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.

summary Design is the computation of shape information that is needed to guide fabrication or construction of an artifact. This information normally specifies artifact topology (connections of vertices, edges, surfaces, and closed volumes), dimensions, angles, and tolerances on dimensions and angles. There may also be associations of symbols with subshapes to specify material and other such properties. The process of design takes different forms in different contexts, but the most usual computational operations are transformations (unary operations) and combinations (binary operations) of shapes in a two-dimensional drawing or a three-dimensional geometric model. An initial vocabulary of shapes, together with a repertoire of shape transformation and combination operators., establishes the shape algebra within which the computation takes place. The computation terminates successfully when it can be shown that certain predicates are satisfied by a shape produced by recursively applying the transformation and combination operators to the initial vocabulary. These predicates are usually stated in symbolic (verbal or numerical) form. Thus determination of whether a predicate is satisfied usually involves producing a numerical or verbal interpretation of a drawing, then deriving inferences from this interpretation by applying rules or formulae.

summary The objective of this paper is to compare the computational concepts present in three books published by Mitchell between 1987 and 1990: The art of computer-graphics programming (1987), which has Robin Liggett and Thomas Kvan as co-authors, The logic of architecture (1990), probably his most influential work, and The poetics of gardens (1988), which has Charles Moore and William Turnbull as coauthors. By looking at the concepts that are presented in the three books and establishing a comparison between them, we expect to show that The poetics of Gardens should not be seen as a detour from Mitchell´s line of research, but rather as a key piece for understanding the relationship between technology, meaning and logic in his very coherent body of work.

summary In the conventional way of teaching architecture, it is common to think of design as the final synthesis of an intellectual process (composizione in Italian) integrating different elements from different curriculum subjects: history, structural analysis., technology, regional and urban planning, and so on. These elements, being comprehensive of their specific domains, together build the project. This process is supported by a long traditional that cannot easily be modified; however, we must not consider it to be the only one. Architectural practice should be much more. The Scuole di Architettura has walked a long and difficult road in the last thirty years., with a significant widening of interest in social, political, and economic issues. There have been recurring attempts at epistemological reformulation in some areas. There has been an acknowledgment of a crisis in contemporary town planning and a dimming of several certitudes that had developed with the birth and growth of the modernist school. And there has been a weakening of the promises that had given life to the vigorous discussion about town and regional planning. All of this leads to a reconsideration of the meaning and the deeper assumptions that the project implies, a question mark at the center of the human sciences that architectural practice involves. The old tradition., which assigned composition a central role in the project, is no longer sufficient because it is related to a reductive reading of epistemology that views human sciences as defining segments of physical knowledge of the actual world. Contemporary reflection on the difference between understanding and unfolding, together with the attention given to interpreting a moment as compared to purely describing one, gives to the project the task of inquiry instead of solution.

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 Virtual Reality and the Future of Publishing Archaeological Excavations: the multimedia publication of the prehistoric settlement on Tsoungiza at Ancient Nemea
source New York: The Metropolitan Museum of Art
summary The Nemea Valley Archaeological Project is a study of settlement and land use in a regional valley system in Greece extending from the Upper Paleolithic until the present. Active field research was conducted by four teams between 1981 and 1990. The first component was a regional archaeological survey. Second, and closely related to the first, was a social anthropological study of modern settlement and land use. Next was a team assigned to excavate the succession of prehistoric settlements of Ancient Nemea on Tsoungiza. Last, historical ecologists, a palynologist, and a geologist formed the environmental component of the research. As a result of advances in electronic publishing, plans for the final publication of the Nemea Valley Archaeological Project have evolved. Complete publication of the excavation of the prehistoric settlements of Ancient Nemea on Tsoungiza will appear in an interactive multimedia format on CD/DVD in Fall 2000. This project is planned to be the first electronic publication of the American School of Classical Studies at Athens. We have chosen to publish in electronic format because it will meet the needs and interests of a wider audience, including avocational archaeologists, advanced high school and college students, graduate students, and professional archaeologists. The multimedia format on CD/DVD will permit the inclusion of text, databases, color and black-and-white images, two and three-dimensional graphics, and videos. This publication is being developed in cooperation with Learning Sites, Inc., which specializes in interactive three-dimensional reconstructions of ancient worlds http://www.learningsites.com. The Nemea Valley Archaeological Project is particularly well prepared for the shift towards electronic publishing because the project's field records were designed for and entered in computer databases from the inception of the project. Attention to recording precise locational information for all excavated objects enables us to place reconstructions of objects in their reconstructed architectural settings. Three-dimensional images of architectural remains and associated features will appear both as excavated and as reconstructed. Viewers will be able to navigate these images through the use of virtual reality. Viewers will also be able to reference all original drawings, photographs, and descriptions of the reconstructed architecture and objects. In this way a large audience will be able to view architectural remains, artifacts, and information that are otherwise inaccessible.

