title	Técnicas Cinematográficas para las Animaciones Arquitectónicas (Film-making techniques for Architectural Animations)
source	SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary	The paper presents film techniques for the expressive development of architectural animations, based on a graphic analysis of productions related to architecture (famous movies, documentaries of buildings and contemporary animations). This study is revealing some cinematographic concepts such as the dynamic composition of image, diversity of camera's positions, control of movements and rhythmic montage of shots that support a meaningful presentation of buildings. Also it suggests the geometric programming of movements and influences in the architectural design.

summary	This paper explains the experience performed by a group of architecture students during a short term worksop, trying to explore the potentials of new approaches and digital technics applied to urban and architectural design. The main purposes were: the inclusion of objetive information and quantitative data of material significance in order to assist the generation and structuring of the design process. The notions of "diagram", "field conditions", "contextual logistic" and "animation" were the conceptual categories employed to approach the dinamic conditions and time related logics as critical aspects of the flexibility associated with material organizations.

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

source	SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary	Hearing and touch may be incorporated into visual representation systems that historically covered creative process, now helped by multimedia. During 2002-2003 we developed an experimental design studio that challenged participants to design architecture from words (using their spelling, pronunciation, location, etc.) and through an inquiry based on the "concept of inwardness". Evoking a word from the association of images and texts as well as seizing its potential tactile and hearing dimensions completed what was a very interactive design process. Such process was utilized to generate images and ideas geared to design/make an "installation" to be displayed at art events.

summary	In order to design architecture projects, 1st grade architecture students have to understand the space and how to figure it out. To be succeeded in the design process it is necessary to develop their spatial abstraction capability. Each architectural representation tool can contribute for this development. This work shows the pedagogical experience applied to students of the first grade of architecture course at UNICENP, in Curitiba, Brazil, approaching the strategies of different subjects to increase the development of spatial skills using different architecture design tools.

summary	We present as an example a story entitled "Invisible Cities" by Italo Calvino in which the author describes an imaginary city. Appealing to mathematical concepts, students seek to design a type of city or architectural space, arising from each student's interpretation of the text. Here, Literature, Design and Mathematics form a framework in which each discipline justifies the presence of the others. In our private case the need of an evolution of the language is presented besides by means of the use of the Digital Graphic.

title	Needs Requirements Performances Vs Goals Constraints Values in Collaborative Architectural Design
source	SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary	The following is a report on an on-going research study aimed at defining a support system for Collaborative Design in architecture. This paper concisely shows the latest results. In the present report the emphasis is laid on the relations among the operators and their different goals. We studied the preliminary phase of the architectural design, for which we defined a model and implemented a software system. The validity of the software system does not decrease when it is extended to the remaining design phases. The goal of the research is to improve collaboration among operators.

title	An empirical approach to the experience of architectural space in VR - Exploring relations between features and affective appraisals of rectangular interiors
doi	https://doi.org/10.52842/conf.ecaade.2003.017
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 17-24
summary	While it is well known that the built environment influences our emotional state, it is often difficult to attribute these experiences to particular properties. In fact, a systematic investigation of the relation between physical structure and emotional experience of architecture has not yet been done. Now virtual reality simulations facilitate a completely controlled variation of spatial properties and thus allow to empirically evaluate architectural hypothesises. The aim of the presented study was to investigate which factors from a component-based description of rooms significantly correlate with cardinal dimensions of experience. In a perceptual experiment experiental qualities of 16 virtual vacant rectangular interiors were rated in eight principal categories by 16 participants using the semantic differential scaling technique. The scenes were generated by a custom made graphics tool that also automatically generated the component-based scene descriptions. The data analysis revealed several interesting correlations between scene features and rated experience: For example, a preference for ratios near to the golden section could be observed for spatial proportions, which are not directly perceivable. Altogether, a set of five independent factors (openness, two room proportions, room area and balustradeheight) appeared to be effective for widely describing the observed variance of the averaged attributed experiental qualities. Our combination of realistic virtual reality simulations and psychophysical data raising methods proved to be effective for basic architectural research. It allowed us to demonstrate quantitative relations between physical properties from a component-based description of architectural space and its emotional experience.

title	Enhancing Architectural Communication with Gaming Engines
doi	https://doi.org/10.52842/conf.acadia.2003.349
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 349-355
summary	This paper makes a case for exploring the feasibility of utilizing the advanced graphics and sound systems of contemporary gaming engines to promote architecturally relevant work. Gaming engines, while developed largely for the PC entertainment industry, have vast potential for application in architecture. This paper will explore the depth of this potential and will outline work demonstrating the advantages and the limitations of this technology. The supporting research and observations examine the technology and reveal its potential usefulness as an instructional or depictive authoring tool. Game engines were selected that had appropriate graphical prowess, but were customizable as to allow the removal of game-specific features (to create a “professional” user interface). Projects were authored that expressed complex building details using the engine for visual depiction. The details, which included constructional components, structural assemblies, or simple design nuances, were modeled with 3D geometry and realistically textured and lighted. The game engine allowed one user or many remote simultaneous users in the virtual environment to interactively explore the presentation in real time. Scripts were developed to encourage end-users to interactively disassemble or reassemble building components as desired. Audile and/or text-based information regarding the assembly sequence were provided by exploiting the game interface features. Furthermore, interactive object scaling was provided to facilitate analysis of component relationships.

