations in very ambitious projects all over the world. Glossy magazines show the results of this kind of architecture and predict that this is the future of our profession. But when we go out into the “small world” (in Europe) and talk with architects in small firms, there is a very different reality – at least at the moment. Although they all agree that the computer is crucial for their work, it is a love/hate relationship for many them. Most still use the computer purely as a drafting device and AutoCAD is still the dominant tool. Although many of them agree with the statement that you can use the computer for design, only a minority really use the computer as a design tool in the early design stages. To find out more about the reality of the use of computers in design in “small town Europe” we have been undertaking two different kinds of research over the past 4 years. The first one is an educational experiment using first year’s students to find out about the different qualities of designing with and without the computer. The results have been presented at previous conferences and, since we are doing a last run of these experiments this year, we will update and finalise our findings in this paper. To make it comparable to previous years, we use largely the same settings using the same type of student (first year) and the same project/site. We will also be comparing the results for students designing ‘freestyle’ ie in the way that they want against the previous years controlled groups. The second strand of research we have followed is a survey amongst practitioners and some of the above statements came out of this survey. We did this survey using a web questionnaire and focused on a particular region of Europe. Although the numbers of participants for this survey were quite satisfying we are re-running the survey in a different region and country to see whether there are significant differences. The results of our research and our experience as teachers and architects leads us to the main question of how we can give recommendations on how to teach design the new generation of architects. In many aspects most of the teaching that is done in our faculties is still strictly divided into teaching design and teaching computer skills. The crucial question for architectural education are the implications of the ubiquity of the computer will have especially in the field of design. We will try to give some suggestions for these effects this could have on our teaching. In the long run, this is the only way to avoid some of the pitfalls and bring the benefits of computers in design to our small architectural firms. The paper will present a summary of the results of our research and try to propose an answer to the question: “What is the state of digital design in small town Europe?”

title	A study about facades from historical brazilian town using shape grammar
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	Shape grammars have been used in architecture for analysis and synthesis - in the first case, mainly for the characterization of styles and in the later for the generation of novel compositions. The present research proposes the use of shape grammars for establishing guidelines for the requalification of historical areas that have lost their original characteristics due to improper renovations. The use of shape grammars proposed here starts with the definition of a set of rules for characterizing the original style of an area. Based on these rules, the main characteristics of the area are confirmed, such as siting, proportions between walls and openings in the façades, overall dimensions constraints, and so on. Next, the rules of the grammar are transformed, to allow the use of contemporary building materials, as well as the incorporation of contemporary living styles in the new design. Rules must take into account two cases: original buildings that have been inadequately transformed, and buildings that have been completely torn down and will replace been completely replaced by new constructions. Both cases need to be harmonious with the remaining original buildings, however without simply copying the existing style. In both cases, rules have been used to establish the guidelines for the renovations, which resulted in modern urban environments that resemble the original historical sites in terms of spatial relations and proportions. They also create an appropriate environment for the observations of the preserved original buildings, which would otherwise look like aliens in a completely transformed neighborhood. The latter case is very common in most Brazilian cities, especially in the case of São Paulo, where houses from the late 1800´s and early 1900´s are flanked by high rise apartment buildings. In order to develop and test the proposed method, a study will be carried out in a small Brazilian town called Monte Alegre do Sul. The town was chosen because its original urban morphology, developed in the XIXth century, is still relatively well preserved, although part of the original façades have been transformed. The objective of the research is to develop a shape grammar to set guidelines for the re-adaptation of the already renovated façades and reconstruction of other ones in Monte Alegre do Sul.

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.
