title	Shape recognition in three dimensions
source	Environment and Planning B: Planning and Design 19 : 585-603
summary	The subshape recognition problem for three-dimensional shapes under linear transformations is considered. The problem is analysed in a series of cases, some that provide a determinate number of solutions and others that have indeterminately many solutions. Procedures for its solution for general shapes are developed. Difficulties posed by strict adherence to rational transformations are examined. As a corollary, an outline of a procedure for determining the symmetries of a shape is presented. Subject

title	Spatial Grammars: Motivation, Comparison, and New Results
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 57-74
summary	The paper starts by giving a motivation for studying grammars in design and is based on considerations of style, discovery, and constructive techniques. This paper goes on to survey a variety of spatial grammar formalisms from an implementation standpoint. For each formalism, the salient computational issues pertaining to rule application are discussed. Two aspects of shape grammars are considered in detail: (a) the conditions for reversibility of shape rules, and (b) the recognition of planar shapes.

title	Modelling Design Descriptions
source	January, 1986. [5] p. : ill
summary	This paper reports some of the principles that underlie a modelling environment being developed at EdCAAD. It describes research that is part of a larger programme directed at computer-based systems that can accommodate the idiosyncratic nature of design practice, without prescriptions to the form or content of designs. That is, towards developing systems to assist in the design process by enabling designers -via conversations with the machine - to make 'reasonable' statements about design objects; to ask 'reasonable' questions about these objects; and to perform 'reasonable' tasks on these objects. Implicit in the authors' approach is the view that designing is an activity dependent on designers' perceptions of design tasks and their resolution. In the context of computer-aided design, this view of design demands that the crucial element in any machine environment lies in the ability of the machine to accept (partial) descriptions of design objects. Moreover, these descriptions can be manipulated according to some (perhaps unanticipated) criteria that the designer may wish to apply. The authors present a model for intentional descriptions of objects. That is, a description that can be structures so that it can be used to recognize objects and can be compared with other descriptions. Such a description of an object should be organized around entities with associated descriptions, it must be able to represent partial knowledge about an object, and it must accommodate multiple descriptors which can describe the object from different viewpoints. Last, but not least, these descriptions should possess a quality of 'truth' in that they reflect the (factual or otherwise) beliefs held by the designer. One way to treat these descriptions is to regard them as statements that belong to some logical framework

title	Performance Evaluation of 3D-Model CAAD Implementation in Dutch Architecture Firms
source	South Bank University [In cooperation with Hogeschool van Arnhem en Nijmegen - The Netherlands]
summary	The principal theme of this research is to provide information regarding the implementation of 3D Model CAAD, CAAD system which uses 3D Drawing Production Method (DPM) instead of 2D DPM This research is focused on its implementation in architecture firms and on justifies its performance and investment value. Principally there are two evaluations conducted in this research. First evaluation aimed to justify 3D-Model CAAD influence on design process and the second is investment evaluation which aimed to provide information for current and prospective user regarding their current and future investment on 3D-Model CAAD. The results of the evaluations are: 3D Model CAAD has improved performance through efficiency on time and cost of design process also improvement on design quality. However correlation between the use of 3D-Model C.4AD and better performance, while tested using Chi-Square Test, is not significantly. This fact indicates that there are some other strong factors to influence design performance. Second, 3D-Model CAAD, according the Importance-Performance Map is positioned at top right quadrant which categorised as 'keep the good work' which means it has good investment value.

title	Approaching Sentient Building Performance Simulation Systems
doi	https://doi.org/10.52842/conf.ecaade.2014.2.049
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 2, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 49-60
summary	Building designers make decisions in early design stages that have large impact on building performance, including those of energy-, daylight- and indoor environment performance. Building performance simulation (BPS) tools can support the designer, in making better decisions, by providing the performance consequences of design choices. However BPS tools often require deep technical knowledge and is too time consuming to use to effectively support the design exploration in the early design stages. To solve this challenge, the current paper proposes: Sentient building performance simulation systems, which combine one or more high precision BPS tools to provide near instantaneous performance feedback directly in the design tool. Sentient BPS systems are essentially combining: 1) design tools, 2) parametric tools, 3) BPS tools, 4) dynamic databases 5) interpolation techniques and 6) prediction techniques as a fast and valid simulation system for the early design stage.

