summary The virtual reconstruction of the archeological site of Madinat al-Zahra. in Córdoba (Spain) has permitted a new approach to the study and comprehension of this palatine city as well as to the typologies of Islamic architecture in Al-Andalus during the 10th century. Starting from fieldwork and from a photogrammetric survey of the site, the digital model has become a highly qualified tool in the research process. Through virtual navigation, it allows to learn new aspects about spatial configuration of this characteristic constructions that configure the basis for the development of further architectures during the following centuries. Furthermore, being conscious that knowledge is basic for cultural heritage preservation, this 3D reconstruction model is an important instrument for general dissemination and for implementing a visit to this significant case of Islamic architecture in Spain.

title LOS "SPIROSPACES"
source Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 179-187.
summary This paper deals with “Spirospaces”. These are a conversion to the third dimension of the two dimensional geometric entities called “Spirolaterals”.

Abelson, Harold, diSessa and Andera (1968) gave the first rules concerning Spirolaterals. To obtain a Spirolateral from a set of straight lines, the first of them must be one unit long and the following must be incremented one unit at each step, at the same time that they turn in a constant direction. Odds (1973) establish the variation of the rotation direction, either to the left or the right. However, he did not give a mathematical relation able to calculate open Spirolaterals. Krawczyk (2001) developed a computer program that generates Spirolaterals following the method suggested by Abelson. These are Spirolaterals obtained by enumeration without a predictive mathematical formula. Krawczyc went farther proposing Spirolaterals based in curved lines. He pointed out that there are a variety of spirolateral forms that have architectural potentiality. Following this, the architectural potentiality of Spirolaterals is the basis of this paper.

To take advantage of that potentiality a computer program was implemented to generate spatial configurations based in Spirolaterals. When a third dimension is given to the Spirolaterals they become Spirospaces. These new entities need spatial and design parameters to be useful for architectural purposes. Barrionuevo and Borsetti (2001) gave results about that work establishing the concept of Spirospaces.

The aim of this paper is to describe a work directed to improve rules and procedures concerning Spirospaces. It is expected that these procedures governed by the proposed rules can be employed as tools during the early steps in the architectural design process.

In this work some aspects concerning Spirospaces are considered. First, Spirolaterals are presented as the predecessors of Spirospaces. Second, Spirospaces are defined, together with their structural parameters. Architectural modeling is studied at the light of two special elements of the Spirospaces: Interstitial spaces and Object spaces. Next, a computer program is presented as the appropriate tool to model configurations having architectural potentiality. Finally, the results obtained running the computer program are analyzed to determine their possible use as architectural forms. Several graphic illustrations are presented showing steps going from the exploration of spatial alternatives to the selection of a specific configuration to be developed.

It is expected that the described computer program could be employed as a design aid tool. As the operation of the program generates a variety of spaces able to dwell architectural objects, it eases the search of configurations suitable to specific functions. The results obtained have the possibility of being exported to computer graphic applications able to add materials, lights and cameras.

summary The professional perception of the architectural space characterizes the most advanced level of the architect’s mastership. In the article the virtual modeling is regarded as an effective way of forming the professional perception of integrity of architectural space. Computer technologies bring together bi-dimensional and three-dimensional languages of modeling and thus they help the procedure of movement of consciousness from the plane to volumetric images and back to the visual and mobile. They help to carry out the level-by-level analysis of the multilevel structure of an architectural reality in the mode of active dialogue. The process of interaction of consciousness with the model becomes accessible to studying. There appears an opportunity to manage this process with the aim of forming perception.

summary This research was focused on visualizing new housing model and its customization based on people’s option as part of implementing community-based development principle. There are two significant research findings that are discussed in this paper that will be basis for developing a user-friendlier digital model as part of longterm research in visualizing whole resettlement process. The role of local person who is authorized to handle the model and to customize it to other inhabitants in the resettlement area is very essential in order to achieve the maximum versatility of the model. Another significant finding is potential of VRML model as information nodes for other digital modeling alternatives in an integrated information system for urban revitalization project.

summary This paper presents a study in digital design and manufacturing of shells, which are material-efficient systems that generate their load-bearing capacity through curvature. Their complex shapes are chal­lenging to build, and the few current shell projects employ the same shape repetitively in order to reduce the cost of concrete formwork. Can digital design and manufacturing technology make these systems suitable for the needs of the 21st century? The research developed new digitally-driven fabrication processes for Wood-Foam Sandwich Shells and Ferrocement-Concrete Sandwich Shells. These are partially pre-fabricated in order to allow for the application of Computer-Numerically Controlled (CNC) technology. Sandwich systems offer advantages for the digitally-enabled construction of shells, while at the same time improving their structural and thermal performance. The research defines design and manufacturing processes that reduce the need for repetition in order to save costs. Wood-Foam Sandwich shells are made by laminating wood-strips over a CNC-milled foam mold that eventually becomes the structural sandwich core. For Ferrocement-Concrete sandwich shells, a two-stage process is presented: pre-fabricated ferrocement panels become the permanent formwork for a cast-in-place concrete shell. The design and engineering process is facilitated through the use of parametric solid modeling envi­ronments. Modeling macros and integrated Finite-Element Analysis tools streamline the design process. Accuracy in fabrication is maintained by using CNC techniques for the majority of the shaping processes. The digital design and manufacturing parameters for each process are verified through design and fabrication studies that include prototypes, mockups and physical scale models.