source Proceedings of the 3rd European Full-Scale Modelling Conference / ISBN 91-7740044-5 / Lund (Sweden) 13-16 September 1990, pp. 10-11
summary The workshop is an institution, available for use by the public and established at the Laboratory of Housing in the Art Academy's school of Architecture for a 3 year trial period beginning April 1985. This resumé contains brief descriptions of a variety of representative model projects and an overview of all projects carried out so far, including the pilot projects from 1983 and planned projects to and including January 1987. The Full Scale Model Workshop builds full size models of buildings, rooms and parts of buildings. The purpose of the Full Scale Model Workshop is to promote communication among building's users. The workshop is a tool in an attempt to build bridges between theory and practice in research, experimentation and communication of research results. New ideas and experiments of various sorts can be tried out cheaply, quickly and efficiently through the building of full scale models. Changes can be done on the spot as a planned part of the project and on the basis of ideas and experiments achieved through the model work itself. Buildings and their space can thus be communicated directly to all involved persons, regardless of technical background or training in evaluation of building projects.

title Interactive design of parameterized 3D models by direct manipulation
source Delft University of Technology
summary The practical applicability of a computer-aided design system is strongly influenced by both the user interface and the internal model representation. A well designed user interface facilitates the communication with the system by offering an intuitive environment for for specification and representation of model information. An internal model representation, capable of storing geometric, topological and hierarchical dependencies between components in a model, increases the efficiency of the system by facilitating modification and elaboration of the model during the different stages of the design process. The subject of this thesis is the integration of a high level parameterized model representation with direct manipulation interface techniques for the design of three-dimensional objects. A direct manipulation interface enables the user to specify a model by interaction on a graphical representation, as an alternative for an abstract and error-prone apha-numerical dialogue style. A high level model representation is obtained by using a procedural modeling language with general purpose control structures, including arithmetic and logical expressions, repetition, conditionals, functions and procedures, and dedicated data types such as coordinate systems, geometric primitives and geometric constraints. The language interpreter is interconnected with a graphical interface, an incremental constraint solver and a geometrical modeler, using visual programming techniques. The developed techniques are implemented in a modeling system called GeoNode. The system incorporates paradigms of object-oriented design, with respect to both the user interface and to the system implementation. The applicability of the presented techniques is illustrated by examples in application domains such as solid modeling, kinematic analysis, feature modeling and top-down design.

summary It has been said that "The beginning of architecture is empty space." (Mitchell 1990) This statement typifies a design education philosophy in which the concepts of space and form are separated and defined respectively as the negative and positive of the physical world, a world where solid objects exist and void-the mere absence of substance-is a surrounding atmospheric emptiness. Since the beginning of the nineteenth century, however, there has been an alternative concept of space as a continuum: that there is a continuously modified surface between the pressures of form and space in which the shape of the space in our lungs is directly connected to the shape of the space within which we exist. (Porter 1979). The nature of the task of representing architecture alters to reflect the state of architectural understanding at each period of time. The construction of architectural space and form represents a fundamental achievement of humans in their environment and has always involved effort and materials requiring careful planning, preparation, and forethought. In architecture there is a necessary conversion to that which is habitable, experiential, and functional from an abstraction in an entirely different medium. It is often an imperfect procedure that centers on the translation rather than the actual design. Design of the built environment is an art of distinctions within the continuum of space, for example: between solid and void, interior and exterior, light and dark, or warm and cold. It is concerned with the physical organization and articulation of space. The amount and shape of the void contained and generated by the building create the fabric and substance of the built environment. Architecture as a design discipline, therefore, can be considered as a creative expression of the coexistence of form and space on a human scale. As Frank Ching writes in Architecture: Form, Space, and Order, "These elements of form and space are the critical means of architecture. While the utilitarian concerns of function and use can be relatively short lived, and symbolic interpretations can vary from age to age, these primary elements of form and space comprise timeless and fundamental vocabulary of the architectural designer." (1979)

