title Infilling Time into Space - A Pedagogical Approach for Evolving Space Using Digital Media
source Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 147-154
summary This paper presents a pedagogical approach to explore the relationships between time and space by using digital media. Based on a pedagogical model called e-Space proposed by Lai (2004), we apply motion as a spatial issue to approach this study. Through integrating with the characteristics of digital media, students are encouraged to evolve architectural space and form by decomposing, re-organizing, interpreting and realizing the spatial composition. Simultaneously, diverse digital media applications integrated with design thinking in a design process enables students to bridge two design spaces - physical and virtual. This process introduces the students to a new approach of design-creation and form finding. Finally, we use an advanced digital media course as an example to understand the impacts of the pedagogical approach. The students’ outcomes are also reported in this paper

title Comprehend the Term ‘Info-City’ - A Comparison between Two Primary Cities in Taiwan
source Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 508-514
summary The rising of Information Communication Technology influences cities globally. ‘Info-city’ is the very topic to be reconsidered if each city acts as a combination of the physical and virtual. This research is an attempt to understand and formalize the comprehension of Taiwan people about ‘Info-city’. For the sake of reliability, there are 37 interviewees from Taiwan’s enterprises providing experiences of daily urban lives as a field to explore. In order to organize oral corpus, the research method applies encoding in term of cognitive semantics. Every sentence in the database is regarded as a basic unit to analyze. Besides that, there’s a framework consisted of two analytical dimensions to reveal a clear picture of the collective minds. The results are concluded that concepts of ‘info-city’ in Taiwan value the mechanism of synergy most instead of the effect of substitution as an arbitrary assumption among urban studies.

source Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 74-81
summary In this paper we describe the impact of 3D video technology on immersive telepresence applications in the context of architecture. This technology enables new ways of collaborating and communicating between distant locations. The photorealistic appearance of a 3D user representation and other objects allows for natural and close co-operation in immersive spaces. We conclude with experiences and results derived from inserting and interacting with 3D representations of users in specific Virtual Reality scenarios.

title Interactive Spaces for Advanced Communication using 3D Video
source International Journal of Architectural Computing vol. 2 - no. 1
summary Architects integrate more and more modern information technologies in their projects. Based on this background the use of 3D video in an architectural context is discussed. The combination of real-time 3D video and blue-c technology for a distributed shopping experience in shared virtual shops is described. IN: SHOP illustrates an approach to enhance physical environments in shopping areas and connects geographically distant persons. These technologies offer new architectural design possibilities. The traditional understanding of location, space, and time may be redefined. Interactive spaces are being designed, modified and experienced. We believe that information technologies have an impact on buildings and architecture.

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.

source SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary With the continuous advancement of scientific knowledge more attention has been paid to the accuracy and consistency of graphic representation in Science Education. In addition, the dissemination of web based distance education has increased the development of new educational material and tools; nevertheless many of them have poor efficacy due to the lack of a design that integrates the interdisciplinary needs of the educational project into product planning and development. This paper presents the results of the design of a constructivist computer based learning environment (WEB based or CD-ROM) aimed at the teaching and learning of Classic Genetics. The analyses of results revealed that the prototype design was approved by specialists in the fields of Genetics, Educational Technology, and Informatics; it was also perceived as a powerful learning tool by students.

summary Having as topic for the conference the tile with keywords such as culture, technology, and architecture, we were expecting to find out the relationships among those three domains, and how they are interrelated in this fast growing information society. This triangular relationship has been established based on the increasingly noticeable paradigm shift from traditional computer-aided design research in architecture to research in diverse areas such as virtual environments and communities and interactive smart spaces, including the consideration of sociocultural aspects along with the technological issues. Making virtual environments focuses on creating a new, yet virtual world where people can inhabit or visit for diverse purposes. The virtual architecture becomes a medium for diverse communications as well as digital contents for the new media industry. For example, virtual heritage projects introduce a new way of preserving historic buildings and sites. At the same time, interactive smart spaces often combine two different worlds: real and virtual worlds. Growing digital technologies enables us to create intelligent physical spaces where computers are ubiquitous and invisible in space, and thus human beings can interact with architectural spaces, not necessarily with computers directly. At this point, issues on virtual reality (VR) and human computer interactions (HCI) become architects' and designers' concerns in socio-cultural aspects. The proceedings of the Nineth International Conference on Computer-Aided Architectural Design Research in Asia, presents 74 papers which were selected from the 131 submissions through a blind review of 58 international reviewers. Each submission was reviewed by three reviewers and the final acceptance was based on their recommendations.

