title	Computer Architectural Representation - Applying the VOIDs Framework to a Bridge Design Scheme
doi	https://doi.org/10.52842/conf.ecaade.1999.387

summary	A virtual environment presents sensory information and visual feedback to the user in order to give convincing illusion of an artificial world. In the architectural profession, the spatio-temporal metaphor in itself constitutes significant information retrieval, because we understand architecture by seeing it. This paper attempts to understand, and then to analyse the characteristics of representation of architectural models in virtual environments. We will examine the use and creativity of current computer generated architectural presentation in virtual environments. Our observations will be applied to the modelling of a bridge in Castlefield, Manchester, and evaluated by a group of students within the School of Architecture at Sheffield University. The conclusion of this paper will be the presentation of a conceptual structure for representing architectural models in virtual environments. This paper also explores the tension between the correspondence and constructivist views of representation. The correspondence view of representation relies on the idea that a representation corresponds to what is out there in the world. The constructivist view of representation advocates that any actual interpretation would depend on the context of their social and cultural backgrounds. However, the authors believe there should be a combination of these two views for architectural representation in virtual environments, and a framework developed by the authors - VOIDs will be presented.

title	Contextual Hypermedia in the Design Studio
doi	https://doi.org/10.52842/conf.ecaade.1993.x.i7f
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	The focus of this paper is on the development and use of hypermedia applications for the presentation of design studio projects, based upon the author's own recent experience of teaching CAD at both undergraduate and postgraduate level. The contention of this paper is that this activity cannot be reduced to routine Hypercard stack development. Instead, the development of applications in this area need to give support to the expression of the design-theoretical issues that are central to the presentation of any design studio project, by exploiting the many issues of concern that are emerging from the field of human- computer interaction (HCI) The hypermedia application i.e. in this case design-theoretical views of a design project, will inevitably influence the specification of a user-interface, and hence the presentation and appearance of the design project. This paper will investigate the extent to which the interface can be separated out from the application and the converse issue namely, whether non-contextual hypermedia environments restrict design applications.

title	Giving Colour to Contextual Hypermedia
doi	https://doi.org/10.52842/conf.ecaade.1994.191
source	The Virtual Studio [Proceedings of the 12th European Conference on Education in Computer Aided Architectural Design / ISBN 0-9523687-0-6] Glasgow (Scotland) 7-10 September 1994, pp. 191-200
summary	Design development evolves within design contexts that require expression as much as the design itself, and these contexts often constrain any presentation in ways that are not usually explicitly thought of. The context of a design object will therefore influence the conceptual ways of thinking about and presenting this object. Support in hypermedia applications for the expression of the colour context, therefore, should be based upon sound theoretical principles to ensure the effective communication of design ideas. Johannes Itten has postulated seven ways to communicate visual information by means of colour contrast effects, each of which is unique in character, artistic value, and symbolic effect. Of these seven contrasting effects, three are in terms of the nature of colour itself: hue, brightness, and saturation. Although conventional computer graphics applications support the application of these colour properties to discrete shapes, they give no analysis of contrasting colour relationships between shapes. The proposed system attempts to overcome this deficiency. The remaining four contrast effects concern human psychology and psychophysics, and are not supported at all in computer graphics applications. These include the cold-warm contrast, simultaneous contrast, complementary contrast, and the contrast of extension. Although contrast effects are divided into the above seven aspects, they are also related to one another. Thus, when the hue contrast works, the light-dark contrast and cold-warm contrast must work at the same time. Computational support for these colour effects form the focus of this paper.

