title	Between Mediation and Making CIMSp: A Technoètic Modus Operandi

summary	The following paper describes an ongoing research project whose goal is to define a scalable, hybrid production and deployment protocol (CIMSp) for the creation of virtual environments (VE). Ultimately, the aim is to establish a creative workflow and infrastructure that embodies architectural and urban design activity as practiced by the research unit. The objective of the present paper is to schematically outline the current state of the research and its practical and theoretical context for further development. A theoretical position will be stated which assumes that the content, tool, epistemological, and speculative realms are consubstantial (technoèsis). The practical endeavour is to create the informational and embodied temporal--spatial condition of possibility for the imaginative production of cultural artifacts. It must accommodate varying individual and collaborative forms and styles of making and no presumption of a self-enclosed and referential system is made. A critical position is particularly compelling when this production is immersed in technological modalities of making where information and embodiment are inextricably intertwined. CIMSp is based on the workflow from acquisition and creation to output and storage. The work environment is comprised of a select set of software applications and visualization technologies. Secondly, an XML-based content and information management system is under construction to ensure project quality control, rigorous documentation practices, and bi-directional knowledge feedback procedures to enable an effective and resource-full workflow. Lastly, scalability of output modalities for use in the design process and for final presentation from WWW deployment to a high-resolution collaborative work environment (CWE) is being developed. The protocol is a multiuser mode of creation and production that aims to transform the technologies and their interrelation, thus dramatically impacting the creative process and intended content. It is a digital production workflow that embodies intensive visualization criteria demanded by the end users. The theoretical and practical intention of CIMSp is to provisionally structure the collaborative creative process and enable a choreographed movement between the realms of the technologically mediated and made in the pursuit of significant digital content creation.

title	SGML: a meta-language for shape grammars
source	PhD dissertation, Department of Architecture, Massachusetts Institute of Technology, Cambridge, Mass
summary	A shape grammar develops a drawing through a series of transformations by repeatedly applying if-then rules. Although the rules can be designed, in principle, to construct any type of drawing, the drawings they construct may not necessarily develop in the manner intended by the designer of the grammar. In this thesis, I introduce a shape grammar meta-language that adds power to grammars based on the shape grammar language. Using the shape grammar meta-language, the author of a grammar can: (1) explicitly determine the sequence in which a set of rules is applied; (2) restrict rule application through a filtering process; and (3) use context to guide the rule matching process, all of which provide a guided design experience for the user of the grammar. Three example grammars demonstrate the effectiveness of the meta-language. The first example is the Bilateral Grid grammar which demonstrates how the meta-language facilitates the development of grammars that offer users multiple design choices. The second grammar is the Hexagon Path grammar which demonstrates how the metalanguage is useful in contexts other than architectural design. The third and most ambitious example is the Durand grammar which embodies the floor plan design process described in Précis of the Lectures of Architecture, written by JNL Durand, an eighteenth century architectural educator. Durand's floor plan design process develops a plan through a series of transformations from grid to axis to parti to wall. The corresponding Durand grammar, which consists of 74 rules and 15 macros organized into eight stages, captures Durand's ideas and fills in gaps in Durand's description of his process. A key contribution of this thesis is the seven descriptors that constitute the meta-language. The descriptors are used in grammar rules: (1) to organize a set of rules for the user to choose from; (2) to group together a series of rules; (3) to filter information in a drawing; (4) to constrain where a rule can apply; and (5) to control how a rule is applied. The end result is a language that allows the author to create grammars that guide users by carefully controlling the design process in the manner intended by the author.

title	Generative Process of Oskar Niemeyer‘s Style
source	2005 Aesthetics and Architectural Composition. Proceedings of the Dresden International Symposium of Architecture 2004 (to appear in "pro Literatur Verlag", D-82291 Mammendorf ISBN: 3-86611-022-7 / Editors: Ralf Weber/Matthias Albrecht Amann/ TU Dresden
summary	The aim of this study is to outline the structure of a possible grammar of Oscar Niemeyer’s architectural language, focusing on the so-called “free forms.” The idea is to assess the extent to which it is possible to shed some light on the discussion of architectural freedom as used by many authors when describing the work of the Brazilian architect. The investigation associates geometric relations present in Niemeyer’s buildings to the Shape Grammar model as proposed by Stiny & Gips (1975). The model made possible the depiction of consistencies in vocabulary, rules and operations deployed by Niemeyer. This eventually led to the description of an original architectural language present in Niemeyer’s buildings.

summary	Virtual and Augmented Reality have become common tools in the architectural design process. This technology assists all participants in gaining planning certainty. To interact with the digital models, different input methods are used and adapted by the authors like keyboard, on screen menu, tangible interface, tablet PC and PDA. While every input method has certain advantages and disadvantages, currently tablet PC and PDA best cover the users’ general needs. A usability test shows that reviews with tablet PC are faster compared to other interfaces.