title The Art of Human-Computer Interface Design
source New York: Addison-Wesley.
summary Human-computer interface design is a new discipline. So new in fact, that Alan Kay of Apple Computer quipped that people "are not sure whether they should order it by the yard or the ton"! Irrespective of the measure, interface design is gradually emerging as a much-needed and timely approach to reducing the awkwardness and inconveniences of human-computer interaction. "Increased cognitive load", "bewildered and tired users" - these are the byproducts of the "plethora of options and the interface conventions" faced by computer users. Originally, computers were "designed by engineers, for engineers". Little or no attention was, or needed to be, paid to the interface. However, the pervasive use of the personal computer and the increasing number and variety of applications and programs has given rise to a need to focus on the "cognitive locus of human-computer interaction" i.e. the interface. What is the interface? Laurel defines the interface as a "contact surface" that "reflects the physical properties of the interactors, the functions to be performed, and the balance of power and control." (p.xiii) Incorporated into her definition are the "cognitive and emotional aspects of the user's experience". In a very basic sense, the interface is "the place where contact between two entities occurs." (p.xii) Doorknobs, steering wheels, spacesuits-these are all interfaces. The greater the difference between the two entities, the greater the need for a well-designed interface. In this case, the two very different entities are computers and humans. Human-conputer interface design looks at how we can lessen the effects of these differences. This means, for Laurel, empowering users by providing them with ease of use. "How can we think about it so that the interfaces we design will empower users?" "What does the user want to do?" These are the questions Laurel believes must be asked by designers. These are the questions addressed directly and indirectly by the approximately 50 contributors to The Art of Human-Computer Interface Design. In spite of the large number of contributors to the book and the wide range of fields with which they are associated, there is a broad consensus on how interfaces can be designed for empowerment and ease of use. User testing, user contexts, user tasks, user needs, user control: these terms appear throughout the book and suggest ways in which design might focus less on the technology and more on the user. With this perspective in mind, contributor D. Norman argues that computer interfaces should be designed so that the user interacts more with the task and less with the machine. Such interfaces "blend with the task", and "make tools invisible" so that "the technology is subervient to that goal". Sellen and Nicol insist on the need for interfaces that are 'simple', 'self-explanatory', 'adaptive' and 'supportive'. Contributors Vertelney and Grudin are interested in interfaces that support the contexts in which many users work. They consider ways in which group-oriented tasks and collaborative efforts can be supported and aided by the particular design of the interface. Mountford equates ease of use with understating the interface: "The art and science of interface design depends largely on making the transaction with the computer as transparent as possible in order to minimize the burden on the user".(p.248) Mountford also believes in "making computers more powerful extensions of our natural capabilities and goals" by offering the user a "richer sensory environment". One way this can be achieved according to Saloman is through creative use of colour. Saloman notes that colour can not only impart information but that it can be a useful mnemonic device to create associations. A richer sensory environment can also be achieved through use of sound, natural speech recognition, graphics, gesture input devices, animation, video, optical media and through what Blake refers to as "hybrid systems". These systems include additional interface features to control components such as optical disks, videotape, speech digitizers and a range of devices that support "whole user tasks". Rich sensory environments are often characteristic of game interfaces which rely heavily on sound and graphics. Crawford believes we have a lot to learn from the design of games and that they incorporate "sound concepts of user interface design". He argues that "games operate in a more demanding user-interface universe than other applications" since they must be both "fun" and "functional".

summary Phidias is software which integrates computer-aided design graphics with hypermedia to create a hypermedia CAD - or hyperCAD - system. Phidias allows architects to develop building form while having immediate and nearly effortless access to a rich store of textual, numerical, and graphical information. This information access can make a wide variety of design literature and research findings available to architects in a way and at a time that they can easily use it. Thus, Phidias is intended to help bridge the gap between architectural research and practice.

