title	La Arquitectura como Extensión Fenotípica Humana - Un Acercamiento Basado en Análisis Computacionales [Architecture as human phenotypic extension – An approach based on computational explorations]

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	The Logic of Architecture: Design, Computation and Cognition
source	The MIT Press, Cambridge
summary	The Logic of Architecture is the first comprehensive, systematic, and modern treatment of the logical foundations of design thinking. It provides a detailed discussion of languages of architectural form, their specification by means of formal grammars, their interpretation, and their role in structuring design thinking. Supplemented by more than 200 original illustrations, The Logic of Architecture reexamines central issues of design theory in the light of recent advances in artificial intelligence, cognitive science, and the theory of computation. The richness of this approach permits sympathetic and constructive analysis of positions developed by a wide range of theorists and philosophers from Socrates to the present. Mitchell first considers how buildings may be described in words and shows how such descriptions may be formalized by the notation of first order predicate calculus. This leads to the idea of a critical language for speaking about the qualities of buildings. Turning to the question of representation by drawings and scale models, Mitchell then develops the notion of design worlds that provide graphic tokens which can be manipulated according to certain grammatical rules. In particular, he shows how domains of graphic compositions possible in a design world may be specified by formal shape grammars. Design worlds and critical languages are connected by showing how such languages may be interpreted in design worlds. Design processes are then viewed as computations in a design world with the objective of satisfying predicates of form and function stated in a critical language.

title	The Computability of Architectural Knowledge
source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 171-185
summary	In an important contribution to the theoretical foundation of design computing, Mitchell noted "an increasingly urgent need to establish a demonstrably sound, comprehensive, rigorously formalized theoretical foundation upon which to base practical software development efforts" (Mitchell, 1986). In this paper we propose such a theoretical framework. A basic assumption of this work is that the advancement of design computing is dependent upon the emergence of a rigorous formulation of knowledge in design. We present a model of knowledge in architectural design which suggests a promising conceptual basis for dealing with knowledge in computer-aided design systems. We require models which can represent the formal knowledge and manipulative operations of the designer in all of their complexity-that is formal models rather than just geometric models. Shape Grammars (Stiny,1980) represent an example of such models, and constitute a relatively high level of design knowledge as compared to, for example, use of symmetry operations to generate simple formal configurations. Building upon an understanding of the classes of design knowledge as the conceptual basis for formal modeling systems may contribute a new realization of the potential of the medium for design. This will require a comprehensive approach to the definition of architectural and design knowledge. We consider here the implications of a well-defined body of architectural and design knowledge for design education and the potential mutual interaction-in a knowledge-rich environment-of design learning and CAAD learning. The computational factors connected with the representation of design knowledge and its integration in design systems are among the key problems of CAAD. Mitchell's model of knowledge in design incorporates formal knowledge in a comprehensive, multi-level, hierarchical structure in which types of knowledge are correlated with computational concepts. In the main focus of this paper we present a structured, multi-level model of design knowledge which we discuss with respect to current architectural theoretical considerations. Finally, we analyze the computational and educational relevance of such models.

title	Deconstructing the Constructivist Drawings of Iakov Chernikhov
source	From Research to Practice [ACADIA Conference Proceedings] Big Sky (Montana - USA) 4-6 October 1990, pp. 61-77
doi	https://doi.org/10.52842/conf.acadia.1990.061
summary	The three-dimensional nature of Chernikhov's Constructivist architecture can be analyzed by a method of reverse perspective deconstruction. After a review and classification of the drawings in Chernikhov's book, 101 Architectural Fantasies, to determine which classes are suitable for deconstruction, the method of perspective deconstruction together with the underlying assumptions is presented and applied to three drawings. Conclusions concerning the forms comprising the architecture depicted in Chernikhov's images and the possibility of representing this Constructivist architecture by shape grammars are discussed.

title	Base de datos de la arquitectura moderna de la ciudad de Maracaibo 1920-1990 [Database of the Modern Architecture of the City of Maracaibo 1920-1990]
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 133-139
summary	Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

title	Logic Programming for Concept Modelling and Support of Urban Housing Design : A Pilot Study
source	1990. 134 p. CADLINE has abstract only
summary	Starting from a case study of manual sketch design of a residential area, the authors develop a prototypical site plan for low to medium density housing. The layout keeps pedestrian and vehicular traffic separated and provides open green area as well as a concentrated urban atmosphere. The constituents of the prototype layout are identified and a system of concepts devised accordingly. This conceptual analysis is formalized, using a Horn clause logic notation. Aspects of the resulting logic model concerning design of walking lines and plazas are refined into a considerable amount of detail. This exercise in knowledge representation seems to indicate that it will be possible, within the logic programming paradigm, to implement computerized support systems able to cooperate with and simulate designers working with architectural design. The main result of the study is that logical analysis of a particular prototype design can result in a collection of quite general concepts which are potentially useful in many other context than that of the prototype, for other kinds of design tasks. The report concludes by recommending several lines or aspects of future research in this area

