title Hyposurface: from Autoplastic to Alloplastic Space
source International Conference on Generative Art
summary By way of immediate qualification to an essay which attempts to orient current technical developments in relation to a series of dECOi projects, I would suggest that the greatest liberation offered by new technology in architecture is not its formal potential as much as the patterns of creativity and practice it engenders. For increasingly in the projects presented here dECOi operates as an extended network of technical expertise: Mark Burry and his research team at Deakin University in Australia as architects and parametric/ programmatic designers; Peter Wood in New Zealand as programmer; Alex Scott in London as mathematician; Chris Glasow in London as systems engineer; and the engineers (structural/services) of David Glover’s team at Ove Arup in London. This reflects how we’re working in a new technical environment - a new form of practice, in a sense - a loose and light network which deploys highly specialist technical skill to suit a particular project. By way of a second disclaimer, I would suggest that the rapid technological development we're witnessing, which we struggle to comprehend given the sheer pace of change that overwhelms us, is somehow of a different order than previous technological revolutions. For the shift from an industrial society to a society of mass communication, which is the essential transformation taking place in the present, seems to be a subliminal and almost inexpressive technological transition - is formless, in a sense - which begs the question of how it may be expressed in form. If one holds that architecture is somehow the crystallization of cultural change in concrete form, one suspects that in the present there is no simple physical equivalent for the burst of communication technologies that colour contemporary life. But I think that one might effectively raise a series of questions apropos technology by briefly looking at 3 or 4 of our current projects, and which suggest a range of possibilities fostered by new technology. By way of a third doubt, we might qualify in advance the apparent optimism of architects for CAD technology by thinking back to Thomas More and his island ‘Utopia’, which marks in some way the advent of Modern rationalism. This was, if not quite a technological utopia, certainly a metaphysical one, More’s vision typically deductive, prognostic, causal. But which by the time of Francis Bacon’s New Atlantis is a technological utopia availing itself of all the possibilities put at humanity’s disposal by the known machines of the time. There’s a sort of implicit sanction within these two accounts which lies in their nature as reality optimized by rational DESIGN as if the very ethos of design were sponsored by Modern rationalist thought and its utopian leanings. The faintly euphoric ‘technological’ discourse of architecture at present - a sort of Neue Bauhaus - then seems curiously misplaced historically given the 20th century’s general anti-, dis-, or counter-utopian discourse. But even this seems to have finally run its course, dissolving into the electronic heterotopia of the present with its diverse opportunities of irony and distortion (as it’s been said) as a liberating potential.1 This would seem to mark the dissolution of design ethos into non-causal process(ing), which begs the question of ‘design’ itself: who 'designs' anymore? Or rather, has 'design' not become uncoupled from its rational, deterministic, tradition? The utopianism that attatches to technological discourse in the present seems blind to the counter-finality of technology's own accomplishments - that transparency has, as it were, by its own more and more perfect fulfillment, failed by its own success. For what we seem to have inherited is not the warped utopia depicted in countless visions of a singular and tyrranical technology (such as that in Orwell's 1984), but a rich and diverse heterotopia which has opened the possibility of countless channels of local dialect competing directly with the channels of power. Undoubtedly such multiplicitous and global connectivity has sent creative thought in multiple directions…

title Multicast Shared Virtual Worlds Using VRML 97
source Proceedings of VRML 99 Fourth Symposium on the Virtual Reality Modeling language, The Association for Computing Machinery, Inc. New York, pp. 133-140
summary This paper describes a system for authoring and executing shared virtual worlds within existing VRML97 viewers such as Cosmo Player. As VRML97 does not contain any direct support for the construction of virtual worlds containing multiple users extensions are presented to provide support for shared behaviours, avatars and objects that can be manipulated and carried by participants in the world; these extensions are pre-processed into standard VRML97 and Java. A system infrastructure is described which allows worlds to be authored and executed within the context of the World Wide Web and the MBone.

title Some Phenomena of Touch in Study Models
source CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 1, pp. 277-287
summary The senses of “Touch” bring people the feeling of reality, and human beings can always naturally sense the tactile impression. Hence we touch things and our sense tells us that our hands are touching something (Hinckley et al. 1999). Comparing to the tools used by designers between traditional and new digital media in the design process, the most difference is in the sense of touch. This paper focuses on the sense of touch to point out the haptic experience which have ignored by the past in design process. Four phenomena will be discussed in details and some useful suggestions given for future study.

