title The Incorporation of Construction History into Architectural History: The HISTCON Interactive Computer Program
source Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 235-243

summary Current teaching methods for architectural history seldom embrace building technology as an essential component of study. Accepting the premise that architectural history is a fundamental component to the overall architectural learning environment, it is argued that the study of construction history will further enhance student knowledge. This hypothesis created an opportunity to investigate how the study of construction history could be incorporated to strengthen present teaching methods. Strategies for teaching architectural history were analyzed with the determination that an incorporation of educational instructional design applications using object-oriented programming and hypermedia provided the optimal solution. This evaluation led to the development of the HISTCON interactive, multimedia educational computer program. Used initially to teach 19th Century iron and steel construction history, the composition of the program provides the mechanism to test the significance of construction history in the study of architectural history. Future development of the program will provide a method to illustrate construction history throughout the history of architecture. The study of architectural history, using a construction oriented methodology, is shown to be positively correlated to increased understanding of architectural components relevant to architectural history and building construction.

title Impact-Analysis of Urban Design Realtime impact-analysis models for urban designers
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary The past five years Prof Dr Jr T.M. de Jong, professor in environmental planning and sustainability at the Technical University of Delft, has developed a theoretical foundation for the analysis of urban design on the ecological, technical, economical, cultural and political impacts of morphologic interventions on different levels of scale. From september 1994 Jr AJ. Boelen (Urban Design Scientist and Knowledge Engineer) started a research project at the same university to further explore the possibilities of these theories and to develop impact evaluation models for urban design and development with the theoretical work of De Jong as a starting point. The paper discusses the development of a design and decision support system based on these theories. For the development of this system, techniques like object-orientation, genetic algorithms and knowledge engineering are used. The user interface, the relation between the real world, paper maps and virtual maps and the presentation of design-interventions and impacts caused by the interventions are important issues. The development-process is an interactive step by step process. It consists of the making of a prototype of the system, testing the theory and hypothe-sisses the system is based on, by applying tests end adjusting the theory and hypothesisses where needed. Eventually the system must be able to act as an integrator of many different models already developed or still to be developed. The structure of the system will allow easy future expansion and adjustment to changing insights. The logic used to develop the basic theory on which this system is founded makes it possible to even introduce and maintain rather subjective aspects like quality or appraisal as impacts that can be evaluated. In a previously developed system "Momentum" this was proved to work effectively for the national level. In this project we will - amongst other things - try to prove the effectiveness of impact-evaluation for other levels of scale.

title A Virtual Reality Design Environment with Intelligent Objects and Autonomous Agents
source H.J.P. Timmermans (ed.), Design and Decision Support Systems in Architecture and Urban Planning Conference, Vol. 1: Architecture Proceedings, pp. 132-142
summary New technological achievements and research results allow for the creation of innovative design tools for architects, that do not originate from paper-based paradigms but instead make optimised use of the present technology and programming concepts. The core of our system is comprised of an intuitive interactive modelling tool. It runs in a virtual reality set-up, where the user can use 3D glasses to experience rooms and 3D input devices to model in three dimensions. The interface is free from widget-like buttons or menus, so that the user is undisturbed when moving into the virtual world of the design. The system can also run in a distributed fashion, so that a number of users can look at and modify the same design. The 3D model can be generated in a sketch-like fashion using solids and voids, void modelling turns out to be very valuable for architectural design. The objects in this system can contain forms of intelligence to produce such behaviour as: falling because of gravity, collision avoidance, and autonomous motion. Interactive behaviour can also be assigned to the objects. Autonomous Agents are added to the system to enhance the designer support. These are agents that enhance the virtual environment, agents that take over tasks, and agents that help to test the design. The system shows new interface and interaction approaches that support the architectural design process intelligently.

title Re-Place-ing Space: The Roles of Place and Space in Collaborative Systems Learning from Space and Place
source Proceedings of ACM CSCW'96 Conferenc on Computer-Supported Cooperative Work 1996 p.10
summary Many collaborative and communicative environments use notions of "space" and spatial organisation to facilitate and structure interaction. We argue that a focus on spatial models is misplaced. Drawing on understandings from architecture and urban design, as well as from our own research findings, we highlight the critical distinction between "space" and "place". While designers use spatial models to support interaction, we show how it is actually a notion of "place" which frames interactive behaviour. This leads us to re-evaluate spatial systems, and discuss how "place", rather than "space", can support CSCW design.

source Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 253-262

summary The teaching of structures and its integration with design teaching has been seen as one of the major problems in design education in schools of architecture world-wide. A number of suggestions have been put forward to improve the quality of teaching in structures in architecture. These include the production of computer based learning materials, and the use of the computer as a ‘substitute’ tutor.

