title	Using Computer Game to Develop Advanced AI
source	Computer, 34 (7), July pp. 70-75
summary	Although computer and video games have existed for fewer than 40 years, they are already serious business. Entertainment software, the entertainment industry's fastest growing segment, currently generates sales surpassing the film industry's gross revenues. Computer games have significantly affected personal computer sales, providing the initial application for CD-ROMs, driving advancements in graphics technology, and motivating the purchase of ever faster machines. Next-generation computer game consoles are extending this trend, with Sony and Toshiba spending $2 billion to develop the Playstation 2 and Microsoft planning to spend more than $500 million just to market its Xbox console [1]. These investments have paid off. In the past five years, the quality and complexity of computer games have advanced significantly. Computer graphics have shown the most noticeable improvement, with the number of polygons rendered in a scene increasing almost exponentially each year, significantly enhancing the games' realism. For example, the original Playstation, released in 1995, renders 300,000 polygons per second, while Sega's Dreamcast, released in 1999, renders 3 million polygons per second. The Playstation 2 sets the current standard, rendering 66 million polygons per second, while projections indicate the Xbox will render more than lOO million polygons per second. Thus, the images on today's $300 game consoles rival or surpass those available on the previous decade's $50,000 computers. The impact of these improvements is evident in the complexity and realism of the environments underlying today's games, from detailed indoor rooms and corridors to vast outdoor landscapes. These games populate the environments with both human and computer controlled characters, making them a rich laboratory for artificial intelligence research into developing intelligent and social autonomous agents. Indeed, computer games offer a fitting subject for serious academic study, undergraduate education, and graduate student and faculty research. Creating and efficiently rendering these environments touches on every topic in a computer science curriculum. The "Teaching Game Design " sidebar describes the benefits and challenges of developing computer game design courses, an increasingly popular field of study

title	CAD in Practice Profile: Polshek Partnership Architects LLP
doi	https://doi.org/10.52842/conf.acadia.1999.010
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)

doi	https://doi.org/10.52842/conf.acadia.1999.015.2
source	ACADIA Quarterly, vol. 18, no. 1, pp. 15-18
summary	R.M. Kliment and Frances Halsband Architects (KHA) is a firm recognized—among many outstanding achievements— for designing award-winning computer science centers at major universities (e.g., Columbia, Dartmouth, Princeton). With that design experience, it is no surprise that the firm has adopted an aggressive stance towards its own use of information technology (IT). One indication of this proactive approach to technology is that KHA, with a total staff of 33, carries a full-time CAD/systems manager position, as contrasted with the A/E-firm industry-wide average of one such full-time equivalent staff position for every 40 total employees. In effect, the firm has set its investment in and commitment to the role of IT at a rate twenty percent higher than the industry average. Such above-average investment in IT is consistent with other high-profile design firms that have won the prestigious Firm Award of the American Institute of Architects. (1)

title	Digital Environments for Early Design: Form-Making versus Form-Finding
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 235-242
summary	Design ideas, like scientific theories, are falsifiable hypotheses subject to testing and experimentation and—if need be—replacement by newer ideas or theories. Design ideas also are known through distributed cognition, in which a mental construct and an external representation complement each other. Representations may be categorized along the axes 2D-3D and Analog-Digital, plus a proposed third axis from Form-Making to Form-Finding. In Form-Making, the mental construct component (of distributed cognition) arises before the representation. In Form-Finding, representation arises before the mental construct. All media of representation have different affordances. Certain media and representations afford Form-Making more so than Form-Finding; and vice versa. Design educators, students and practitioners will benefit from conscious, systematic choice of media and methods that afford an appropriate range of Form-Making and Form-Finding behavior when proposing and testing design ideas.

title	Algorithm and Context: A Case Study of Reliability in Computational Daylight Modeling
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 331-344
summary	The systematic use of reliable modeling data is believed to improve the building design quality. The key term here is "reliability". There is general agreement that reliability in the context of modeling- assisted CAAD depends on the accurate description of both contextual parameters (climate, site, etc.) and ~building features (geometric and non-geometric properties) as well as the validity of the underlying simulation algorithms. In this paper, we specifically address the importance of detailed contextual information and computational algorithms for the reliability of the daylight modeling results.

title	Comprehend the Term ‘Info-City’ - A Comparison between Two Primary Cities in Taiwan
doi	https://doi.org/10.52842/conf.ecaade.2004.508
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.

title	From Digital to Real: Inmotics and Parametricism for Urban Transformation
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 1005–1016
summary	Our research team develops sustainable and inclusive typologies of micro-architecture. These micro-architectures, aided by cutting-edge technologies, give room to more inclusiveness and functional-ductility. We are convinced that nothing is static, there is not just a single possible future. Because of that, we generate real/virtual architectures that do not respond only to a single type of user, place or use. In this case, we introduce a typological model focused on health and wellness services, currently under development by parametric design. Located in the city of Córdoba, Argentina and placed near public parks (where many citizens practice sports and recreational outdoor activities)). We use energy-efficient local technology to power devices that adapt to local weather; moreover, the equipment provides performance data via audio, visual and tactile outputs, and in adjustable-position devices.

source	CAAD futures ‘87 [Conference Proceedings / ISBN 0-444-42916-6] Eindhoven (The Netherlands), 20-22 May 1987, pp. 71-80
summary	Drawing in all its various forms, from freehand sketching to detailed technical layout, is a type of modelling that designers find indispensable. In many cases, indeed, drawing is the only form of external modelling a designer uses. It has two basic functions: to assist in the externalisation and development of mental concepts and to help in the presentation of these concepts to others. The current thrust of work in computer graphics - although valuable - tends to concentrate almost exclusively on the presentation aspects and it is now possible to create images almost resembling photographs of real objects as well as production drawings of great accuracy and consistency. This paper summarises some of this presentation work as well as developments which might go further in assisting the activities and processes of design.

