title	A Real Time 3D Environment for Collaborative Design
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 203-212
summary	By setting up collaborative design processes in architecture it is possible to considerably improve the integration of customer needs and ideas into the programming phase of a building project. Our design process includes active collaboration between customers, users and other stakeholders as well as the use of virtual environments in conceptual design. The output from the process is treated as visualised input to the architectural programming. The work presented focuses on developing digital tools to support this collaborative design dialogue. We have developed an extremely “easy to use” digital modelling tool called “ForeSite Designer”. The tool enables the users to build layouts of prefabricated components on a building site in 2D. This 2D layout can then instantly be exported to a lit-up real time 3D environment in the computer game “Half-Life.” ForeSite Designer has been used in a several design events with different settings. This paper presents the tool and one project where it was utilized. The results show that ForeSite Designer can promote dialogue and collaborative design work among the participants. We have also found that it is important how the virtual environment and its components are visually designed in order to support the dialogue and collaborative design work.

summary	This paper describes the concept and the current state of development of a new laboratory for digital experimentation in architectural education and research. The novel forms of collaboration and learning for which it is intended and the quick pace of innovation in digital technology on which it depends both require an appropriately flexible spatial and technological framework. And it requires a particular mindset. The no_LAb__in_feld is not just another laboratory. It is a place, a community, a high-tech construction site, a permanent work in progress. It is the prototype of a next generation design studio.

title	Interactive Tools for Collaborative Architectural Design
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	Today’s rapidly changing society is continuously developing towards an increased demand for multistakeholder knowledge and influence in the architectural planning and design process. Accordingly, we are working with developing and setting up a partner engaged collaborative design process. It includes active collaboration between users, external partners and designers, and visualizations in conceptual design and scenario building. My research is focusing on integrating visualization technology in theseprocesses by application of digital tools. We have developed a working prototype for an interactive design tool. The prototype is an extremely “easy to use” digital modeling tool called “ForeSite Designer.” With this tool one builds one’s own spatial environment with elements on a 2D surface.With one command the 2D layout is exported to a lit-up 3D/Virtual Reality world in the computer game “Half-Life”. ForeSite Designer has lately been used in a series of workshops together with external users. In these processes ForeSite Designer has played a crucial role as an arena of building spatially arranged concepts of future environments. The results show that it works, and, importantly, promotes a collaborative engagement among the users.

title	An Accelerated Rendering Algorithm for Stereoscopic Display
doi	https://doi.org/10.52842/conf.caadria.1996.053
source	CAADRIA ‘96 [Proceedings of The First Conference on Computer Aided Architectural Design Research in Asia / ISBN 9627-75-703-9] Hong Kong (Hong Kong) 25-27 April 1996, pp. 53-61
summary	With the development of the scientific visualization and the virtual environment techniques, stereo viewing systems have not been used extensively. In this paper, we present an accelerated rendering algorithm for stereoscopic display. As the difference between the left view and the right view is slight, we generate the right view by a transformation of the left view conforming to the stereo disparity. The problem of visibility change of a few polygons during the transformation is discussed and an efficient algorithm is developed for filling the holes that may arise in the right view after the transformation. This method makes fully use of the coherence between the left view and the right view. Experiments prove its efficiency.

title	Space Matcher - An interactive toolbox for assisting in spatializing & testing office programmes using graph centralities
doi	https://doi.org/10.52842/conf.ecaade.2022.2.039
source	Pak, B, Wurzer, G and Stouffs, R (eds.), Co-creating the Future: Inclusion in and through Design - Proceedings of the 40th Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2022) - Volume 2, Ghent, 13-16 September 2022, pp. 39–46
summary	Graph-based representations of functional requirements (adjacencies, bubble diagram) are a common and useful method that supports architects in the conceptual phase of planning. However, the task of specifying the functional requirements through an adjacency graph can be challenging due to a quadratic growth of complexity in relation to the number of spaces. In turn, this increase of complexity challenges the designer searching for solutions that fulfill these functional requirements. There are systems that aim to address the difficulties related to graph-based space allocation. They, for instance, use fuzzy logic to weight the edges of a graph (i.e., specify relations between spaces) and spring systems (Newtonian gravitation model) to visually clarify the resulting proximity of all spaces according to the rules. Nevertheless, the problem of specifying large-scale adjacencies itself is omitted due to the assumption that such matrices are correctly filled in some previous steps. Moreover, the translation of the resulting graph into a spatial configuration is rarely supported. This work addresses these limitations and proposes a set of tools to assist the designer when defining the adjacency requirements and searching for design solutions that fulfill these requirements. Our approach aims to reduce the complexity of the design task by using graph centrality-based design heuristics. We discuss these heuristics and show their application in a scenario where a new spatial program needs to be allocated into an existing building.

