summary	Web sites with animations, panoramic images, sound, and virtual reality can provide a strong sense of place, richer than text and photographs and more interactive than cinema. Constructing these sites demands a great deal of visual and textual information, which must be organized, integrated, and coded for delivery. Existing authoring packages are general-purpose, not specifically for architectural applications, and require technical sophistication. In our process for building Place Based Web Resources (PBWRs), after assembling photographic, drawing, text, and audio resources, the author follows a straightforward series of steps. The Hagia Sophia Web Resource resulted from this process; it includes panoramic pictures, photographs and interpretive text about the building and a VRML model.

title	Using Virtual Worlds as Collaborative Environments for Innovation and Design: Lessons Learned and Observations from Case Studies in Architectural Projects
doi	https://doi.org/10.52842/conf.ecaade.2009.523
source	Computation: The New Realm of Architectural Design [27th eCAADe Conference Proceedings / ISBN 978-0-9541183-8-9] Istanbul (Turkey) 16-19 September 2009, pp. 523-532
summary	In this paper we discuss observations and lessons learned in conducting architectural design projects in virtual worlds. By integrating a community of users in virtual worlds into a collaborative architectural design process, organisations can tap the community’s creativity and intelligence through immersive technology. The paper provides an overview of the latest advances of information and communication technologies in immersive virtual environments and discusses some of the observations and lessons learned which should be taken into account in developing collaboration models for such activities. Here we propose four modes of collaboration, based on the choices for degree of openness and governance structure, which are illustrated by four case studies.

title	How Complete are Knowledge Representation Systems?
source	IEEE Computer. IEEE computer society, October, 1983. vol. 16: pp. 114-118. includes bibliography
summary	Prolog, the most feasible of the first-order logic systems, has intriguing analogies with Absys, short for Aberdeen System, an assertative programming system developed in 1968. In this article, the issue of incompleteness is explored by comparing aspects of the two systems, and the incompleteness resulting from any serious use of Prolog as a vehicle for a knowledge-based system is addressed

title	An information engineering approach to modelling building design
source	Automation in Construction 4 (1) (1995) pp. 5-15
summary	This paper highlights potential problems in the construction industry concerning the large quantities of information produced and the lack of an adequate information structure within which to coordinate this information. The Information Engineering Method (IEM) and Information Engineering Facility (IEF) CASE tool are described and put forward as a means of establishing an information structure at a strategic level thus providing a framework for the implementation of lower level applications systems. The paper describes how the ICON (Integration/Information for Construction) project at Salford University is establishing and modelling the information requirements for the construction industry at the strategic level. The IEM and IEF are demonstrated using activity, data and interaction models with particular attention being paid to the function of building design within the broader context of design, procurement and the management of construction. Implications for future practice are also discussed.

summary	Parametric modeling systems are widely used in architectural design. Their use for designing complex built environments raises important practical challenges when composed by multiple people with diverse interests and using mostly unverified computational modules. Through a case study, we investigate possible concerns identifiable from a real-world collaborative design setting and how such concerns can be revealed through interactive data visualizations of parametric models. We then present our approach for resolving these concerns using a design analytic workflow for examine their reliability and validity. We summarize the lessons learnt from the case study, such as the importance of an abundance of test cases, reproducible design instances, accessing and interacting with data during all phases of design, and seeking high cohesion and decoupling between design geometry and evaluation components. We suggest a systematic integration of design modeling and analytics for enhancing a reliable design decision-making.

title	Informing User-Centred Approaches to Augmented Custom Manufacturing Practices

source	Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 353–362
summary	This practice-based research presents insights into the potential and challenges for augmented and mixed reality (AR/MR) technology to enhance Australian small-to-medium (SME) custom manufacturers’ agility to overcome existing Industry 4.0 (I4.0) workforce productivity and efficiency challenges. Moreover, it seeks to understand the technology’s ability to support custom manufacturers and the architectural, engineering and construction (AEC) sector transition to a more human-centric Industry 5.0 (I5.0) model, whereby the well-being of the fabricator is placed back at the centre of manufacturing processes. This qualitative study draws on interviews with eleven Australian custom manufacturing industry professionals to inform pertinent themes around fabricators’ current use and perceptions of mixed reality technology. Results indicate benefits for fabricators in reducing 2D drawing and task-related ambiguities in fabrication and assembly practices and reveal factors surrounding underutilisation. Synthesising insights and reflecting on Teixeira et al., (2021)’s XR-PACT framework, key research areas are identified for future AR/MR development centred on fabrication users’ distinct needs to improve accessibility, empower fabricators and ultimately assist the competitiveness of custom manufacturers and the AEC sector.

