title	Structure at the Velocity of Architecture

source	ACADIA 10: LIFE in:formation, On Responsive Information and Variations in Architecture [Proceedings of the 30th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-4507-3471-4] New York 21-24 October, 2010), pp. 218-226
summary	This paper outlines a digital design workflow, utilized by the authors, which actively links the geometry platforms being utilized by architects with tools for structural analysis, design, form-finding, and optimization. This workflow leads to an accelerated generation and transfer of information to help guide and inform the design process. The engineering team is thus empowered to augment the architect’s design by ensuring that the design team is conscious of the structural implications of design decisions throughout the design process. A crucial element of this design process has been the dynamic linkage of parametric geometry models with structural analysis and design tools. This reduces random errors in model generation and allows more time for critical analysis evaluation. However, the ability to run a multitude of options in a compressed time frame has led to ever increasing data sets. A key component of this structural engineering workflow has become the visualization and rigorous interpretation of the data generated by the analysis process. The authors have explored visualization techniques to distill the complex analysis results into graphics that are easily discernable by all members of the design team.

title	Da Perspectiva Artificialis ao Cyberespaço: Motor Gráfico e a Visualisação Interativa da Luz Natural no Interior do Edificio [From perspectiva artificialis to cyberspace: Game-engine and the interactive visualization of the natural light in the interior of the building]
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	In order to support the conceptual design, the architect used throughout the years, mockups - scaled physical models - or perspective drawings that intended to predict architectural ambience before its effective construction. This paper studies the real time interactive visualization, focused on one of most important aspects inside building space: the natural light. Although the majority of physically-based algorithms currently existing was designed for the synthesis of static images which may not take into account how to rebuild the scene - in real time - when the user is doing experiments to change certain properties of design.

title	Knowledge Nodes
source	I. Smith (ed) Artificial Intelligence in Structural Engineering, Springer, Berlin, pp. 197-213
summary	Today most of the information we produce is stored digitally. We are slowly forced to leave behind us thinking about information as something stored in physical containers as books, drawings etc. We make it possible to dynamically create logical containers of information on the fly. The paper focuses on how we in the future can aggregate, classify and generalize digitally stored information in order to make it more accessible and how we can define underlying knowledge container models to support knowledge discovery and collaboration. Examples are picked from ongoing research and the outcomes are generally valid and in particular for the structural engineering field.

title	Models of Collaboration for Designers in a Computer Supported Environment
source	Formal Aspects of Collaborative CAD, IFIP, pp. 99-108
summary	The development of models for Computer Mediated Collaborative Design (CMCD) provides guidelines for the continuing development of technology and tools for CMCD. In order to develop models for CMCD, a range of experiments and research objectives needs to be developed. The current literature around models for CMCD is still quite informal and descriptive. In this paper, we define the roles and types of models for CMCD. We propose a framework for understanding the contribution such models can make that considers two phenomomena in CMCD: communicating and designing. We present some descriptive models from design research, CSCW research, and CMCD research and show how these models address communicating and designing.

title	Advanced Design Tools for Energy Conscious Design
source	Paper to Royal Society
summary	This paper is concerned with building energy simulation and the prospects for the delivery of a new generation of simulation based, valid and easy to use design tools to the building construction industry. The issues relating to design tools development and use are discussed and the present state-of-the-art is described. Some medium to long term developments are then identified, including an intelligent front end and the notion of an advanced machine environment for the construction and maintenance of future models concerned with building energy and environment. The mechanisms for technology transfer are identified and experiences recounted of the first two years operation of an innovatory energy design advisory service. The paper finishes with a look to the future of the information technologies in building design.

title	Virtual components consisting of form, function and behavior
source	Automation in Construction 8 (3) (1999) pp. 351-367
summary	Software can produce a product model of a building as a consequence of the designers' actions in drawing and evaluating the design. The actions of the designer include interpreting, predicting and assessing the emerging design and describe the building in terms of forms, functions and behaviors. A software prototype has been implemented that incorporates this understanding of the design process in the field of building design. It employs object-oriented classes to represent forms, functions and behaviors. As a software user draws and interprets the design for multiple evaluation issues, the software creates a unique `virtual component' for each entity. During automated reasoning to evaluate the emerging design, virtual components collect and organize form, function and behavior instances to describe the parts of the building. In comparison to other product models, our approach, which we refer to as a `Virtual Product Model', better accommodates change, provides increased support for the design process and enriches the product representation by including function and behavior.