summary	The development of architectural design systems that describe fully the form, structure and behaviour of a design relies heavily on the incorporation of intelligence in the representations, analyses, transformations and transactions used by the computer. Traditionally such intelligence takes either of two forms. The first is a methodical framework that guides actions supported by the design system (usually in a top-down fashion). The second is local, intelligence mechanisms that resolve discrete, relatively well-defined subproblems (often with limited if any user intervention). Local intelligent mechanisms offer the means for adaptability and transformability in architectural design systems, including the localization of global tendencies. This refers both to the digital design technologies and to the historical, cultural and contextual modifications of design styles and approaches.

doi	https://doi.org/10.52842/conf.caadria.2004.253
summary	Digitally supported space-planning techniques have been researched and developed for decades. By processing space adjacency data with existing space-planning techniques, an objective space relationship diagram or schematic layout can be produced. These results represent the functional aspect of each project, which can be used as a reference for further design development. With these results, designers can enhance plan layouts with the preferences established by their client or themselves, as well as design styles. In this research, the author proposes a new method of applying personal preference to modify the objective layout, which imitates human interacting behavior as space organizing categories, Space Character.

title	Design Generation of the Central Asian Caravanserai
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	Challenges for the study of Islamic architecture include its abundance and diversity in expression and its classification based on distinct functional or stylistic types. We address these issues by presenting shape grammars as a methodology for the analysis and design generation of Islamic architecture, with a specific example in the form of a parametric shape grammar for central Asian caravanserais. The grammar is developed by identifying distinct design types. Shape rules are created based on a study of the spatial elements and their organisation in the designs. We illustrate the utility of the grammar by deriving an extant design and as well as, previously unknown designs. We conclude by discussing possible extensions to the current grammar and future work involving the development of a grammar based framework for the comparative analysis of medieval Islamic courtyard buildings.

title	La Arquitectura como Extensión Fenotípica Humana - Un Acercamiento Basado en Análisis Computacionales [Architecture as human phenotypic extension – An approach based on computational explorations]
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 56-60
summary	The study describes some of the aspects tackled within a current Ph.D. research where architectural applications of constructive, structural and organization processes existing in biological systems are considered. The present information processing capacity of computers and the specific software development have allowed creating a bridge between two holistic nature disciplines: architecture and biology. The crossover between those disciplines entails a methodological paradigm change towards a new one based on the dynamical aspects of forms and compositions. Recent studies about artificial-natural intelligence (Hawkins, 2004) and developmental-evolutionary biology (Maturana, 2004) have added fundamental knowledge about the role of the analogy in the creative process and the relationship between forms and functions. The dimensions and restrictions of the Evo-Devo concepts are analyzed, developed and tested by software that combines parametric geometries, L-systems (Lindenmayer, 1990), shape-grammars (Stiny and Gips, 1971) and evolutionary algorithms (Holland, 1975) as a way of testing new architectural solutions within computable environments. It is pondered Lamarck´s (1744-1829) and Weismann (1834-1914) theoretical approaches to evolution where can be found significant opposing views. Lamarck´s theory assumes that an individual effort towards a specific evolutionary goal can cause change to descendents. On the other hand, Weismann defended that the germ cells are not affected by anything the body learns or any ability it acquires during its life, and cannot pass this information on to the next generation; this is called the Weismann barrier. Lamarck’s widely rejected theory has recently found a new place in artificial and natural intelligence researches as a valid explanation to some aspects of the human knowledge evolution phenomena, that is, the deliberate change of paradigms in the intentional research of solutions. As well as the analogy between genetics and architecture (Estévez and Shu, 2000) is useful in order to understand and program emergent complexity phenomena (Hopfield, 1982) for architectural solutions, also the consideration of architecture as a product of a human extended phenotype can help us to understand better its cultural dimension.

title	Combing Grammars and Space Syntax: Formulating, Generating and Evaluating Designs
source	International Journal of Architectural Computing vol. 2 - no. 4, 492-515
summary	This paper is concerned with how two different computational approaches to design – shape grammars and space syntax – can be combined into a single common framework for formulating, generating, and evaluating designs. The main goal is to explore how the formal principles applied in the design process interact with the spatial properties of the designed objects. Results suggest that space syntax is (1) useful in determining the universe of solutions generated by the grammar and (2) in evaluating the evolving designs in terms of spatial properties and, therefore, in guiding the generation of designs.

summary	This work examines the means by which design software is created, from a designer’s - rather than a programmer’s - viewpoint, through the specific example of Shaper2D. Shaper2D employs an intuitive, visual interface that encourages a „learning by designing“ approach to shape grammar education.