summary	In this paper we describe the use of media and communication technologies with a special notification on video systems for the design of a technological enhanced environment. We make suggestions how architects can design environments that are more flexible and dynamic. These environments are adapted to our changing social and cultural trends. Developments in media and communication technologies allow extending the real world to a so called Tele Reality. These environments will have a certain degree of intelligence provided via computer performance. Humans will be able to receive information form anywhere and at anytime. The focus is on expanding the availability of human resources.

summary	This year, for the first time in history more people are living in cities than in the country. This fact induced us to look at the topic of city modeling from different sides. In this paper we introduce novel approaches that contribute to the generation and visualization of dynamic complex urban systems. We distinguish reality-based and generic city models. On the one hand we look a three dimensional models of urban environments. On the other hand we are looking at the key challenges and trends that will shape future cities. We are drawing parallels to functional models of brain circuitry. City modeling as a case in point provides the basis for our research to arrive at a transdiciplinary theory of design and modeling.

source	M. Haeusler, M. A. Schnabel, T. Fukuda (eds.), Intelligent & Informed - Proceedings of the 24th CAADRIA Conference - Volume 1, Victoria University of Wellington, Wellington, New Zealand, 15-18 April 2019, pp. 103-112
summary	Complex brick construction is defined by its relationship to labor; it requires skilled workers in planning, manufacturing and assembly. In the modern era, this has been perceived as a significant drawback, and as such has resulted in brick construction being partially superseded by more rapid methods of fabrication, despite its inherent robustness and longevity. This paper describes the second stage of an ongoing research project which attempts to revitalize the material system of the brick special through the development of an intelligent 3d printing method that works in conjunction with a layman assembly procedure for a new class of self-supporting nonstandard brick structures. In this project, an indexed and geometrically informed jointing system, together with a parametric and digital workflow, enables rapid assembly on site without a requirement for complex site setup or skilled labor.

summary	This paper describes a design approach for a new urban building typology for Shanghai utilizing a set of parametric design techniques to arrive at an alternative solution to current models of urbanization. The goal in this approach was to find a solution that is adaptable and sensitive to the urban environment and has the capacity to preserve historic urban street patterns. The approach included an understanding of the historic urban fabric of Shanghai, a respective plot analysis and the development of a computational method to produce a new urban type. The parametric set-up was build upon an analytical workflow with integrated feedback procedures that informed the design exploration and resulted in multiple design solutions.

summary	In 2018 after Typhoon Mangkhut hit Hong Kong, the city lost around 80% of its existing corals. As a consequence, a team consisting of marine biologists and architects have developed a series of performative structures that will be deployed in Hong Kong waters intending to aid new coral growth over the coming years. This paper describes the present research that focuses on the design and fabrication of artificial reef structures utilizing a robotic 3d clay printing method addressing the specificities of Hong Kong marine ecologies. The paper describes further the algorithmic design methodology, the optimization processes in the generation of the printing path, and the methodology for the fabrication processes during the production cycle to achieve even quality and prevent cracking during the drying process.

summary	Coral reefs are some of the most diverse ecologies in the marine world. They are the habitat to tens of thousands of different marine species. However, these wildlife environments are endangered across the globe. Recent research estimates that around 75 percent of the remaining coral reefs are currently under threat. In 2018 after a devastating storm, Hong Kong lost around 80% of its existing corals. Consequently, a team consisting of marine biologists and architects at The University of Hong Kong has developed a series of performative structures that have been deployed in the city's waters in July 2020, intending to aid new coral growth over the coming years. The project was commissioned by the Agriculture, Fisheries, and Conservation Department (AFCD) and is part of an ongoing active management measure for coral restoration in Hoi Ha Wan Marine Park in Hong Kong. The following objectives were defined as part of the design and fabrication research of the project. To develop a design strategy that builds on the concept of biomimicry to allow for complex spaces to occur that would provide attributes against the detachment of the inserted coral fragment, hence could enhance a diverse marine life specific to the context of the cities water conditions. To generate an efficient printing path that accommodates the specific morphological design criteria and ensures structural integrity and the functional aspects of the design. To develop an efficient fabrication process with a DIW 3D printing methodology that considers warping, shrinkage, and cracking in the clay material. The research team developed a method that combined an algorithmic design approach for the design of different geometries with a digital additive manufacturing process utilizing robotic 3D clay printing. The overall fabrication strategy for the complex and large pieces sought to ensure structural longevity, optimize production time, and tackle the involved double-sided printing method. Overall, 128 tiles were printed, covering roughly 40sqm of the seabed.

doi	https://doi.org/10.52842/conf.ecaade.2015.1.237
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 1, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 237-243
summary	In the early stages of the design process, the conceptual idea of the envisaged building and its design parameters is still vague and incomplete. While the built environment, the end product of this design process, can be represented concretely in the form of drawings or computer models, the initial design idea can usually only be formulated abstractly, for example as schematic functional descriptions or as topological constellations of spaces. In this paper we discuss the use of reference projects to support the design process along with ways of formalising spatial configurations and their use in the design process, and examine how these can be supported using software tools. We discuss the elaboration of requirements for such software tools and their implementation as plug-in to facilitate a seamless process from analysis to evaluation in a parametric design environment. By way of example, we describe selected functionality of a plug-in developed for “Grasshopper” and “Rhino 3D” to support the design process in the early conceptual stages.
