title	Dynamic Simulation of Neighborhood Water Use - A case study of Emirati neighborhoods in Abu Dhabi, UAE
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 197-206
summary	Being located in a hot, humid and arid bioregion, as well as having a unique religious and social context, the Gulf Cooperation Council cities pose significant challenges to the achievement of sustainable urban development. Using native neighborhoods in Abu Dhabi as a case study, this ongoing research aims to develop a design methodology which utilizes both qualitative and quantitative analysis towards the holistic, feedback driven design of new neighborhood typologies for the native population. This paper focuses on the methodology and application of a water use module which measures neighborhood scale indoor and outdoor water use, an area of simulation critical to developing sustainable neighborhoods for Arab cities, yet underrepresented within the literature. The water module comprises one part of a larger toolkit that aims to measure both environmental sustainability as well as social and cultural factors unique to the context of Abu Dhabi and the gulf region.

title	Capturing Designer Expertise : The CGEN System
source	18 p. : ill Pittsburgh, PA: Engineering Design Research Center, CMU, August, 1989. EDRC 18-08-89. includes bibliography.
summary	Knowledge-based systems are becoming pervasive in the computer-aided design area. For these systems to achieve satisfactory levels of performance large amounts of knowledge are necessary. However, the acquisition of knowledge is a difficult and tedious task. Automated knowledge-acquisition tools (AKAT) provide capabilities for quickly building and maintaining knowledge-bases. This paper describes the CGEN AKAT, which allows hardware designers, unfamiliar with artificial intelligence programming techniques, to deposit their expertise into a synthesis tool's knowledge-base. A set of experiments which tested CGEN's capabilities are presented. The experiments show that with CGEN hardware designers can produce high quality knowledge-bases

title	Data sharing for sustainable assessments: Using functional databases for interoperating multiple building information structures
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 193–202
doi	https://doi.org/10.52842/conf.caadria.2012.193
summary	This paper presents the development and implementation of an automatic sustainable assessment prototype using functional databases. For the practical purpose, we use Leadership in Energy and Environmental Design (LEED) as the exemplar standard to demonstrate the integrative process from building information aggregation to final evaluation. We start with a Building Information model, and use Construction Operations Building Information Exchange (COBie) as a bridge to integrate LEED requirements. At present, the process of sustainable building assessment requires information exchange from various building professionals. However, there is no procedure to manage, or use, information pertaining to sustainability. In our research, we translate rules from LEED into computable formulas and develop a prototype application to produce templates for LEED submission.

summary	The transition from conventional to sustainable building depends on a number of factors— technological, environmental, economic and social. From a computer-aided design perspective, the first two are perhaps the most significant. We are working on a project with an emphasis on developing tools, to evaluate environmental consequences for design decision-making. Our current thrust is given to reducing energy usage as well as carbon emissions in buildings.

summary	My point of departure is a long standing interest in close human communication. I have been much interested in the multiplicities of communicative levels between persons sharing daily life, e.g. spouses in a household. In the mid-sixties I was working with the first videotapings of marital dyads in a laboratory setting. The "interplay- analysis" which I developed at that time, however, was hampered by the lack of contextual naturalism in the setting. Since - working in the field of "altered states of consciousness" - I came to question the adequacy of studies of extra-ordinary states, in view of the lacking methodology for dealing even with the ranges of the variable ordinary states of mind over the 24-hour cycle in everyday life, and their potential relation to the micro-structure of the habitual ongoing activities of members of a household.

summary	The Internet has in just a few years radically changed the technical foundation for how the supply chain of scientific publications and teaching materials functions. As researchers we can with just a few clicks find a significant part of all the information we need for free on the World Wide Web. As teachers we can find huge amounts of digital material which can be downloaded or linked from the web and included in presentation overheads, or hyperlinked as reading material. Yet the business and legal (copyright issues) infrastructure has hardly changed and presents a barrier to innovation and reengineering of the overall process. This paper describes some recent trends in how the Internet influences these two fields (publication of research resuls and production of teaching material) as well as related developments in the organisation of software develop-ment, and discusses them both from an economic and philosophical perspective.

title	Mixed Reality Interactive Representations for the Assembly of a Custom Timber Tower
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 2, Graz, 20-22 September 2023, pp. 751–760
doi	https://doi.org/10.52842/conf.ecaade.2023.2.751
summary	In recent years, many projects have emerged testing the use of augmented reality (AR) and mixed reality (MR) systems in the custom design and fabrication of architectural projects at a variety of scales using digital and analog tools. This paper presents a series of MR systems for key modes of interactive representations in the assembly process of a custom timber tower, intending to expand an area of research on the use of MR as a critical medium for architectural representation in design customization. The series of MR systems were developed to assist and expedite the physical assembly of customized timber parts and connections for the large-scale tower with a small team of students and carpenters. The MR systems are built as interactive representations of the 3D digital design model, allowing the user to see connections in real-time on physical materials in order to perform collaborative preparation and assembly tasks with analog tools. Each MR system relied on a single user, wearing a HoloLens 2, to use hand gestures to place and interact with 3D Rhino model representations of the tower and individual parts overlaid in the physical context at 1:1 scale. The MR systems deployed as interactive 3D representations were evaluated at three key stages in the material preparation and assembly processes. The project tested the use of MR systems created for a series of tasks that enabled the fast assembly of the tower, which is almost 10 meters high. The outlook explores the perspective of how MR systems augment modes of architectural representation through human interaction, collaboration, and accessibility (also for non-expert users), using digital and analog tools, and how these systems provide greater agency for customization and variety in design and building.