title	Obstructed Magic: On the Myths of Observing Designing and of Sharing Design Observations
doi	https://doi.org/10.52842/conf.caadria.2008.278
source	CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 278-284
summary	Much design research, including much research in the computer-aided architectural design field, is based on the assumption that the process of designing is observable and that what happens in designing can be known, explicitly described and shared. In this paper I examine this assumption from my subjective viewpoint and conclude that designing occurs behind a blind spot. It can be concluded that existing design process models used in the “science of design” are based on invention rather than on empirical evidence, which in turn suggests that science should be studied as a form of design instead of studying designing scientifically.

source	14 p. : ill. Pittsburgh: Design Research Center, CMU, April, 1982. include bibliography: p. 12
summary	Finite element methods are introduced for the approximate solution of periodic acoustic problems. A least squares technique is used for those problems which are governed by a first order system of partial differential equations while for second order equations, a Galerkin/multigrid technique is employed. In both cases, the solution process for the algebraic system resulting from discretization is iterative in character

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 258-269.
summary	This study investigates and demonstrates a method and process for the development of thermal clay tiles, with a focus on cooling properties. The study is based on a craft-com- putation approach, combining clay-ceramic manual techniques with parametric design-simulation methods, using thermal flux and computer fluid dynamic simulation procedures. From the experimental studies, novel clay-glaze prototypes are proposed and tested for temperature and air properties, which effectively impact building thermal environments and energy consumption in a warming world. The studies find that thermal performances can be significantly steered by the specific material-form articulation presented, that the suggested modular assembly and simple fabrication procedure support a feasible integration, and that the proposed tiles illustrate a rich, articulated material-form characterization that presents both qualitative and quan- titative perspectives for further studies

summary	This paper describes the use of parametric methods in generating conceptual designs of high-rise buildings. We first assess current conceptual design practice at a leading AE firm and illustrate the challenge of satisfying a complex set of requirements with the tools currently used by the AEC industry. Few design options are generally developed and analyzed; better design solutions are most likely being overlooked. Parametric tools can potentially help address this problem by allowing designers to formalize and generate solution spaces that can be explored. But few case studies exist to document the construction and impact of these models. We present such a case study. We describe the variables, constraints, components, and rules in the model. We discuss the costs and benefits, and conclude with recommendations for expanding the use of parametric methods.

title	A Review of Object Oriented CAD Potential for Building Information Modeling and Life Cycle Management
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	In many countries, the Architecture/Engineering/Consulting (AEC) industry is characterised by poor performance reflected in project delays and cost overruns. A contributor to the problem is the traditional approach to handling building information and its communication in life cycle management (LCM). Recent developments in Object Oriented Computer Aided Architectural Design (OO CAD) have provided the opportunity for improving building information modelling and its communication for more effective LCM. The aim of the paper is to review the potentials of OO CAD for building information modelling (BIM) and LCM. The paper reviews building information in the life cycle process, identifying the various actors and activities and the need for communication and information flow to support life cycle management. The paper also reviews the concept of OO CAD, highlighting its potential to improve building information and its flow and communication in life cycle management. The paper then goes on to review the potentials and limitations of OO CAD implementation in the AEC industry. The paper concludes by pointing out that the widespread adoption of OO CAD and the anticipated associated improvement in life cycle management will only be encouraged when the building industry is able to agree on a widely acceptable, interoperable standard for encoding building objects.

title	Fast Spheres, Shadows, Textures, Transparencies, and Image Enhancements in Pixel-Planes
source	SIGGRAPH '85 Conference Proceedings. July, 1985. 1985. vol. 19 ; no. 3: pp. 111-120 : ill. includes bibliography
summary	Pixel-planes is a logic-enhanced memory system for raster graphics and imaging. Although each pixel-memory is enhanced with a one-bit ALU, the system's real power comes from a tree of one-bit address that can evaluate linear expressions Ax + By + C for every pixel (x,y) simultaneously, as fast as the ALUs and the memory circuits can accept the results. The development of a variety of algorithms that exploit this fast linear expression evaluation capability has started. The paper reports some of those results. Illustrated in this paper is a sample image from a small working prototype of the Pixel- planes hardware and a variety of images from simulations of a full-scale system. Timing estimates indicate that 30,000 smooth shaded triangles can be generated per second, or 21, 000 smooth-shaded and shadowed triangles can be generated per second, or over 25,000 shaded spheres can be generated per second. Image-enhancement by adaptive histogram equalization can be performed within 4 seconds on a 512 x 512 image