title Design Navigation and Construction Simulation by Virtual Reality
source CAADRIA '99 [Proceedings of The Fourth Conference on Computer Aided Architectural Design Research in Asia / ISBN 7-5439-1233-3] Shanghai (China) 5-7 May 1999, pp. 31-41
summary This paper depicts the approach of constructing a virtual reality environment for simulating architectural design and construction operations. The virtual environment is established to demonstrate the spatial performance of design and constructability of construction operations. Particularly, the functions such as navigation of construction sites, simulation of construction operations, and evaluation of construction details will be critical to construction operations. The system shell is implemented by JAVA on the web and integrated with VRML for supporting the above functions. The study focuses on the needs for the system integration and interface design. Four modes of human computer interfaces are proposed, including the user, agent, monitor, and immersion modes. Finally, this paper provides demonstration of construction simulation in an office building project to highlight the above discussion. The operations of crane towers and curtain wall installation are also studied in the construction process. In conclusion, this paper demonstrates the potential uses and limitation of virtual reality in simulation of the built environment.

summary Unique to the interior design program at Cornell University is a planned pedagogical approach requiring equal emphasis toward manual and digital graphic communication at the freshman level. Prior to 1998, computer-based instruction only occurred at the junior year of study. Recognizing that cultural and symbolic biases against digital media were formally being instituted by curriculum policy, faculty searched for a new perspective. Central to success was the removal of illogically placed boundaries, both mental and physical. In response, students are now encouraged to cultivate a fluid dexterity between traditional and digital methods, at times using various skills concurrently for design analysis and representation (Figures 1, 2, 3, 4, 5, 6, 7). Course content for DEA115 ranges from basic orthographic drafting, paraline projection, and perspective drawing to color rendering and composition. Students utilize a full range of media: pencil, ink, marker, pastel, AutoCAD, 3DS/ MAX, and Photoshop in this graphics studio. Course meetings total six contact hours per week, constituting a three credit hour class. Assignments are purposefully created to shatter digital myths. For example, instead of a standard, rote drafting exercise, AutoCAD is used to explore design ideas through systemic object manipulation (Figures 8, 9).

title CAD in Practice Profile: Polshek Partnership Architects LLP
source ACADIA Quarterly, vol. 18, no. 3, pp. 10-14
summary Since the advent of computers for architecture, James Stewart Polshek, FAIA, founding partner of Polshek Partnership Architects LLP, has insisted that his firm's technology standards match the same high level they maintain for their awardwinning designs. As explained by Senior Associate Don Weinreich, AIA, this objective translates into computing priorities that differ significantly from those of the average firm. Weinreich observes that many "typical" firms use computer technology for profitability first, consistency of documentation second, and enhancement of the design process last. At Polshek Partnership these priorities are reversed. Supporting and enriching the design process is the overriding objective of all computing activity at the firm. Consistency of documentation, as a second-level priority, is pursued not just for routine coordination and quality control, but in a proactive effort to maintain control over every detail in the process of communicating design intent—in other words, to further support design. The potential to increase profitability through computerization (e.g., by doing the same work in less time) ranks low among the computing priorities at Polshek Partnership. According to Weinreich, "the guiding principle is to do no harm," that is, to exploit the maximum potential of computers to support the design process without incurring additional net costs. In effect, the firm is taking the time and effort that computerization can save on many routine, procedural tasks and reinvesting those savings in additional design studies and details. This approach to computers for design is consistent with that of other AIA Firm Award-winning practices profiled in this series. (1)(2)

title Practical Support for Collaborative Design Involving Divided Interests
source Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 126-137
summary Collaboration is common in design, yet relatively little is known about the cognitive reasoning processes that occur during collaboration. This paper discusses collaborative design, emphasizing the elaboration and transformations of the problem search space, and the roles that unstructured verbal communication and graphic communication can play in these processes. The paper discusses a prototype system called the Immersive Discussion Tool (IDT) that supports asynchronous design. IDT allows collaborators to mark-up 3-D models over the Internet using a variety of tools, including diagrammatic marks, dynamic simulations and text annotations. IDT relies on VRML to view the models, with an extensive Java-based interface on the backend powering the interactive construction and playback of graphical annotations, the management of threaded discussions, and the management of file input/output. The development of this tool has revealed the difficulty of constructing complex marks in a virtual 3-D space, and the initial implementation of IDT suggests several strategies for solving these problems.