summary	The operation target, of digital school building plans recording, in the area of the Education Secretary of Buenos Aires City, is to survey, organize and create the connectivity into a single database, for a great number of graphic and non graphic documents. The information stocked in vellum, paper, and blueprints, on different scales and formats, has been collected, classified and checked. A skillful cad operator staff, in a prolific environment generated by codes, rules and helped by several particular tools which include macros, routines and libraries, is doing the production of drawings. All the documents and their parent information, from any kind of source, establish the core of an important database. The new information scope has the flexibility and accessibility required for a permanent data updating and extension.

summary	On behalf of phenomenal advantages of project extranet technology You can believe in improving communication among professionals in design and construction industry. But until now, the reality appears not as good. It is technological irony, as evidenced in below presented survey, that advanced solutions for a better collaboration may set up unbreakable barriers. Therefore knowledge of everyday reality in the field of webbased collaboration tools use is critical to all participants of this process, commercial as well academic ones. It is especially important to all European professionals, who are aware of consequences of extending in nearest future borders of European Union, the second biggest market in the world.

title	Texture and Reflection in Computer Generated Images
source	Communications of the ACM 19 10 542-547
summary	In 1974 Catmull developed a new algorithm for rendering images of bivariate surface patches. This paper describes extensions of this algorithm in the areas of texture simulation and lighting models. The parametrization of a patch defines a coordinate system which is used as a key for mapping patterns onto the surface. The intensity of the pattern at each picture element is computed as a weighted average of regions of the pattern definition function. The shape and size of this weighting function are chosen using digital signal processing theory. The patch rendering algorithm allows accurate computation of the surface normal to the patch at each picture element, permitting the simulation of mirror reflections. The amount of light coming from a given direction is modeled in a similar manner to the texture mapping and then added to the intensity obtained from the texture mapping. Several examples of images synthesized using these new techniques are included.

title	Simulation of Wrinkled Surfaces
source	Computer Graphics 12 3. 286-292
summary	Computer generated shaded images have reached an impressive degree of realism with the current state of the art. They are not so realistic, however, that they would fool many people into believing they are real. One problem is that the surfaces tend to look artificial due to their extreme smoothness. What is needed is a means of simulating the surface irregularities that are on real surfaces. In 1973 Ed Catmull introduced the idea of using the parameter values of parametrically defined surfaces to index into a texture definition function which scales the intensity of the reflected light. By tying the texture pattern to the parameter values, the texture is guaranteed to rotate and move with the object. This is good for showing patterns painted on the surface, but attempts to simulate rough surfaces in this way are unconvincing. This paper presents a method of using a texturing function to perform a small perturbation on the direction of the surface normal before using it in the intensity calculations. This process yields images with realistic looking surface wrinkles without the need to model each wrinkle as a separate surface element. Several samples of images made with this technique are included.

title	Planning-oriented building surveying - Modules in the computer aided architectural planning process of existing buildings
source	Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 144-149
doi	https://doi.org/10.52842/conf.ecaade.2001.144
summary	Activities in the building industry in Germany concentrate increasingly on a combination of renovation and new-build. A prerequisite for computer-aided planning in the context of existing buildings is both the use of on-site computer aided surveying techniques and the integration of all professional disciplines in an integrated information and communication system. Current approaches to these issues are unsatisfactory. Methods and techniques in renovation work are being investigated as part of ongoing research at the Bauhaus- Universität Weimar (SFB524 - “Collaborative research center 524 „Materials and Structure in Revitalization of Buildings”). A sub-group (SFB524 - D2 „Planning-Relevant Digital Building Surveying and Information System”) is currently investigating the possibilities of computer-aided building surveying and of joint communcation platforms for engineering disciplines (www.uni-weimar.de/sfb: May 2001). The objective is the development of a general approach for the renovation of buildings. The paper discusses concepts and requirements for a computer-aided system supporting the entire surveying process from the initial site visit to its use in a CAD system.

title	A Generalization of Algebraic Surface Drawing
source	ACM Transaction on Graphics, vol. 1, no. 3, pp. 235-256, 1982
summary	The technology of creating realistic and visually interesting images of three- dimensional shapes is advancing on many fronts. One such front is the develop- ment of algorithms for drawing curved surfaces directly from their mathematical definitions rather than by dividing them into large numbers of polygons. Two classes of surfaces which have received attention are the quadric and the bivariate parametric surfaces. Bivariate parametric surfaces are generated by three func- tions of two variables (most popularly polynomials), as the variables take on different values. Algorithms dealing with such surfaces are due to Catmull; Lane, Carpenter, Whitted and Blinn; and Clark.

summary	Fibre composites are synthetic in their composition, but structured similarly to biological materials, as fibre and matrix. While the fibre constituent in Fibre-Reinforced Polymer (FRP) is mostly used under the form of fabrics, its standard fabrication processes do not rely on its inherent textile attributes. Embedding the fabric qualities in the fabrication of architectural FRP can potentially introduce concepts and properties of biological materials into engineered fibre composites; it can promote and enable the generation of an architectural complexity of a biological nature. The paper presents Fabric Materiality as a framework for a new design and fabrication process and demonstrates through a case study its integration in the fabrication of architectural FRP elements to achieve a complex structure with bio-inspired properties.