summary The direct and rapid connections between scripting, modeling and prototyping allow for investigations of computation in fabrication. The manipulation of planar materials with two-dimensional CNC cuts can easily create complex and varied forms, volumes, and surfaces. However, the bulk of research on folding using CNC fabrication tools is focused upon surfaces, self-supporting walls and shell structures, which do not integrate well into more conventional building construction models.This paper attempts to explain the potential for using folding methodologies to develop structural members through a design-build process. Conventional building practice consists of the assembly of off-the-shelf parts. Many times, the plinth, skeleton, and skin are independently designed and fabricated, integrating multiple industries. Using this method of construction as an operative status quo, this investigation focused on a single structural component: the truss. A truss is defined as: “A triangulated arrangement of structural members that reduces nonaxial external forces to a set of axial forces in its members.” (Allen and Iano 2004)Using folding methodologies and sheet steel to create a truss, this design investigation employed a recyclable and prolific building material to redefine the fabrication of a conventional structural member. The potential for using digital design and two-dimensional CNC fabrication tools in the design of a foldable truss from sheet steel is viable in the creation of a flat-packed, minimal waste structural member that can adapt to a variety of aesthetic and structural conditions. Applying new methods to a component of the conventional ‘kit of parts’ allowed for a novel investigation that recombines zero waste goals, flat-packing potential, structural expression and computational processes.

summary Along with the development of computer technologies and CAD/CAM, digital tools are increasingly adapted in architectural design. Developed thus far, functions of digital tools are no long limited to two-dimensional drafting or final presentation; they have become tools that can assist design thinking. Because of the involvement of digital tools, the design process has been greatly affected; or, one may say that digital tools liberated the confines of forms and structuring of architectures. This research aims to explore the procedures in the design process using digital tools. In the conclusion, we found that in an attempt to abridge the gap between design ideas and actual implementation, the designer used the digital reality simulation function very frequently to assist in decision making, and in order to process more complex and freer forms, the designer relied on the 3D design environment to carry out his thinking process and amendments. In addition, the digital design process is mainly conducted through the methods of 1, 3D modeling, 2, Simulation, 3, Generation, and 4, Fabrication. The steps and methods in the digital design process are obviously different from the traditional ones, which focus mainly on mass-production of 2D drawings; therefore, it is certain that the new tools will change the outcome of the designs.

title Testing the relevance of parameterization to architectural epistemology
source Architectural Science Review, Volume 52.2: 135-141
summary Advances in building information modeling (BIM) deeply impact the production of new architecture; its benefits are obvious and its acceptance widespread. But how does BIM impact the study of existing architecture? Can BIM be assumed to operate as a neutral framework, equally applicable to the study of architecture anywhere? Using as a point of departure a recent outline of the conceptual structure of parametric modeling prepared by Sacks, Eastman, and Lee (2004), this paper compares parametric models of two existing works of architecture: Mies van der Rohe’s Crown Hall and Peter Zumthor’s St. Benedict Chapel. The processes of parametrically modeling each building are specifically compared in two ways: first, parameters are established for each model; second, each model is "flexed" as a means of disclosing possible semantic relationships within each work of architecture. Because each building demands a different parameter-establishment strategy, and because the models permit different degrees of flexibility, the comparison illustrates the shortcomings of a "neutral framework" assumption to an architectural epistemology.

summary Three conditions exist that are likely to lead to significant restructuringof the construction industry. These are (1): the recognition that traditional contracting practices are inefficient and costly to the client, (2) the growing availability of information-rich 3D parametric modeling, and (3) the strong interest in integrating the issues of design and fabrication. Some aspects of these conditions are examined using two examples: parametric design and integration in steel structural design, and in fabrication-level modeling of precast concrete. The implications of these changes are explored.

summary Keyframing, Morphing, Inverse Kinematics; they are all animation technics which have been explored by diverse groups of architects, academics and students, searching for new horizons in the proyecting process development, pushing forward the present limits of proyecting methodology. We define this project starting by the explorative use of animation tools as experimental variables in reformulating our design processes. Data input have been traditionally carried out using classic interfaces such as keyboard, mouse, graphics tablet, among others. Despite this is accepted by many as the standard way of communicating with machines, we think this is still very far from the ideal way to design and model new proposals. In this context we propose to investigate a new way to approach to the computed aided modelling process, questioning and reformulating traditional interfaces in user .machine communication.