title	Re-imagining The Urban Development of Western Sydney: The Case Study of Oran Park
doi	https://doi.org/10.52842/conf.caadria.2024.1.353
source	Nicole Gardner, Christiane M. Herr, Likai Wang, Hirano Toshiki, Sumbul Ahmad Khan (eds.), ACCELERATED DESIGN - Proceedings of the 29th CAADRIA Conference, Singapore, 20-26 April 2024, Volume 1, pp. 353–362
summary	This paper addresses the challenges of rapid urban expansion in Western Sydney, Australia, using the suburb of Oran Park as a case study. With the region's population projected to more than double by 2041, and an expected influx of an additional 400,000 people by 2030, there is a pressing need for sustainable and environmentally responsive urban development. Current approaches have prioritised space utilisation over environmental and social considerations, leading to homogeneity and poor urban quality. In response to these challenges, this study proposes a four-stage generative model for Oran Park, emphasising environmental restoration, agricultural integration, and housing diversification. This model aims to balance economic growth with environmental sustainability, contrasting with the density-focused development prevalent in the area. By implementing multi-objective optimisation, this research presents an algorithm-driven approach to urban planning, catering to the diverse needs of the expanding population.

title	Iris Diaphragm Mechanism Application for Daylighting Control
doi	https://doi.org/10.52842/conf.ecaade.2021.1.505
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 1, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 505-514
summary	Daylight is an important factor in interior design. The benefits can be seen in reduced need for heating and artificial lighting, while the caveats are visual hindrance, glare, thermal discomfort and increased energy for cooling. The industry standard way of controlling daylighting is with roller blinds, venetian blinds, curtains, static and automated façades which do not allow sufficient control over daylight. The aim of this paper is to explore the potential of using circular modules with the iris diaphragm mechanism as a system for controlling the daylight amount, similar to the approach used on Arab World Institute. Circular module that are proposed in the paper consists of an outer casing, inner rotational and stationary rings and blades. A parametric iris model is generated and optimized to conform to the criteria of having the smallest casing, thinnest blades and the least amount of blades to decrease fabrication and assembly time. The circular module is applied in three layouts on a rectangular opening to calculate the efficiency in daylighting control. Obtained results show significant increase in systems flexibility and performance compared to the closest implementation in the south façade of the Arab World Institute.

summary	This paper presents the experience of implementating GIS technologies at a county town urban planning department. The necessity to implement GIS technology is partly dictated by the requirements of the INSPIRE Directive. The discussed case provides valuable information about the problems and challenges that cities have in Poland, while performing their obligations under the directive. The process of preparing the necessary geographical database corresponding to existing planning documents raises many legal and technical problems. The presented case illustrates the whole process associated with the preparation of digitization and publication of urban plans. At the same time, it is worth to see the numerous benefits that the city obtains after publishing GIS data. Attention should also be paid to the further development of GIS and the chances of their use, especially in urban centers.

title	An intelligent and responsive architecture
source	Automation in Construction 6 (5-6) (1997) pp. 381-393
summary	Today's intelligent buildings are actually electronically enhanced buildings, the forerunners of a new architecture. They herald an impending paradigm shift in the world of architectural design. This shift will occur, in part, as a response to the need for healthy and sustaining buildings, the opportunities presented by innovations in science and technology, the demands of the new global economy, and the growing realization of the value of human capital by knowledge-based companies. The resulting architecture will be comprised of responsive environmental systems and will mark the emergence of a fully developed intelligent architectural form - the Knowledge Building.

title	Artificial Reality II
source	Reading, Massachusetts: Addison-Wesley Publishing. 2nd.ed.
summary	The focus of Myron Krueger in Artificial Reality II is the interaction between humans and machines, both in the immediate interface and the associated cultural relationships. He uses the concept of artificial reality as a medium of experience and as a tool to examine the relationships between people and machines. When he first coined the term in the mid-1970s, his 'goal was full-body participation in computer events that were so compelling that they would be accepted as real experience.' He wanted to create an artificial reality that would perceive human actions in a simulated world of sight, sounds, and other sensations and would make the experience of this illusion convincing. His focus was to create unencumbered, artificial realities where the humans could participate with their entire body without wearing any special instruments (be they sensors or displays) in an experience created by the computer. The environment could be controlled by preexisting programs, or could have operators intervene and use the computer to amplify their ability to interact with people. The intention was not to reproduce conventional reality but to create synthetic realities.

summary	This article describes how architects can use the strengths of an immersive or semi-immersive virtual environment to create a shared understanding about a design problem. Virtual environments can allow the strong shared understanding under particular circumstances within a collaborative design set-up. The authors will describe which particular factors of shared understanding could be supported within a virtual environment, and which kind of requirements this poses on the virtual environment itself, and the technology which generates the environment. Specifically focused is at how one can create a common understanding of the spatial construction and meaning of a preliminary design idea. Therefore, a major focus is at the transfer of spatial knowledge about architectural space.