title	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [Conference Proceedings]
source	International Conference on Computer-Aided Architectural Design 1989/ ISBN 0-262-13254-0] (Massachusetts / USA), 1989, 505 p.
summary	Design is the computation of shape information that is needed to guide fabrication or construction of artifacts. But it is not so straightforward as, say, the computation of numerical information required to balance a checkbook. This is partly because algebras of shapes are not as well understood and precisely formalized as algebras of numbers, partly because the rules for carrying out shape computations tend to be fluid and ill defined and partly because the predicates that must be satisfied to achieve successful termination are often complex and difficult to specify. For centuries architects have carried out shape computations by hand, using informal procedures and the simplest of tools. Over the last two decades though, they have made increasing use of more formal procedures executed by computers. It is still too early to be sure of the gains and losses that follow from this development, but there is no doubt that it raises some challenging questions of architectural theory and some perplexing issues for those concerned with the future of architectural education. This book frames those issues and provides a diversity of perspectives on them. Its contents were initially presented at the CAAD Futures 89 Conference-an international gathering of researchers and teachers in the field of computer-aided architectural design which was jointly sponsored by the Harvard Graduate School of Design and the MIT Department of Architecture and held in Cambridge, Massachusetts, in July 1989. There are four major sections: Theoretical Foundations, Knowledge-Based Design Tools, Information Delivery Systems, and Case Studies: Electronic Media in the Design Studio. In a representative collection of current views, over thirty extensively illustrated papers discuss the experiences of universities in the USA, Europe, Japan, Israel, Canada, and Australia, articulate present theoretical and practical concerns, provide criticism of media and methods, and suggest directions for the future. Architectural educators and architects concerned with the effect of computer technology on the design process will find here an indispensable reference and a rich source of ideas. This book was itself prepared in an electronic design studio. Composition and typography, most image collection and placement, and such editing as was practical within this publishing format, were all performed digitally using Macintosh computers at the Harvard Graduate School of Design during a period of a few weeks in 1989.

doi	https://doi.org/10.52842/conf.ecaade.2021.1.537
summary	This research focuses on the geometric analysis of a project by the architect Marcello D'Olivo, in which the role of parametrization could be a significant part.The first phase was an in-depth study of the compositional syntax of the author, in order to understand the rules adopted by him to design architectures. As he worked between 1950 and 1990, he didn't use digital software for the computation of his projects, but only traditional instruments.The second phase was a description of digital computational procedures to generate models using parametric software. The digitization of some morphologies designed by D'Olivo was converted in shape algorithms.So the aim of the research was to convert his analog procedures into a series of well-defined digital steps, in order to systematize a way to proceed to control complex forms and to attempt to build a bridge between the pencil projects of D'Olivo and parametric design.

title	Saying What It Is by What It Is Like - Describing Shapes Using Line Relationships

summary	Shapes - taken as well-defined collections of lines - are fundamental building blocks in architectural drawings. From doodles to shop drawings, shapes are used to denote ideas and represent elements of design, many of which ultimately translate into actual objects. But because designs evolve, the shapes representing a design are seldom static - instead, they are perpetually open to transformations. And since transformations involve relationships, conventional methods of describing shapes as sets of discrete endpoints may not provide an appropriate foundation for schematic design. This paper begins with a review of the perception of shapes and its significance in design. In particular, it argues that juxtapositions and inter-relationships of shapes are important seedbeds for creative development of designs. It is clear that conventional representation of shapes as sets of discrete lines does not cope with these -emergent" subshapes; the most basic of which arise out of intersecting and colinear lines. Attempts to redress this by using ‘reduction rules’ based on traditional point-and-line data structures are encumbered by computational problems of precision and shape specification. Basically, this means that some ‘close’ cases of sub-shapes may escape detection and their specifications are difficult to use in substitution operations. The paper presents the findings of a computer project - Emergence II - which explored a 'relational' description of shapes based on the concept of construction lines. It builds on the notion that architectural shapes are constructed in a graphic context and that, at a basic compositional level, the context can be set by construction lines. Accordingly, the interface enables the delineation of line segments with reference to pre-established construction lines. This results in a simple data structure where the knowledge of shapes is centralized in a lookup table of all its construction lines rather than dispersed in the specifications of line segments. Taking this approach, the prototype software shows the ease and efficiency of applying ‘reduction rules’ for intersection and colinear conditions, and for finding emergent sub-shapes by simply tracking the construction lines delimiting the ends of line segments.

title	Aspects of design logic and Le Corbusier's universe of forms
source	Harvard University, Graduate School of Design
summary	Generation of form in architectural design tends to become a highly structured process when computational tools are engaged. The objective of this study was to develop an alternative way of designing with a computer--one that is not framed by assumptions of monotonicity and determinism. To realize this aim the case study method was chosen. It was followed by formalization and design etudes rooted in a specific corpus of significant design work. A corpus of work was isolated from Le Corbusier's Oeuvre complete to serve as the vehicle for: (a) Construction, using shape grammar rules of a dynamic model of a concise design world. (b) Analysis of the process of rupture and dialectic which results in the fundamental transformation of the design world. (c) Generation of existing and new examples in the given language. (d) Examination of the limitations of the shape grammar formalism and proposal of alternatives formalisms based on non-monotonic logic. Le Corbusier's purist tradition, selected as the corpus for this study, is characterized by formal continuity followed by a sudden rupture in its formal language. The issue of change and collapse of one design world into a new one was therefore the focus of the investigation. The method that was developed interprets the formal procedure of examining the architectural object as 'reading' and the procedure of generating the architectural object as 'writing'. Design is seen as a continuous feedback loop between reading and writing within the boundaries of a given universe of forms. This is demonstrated by abstracting an architectural vocabulary and compositional rules from Le Corbusier's purist work, translating the vocabulary into a set of computer models, and using the computer to transform and recompose these elements into new designs.