title	Early Design Clustering Method Considering Equitable Daylight Distribution in The Adaptive Re-Use of Heritage Buildings
doi	https://doi.org/10.52842/conf.ecaade.2023.2.105
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. 105–114
summary	The re-use of existing buildings is gaining importance worldwide in the context of the carbon reduction efforts. In the case of Québec City there is a large number of heritage buildings that are currently unused. There are ongoing projects to breathe new life in these buildings, mainly by converting them in residential units. At the same time there is a growing preoccupation in Québec province towards energy efficiency and proper daylighting in both new and existing buildings. This is reflected in the emergence of new regulations concerning new buildings. In relation to existing buildings there are no regulations, but optimal daylight is a desired feature that can contribute significantly to the quality and attractiveness of newly designed spaces in the existing premises. In the case of heritage buildings, the additional conceptual challenge is to create properly daylit spaces while maintaining the character defining elements of the building, including facades and openings. Therefore, a digital workflow was developed to be integrated in the earliest schematic phase of design to ensure an equitable distribution of existing daylight in the newly created spatial units of heritage buildings. The method is based on an adapted constrained K-means clustering algorithm that works on daylight simulation data.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	In the dialectic formal Eisenman, the procedures for projecting initially start from the consideration of architectural form as a transformation of a solid geometric pre-existing. Subsequently, the form is timeless, decomposed into spatial entities, non-specific, requiring the intellectualization of the process as an alternative to emotion perception. From the eighties, mediated by computer resources, self-referentiality is the keynote of the representational process and architectural experience. The search houses poetic diagrams as procedures for projecting computer, tangent now the concept of trail’ Derrida responsible for the intelligibility and readability of architecture, sometimes grotesque, or a rationale that contains the irrational.

summary	This paper presents a novel method for the integrated design, optimization and fabrication of space-frame structures in an autonomous, digital process. Comparative numerical studies are presented, demonstrating achievable mass reduction by application of the method by comparison to equivalent to normative space truss designs and dimensions. As such, a principal digital fabrication and assembly scheme is developed, where an architectural design methodology relative to the described process is established, and the proposed process is demonstrated through scaled digital fabrication experiments.

title	Advancing 3D Concrete Printing for Affordable Housing: A Shape Grammar-Based Approach to Print Spanning Roof Structures
source	C+++: Computation, Culture, and Context – Proceedings of the 11th International Conference of the Arab Society for Computation in Architecture, Art and Design (ASCAAD), University of Petra, Amman, Jordan [Hybrid Conference] 7-9 November 2023, pp. 344-364.
summary	3D concrete printing (3DCP) technology is expected to address the construction industry's inefficiency, lack of skilled labor, and safety concerns, while tackling the housing shortage due to global population growth. Current applications in academia and industry have mainly focused on fabricating wall elements, which do not fulfill the potential of this technology to fully automate the construction process, including enclosures. In concrete construction, formwork is an essential part that fundamentally influences labor needs, quality, time, and cost. Many building components, such as walls, beams, columns, and prefabricated blocks, have been successfully printed without formwork using various additive manufacturing (AM) techniques for 3DCP. However, due to a 60-degree printing angle restriction when using a horizontal slicing technique and a corbelling printing method, to print spanning structures without formwork remains a challenge. Most state-of-the-art studies in 3DCP have focused on developing strategies to fabricate formwork, rather than developing new techniques for printing them without formwork. This research aims to leverage the power of shape grammar to overcome the challenges of printing spanning roof structures in 3DCP. By drawing inspiration from historical structures, we propose a multi-directional printing approach, integrating corbelling, radial, and inclined slicing techniques for toolpath design. Our objective is to establish shape grammar rules to break down enclosures into printable patches, design corresponding toolpaths using various slicing techniques, and validate the effectiveness of this approach by physically fabricating a prototype. To achieve this objective, an algorithm, incorporating shape grammar rules and numerical modelling software, to optimize the 3D concrete printing process for spanning roof structures was developed. Through this generative design system, designers can efficiently generate diverse and sustainable roof designs, specifically tailored for affordable housing solutions.

summary	This paper outlines a developing teaching and research pedagogy being developed at an educational institution in the United Arab Emirates that resists contemporary models of Computational Orientalism. The paper describes that exploring the space between Middle-Eastern material culture and contemporary computational design methodologies as generative, systemic, and adaptive conditions allows for the development of a material culture that is both local and driven by the computational zeitgeist. More specifically, the paper outlines the historical relevance of the computational spline and how it is being explored to develop a novel material culture through parametric models and physics-based systems.