title Internet-based collaborative design evaluation : an architect's perspective
source Harvard University
summary This research aims at developing a design evaluation system that employs a Product Model as the logical basis for integrating building design and construction processes. The system is implemented with Java language, which allows the system to work over the Internet. Accordingly, the system helps architects to collaborate with remote participants. Thus, this design evaluation system is a building performance evaluator like DOE-2, RADIANCE, HVAC, and the Automated Building Code Checker. This research, however, is mainly concerned with an architect's view during the schematic design and design development stage, while the existing design evaluation systems cover other special consultants' views such as those of HVAC designers, structural engineers, and contractors. From an architect's view, this evaluation system checks the compliance of design objects represented by means of physical objects such as walls and windows and conceptual objects such as rooms as well, to the design criteria focused on accommodating human behavior, rather than other building performances such as sustaining building structures and maintaining indoor livability. As such, the system helps designers analyze and evaluate design solutions according to their original intent. The innovative points of this research lie in the following: (1) Unlike other inquiries, it addresses a systematic evaluation of building design from an architect's view focusing on the experiential quality of the built environment. This research demonstrates that such an evaluation becomes available by introducing human activity-based evaluation. (2) It can take a multi-agenda for several groups of different interests by providing an Aspect Model based on human activity-centered systematic translation of their design considerations and 3D model-based graphical representations into system readable ones. (3) As a result, it addresses the possibility of expanding the capability of the design evaluator from a mere code checker to a general design evaluator while simultaneously, enhancing the availability from stand alone to Internet based networking.

title Interactive 2D Constraint-Based Geometric Construction System
source Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 197-212
summary This paper presents a 2D Constraint-Based Geometric Construction System where positioning and manipulating geometry is very precise. An unusually simple interface makes this system particularly interactive and easy to use. In our approach, the geometry types supported are: points, lines, circles, ellipses, circular arcs and b-spline curves. All the fundamental topologic constraints, i.e. tangent, parallel, perpendicular, coincident and concentric, are provided. Metric constraints, i.e. dividing the shapes into equal parts or fixing the geometric parameters, are also provided. These constraints are automatically applied by the application in response to the implied intentions of the end- user. Dynamic modifications of partially dimensioned models are supported, whereby the design is modified while enforcing the constraints. A graph-constructive approach is used to solve the model. As we are dealing with partial modifications, this resolution technique is quite sufficient, and makes our system stable and flexible. Our approach focuses highly on interactivity. Positioning a shape constrained to another is made directly through the graphic interface. Constraint relaxation is also done by direct manipulations. Modifications are made by dragging the geometry, or by typing into a numerical panel displaying the free shape parameters. Again, existing constraints are maintained as those numbers are applied. Well -constrained and under-constrained problems are discussed. This approach was developed in Java, JDK 3.0.1 of SGI's Java software.

title Animation and Multimedia: Interviews at Five Large Los Angeles Firms
source ACADIA Quarterly, vol. 18, no. 3, pp. 1-3
summary Developments in digital media have created a myriad of tools to help architects communicate ideas. Three dimensional graphics software has revolutionized our ability to visualize our ideas. With the advent of animation and advanced methods of real time video presentation seem to have substantially upgraded the architects' tool chest. Significant advances have been made recently in bringing animation capabilities to the architectural desktop. To discover the level of integration of animation and multimedia in architectural firms, a series of interviews were conducted at five large Los Angeles firms. The interviews were structured with open-ended questions to allow the firms to emphasize their interests and capabilities. This document depicts the status of the current thinking at Gensler, Jerde, NBBJ, RTKL, and DMJM.

title Anticipating Reuse: Documenting Buildings for Operations Using Web Technology
source Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 54-65
summary This research explores the feasibility of Web technology as a means for delivering building information to better support facility operations. Our research proposes just-in-time (JIT) facility documentation as a pragmatic solution to the limitations of current as-built documents, allowing more effective reuse of building information. Our investigation addresses four issues: 1) what building information is needed for facility operations; 2) how the design and construction team can improve the format for delivering the building information to facility operators; 3) how current Web technology can store and deliver facility information in support of operations; 4) what is the mechanism of documenting building information using the Web technology. //

We surveyed literature, interviewed members of design and operations teams and reviewed current initiatives of industry and software vendors to identify problems with current practices. We also surveyed promising Web technologies and conducted experiments to determine how these technologies could help to solve the problems. We constructed a conceptual framework of JIT facility documentation as a solution to current information fragmentation problems. We developed a prototype of the JIT document system to demonstrate a “proof of concept” by using current Web technologies such as Autodesk’s DWF, Microsoft’s Active Server Pages, VB and Java script, and Access database to develop the prototype system. By dynamically composing HTML pages in response to task-specific requests, our prototype enables easy access and integration of a variety of building information to support facility operations.