summary The introduction of VRML (Virtual Reality Markup Language) in 1994, and other similar web-enabled dynamic modeling software (such as SGI’s Open Inventor and WebSpace), have created a rush to develop on-line 3D virtual environments, with purposes ranging from art, to entertainment, to shopping, to culture and education. Some developers took their cues from the science fiction literature of Gibson (1984), Stephenson (1992), and others. Many were web-extensions to single-player video games. But most were created as a direct extension to our new-found ability to digitally model 3D spaces and to endow them with interactive control and pseudo-inhabitation. Surprisingly, this technologically-driven stampede paid little attention to the core principles of place-making and presence, derived from architecture and cognitive science, respectively: two principles that could and should inform the essence of the virtual place experience and help steer its development. Why are the principles of place-making and presence important for the development of virtual environments? Why not simply be content with our ability to create realistically-looking 3D worlds that we can visit remotely? What could we possibly learn about making these worlds better, had we understood the essence of place and presence? To answer these questions we cannot look at place-making (both physical and virtual) from a 3D space-making point of view alone, because places are not an end unto themselves. Rather, places must be considered a locus of contextualization and embodiment that ground human activities and give them meaning. In doing so, places acquire a meaning of their own, which facilitates, improves, and enriches many aspects of our lives. They provide us with a means to interpret the activities of others and to direct our own actions. Such meaning is comprised of the social and cultural conceptions and behaviors imprinted on the environment by the presence and activities of its inhabitants, who in turn, ‘read’ by them through their own corporeal embodiment of the same environment. This transactional relationship between the physical aspects of an environment, its social/cultural context, and our own embodiment of it, combine to create what is known as a sense of place: the psychological, physical, social, and cultural framework that helps us interpret the world around us, and directs our own behavior in it. In turn, it is our own (as well as others’) presence in that environment that gives it meaning, and shapes its social/cultural character. By understanding the essence of place-ness in general, and in cyberspace in particular, we can create virtual places that can better support Internet-based activities, and make them equal to, in some cases even better than their physical counterparts. One of the activities that stands to benefit most from understanding the concept of cyber-places is learning—an interpersonal activity that requires the co-presence of others (a teacher and/or fellow learners), who can point out the difference between what matters and what does not, and produce an emotional involvement that helps students learn. Thus, while many administrators and educators rush to develop webbased remote learning sites, to leverage the economic advantages of one-tomany learning modalities, these sites deprive learners of the contextualization and embodiment inherent in brick-and-mortar learning institutions, and which are needed to support the activity of learning. Can these qualities be achieved in virtual learning environments? If so, how? These are some of the questions this talk will try to answer by presenting a virtual place-making methodology and its experimental implementation, intended to create a sense of place through contextualization and embodiment in virtual learning environments.

summary This paper is original research that demonstrates new design possibilities for evaluation in the schematic phase of design through the use rapid prototyping as a tool of representation verses 2D drawing. These program shapes are created from CAD files using a threedimensional printing and laser cutting CAM tools. This way of working is in response to two dimensional plan representation and evaluation (Mitchell 1976). This research combines the best of the visual aspects of plan representation and the formal representation of solid block modeling. The models in this paper demonstrate the building’s physical scale of spaces, building use and overall form. Resulting models will demonstrate a new way of designing in CAD one that combined physical and visual ways or representation.

title Finding of Form
source ETH postgraduate studies final thesis, Zurich
summary The intention of the thesis is to explore the spatial effect created when multiple forces interact in the formation of space. Instead of modeling the form, an internal generative logic is articulated which then produces a range of possibilities for the “fi nding of form”. As a first step creative relationships are being built between the objects in the space and different behaviors are assigned to them. This way, objects interact with each other rather than just occupying space. New fields of infl uence are added or new relations made, creating new variations. These interdependencies then become the structuring, organizing principle for the generation and transformation of form. The surface boundary of the whole deforms as fi elds of infl uence vary in their location and intensity. The insertion of the dimension of time gives the opportunity to follow and observe the deformation process and establishes a relation of continuity between the objects and the space.

doi https://doi.org/10.52842/conf.caadria.2004.613
summary The current means of transferring architectural data to the construction site depends mainly on the drawing either manually or electronically drafted both in physical or digital formats. The printed or manually drafted drawing is being replaced with the digital version that can be accessed with a PDA. There are many benefits of the digital form over the physical form. However the full potential of this medium has not yet been fully exploited. The new CAD paradigm, BIM (Building Information Modeling), suggests that all the building information can be represented as a digital database that constitutes the information about the building elements as three-dimensional geometry, as well as, properties and specifications in the form of objects. This paper describes the process to convey the information about the CAD objects to the construction site through the web by extracting the properties of the objects into an XML file which can be queried for the needed data.