title	Variations in Solids : A Declarative Treatment
source	Computers and Graphics. April, 1990. Vol. 14: 40 p. : ill. includes bibliography
summary	Underlying the notions of variational geometry, design prototypes, features, and representation of assemblies seems to be a common concept of variations. This paper develops the core of a monotonically declarative system for variations on solids. It introduces a set of language constructs that are the basis for ASCEND, an object oriented equation solving language. It presents equations for representing certain spatial relationships between primitive geometric elements. Using plex grammar notation it develops a set of Euler operators that are monotonic in the strict sense required by the ASCEND language. These operators are collectively shown to generate representations for all plane models of 2-manifold objects and to generate only such representations. Finally it presents the core of a system for variations using the ASCEND language to implement both equation models and the new Euler operators

title	Adaptive Mesh Generation for Global Diffuse Illumination
source	Computer Graphics Proc. SIGGRAPH 90 Vol. 24, No. 4, Aug. 1990, pp. 155-164
summary	Rapid developments in the design of algorithms for rendering globally illuminated scenes have taken place in the past five years. Net energy methods such as the hemicube and other radiosity algorithms have become very effective a t computing the energy balance for scenes containing diffusely reflecting objects. Such methods first break up a scene description into a relatively large number of elements, or possibly sev- eral levels of elements. Energy transfers among these ele- ments are then determined using a variety of means. While much progress has been made in the design of energy transfer algorithms, little or no attention has been paid to the proper generation of the mesh of surface elements. This pa- per presents a technique for adaptively creating a mesh of surface elements as the energy transfers are computed. The method allows large numbers of small elements to be placed at parts of the scene where the most active energy trans- fers occur without requiring that other parts of the scene be needlessly subdivided to the same degree. As a result, the computational effort in the energy transfer computations can be concentrated where it has the most effect.

title	A digital Procedure of Building Construction: A practical project

summary	In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

summary	In 1990, due to the traditional architecture design and construction method difficult to build the complicated and non-geometry free-form Fish Structure in Barcelona, architect Frank Gehry started learn from the field of aerospace to utilize CAD/CAM technology in design and manufacture process. He created the free-form fish model in CAD system and exported the digital CAD model data to CAM machine (RP and CNC) to fabricate the design components, and finally assembled on the site. Gehry pioneered in the new digital design process in using CAD/CAM technology or so-called digital fabrication. It becomes an important issue recently as the CAD/CAM technology progressively act as the new digital design media in architectural design and construction process (Ryder et al., 2002; Kolarevic, 2003). Furthermore, in the field of architecture professional, some commercial computer systems had been developed on purpose of standardizes the digital design process in using CAD/CAM fabrication such as Gehry Technologies formed by Gehry Partners; SmartGeometry Group in Europe and Objectile proposed by Bernard Cache. Researchers in the research field like Mark Burry, Larry Sass, Branko Kolarevic, Schodek and others are enthusiastic about the exploration of the role of CAD/CAM fabrication as new design media in design process (Burry, 2002; Schodek et al., 2005; Lee, 2005).

summary	The paper presents views and ideas on how building models can be build and on their properties as well as example on available software. Examples are also given from projects carried through in the KBS-MEDIA environment at Lund University where demonstrators have been built to support different phases in the building process: Building maintenance; material and vendors information; city advisor, etc. In this environment new concepts and tools are tried out in connection with using, building and maintaining the systems formed by advanced software and new media. New tools for building and using the systems have been defined, created and tested

title	Messina 1908: The Invisible City

summary	The initial purposes of this work were to build a 3D model of the old city of Messina and to reconstruct a walk through it; to understand the "Ghost city," the parts that form it, and the rules of its plan, which are explicit in some cases but hidden most of the time; to measure its space, appreciate the similarities to and differences from modern city plans, and use the information to improve the plans of tomorrow. It might seem a useless study of a nonexistent city, and yet during the months of detailed work, of patient reconstruction from the surveys and photographs of the city destroyed in 1908, we began to consider how it was still possible to obtain spatial values of and to project behaviors in the lost city, in other words, to practice tests on memory that are very interesting for people working in a context in which memory no longer exists. The work presented here is the first stage of a more complex research project still to be carried out on Messina as it was at the end of the nineteenth century. Here we constructed a 3D model of some parts of the city prior to the earthquake of 1908 and made a five-minute video, using cartoon techniques, of an "impossible" walk through the city. The fragments of the city were reconstructed from available documentary sources, primarily photographic images, which tended to be of the most important places in the city.