title Evaluation of Spatial Perception in Virtual Environments
source III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 145-148
summary The 3D environments created by computers can be used as a powerful simulation tool for architecture, especially with inmersive devices, but it is necessary to know properly their spatial characteristics to use it effectively. It is also important to consider their possibilities in communication networks and their implications in contemporary architecture. For this reason, the goal of this research is to evaluate the perception of virtual architectonic spaces in relation to the perception of real architectonic spaces. This research is based on the comparison of experiences of university students in a real space (Entrance Hall of Faculty of Economy) and in the same space modeled by a computer. The evaluation considers tests with stereoscopic helmets and interactive navigation, making questionnaires to characterize the sensation of dimensions, relationships and time for an specific activity. The measuring of real and virtual spaces are made through references (furniture, textures, etc.) or by proportional relations between height, width and depth, in different patterns. The experience also reveals mental schemes to perceive the dimension of architectonic space and the orientation in a real and virtual environment. Besides, the research allows to relate the different levels of complexity and information with the understanding of real architectonic space and modeled space.

summary The modelization of an architectural fact, generated through a CAD program, doesn't have only the purpose of generating a virtual electronic, but a constructive scale model of geometric nature. It also implies, a conceptualization level and a posture in front of the pattern that makes thinking in other fields besides the formally constructive, such as: the descriptive and geometric patterns, the communicational and the symbolic pattern. We should understand the way the constructive thought is done the message of the model, either for the relationship with the environment and with the human scale, depends not only upon the author, but his elections will be intrinsically related with his cultural baggage, besides its geometric, graphical and technicians data. These databases condition the result of the model, for this reason we analyzed these relationships looking for a good handling of the cultural codes, to achieve a complete communication of the model. In these moments of the "global village", we should consider this problematic as a visceral topic of the architectural representation, to achieve an effective communication, among different cultures, of the models represented.

summary This piece proposes new strategies and pedagogic methodologies applied to the recognition and study of the subjacent measurements of the architectural projects to be created. This proposal is the product of pedagogic experience, which stems from this instructional team of the department of tri-dimensional models of electronic models. This program constitutes an elective track for the architectural major at the college of architecture, design, and urbanism of the University of Buenos Aires and housed at the CAO center. One of the requirements that the students must complete, after doing research and analytical experimentation through the knowledge that they acquired through this course, is to practice the attained skills through exercises proposed by the department in this case, the student would be required to virtually rebuild a paradigmatic architectonic piece of several sample architects. Usually at this point, students experience some difficulties when they analyze the existing documents on the plants, views, picture, details, texts, etc., That they have obtained from magazines, books, and other sources. Afterwards, when they digitally begin to generate basic measurements of the architectural work to be modeled, they realize that there are great limitations in the comprehension of the tri-dimensional understanding of the work. This issue has brought us to investigate and develop proposals of volumetric understanding of patterns through examples of work already analyzed and digitalized tri-dimensionally in the department. Through a careful study of the existent documentation for that particular work, it is evaluated which would be the paths and basis to adopt through utilizing alternative technologies to arrive at a clear reconstruction of the projected architectural work, the study gets completed by implementing the proposal at the internet site

summary This work presents the study and applied assays (or simulation tests) about the ordination of urban space in the region of Lagoa da Conceição. In the region pressures placed by the growth of urban area and urban network system are in contact conflict with a fragile ecosystem, and with a sustainable development based on tourism. Analysis procedures exploited different forms of Space Syntax trying to examine effects of spatial structure in relation to movement patterns of pedestrians and vehicles. This methodology allowed the comprehension of relation between spatial configuration, transport and soil use, and reveled the interdependence and performance of built space within the restrict regional scale (Lagoa da Conceição) and the total urban structure of the island. This understanding is not limited to the present. Is also includes the study of historic urban evolution, and simulation of existing projects for the future, being an important tool to support project decision process. Consequently, the obtained results bring a new approach for the problem, which makes possible the synthesis of design proposals verifying its implications and consequences.