title	The Level of Knowledge of CAD Objects within the Building Information Model
doi	https://doi.org/10.52842/conf.acadia.2003.173
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 173-177
summary	The first generation of CAD software depended on entity objects that were manipulated and interpreted by the user as meaningful graphics symbols. These entities only represented the geometrical properties of the architectural elements. With the present emerging generation of CAD systems, a new concept shifts a drawing-based model into a Building Information Model with the potential of modeling true architectural objects. Theoretically, these CAD objects will provide all related data to the designer describing the geometry, as well as any related data associated with how the object is actually used. The knowledge required to support an object should have structure to it. Different levels of knowledge need to be included, such as the geometrical information, which should be flexible enough to accommodate any type of shape and modification while keeping the object’s integrity as a unit and maintaining its relations to other objects. The CAD object concept, as remarkable as it is, might also have potential problems. It has some implications over the design process, as well as the architectural profession itself.

title	Architecture and the Stereoscopic Space of Experience
source	SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary	The conceptualization of architectural space is undergoing radical innovation. Architect-designers have become perceptual painters of animate experience through the use of digital stereoscopic technologies that permit the sensorial intensity of an experience of movement, color, form, and space. It is in creating such direct experiences for a client-user that this becomes defined as a necessary phase prior to the abstractive and pragmatic phases of design. This creates a new originating context -- a new paradigm -- to which a client-user will refer, thus creating an alternate model for design programming.

summary	This paper presents the development of a prototype XMLbased 3D campus map using the 3D VML library. Many universities in the U.S. use two-dimensional (2D) raster image to provide the campus map along with additional building information on their Web site. Research shows that three-dimensional (3D) expression of the 3D objects helps human beings understand the spatial relationship between the objects. Some universities use 3D campus maps to help visitors more intuitively access the building information. However, these 3D campus maps are usually created using raster images. The users cannot change the view point in the 3D campus map for better understanding of the arrangement of the campus. If the users can navigate around in the 3D campus map, they may be able to locate the building of their interest more intuitively. This paper introduces emerging Web technologies that deliver 3D vector graphics on the Web browser over the internet, and the algorithm of the prototype XML-based 3D campus map. Some advantages of using VML in delivering the interactive 3D campus map are also discussed.

title	Prêt-à-Construire – An Educational Inquiry into Computer Aided Fabrication
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 162-165
summary	This paper aims to show and discuss the relevance of developing necessary strategies for reintegrating the concept of fabrication into the architectural design process. The discussion will be partly based on the outcome of a graduate architectural design studio conducted in Spring semester 2002-2003. The graduate studio was part of a series of exploratory studies conducted on the nature of architectural design process transformed by information technologies. Preceded by studios investigating cognition and representation, this last studio focused on the concept of fabrication. The overarching aim of the studio series was to put CAD and CAM in context both within the actual architectural design process and within architectural education. The last of this series, which will be discussed within the frame of this paper, has specifically focused on CAM and the concept of fabrication in architecture. In accordance with the nature of a design studio, the research was more methodological than technical. The studio derived its main inspiration from the constructional templates used in dressmaking, which can be considered as an initial model for mass customization. In this context, the recladding of Le Corbusier’s Maison Domino was given as the main design problem, along with several methodological constraints. The main constraint was to develop the design idea through constructional drawings instead of representational ones. The students were asked to develop their volumetric ideas through digital 3D CAD models while working out structural solutions on a physical 1/50 model of Maison Domino. There was also a material constraint for the model, where only specified types of non-structural paper could be used. At this stage, origami provided the working model for adding structural strength to sheet materials. The final outcome included the explanation of different surface generation strategies and preliminary design proposals for their subcomponents. The paper will discuss both the utilized methodology and the final outcome along the lines of the issues raised during the studio sessions, some of which could be decisive in the putting into context of CAD – CAM in architectural design process. One such issue is mass customization, that is, the mass production of different specific elements with the help of CAM technologies. Another issue is “open source” design, indicating the possibility of a do-it-yourself architecture, where architecture is coded as information, and its code can be subject to change by different designers. The final key issue is the direct utilization of constructional drawings in the preliminary design phase as opposed to representational ones, which aimed at reminding the designer the final phase of fabrication right from the beginning. Finally, the paper will also point at the problems faced during the conduct of the studio and discuss those in the context of promoting CAM for architectural design and production in countries where there is no actual utilization of these technologies for these purposes yet.

source	SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary	The foreshadowing and transfiguration of architectural space using digital technologies proposes a new order among the physical, symbolic and digital interrelations, where these entities coexist, not only as part of the process that orchestrates thought, but as important mechanisms within the creative process. So we accept that the potentiality of a computerized diagrammatic model expresses more that simply functional aspects, becoming the representation of thought, problems solving and communication, developing images that allow us to explore and to evaluate alternatives, bringing closer objects that we perceive by means of the senses, as well as those that we imagine or dream of.

summary	This work is developing at the moment, tries to find elements that allow arm to a frame of reference for a doctoral thesis that studies the processes of architectonic design and the transformations that this one within the factories of education with the introduction of the digital representation undergoes. It is a study that it initiates in the 2003 with an applied cuasi-experiment to students of the masters in architecture of the Independent University of Nuevo León (Monterrey, México), (work presented/displayed in the forum SIGraDi 2003). Taking into account the results obtained in that one first work it was decided not to take part and to force the student to work with a specific type of tool (digital or traditional), but to leave them chose the work tool freely, observing his photographic process by means of video-recordings, registries and personal interviews with the purpose of explaining because of his processes. The registries were taken in the Factory from semestral Architectonic Design 5°, of the Independent University of Aguascalientes (Mexico).

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.