title	Information Modelling and Sharing in the CO-CIS Project
source	The Int. Journal of Construction IT 6(2), pp. 67-85
summary	Complex information structures are generated and exchanged during the life cycle of large projects. The key to realising improved collaboration amongst the several disciplines involved is in the integration of such structures. Object-orientation has emerged as an appropriate approach for handling the complexity inherent in construction domains. This paper presents a pure object-oriented Integrated Building Project Model (IBPM). The model is a definition of objects and relationships that pertain to the three different construction-related disciplines of architecture, structural engineering and project management. It provides the basis by which software applications can share objects and a means of achieving integration. From the IBPM, the notion of Intelligent Object Classes (IOCs) is introduced, leading to the COllaborative Construction Integrated System (CO-CIS), the development of which is described in terms of its generic conceptual architecture. The exploitation of the architecture in a prototype implementation of the IBPM and IOCs is demonstrated by the generation of construction schedules through the integration of CAD and project management packages.

title	Climate and Building Design - Tradition, Research and Design Tools
source	Energy and Buildings. 1984. vol. 7: pp.55-69 : ill. tables. includes bibliography
summary	Important design parameters that influence the building thermal behavior and in particular natural cooling are discussed. Among these design parameters are: ventilation, evaporation, proper shading, orientation of the building and its proportions with respect to the orientation, the color of the building's envelope and its conductivity, the thermal mass of the building, night radiation to the sky and the stack effect. The latter is the katabatic and anabatic cooling. Different design tools aimed at the study of the influence of the climatological parameters on the form andÔ h)000*°° ÔŒ characteristics of buildings were developed in recent years. These tools help architects in designing houses with improved indoor thermal conditions without mechanical means, or with minimum energy consumptions. Several design tools, as well as design considerations and traditional constructions, are presented

title	La perception de l’espace urbain par la réalité virtuelle; Perception of urban space through virtual reality
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 533- 546
summary	Urban environment is a “sensible” space; it can manifest itself to our senses through the process of perception. The comprehension of the relation between man and his environment requires a study of spatial perception and its modes of interpretation. This paper proposes to study the perception by using the Virtual Reality (VR) technologies as a tool of qualitative analysis. The study presents an exploratory analysis of visual perception in a real urban path and its virtual modeling. It shows the potentials of virtual environments in the qualitative assessment of urban spaces.

title	Lighting in real and pictorial spaces: a computational framework to investigate the scene-based lighting distributions and their impact on depth perception
doi	https://doi.org/10.52842/conf.caadria.2010.501
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 501-510
summary	Architects often use two-dimensional media to represent, visualise, and study the three-dimensional qualities of un-built spaces. Knowledge of pictorial cues is a powerful design tool that can be used to enhance the spatial qualities of built environments. This paper draws from the recent developments in computer graphics (physically based renderings and perceptually based tone mapping techniques) and demonstrates the utilisation of a computational framework to generate pictorial spaces that can mimic perceptual reality. Computer simulation and psychophysical research methodologies are employed to examine the relationship between the lighting patterns introduced by architectural configurations and their impacts on depth perception. The research demonstrates that physically and perceptually based renderings can be used to study depth perception; and luminance contrast in an architectural scene is an effective pictorial cue that increases the perceived spatial depth.

title	Binocular Disparity and Depth Cue of Luminance Contrast

summary	Luminance contrast has been identified as an effective depth cue through perceptual studies using digital images generated by the integrated technologies of physically based lighting simulation and perceptually based tone mapping. However, the prior established framework utilizes a single camera viewpoint, failing to address the binocular vision of the human visual system. In this study, the computational framework is extended to incorporate 3-dimensional (3D) stereo display technology. Psychophysical experiments were conducted to investigate the depth effect of luminance contrast on the experimental scenes presented on conventional and stereo displays. The objective of this study was twofold: first, to investigate the effect of luminance contrast on depth perception, considering binocular vision; second, to further advance the visual realism of the computer-generated environment to reflect the perceptual reality of static pictorial and binocular disparity cues.