This paper reports on a SHEFC funded project jointly carried out by the Department of Civil Engineering, University of Paisley, the Mackintosh School of Architecture, and Lamp Software. The project aims to build a computer-assisted learning package on the response of structures to load. The software will be used as an interactive teaching tool for both architectural and engineering students.

The package has three levels: Beginners (Level 1), Intermediate (Level 2) and Advanced (Level 3). The first two levels have been completed after continuous feedback from both institutions. Level 1 is geared towards architectural and engineering students to help them understand structural behaviour of building components, such as deflection. Level 2 is a graphical editor that enables students to draw precisely the structure of their designs, investigate the deflection of structural members and identify areas of tension and compression. Level 3 is a design tool aimed at architectural and civil engineering students where they can design and analyse realistic structures by choosing structural members from a library, and specify materials and multiple loads.

Prior to its final release, the software package was appraised by students from both institutions. Analysis of results from questionnaires revealed that students expressed a great deal of 'satisfaction' with many of its teaching and learning attributes. The outcome of this project will promote and enhance students’ understanding of the response of structures to load; it will also help students grasp the impact of varying building materials and cross sectional properties on the structural form.

title Integrated Energy Modeling for Computational Building Design Assistance
source Carnegie Mellon University, Department of Architecture
summary Insights into the importance of energy modeling in building design have not yet resulted in the sufficient and systematic use of modeling tools in practice. In recent years, there has been considerable discussion on the limitations of simulation tools, and there is a noteworthy consensus as to the nature of the contributing factors (material and time implications, problematic user-interfaces, inefficient data communication structures, poor integration with CAD systems, absence of 'active' design support). This thesis deals with three research questions that are especially pertinent to the quest for active, multi-aspect design and simulation environments: (1) The appropriateness and feasibility of a methodologically consistent performance modeling approach through the entire design process. (2) Strategies for a structurally 'seamless' containment of performance simulation within a computational design environment. (3) Technologies to facilitate dynamic and interactive performance-to-design mapping. At a paradigmatic level, this thesis critically examines the existing responses to each of these questions, and proposes alternative computational frameworks and technologies to overcome some of the system-immanent ('endogenous') limitations of the existing approaches. At an operational level, this thesis demonstrates the proposed solutions by implementing an active thermal simulation module (NOD

summary Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.

summary This paper describes the integration of machine intelligence into an immersive architectural sculpture that interacts dynamically with users and the environment. The system is conceived to function as an architectural envelope that might transfer air using a distributed array of components. The sculpture includes a large array of interconnected miniature structural and kinetic elements, each with local sensing, actuation, and machine intelligence. We demonstrate a model in which these autonomous, interconnected agents develop cooperative behaviour to maximize airflow. Agents have access to sensory data about their local environment and ‘learn’ to move air through the working of a genetic algorithm. Introducing distributed and responsive machine intelligence builds on work done on evolving embodied intelligence (Floreano et al. 2004) and architectural ‘geotextile’ sculptures by Philip Beesley and collaborators (Beesley et al. 1996-2006). The paper contributes to the general field of interactive art by demonstrating an application of machine intelligence as a design method. The objective is the development of coherent distributed kinetic building envelopes with environmental control functions. A cultural context is included, discussing dynamic paradigms in responsive architecture.

source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary Software systems for educational purposes have been developed and used in many application areas. In this paper we will describe a development in the field of building science. ClAD is a teachware system directed to be used in the education of students of architecture as well as a tool that gives a survey to architects and engineers in the practice. In the first place it provides information about the use of computer science technologies in the building design process. Furthermore, information about the architectural design process itself is included. Based on an analysis of general requirements and specific demands of the application field we describe our solution concept. Very important conclusions are that the system has to integrate the use of all media which are usually used by architects by offering a flexible and well-designed user interface and allowing a high degree of interactive work. After covering the development process as a combination of top down and bottom up strategies we describe the overall structure of ClAD as a modular system which can be extended and updated easily. Finally, we give an overview about some parts of the system to demonstrate the implementation of the concepts mentioned above.