title	Parsimonious Models of Urban Space

summary	This paper sets out an approach to urban modelling derived from early work with cellular automata and agglomeration models. In these cases the models are an example of distributed representation, where the rules built in to the model are replicated in all the discrete components of the model be they cells or agents. This is the classic AI. / AL paradigm of emergent systems. The paper describes the main structure of the models, and presents examples of the use of this modelling process in design education, pointing out the way dynamic models allow mapping on to interesting speculations about the dynamic of the city, and its social systems. The paper ends with a report on the use of such models as a design decision support system and how they will be used in planned work in master planning in the London Thames gateway area under the UK govt. sustainable communities initiative.

title	Discrete B-Splines and Subdivision Techniques in Computer-Aided Geometric Design and Computer Graphics
source	computer Graphics and Image Processing. October, 1980. vol. 14: pp. 87- 111 : ill. includes bibliography
summary	The relevant theory of discrete B-splines with associated new algorithms is extended to provide a framework for understanding and implementing general subdivision schemes for nonuniform B-splines. The new derived polygon corresponding to an arbitrary refinement of the knot vector for an existing B-spline curve, including multiplicities, is shown to be formed by successive evaluations of the discrete B-spline defined by the original vertices, the original knot vector, and the refined knot vector. Existing subdivision algorithms can be seen as proper special cases. General subdivision has widespread applications in computer-aided geometric design, computer graphics, and numerical analysis. The new algorithms resulting from the new theory lead to a unification of the display model, the analysis model, and other needed models into a single geometric model from which other necessary models are easily derived. New sample algorithms for interference calculation, contouring, surface rendering, and other important calculations are presented

title	An Efficient Radiosity Approach for Realistic Image Synthesis
source	IEEE Computer Graphics and Applications March, 1986. vol. 6: pp. 26-35 : col. ill. includes bibliography.
summary	The radiosity method models the interaction of light between diffusely reflecting surfaces and accurately predicts the global illumination effects. Procedures are now available to simulate complex environments including occluded and textured surfaces. For accurate rendering, the environment must be discretized into a fine mesh, particularly in areas of high intensity gradients. The interdependence between surfaces implies solution techniques which are computationally intractable. This article describes new procedures to predict the global illumination function without excessive computational expense. Statistics indicate the enormous potential of this approach for realistic image synthesis, particularly for dynamic images of static environments

source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 360-364
summary	The number of different designers with different competencies collaborating in a building project is today conspicuous. An undesired consequence is the possible rise of conflicts between decisions taken independently by more than one specialist on the same building object. The early detection of such conflicts is then one of the most important features in collaborative design. Moreover, of great interest would be the possibility not only of automatic detection but also of solution proposal of at least the most manageable of those conflicts. In this perspective smart models of building components could be very useful. This is possible giving the building elements, represented as objects, the specific intelligence. A simple example of this possibility is given in this paper. In a precedent work we proposed a way of managing elementary spatial conflicts between building components tending to occupy the same spaces. The automatic detection derived from the previous declaration of two levels of constraints (soft constraint and hard constraints) in such way that a violation of them could be immediately signaled to the actor wanting to take the decision triggering the conflict. In this paper the topic is the consequences of the rise of a spatial conflict (occupation of the same space) between a column of a spatial frame of columns and beams, and another building object of any sort subject to a soft or hard constraint. The procedure identifies the minimum displacement of the two objects, propagates the column displacement to the other structural elements connected to it and checks the feasibility of the new configuration of the structural schema both with regard to the possible rise of new conflicts and with the compliance to previous structural criteria.