title	Cooperative work environment using virtual workspace
source	Proceedings of the Conference on Computer-Supported Cooperative Work: 226-232. New York: The Association for Computing Machinery
summary	A virtual environment, which is created by computer graphics and an appropriate user interface, can be used in many application fields, such as teleopetution, telecommunication and real time simulation. Furthermore, if this environment could be shared by multiple users, there would be more potential applications. Discussed in this paper is a case study of building a prototype of a cooperative work environment using a virtual environment, where more than two people can solve problemscooperatively, including design strategies and implementirig issues. An environment where two operators can directly grasp, move or release stereoscopic computer graphics images by hand is implemented. The system is built by combining head position tracking stereoscopic displays, hand gesture input devices and graphics workstations. Our design goal is to utilize this type of interface for a future teleconferencing system. In order to provide good interactivity for users, we discuss potential bottlenecks and their solutions. The system allows two users to share a virtual environment and to organize 3-D objects cooperatively.

title	Enumeration of Floor Plans Based on a Zero-Suppressed Binary Decision Diagram
source	International Journal of Architectural Computing vol. 13 - no. 1, 25–44
summary	This paper presents novel algorithms for enumerating architectural floor plans. The enumeration approach attempts to generate all feasible solutions that satisfy given constraints. Therefore, such a method might usefully reveal the potential diversity of Open Building floor plans. However, combinatorial enumeration solutions easily explode even for small problem sizes. We represent a space by a set of cells and organize some cells into polyomino-like configurations. We then enumerate all cell combinations that can be tiled in the given space using an efficient search algorithm for combinatorial problems. We also propose queries for extracting specific floor plans that satisfy additional constraints from all enumerated floor plans without re-enumeration. Our approach solves a 56-cell configuration space within a realistic timeframe.

summary	Open Building (Habraken, 1972) has been the focus of attention due to growing interest in the sustainable society. For Open Building, it is important to preserve the diversity of feasible floor plans in order to adapt to various lifestyles of residents. Capacity analysis is a method for evaluating the potential diversity. We propose a novel method that evaluates the potential diversity of floor plans by enumerating all feasible floor plans satisfying given constraints based on zero-suppressed binary decision diagram (ZDD) (Minato, 1993).

summary	This article explores possibilities of using fuzzy models as a new research tool in the history of architecture. Namely, Adolf Loos’s villas are studied using these models. Fuzzy expert models will be used to analyze the principles of Adolf Loos’s work. Rules applied by A. Loos in villa design will be expressed in the form of fuzzy rule bases. The formulation of rules will result from the analysis of individual villa designs and will be based on theoretical concepts pertaining to Loos’s work -- in particular, on his designing process drawing on the concept of a Raumplan. Further, the concepts of the theory of architecture, related to a general procedure of construction design, will be utilized. The article also gives examples how to employ fuzzy sets in describing a building and its characteristics.

summary	We live in an era of rapid change moving towards the information/knowledge/network society. eCity, eRegion, eCountry, eEuropeand the like are targets of many authorities round the world. One of the driving forces of this development is the new information andcommunication technology, ICT. This technology has developed rapidly during the last 20 years and the pace of development of newtools and applications is intense.The microprocessor, personal computer, mobile phone, e-mail, Internet, WWW and a number of software are good examples of ICT.The use of these tools is growing continuously and rapidly. The productivity of industries and effectiveness of services haveincreased. Civil society has found new ways of networking. Individuals have easy access to information around the world. Mobileand wireless communication is becoming commonplace.One aspect of ICT has been rarely discussed and that is: will ICT affect spatial development. During the agrarian era rural areas werethe focus of life, during the industrial era urbanisation took place. Railways and roads shaped spatial structures. Moderntelecommunications can be seen not only as a new way to behave but also as new kind of traffic. New ICT is not limited by location;it affects place and distance as the determinants of location. Thus it can be predicted that ICT as an essential element of informationsociety will reshape in the long run current regional, urban and rural structures and create new spatial forms for urban and rural life.Although there is still only little empirical evidence about n_w spatial development tendencies, a number of scientists have describedthese changes and illustrated what could happen. Land use planners should be aware of these development tendencies and beprepared for the new challenges they are facing.