summary As the title suggests, this paper makes an attempt to provide a factual analysis and synthesis of the activities that the Tex-Mex Virtual Design Studio, and later the Las Americas Virtual Design Studio, have been implementing since September of 1996, The objective of this attempt is to provide a framework for the formulation of a new conceptual and instrumental profile for future implementations of our virtual design studios. With such a purpose the paper outlines the importance of virtual design studios in the framework of opening design education to distance education methodologies and argues in favor of their further utilization for addressing issues of globalization in architecture and design education. This argument is followed by a quick description of current practices within the Las Americas Virtual Design Studio and sets the stage for a detailed description of how multi-user interactive environments may further support interaction within virtual design studios.

source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary This paper analyzes the use of a 31) hypermedia system in architectural presentation. It first reviews the current process of using computer animation in architectural presentation and identifies problems in the current process. The research assumes that a new approach using the hyper-model environment and animation together would provide a better environment for presenting architectural animation. An interactive animation viewer is designed and developed using the new approach. A sample architectural animation is presented using a tape-recorded animation player, a normal animation player, the interactive animation viewer, and a real-time animation player. The analysis of the result is made by a comparison in terms of image quality, speed, user interactions, object hyperlinkage, scene complexity, and information transmission on using different systems in presenting the same material. A conclusion is drawn to show the advantages of using the new approach. Limitations on using the new approach are identified too.

summary The rapid speed of computer development brings new technologies, and these advances require innovative investigations to apply them optimally in the field of architecture. Burkett (1984) demonstrated that computer graphics can ‘provide an excellent opportunity for exploring solar issues in building redesign’. With one of the latest computer technologies, the "hyper-model” environment, this research investigates how to environment can become an aid in the design and decision support area. The research first reviews the communication between the architect and the client as described by Salisbury (1990). The review indicates that an interactive 3D hypermedia paradigm, with quick response, fast data manipulation and 3D visualization, offers a better communication media between the architect and the client. This research applies the "hyper-model” environment to design and develop a new methodology in collecting, analyzing, and presenting solar data. It also endeavors to show the possibilities of using the environment in design process.

title Put: Language-Based Interactive Manipulation of Objects
source IEEE Computer Graphics and Applications
summary Describing a scene to a computer is an inherent task of computer graphics applications. Modeled scenes are typically built with direct placement techniques or specialized scripting languages. The scene description task could be greatly eased if natural language were an interactive control option. However, natural language understanding is notoriously difficult for computers. This difficulty is exacerbated in the case of computer graphics by the need for geometric output, not just "conceptual understanding" or high-level inferencing. General text-understanding techniques have not been successfully applied to scene generation. Typically, a few task-specific commands, such as "walk," are implemented as an ad-hoc collection of procedures. Our approach aims to separate the expressive power of fundamental natural concepts from the difficult task of text understanding. We are developing a 3D object placement system based on a combination of natural commands and interactive techniques. Guided by research in cognitive linguistics, we use basic spatial relationships--such as in, on, and at--and fundamental scene parameters--such as viewer location and object dimensionality--to identify regions of placement for objects in a scene. These natural commands can be used to quickly prototype a complex scene and constrain object placement.

title Osmose: Towards Broadening the Aesthetics of Virtual Reality
source ACM Computer Graphics: Virtual Reality Volume 30, Number 4
summary Osmose is an immersive virtual environment, produced by Softimage in 1994/95. One of the primary goals of Osmose was to push the expressive capabilities of existing 3D tools, to demonstrate that an alternative aesthetic and interactive sensibility is possible for real-time, interactive, 3D computer graphics. Osmose was created under the direction of Char Davies, the Director of Visual Research at Softimage. A former painter, as well as a creator of 3D computer graphic stills, Davies has a particular artistic vision which has driven the project. Davies has been striving for years to represent space as a luminous enveloping medium. This has led her from painting to 3D computer graphics, and finally into creating immersive virtual spaces. One of Davies' intentions for Osmose was to create a space that is "psychically innovating," one in which, to quote Bachelard, participants do not change "place," but change their own nature. Osmose was therefore designed to explore the potential of immersive virtual space to allow participants to shed their habitual ways of looking at (and behaving in) the world. By doing this, we hoped they would then emerge from the virtual world to experience the real world in a fresh way, reawakening a fundamental sense of their own "being-in-the-world." We hoped that this could be accomplished through the visual, aural and interactive aesthetic of the work.