summary Color selection plays a vitally important role in creating impressions of individuals or companies because colors have sensibility aspects and relate to some images or associations. Based on both the theory of color harmony and the sensibility ergonomics, some quantitative and systematic researches on the color image have been developed. In this paper, we suggest a color coordinate system that supports the color analysis and the color harmony functions using color images, which can be captured by corresponding adjective words. We focus on a system prototype for interior design domain to exemplify our concepts in this paper, even though this system can be applied for all design domains.

title Towards Computer Aided Life-Cycle Costing
source eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary Sustainability is recognised as a necessary public good. Building sustainable buildings requires architectural methods, specifically CAD systems, that include suitable predictions of long term performance. Unfortunately the predominant view in the Building Industries of the Developed world is essentially short term; this is because building developers – not being the end users - are essentially interested in short term profit. Until they can see the ‘value-added’ by sustainability impacting on the selling price of their buildings, they will not be motivated to build ‘sustainably’. This paper describes the issues that have led to this situation. It discussed how the advent of computers has allowed life-cycle data to be gathered over time, and may be included intro CAD system databases to enable sustainability performance predictions to be made. Once made we are now able to reap the benefits by performance benchmarking. The availability of this building performance information on-line is making life-cycle costing more readily available, and more accurate, allowing building developers, owners and users to make rapid and timely feasibility studies well in advance of design. This also allows owners to test various capital to operating cost options in order to get the best economic performance over time, as well as map future capital replacement cycles. These emerging possibilities are discussed in this paper.

summary At the last conference we emphasized, that the presentation had to transport the whole project. This time we will present adequate methods of computer aided spatial simulation in education and practice that promote spatial imagination in the design process and the suggestive power of a presentation, while we still bear in mind the unity and the reciprocal influence of the design process and the presentation, that is spatial imagination and spatial simulation. Working on the computer first of all means to choose the appropriate software tool to exploit different aspects of specialized software from mathematical constructions to emotional experiences and from interaction to immersion.

summary Computer visualizations of planned built environment and infrastructures are increasingly used as a basis for democratic decisions when the impact of the projects is of wide-ranging interests and influence. It is of great importance for the democratic process that all aspects of the material in a project can be trusted as a basis for discussion and decisions among politicians and citizens. This paper describes the objective aspects of the quality of data in the information basis for 3D visualizations and it calculates the precision that can be achieved by the known methods of 3D-CAD visualization. Furthermore, the paper suggests a model that can secure sufficient quality in future visualization work processes by accumulating documentation for both the factual basic data and information that carry the aim and meaning of the message and make this information accessible through the visualization.

summary This paper describes experimental work carried out in a special architectural design studio. It runs methods that are different of the traditional teaching in the .normal. studios. The entire working time is separated in two characteristic periods: .Creative tasks. and .Design tasks.. The purpose is to clarify the design process assuming that generating ideas has quite different characteristics than leading them to the real world. Creative work means imagination whose limits are difficult to establish. In fact imagination hates imposed limits. Conversely the final task of design is to determine limits. These two opposed forces are conciliated in the design process. Ideas as well as physical objects need special means of representation. These are discussed in order to illustrate the trends underlying this particular design studio. (Architecture, design, teaching, digital representation)

title A Parametric Approach to the Design of Vaulted Tensegrity Networks
source International Journal of Architectural Computing vol. 2 - no. 2
summary Significant new research in tensegrity theory and technology encourages tensegrity’s implementation in architecture. A recently developed technology makes possible the rapid modular assembly of deployable tensegrity units, and the construction of alternate curved configurations by re-using the same modules. Although a form exploration method for tensegrity structures already exists, estimating the structure’s new geometry remains a challenge due to difficulties designers encounter in understanding and following the method’s geometric construction process. Besides, the method doesn’t address the geometry of vaulted configurations. This paper presents algorithms that link together the geometric parameters that determine the shape of tensegrity vaults by addressing different design-construction scenarios, and a software code that generates parametric models of tensegrity vaulted structures.The application of the algorithms to the morphological study of a tensegrity vaulted dome, which constituted the main feature of an entry to arecent international architectural competition, is also presented.