title	Crystal Formations and Symmetry in the Search of Patterns in Architecture

summary	Nature is always full of patterns inspiring all the disciplines and especially architecture in many ways. Currently, with the advances in technology and growing interest towards nature-driven studies, retrieving information from nature has a new connotation in scales and dimensions including both living and non-living beings. In this study, it is aimed to explore the scales of nature from Nano to Macro and a holistic approach is embraced to cope with the complexity of nature and architecture. To understand these complexities, patterns in different forms and scales serve as valuable tools to decode and recode information from one domain to another through locating the order and how patterns exist in different and changing environments with respect to forces and the urge of the existence of the being.This research focuses on the behavior of crystal formation which can be observed both in biotic and abiotic nature to understand the order generating the patterns in nature and its adaptation into a different and changing environment. This information of crystallization has great potential for architecture in terms of spatial structures, new materials and introducing a novel lattice for freeform structures. In this study, the potentials, limits and possible contributions of crystal formation are stated for architecture in the search of symmetry and patterns.

summary	Nature provides a vast amount of information to be learnt in various scales with different level of complexities in architecture. Today, the increasing role of computational design and advents in new fabrication technologies enable architectural praxis to incorporate data coming from various disciplines in the design process. Among them, data coming from nature with its animate and inanimate parts are began to be revisited more than before via different approaches. In this study, information transfer from nature to architecture is described as a mapping process defined with different levels depending on the complexity of the information transfer process. Present study explains these levels and exemplifies through the study conducted in Nature-informed Computational Design course.

source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 2, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 207-215
summary	The paper presents an undergoing research that aims at developing a system, which will allow customer participation in a design of mass-customized houses. The system will allow customers to self-configure a house in a preferred way in relation to the site where it is going to be constructed and with a respect to the prescribed architectural rules. Introducing customer participation in the design process of mass-customized houses allows users to find out individual design goals transforming the design process from being ill-defined into goal-oriented. The proposed system for customer participation could become feasible alternative to the traditional process of provisioning affordable houses improving the living quality in these market areas where architectural knowledge is unaffordable and missing.

title	Rob-LCA - An assessment method to support environmental sensitive material selection in robotic fabrication
doi	https://doi.org/10.52842/conf.ecaade.2021.1.455
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 1, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 455-464
summary	Facing the current environmental crises, architecture must embrace sustainable modes of design and production. This requires the careful selection of the materials by assessing their lifecycle performance, which is not yet an easy and stable practice. In this context, this paper presents an assessment model called Rob-LCA to evaluate environmental-sensitive material selection for robotic fabrication. The model takes the data related to design and material as an input, it gives the Environmental Impact Indicator based on calculations. Then, designers evaluate and compare the fabrication processes, whether the environmental impact of the materials is satisfactory for the designed object. As a contribution, the proposed model complements information of the environmental impact of the A3, and A5 phases of the typical LCA method, adapting the customization and construction abilities of the robotic fabrication. In this study, the Rob-LCA was tested with the CorkCrete Arch prototype for a compound building system developed by Digital Fabrication Laboratory (DFL). By considering its multi-material panel, the production life cycles of cork and expanded polystyrene were assessed. Initial findings of the test of the model show that the proposed model might open a new path for sustainable manufacturing. This work presents thus a contribution to frame and align the use of digital design and fabrication processes with the current demands for environmental sustainability.

title	Digital Fabrication Methods of Composite Architectural Panels for Complex Shaped Buildings
doi	https://doi.org/10.52842/conf.caadria.2015.703
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 703-712
summary	Composite materials have been explored in architecture for their high performance characteristics that allow customization of functional properties of lightness, strength, stiffness and fracture toughness. Particularly, engineering advancements and better understanding of fiber composites have resulted in growing applications for architectural structures and envelopes. As most developments started outside the realm of architecture such as automobile and aeronautical industries, there is need to advance knowledge in architectural design to take advantage of this new technology. In this paper, the authors introduce preliminary results of new digitally driven fabrication methods for fiber-reinforced composite sandwich panels for complex shaped buildings. This research examined the material properties, manufacturing methods and fabrication techniques needed to develop a proof of concept system using off-the-shelf production technology that ultimately can be packaged into a containerized facility for on-site panel production. Experiments focused on developing a digitally controlled deformable mold to create composite relief structures for highly customized geometrical façade components. Research findings of production materials, methods, assembly techniques, are discussed to offer insights into novel opportunities for architectural composite panel fabrication and commercialization.