title Novel Affordances of Computation to the Design Process of Kinetic Structures
source Massachusetts Institute of Technology, Cambridge, MA
summary This paper is a discourse into the relationship between the process, computational tools and the role which symbolic structure can play in both. I argue the relationship of the process and tools is dialectic, whereby the tools we utilize in design develop new heuristics, the methodologies in turn, if reflectively understood, can be more aptly facilitated through the development of novel tools. The tools and the process then evolve together. A theory is laid out exploring the human visual information processing systems pertinence to the limitations in mental three-dimensional imaging and transformation operations as relevant to the operations of drawing and mental visualization within the architectural design processes, substantiating the designers necessity to draw (by traditional means, but more importantly here, through the inclusive integration of CAD within the process). The necessity to draw is explored as a representational process to the visual system as predicated upon the existence of a structured internal library of diagram-like representations in our heads. I argue that the ways we utilize such idiosyncratic libraries is predicated upon the ways in which we go about structuring the perceived experienced world around us into symbol systems. And finally, the ways we utilize our reflective understanding of the heuristic transformations of these symbols within the design process in the context of a CAD environment are explored as a means to an enhanced understanding of that which is being designed and consequently as a vehicle for the development of future CAD systems to better facilitate such methodologies of designing. A personal design process of several kinetic structures is carried out in order to arrive at a localized process analysis within computer-aided design environment. Through an interactive, reflective process analysis, conclusions are drawn as to the affordances and limitations of such tools as suggestive of the operations a CAD environment might perform so as to better foster future methodologies of designing. The design experiments are utilized as a vehicle to understand the process. Specifically three kinetic projects are exploited for the prototypical operations they display. When difficulties or mental limitations are encountered with the operations, specific tools are developed to facilitate the limitation or to overcome the problem.

title Spatial Knowledge Acquisition from Maps and Virtual Environments in Complex Architectural Space
source Proc. 16 th Applied Behavioral Sciences Symposium, 22-23 April, U.S. Airforce Academy, Colorado Springs, CO., 1996, 6-10
summary It has often been suggested that due to its inherent spatial nature, a virtual environment (VE) might be a powerful tool for spatial knowledge acquisition of a real environment, as opposed to the use of maps or some other two-dimensional, symbolic medium. While interesting from a psychological point of view, a study of the use of a VE in lieu of a map seems nonsensical from a practical point of view. Why would the use of a VE preclude the use of a map? The more interesting investigation would be of the value added of the VE when used with a map. If the VE could be shown to substantially improve navigation performance, then there might be a case for its use as a training tool. If not, then we have to assume that maps continue to be the best spatial knowledge acquisition tool available. An experiment was conducted at the Naval Postgraduate School to determine if the use of an interactive, three-dimensional virtual environment would enhance spatial knowledge acquisition of a complex architectural space when used in conjunction with floor plan diagrams. There has been significant interest in this research area of late. Witmer, Bailey, and Knerr (1995) showed that a VE was useful in acquiring route knowledge of a complex building. Route knowledge is defined as the procedural knowledge required to successfully traverse paths between distant locations (Golledge, 1991). Configurational (or survey) knowledge is the highest level of spatial knowledge and represents a map-like internal encoding of the environment (Thorndyke, 1980). The Witmer study could not confirm if configurational knowledge was being acquired. Also, no comparison was made to a map-only condition, which we felt is the most obvious alternative. Comparisons were made only to a real world condition and a symbolic condition where the route is presented verbally.

summary Interfaces for conceptual and creative design should recognize and interpret drawings. They should also capture users' intended ambiguity, vagueness, and imprecision and convey these qualities visually and through interactive behavior. Freehand drawing can provide this information and it is a natural input mode for design. We describe a pen-based interface that acquires information about ambiguity and precision from freehand input, represents it internally, and echoes it to users visually and through constraint based edit behavior.

summary The course on CAAD at the KU Leuven is part of the course on design methodology and theory from which it is the most recent and natural extension. Attached to this course a series of assignments has been developed which bring the students in 45 hours to a non-trivial level of acquaintance with CAAD. Our assignments are primarily directed towards practice. They are built on top of AutoCAD to which we have added in-house developments in order to focus on specific pedagogical goals within a very limited time. After a general introduction on Windows (file management) and AutoCAD (basics) students make the following assignments (main pedagogical goals in between brackets). colophon (working with blocks), detail (2D-drawing, hatching, editing), facade design using a built-in system of proportion (slides, scriptfile), extraction (linking alphanumerical and graphical entities), container (level of detail, icon menus, viewports), surface modelling (modelling 3D-objects with surfaces), fractal tree (recursion in Autolisp), solid modelling (Leicester engineering building), lighting (integration of drawing and computation of illumination levels), pressure lines in an arc (interactive design of an arc), demos. The paper presents and comments these assignments and shows results from the last 2 years.