summary	The paper presents an approach to the problems of architectural design aided by Artificial Intelligence techniques that can solve the difficulties related to combinatorial explosion, often encountered in the past. Three expert systems, dubbed "reasoners", capable of some elementary design work and a hypothesis for their interaction have been developed. Reasoner A has an "analogical" view of space. A notion of conflict, managed by means of fuzzy logic, has been introduced. It corresponds, in an intuitive and straightforward fashion, to the common notion of conflict or contradiction in real space as a consequence of improper overlapping of actual physical objects or of their functional pertinence. Reasoner B works on formalized models of building objects. It designs new patterns from given patterns taken as defaults. Reasoner C picks up from an archive of patterns the one which best suits a list of given goals. Design is the result of interaction between the three reasoners. Finally, the proposed schema raises questions about formal structures ("images") and about the nature of culturally-linked options ("memory") on which some preliminary considerations are made. Prototypes of the reasoners are operating at the Instituto di Edilizia of the University of Ancona, Italy.

title	Coordinating Atypical Architectural Precast Concrete Façades - Two categories
doi	https://doi.org/10.52842/conf.ecaade.2019.2.261

summary	This research focuses on issues of coordination between designers and fabricators during early design. The aim of this work is to improve representations, enable more informed conversations, and streamline exchanges of digital models. In order to show the potential of the work, research is focused on architectural precast concrete facades. Previous work established methods for linking "global" and "local" parametric models of architectural intent and corresponding components, describing processes of mapping from individual custom panels to diagrammatic façade surfaces and vice-versa. Such mapping may be considered "direct," wherein individual panel boundaries - defined by surface patterning - allow simple mapping of data from global to local or from local to global descriptions. However, there are some buildings with architectural precast concrete façades which do not permit direct relationships between global and local descriptions. These atypical facades require "indirect" maps containing additional layers of information in order to coordinate global and local descriptions. This paper describes two categories of these indirect scenarios: "panelization" and "patterns across panels."

summary	As educators, we have been witness and party of ICT’s application in teaching architecture. From computer assisted design, representation models, dynamic and interactive visualization, until the arrival of digital fabrication, the incorporation of augmented reality and the interaction on mobile devices. Reflections on digital technology have generated discussions on architectural theory in order to find the source of architectural language inspirations. We find ourselves today in a context of important intellectual renewal aimed at the design in freedom.

title	Shade Trees
source	Computer Graphics, Vol. 18, No.3, pp.223-23 1
summary	Shading is an important part of computer imagery, but shaders have been based on fixed models to which all surfaces must conform. As computer imagery becomes more sophisticated, surfaces have more complex shading characteristics and thus require a less rigid shading model. This paper presents a flexible tree-structured shading model that can represent a wide range of shading characteristics. The model provides an easy means for specifying complex shading characteristics. It is also efficient because it can tailor the shading calculations to each type of surface.

title	Designing Information Technology in the Postmodern Age
source	The MIT Press, Cambridge, Ma and London UK
summary	Designing Information Technology in the Postmodern Age puts the theoretical discussion of computer systems and information technology on a new footing. Shifting the discourse from its usual rationalistic framework, Richard Coyne shows how the conception, development, and application of computer systems is challenged and enhanced by postmodern philosophical thought. He places particular emphasis on the theory of metaphor, showing how it has more to offer than notions of method and models appropriated from science. Coyne examines the entire range of contemporary philosophical thinking -- including logical positivism, analytic philosophy, pragmatism, phenomenology, critical theory, hermeneutics, and deconstruction -- comparing them and showing how they differ in their consequences for design and development issues in electronic communications, computer representation, virtual reality, artificial intelligence, and multimedia. He also probes the claims made of information technology, including its presumptions of control, its so-called radicality, even its ability to make virtual worlds, and shows that many of these claims are poorly founded. Among the writings Coyne visits are works by Heidegger, Adorno, Benjamin, Gadamer, Derrida, Habermas, Rorty, and Foucault. He relates their views to information technology designers and critics such as Herbert Simon, Alan Kay, Terry Winograd, Hubert Dreyfus, and Joseph Weizenbaum. In particular, Coyne draws extensively from the writing of Martin Heidegger, who has presented one of the most radical critiques of technology to date.