summary This contribution is devoted to the brief description of the basic directions and tendencies of researches of the laboratory of video systems MARCHI. In connection with development of hardware-software computer means and their practically absolute, not alternative application in the practice of architectural designing, nowadays (not always is proved) the sphere of application of the former traditional methods of physical modeling and their connection to the endoscopic methods has been narrowed. We consider some new probable directions of development of scientific and educational work within the framework of activity of our laboratory, allowing a more balanced approach to these problems. As we have discussed, our theoretical researches and practical works must reassume an existing non-standard and controversial situation in Russia, such as established substantial intellectual potentials in scientific- and methodological researches within study processes. In addition to that, what we can use are affordable and limited physical and financial recourses and capability for technical development of works for modeling perception in designing architectural and town planning space. These initiated searches in the field of non-standard thinking, derive from our contacts with EAEA colleagues. Below we will try briefly to explain our basic principles of work development. (To be clear, some time we dismiss references and notes into exact reports from our conferences supposing that interested colleagues may get further and detailed information from already published past events).

summary By incorporating parametric surfaces and spline entities into the shape modeling computer systems, new design and production graphic tools have been created in the conceptual and poetic field of architecture; thus allowing an intuitive approach to the fast production of complex shapes with a minimum amount of data and specific knowledge. The analogous production systems (constrained by the material resources and constructive procedures present in the local existing technologies) are challenged by design and virtual simulation systems, suggesting new relationships between the architectural features and their representation: the creation of a symbolic and dynamic information space where the representation affects the identity of what is being represented. Taking into account this current challenge mentioned above, we have decided to work in the mixture, without reciprocal exclusions or substitutions, proposing some work alternatives to approach the issue under discussion in the Architecture Workshop.

summary This paper presents an updated evaluation of an experience of applying computer graphics, virtual reality and Internet resources in the teaching of technical graphics at the University of Brasilia, Brazil. It differs from a previous paper (Pratini, 2004) for the addition of an overview of the course, the context and the new teaching methodology. It is an extended, more detailed paper, which includes examples, and closes with some results of surveys on the didactic material and the methodology. Our motivation for this experiment is the fact that most of the students have a lack of previous knowledge on the basis of drawings, resulting difficulties in both understanding and visualizing technical drawings. In this experiment, we introduced VRML 3D modeling in addition to CAD and regular pencil-and-paper drawings study and practice. To support the learning of this broad knowledge not present in the technical graphics bibliography, we first provided a website with animations and virtual reality resources. Since 2003 we are providing a CD-ROM containing all the former website material which is updated each semester. At the present time, the CD-ROM contains almost all the needed didactic material and software for the one semester technical graphics course. This experience was intended to improve and to support learning in a way that motivates the students, young people who are used to play video and computer games. Classes, website and CD-ROM material were conceived to take advantage of computers´ interactivity and animated resources. The use of computers´ technology and new media to support the learning resulted a new methodology and several new unanswered questions.

title Modeling with Gestures: Sketching 3D Virtual Surfaces and Objects Using Hands Formation and Movements
source eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary The 3D SketchMaker project has developed two prototypes for a gestural 3D sketching system to be used in the earliest phases of the design process. The goal of this ongoing research is to provide architects, and other designers involved in object conception, with a 3D gestural instrument that takes advantage of new virtual reality resources and is more natural than using the mouse, less difficult than learning complex software and less abstract than manipulating 2D entities on orthogonal projections. The system was conceived to assist or replace the first 2D drawing steps in the design process, generating rough 3D sketches that can be refined later using any 3D package. It is, in essence, a 3D modelling system directed to do sketching with hand movements and gestures in a virtual reality environment.

title Divergent Thinking in the Construction of Architectural Models
source International Journal of Architectural Computing vol. 2 - no. 2
summary The article examines one little understood butubiquitous form of divergent thinking achievedintermittently during the act of drawing or modeling.It is argued that this phenomenon, here calledintermittent divergence, is rooted in a special kind ofinteraction between perception and imagination, andthat this interaction has specific experientialrequirements. Three requirements are defined. Theresulting new theory then provides a framework forthe critical analysis of conventional digital modelingand parametric modeling. Conventional modelingmethods are shown to satisfy the requirements forintermittent divergence, while parametric modelingmethods are shown to undermine them. The articleconcludes that parametric systems, as currentlydeveloped, could inhibit rather than augment thisimportant route to creativity. Additionally, the articlequestions prevailing beliefs about the computersupport of creativity, including the premise thatsketching is an ideal creative medium and the premisethat ambiguity in graphical depictions is key to thesupport of creativity. The theory offers an alternativeview on these issues.