summary Traditionally, communication during the various stages of the building process takes place via drawings of floor plans, elevations, perspectives and scale models. Computerized drawing techniques have recently come into use. Ways of presenting designs have increasingly become of far-reaching importance in current architecture. Nowadays architectural firms employ specialists who are familiar with the latest developments in the field of presentation techniques, or they farm this highly significant part of their job out to gifted designers. Some of the new techniques being developed endeavor to provide a more realistic presentation of designs of housing estates. Apart from new drawing techniques, mention should also be made of the endoscope, an instrument which can simulate an eye-level tour around a scale model while recording it on videotape. Realistic representations differ quite a lot from the conventional architectural presentation techniques applied, which require a larger amount of imagination on the part of the onlookers. The afore mentioned architectural notation systems, on the one hand, can only be understood by experts, in spite of added explanatory signs and symbols. The often used models and artist’s impressions, on the other hand, frequently create a somewhat distorted view, due to lack of concern for spatial proportions. As a consequence, the design presented and the actual architectural realisation may turn out to differ widely. To bridge the widening gap between the experts and the users, clients and government officials, research concerning architectural representation is needed. In 1990 a Dutch scientific journal, issued by The Delft University, published an illustrated report of research findings under the title Overdracht en Simulatie (Information and Simulation). The article gives a description of a pilot study carried out by a research team (Van Der Does, Van Haaften, Kegel and Vrins) to assess and evaluate various presentation techniques used in architecture. This study was just a first step towards a more detailed follow-up study, to which I shall come back after having given a summarized view of the pilot study.

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 Component Based Computer Aided Learning for Students of Architecture and Civil Engineering

summary The paper describes the methodology and the current efforts to develop an interdisciplinary computer aided learning system for architects and civil engineers. The system being developed incorporates a component oriented relational database with an existing interactive 3-dimensional modeling system developed in the School of Architecture and Planning at SUNY Buffalo. The software will be used in existing courses in architecture and civil engineering as a teaching aid to help students understand the complex 3-dimensional interrelationships of structural components. Initial implementation has focused on the modeling of the components and assemblies for a lowrise steel frame structure. Current implementation efforts are focusing on the capability to view connections in various ways including the ability to "explode" a connection to better understand the sequence of construction and load paths. Appropriate codes, limit states of failure and specific data will be linked to each specific component in an expert system shell so that the system can offer feedback about a student generated connection and perhaps offer other possible connections a library of standard connections. Future expansion of the system will include adding other "systems" of a building, such as mechanical, electrical, plumbing, enclosure etc., to help students visualize the integration of the various parts.

title A Hypermedia Model for Supporting Energy Design in Buildings

summary Several studies have discussed the limitations of the available CAAD tools and have proposed solutions [Brown and Novitski 1987, Brown 1990, Degelman and Kim 1988, Schuman et al 1988]. The lack of integration between the different tasks that these programs address and the design process is a major problem. Schuman et al [1988] argued that in architectural design many issues must be considered simultaneously before the synthesis of a final product can take place. Studies by Brown and Novitski [1987] and Brown [1990] discussed the difficulties involved with integrating technical considerations in the creative architectural process. One aspect of the problem is the neglect of technical factors during the initial phase of the design that, as the authors argued, results from changing the work environment and the laborious nature of the design process. Many of the current programs require the user to input a great deal of numerical values that are needed for the energy analysis. Although there are some programs that attempt to assist the user by setting default values, these programs distract the user with their extensive arrays of data. The appropriate design tool is the one that helps the user to easily view the principal components of the building design and specify their behaviors and interactions. Data abstraction and information parsimony are the key concepts in developing a successful design tool. Three different approaches for developing an appropriate CAAD tool were found in the literature. Although there are several similarities among them, each is unique in solving certain aspects of the problem. Brown and Novitski [1987] emphasize the learning factor of the tool as well as its highly graphical user interface. Degelman and Kim [1988] emphasize knowledge acquisition and the provision of simulation modules. The Windows and Daylighting Group of Lawrence Berkeley Laboratory (LBL) emphasizes the dynamic structuring of information, the intelligent linking of data, the integrity of the different issues of design and the design process, and the extensive use of images [Schuman et al 19881, these attributes incidentally define the word hypermedia. The LBL model, which uses hypermedia, seems to be the more promising direction for this type of research. However, there is still a need to establish a new model that integrates all aspects of the problem. The areas in which the present research departs from the LBL model can be listed as follows: it acknowledges the necessity of regarding the user as the center of the CAAD tool design, it develops a model that is based on one of the high level theories of human-computer interaction, and it develops a prototype tool that conforms to the model.