title A computer Based System for the Design and Fabrication of Tensegrity Structures
source Fabrication: Examining the Digital Practice of Architecture [Proceedings of the 23rd Annual Conference of the Association for Computer Aided Design in Architecture and the 2004 Conference of the AIA Technology in Architectural Practice Knowledge Community / ISBN 0-9696665-2-7] Cambridge (Ontario) 8-14 November, 2004, 100-109
summary Tensegrity structures are composed of tension compression com­ponents, where the compression components (bars) are discontinu­ously enclosed within continuous tensile components (cables). From an engineering point of view, a tensegrity structure is characterized by geometric non-linearity and large displacements under loading. Therefore, its prestressed shape and deformation under loading are the result of the combined effect of the geometric parameters that determine the initial configuration of the structure, the level of pre­stress applied to cables, and the material properties of the compo­nent members of the structure. A method for generating the initial geometric configuration of tensegrity structures composed of tenseg­rity units and a parametric expression of this geometry have already been developed. A novel technology that makes possible the construction of tensegrity structures from the on-site assembly of deployable tensegrity units, which are fur­nished with a simple mechanism that permits bar-elongation, and, as a result, an increase of the prestress applied to the cables of each unit, is also under development. Also under development is a static analysis method that takes into account the above method for prestressing cables. This paper discusses the features of a system that supports the combined geometric and structural design of tensegrity structures, and integrates a graphical interface to display: a) models of initial geometry, b) geometry of the structure after prestress and loading are applied, and c) magnitude of forces applied to the structure’s component members (bars and cables). The system also provides numerical data to be used in component fabrication, and is therefore expected to become a very valuable tool for the design and construction of tensegrity structures.

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

summary Addressing the issue of building re-use, this paper reports on the development of a re-design tool, which aims at helping students and novices (and even experienced architects) in understanding design decisions that have steered existing re-design projects. Furthermore the tool tries to support designers in using this understanding in their own design projects. The paper starts by situating the re-design tool within the overall research setup, and continues by motivating the observations that have led to developing this tool. The core of the paper describes the re-design tool itself and illustrates it with a concrete example. Finally, the tool is framed within the wider context of (architectural) design research, so as to explore where the tool accords or collides with generally accepted design theories.

summary Observation of the design process of an architect shows that, while building up an argumentation for taking a design decision, different mechanisms of data transformation are used. The paper argues that this transformation is a key element in understanding architectural design processes. A theoretical description of these mechanisms forms the framework to discus a sequence of design decisions derived from a real-world design situation. After outlining how this can be implemented in a case-based design supporting tool, the paper concludes with a discussion of advantages and downsides the use of the tool might entail.

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.

summary This project describes a way to combine real-world images with graphical representations of three-dimensional objects.In architecture the combination of physical and virtual spaces is a traditional approach to propose the design of a building. Presenting a virtual design as it appears in relity requires either an unsatisfying level of abstraction while being on-site, as with sketches, or the performing of several ardous tasks. While in this case the quality is appropiate, it is now unlikely to get immediate results.Combining an interactive modeler as the primary designing instrument with a augmented reality system as mixture of cameras, GPS-devices and fiduciary features the system can demonstrate how augmentation as tool in architecture might work.

summary 3-D printers alter the speed, cost, complexity, and consistency with which physical architecture models can be crafted. If architects are to harness the unique abilities of this modeling process, it is necessary to find a complementary means of conceptualizing designs and generating the geometric data necessary for 3-D printing. This paper introduces a novel combination of 3-D printing and scripting through three examples of architectural surface models. In these examples, VBScript is used to write generative scripts for execution within the Rhinoceros modeling environment. The scripts produce digital geometric models which, in turn, are exported to a Z-Corp 3-D printer. The merits of this methodology are demonstrated, in one example, through models of an architectural surface composed of light-modulating conical components. The design intent in this example is a grid of responsive components which ride on a complex curved surface and steer toward a light. The written script is an explicit representation of this intention. Methods in the script use external parameters to generate a digital geometric model. The form of the subsequent printed model is calculated as a function of the initial parameters, two boundary splines and a vector indicating the orientation of the light. By varying these parameters, a set of design options can be generated and 3-D printed for comparison. The combination of scripting and 3-D printing allows complex design intentions to be managed in a concise, sharable format and modeled iteratively without manual intervention.