title Investigating the Cognitive Behavior of Generating Idea Sketches. Neural Network Simulation
source CAADRIA 2000 [Proceedings of the Fifth Conference on Computer Aided Architectural Design Research in Asia / ISBN 981-04-2491-4] Singapore 18-19 May 2000, pp. 287-296
summary In idea sketches, there are a number of ambiguous shapes. Designers will associate and transform some shapes into others (Liu, 1993). Then, they evaluate these shapes in terms of functions and design requirements; furthermore, they would have generated other shapes that certified the design requirements (Huang, 1999). However, not only is the idea of design composed of one element, but also consisted of varied components. The purpose of this paper is to investigate how designers generate ideas of multi-component products, and to simulate this phenomenon by neural networks. At the same time, this paper attempts to study the design cognitive behavior of idea-generating stages, and explores the designers' cognitive phenomenon. Therefore, there are two stages in this paper: First, I conduct a cognitive experiment to realize how designers generate the multi-component product and acquire the sketches that designers generated. Second, I train the neural networks to simulate the behavior of idea generation and explore the cognitive phenomenon in design sketches. As a result, networks associate one shape that trained before, and then generate a complete idea. This phenomenon is similar to the cognitive behavior of designers who saw the ambiguous shape as one shape, which was retrieved from LTM. Moreover, the neural network is examined by a rectangle, which is totally different from the training patterns. The network will associate a confused shape. But the network will associate different shapes by adjusting some critical parameters. Designers can generate variable shapes from one shape, but the signal neural network can't simulate this kind of behavior. On the contrary, this paper proposes five sequential networks to generate variable shapes from the same shape and simulates how designers develop ideas.

summary Considering plane tessellation as a creative trigger that contributes to modular form design, a procedure to group 2D shapes and architectural 3D forms is developed. The particular case studied in this article is about Penrose tilings, which tessellate no-periodically, admitting a covering of the plane without using a constant distance repetition pattern. Procedures and rules for geometric generation and fractalization are analyzed. A technique to generate aperiodic tilings is proposed, so they will be used as a geometric precise support for the insertion of architectural objects that follow predetermined dimensional patterns, looking for constructive standardization without restricting diversity of cases. Using digital techniques, linear and central structures of groupings are analyzed. Both typologies are exemplified in various abstraction levels.

title Modular Architectural Groupings from Escher Periodic Tessellations
source AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999, pp. 205-219
summary One of the more interesting design techniques developed by Dutch graphic artist M.C. Escher consists in covering the plane with tiles containing patterns that repeats periodically. Modularity within shape grouping is extensively used, expressed by natural figures from the living world, and also from worlds of fantasy. This paper attempts to use Eschers's ideas as a source of inspiration to obtain modular shapes to conform groups with architectural issues. The task is to satisfy design requirements and to get repeatable unitary shapes, whose geometric description is modularly manipulated within area as well as perimeter. This should be done by two procedures: 1. from the components to the whole (from the tiles to the tiling): once the designer has defined a modular constructive unit (solving a particular situation), it is possible to repeat the unit to generate modular groups, knowing that they will fit perfectly among them, without gaps nor overlaps. 2. from the whole to the components (from the tiling to the tiles): defining a tessellation with the particular rules that drives close to the architectural solution, and getting the necessary units from the tiling. There are multiple architectural themes on which this should be performed. School class-rooms, habitation buildings, shopping center sites, hotel rooms, are examples of this statement. Analyzing procedures followed by the artist, particularly those using figures that tessellate the plane periodically, we'll be able to generate tiles with architectural shape by the same way, applying different symmetry rules. Once the rules to generate shapes of tiles are known, we work within area and perimeter to satisfy modularity requirements and to convert the tiling as a geometric precise support for the insertion of architectural objects that follow predetermined dimensional patterns. In order to illustrate these ideas an example of grouping repeatable habitation units is presented.

summary Spatial Design Ability (SDA) has been defined by the author (1983) as the capacity to anticipate the effects (psychological impressions) that architectural spaces or its components produce in observers or users. This concept, which requires the evaluation of spaces by the people that uses it, was proposed as a guideline to a Masters Degree Course in Architectural Design at the Universidad Autonoma de Aguascalientes in Mexico. The theory and the exercises required for the experience needed a model that could simulate spaces in terms of all the variables involved. Full-scale modeling as has been tested in previous research, offered the most effective mean to experiment with space. A simple, primitive model was designed and built: an articulated ceiling that allows variation in height and shape, and a series of wooden panels for the walls and structure. Several exercises were carried out, mainly to experience cause -effect relationships between space and the psychological impressions they produce. Students researched into spatial taxonomy, intentional sequences of space and spatial character. Results showed that students achieved the expected anticipation of space and that full-scale modeling, even with a simple model, proved to be an effective tool for this purpose. The low cost of the model and the short time it took to be built, opens an important possibility for Institutions involved in architectural studies, both as a research and as a learning tool.