source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 195-200
doi	https://doi.org/10.52842/conf.ecaade.2004.195
summary	The rise of design computation as a paradigm in design process has certainly brought increased attention to the mathematical basis of form giving in architectural design. Numerous types of generative systems ranging from shape grammars to parametric design have been developed in the past, where computers are used as a tool to generate building form automatically. This paper focuses on the role of number sequences and mathematical methods of controlling and introducing systematic change (modulation) to generative systems. In a graduate level class, VBA programming through a CAD system was used to develop software that can parametrically generate 2-d and 3-d forms. As a conclusion, the paper argues that forms generated as such are not monotonous, and that being particularly attentive to the mathematical basis of variation and change in parametric generators allows one to explore change in a more systematic fashion.

doi	https://doi.org/10.52842/conf.acadia.2004
summary	We are presenting design ideas, technical innovation, and fabrication expertise that address crucial issues. Authors investigate how to effectively design and practice architecture with automated prototyping and manufacturing. We want to understand where this might lead, and how it might change the nature of architecture itself. We are just beginning to discover the opportunities to be found in integrating automated fabrication within the practice of architecture. At the same time, the new century has brought very mixed perspectives on confident Modern progress. A cautious scrutiny of 'innovation' is needed. Fabrication is an old word with the straightforward meaning, to make. The roots of the word lead to the origins of architecture. Making has been considered a virtue by ancient writers and modern politicians alike. Fabrication (and homo faber, 'one who makes') have served as fundamental terms that constitutions and contract laws have been built upon. Shaping and working with materials is at the core of Western civilization. However at a point in human history where nature is steadily being replaced by human artifice, the consequences of making are far from simple. Whether for good or ill, our new fabricated environment is transforming the world.

title	View from the Road: Environmental Simulation for the Fractal City of Rhine Ruhr
source	Spatial Simulation and Evaluation - New Tools in Architectural and Urban Design [Proceedings of the 6th European Architectural Endoscopy Association Conference / ISBN 80-227-2088-7], pp. 43-47
summary	Highway seems to be more an issue of traffic planning than of urban design. But the highway can be a very important factor for the modern city pattern. Highways shape the spatial form of the fractal city. The modern highway can define new cores outside and “interior edges” within the city. Seen as a planning tool, highways are the great neglected opportunity in city and regional design. The 1st Architecture Biennial, 1ab, taking place from May 2003 to July 2003 in Rotterdam, explores the creative potentials of modern highways worldwide. An international research team discovered the spatial functions of highways in modern agglomerations. This lecture will give an overview of the results of the worldwide analyses and the design projects that had been undertaken. Both authors are members of the German research team. The German team examined the A 42 running through the Ruhrgebiet, a former coal and steal area in western Germany. The Ruhr Area is converting from an industrially orientated region to an agglomeration of high technology and science. But the regional image remains the same due to the fact that the changes cannot be seen, neither physically, nor from the road. Here, the highway could be used as a catalyst supporting and structuring the spatial changes to make them more legible for the people of Rhine-Ruhr. The nature becomes the most important tool of highway design. Landscape forms a linkage between the different cities of the region. Together with the A 40 and other local highways the region becomes the most important (and largest) public space of the new Rhine-Ruhr. The highway seen as a work of urban art can be designed only from the perspective of the driving car.

summary	This paper aims at introducing the main aspects of a research on architectural representation and the usage of new technologies in the process of development of an architectural project, which has been conducted at a department of Graphical Expression. The authors of this paper would like to outline the most excellent and innovating aspects introduced by a number of architectural proposals which involve actively the application of these techniques. The chosen case studies for this paper are among the European contemporary architectural panorama. The authors will analyze some projects of architectural studios which were involved in the urban transformation brought about by celebration of the Forum of the Cultures 2004. These new ways of architectural representation have had, in this specific case, a significant effect within the context of a technological revolution that allows the conception of new forms and textures and the reflection on the increasingly complex processes to generate architectural space.

summary	This paper integrates the investigations developed by the authors at Nomads.USP, where we proposes amplify the understanding circa the possible interfaces between the complex thought and the contemporary design process of concrete, hybrid, symbiotic and virtual spaces, through the reading and critical analyses of complex thought principles, over the trandisciplinary methodology. The goal of this project stage is to study alternatives to the conventional design process in architecture, searching possible inter-relations, and complementation, among diverse disciplines, by a transdisciplinary approach of the design process, permeated by the new Information and Communication Technologies [ICT]. Starting from these parameters we search contemporary design processes . developed and applied at the most diverse disciplines . that, by some manner, dialogue with this thought. Inside this context, two processes, defining as Software Engineering Paradigms, deserve special attention: Spiral model and Chaos model.

This article analyzes the specific experience of the Virtual Studio .Habitar a Cidade., in opposition to the concept of a VDS and in a comparative perspective to another VDS experience already carried in the past, in order to identify common issues and specific aspects that differentiate them. It also discusses how much methodological questions are determinant in a VDS and how, in academic virtual studios, this aspect can be more significant than the technological ones. This is especially important considering the technological limitations, related to the economic limitations of Brazilian universities and society.

summary	Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.