title	On Visible Surface Generation by a Priori Tree Structures
source	SIGGRAPH '80 Conference Proceedings. July, 1980. vol. 14 ; no. 3: pp. 124-133 : ill. includes bibliography
summary	This paper describes a new algorithm for solving the hidden surface (or line) problem, to more rapidly generate realistic images of 3-D scenes composed of polygons, and presents the development of theoretical foundations in the area as well as additional related algorithms. As in many applications the environment to be displayed consists of polygons many of whose relative geometric relations are static. It is attempted to capitalize on this by preprocessing the environment's database so as to decrease the run-time computations required to generate a scene. This preprocessing is based on generating a 'binary space partitioning' tree whose inorder traversal of visibility priority at run-time will produce a linear order, dependent upon the viewing position, on (parts of) the polygons, which can then be used to easily solve the hidden surface problem. In the application where the entire environment is static with only the viewing-position changing, as is common in simulation, the results presented will be sufficient to solve completely the hidden surface problem

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

title	Predetermining Visibility Priority in 3-D Scenes
source	SIGGRAPH '79 Conference Proceedings. August, 1979. vol. 13 ; no. 2: pp. 175-181 : ill. includes bibliography
summary	The principal calculation performed by all visible surface algorithms is the determination of the visible polygon at each pixel in the image. Of the many possible speedups and efficiencies found for this problem, only one published algorithm (developed almost a decade ago by a group at General Electric) took advantage of an observation that many visibility calculations could be performed without knowledge of the eventual viewing position and orientation -- once for all possible images. The method is based on a 'potential obscuration' relation between polygons in the simulated environment. Unfortunately, the method worked only for certain objects; unmanageable objects had to be manually (and expertly!) subdivided into manageable pieces. Described in this paper is a solution to this problem which allows substantial a-priori visibility determination for all possible objects without any manual intervention. The method also identifies the (hopefully, few) visibility calculations which remain to be performed after the viewing position is specified. Also discussed is the development of still stronger solutions which could further reduce the number of these visibility calculations remaining at image generation time

title	Looking for the Best Place for Computer Models in Architectural Education
doi	https://doi.org/10.52842/conf.ecaade.1994.043
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. 43-46
summary	In the past, many Schools of Architecture were mastering skill of preparing hand made models and hand drawings as a main technique in design education (e.g. Warsaw School of Architecture). Introduction of CAAD to teaching process brings a new modelling techniques and a new possibilities. The role of computer models in architectural education is very promissing and still not fully recognized. Development of modelling techniques and communication media is much quicker than development of design studio concepts. Many concepts and experiments in this field had place in architectural schools all over the word. A new concept of design studio based on computer modelling techniques as a communication media is the subject of interest of the Warsaw School of Architecture. The virtuality versus reality in teaching concepts is one of the most important issues in our traditional, professionaly oriented school.

title	Incorporation of Natural Language Processing and a Generative System - An Interactive System that Constructs Topological Models from Spatial Descriptions in Natural Language
source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 205-218
summary	The natural language processing technique and the spatial reasoning technique are incorporated to create a computational model representing the process of updating and maintaining the knowledge about spatial relations. An algorithm for the spatial reasoning is proposed. An interactive system that understands sentences describing spatial relations is implemented. The system determines the reference of an anaphoric or deictic expression from the literal meaning of the input and the implicit meaning derived from the literal meaning. The consistency of the spatial relations is maintained. The correct topological representations of the spatial relations are generated from well-formed descriptions.

summary	This paper presents research on a piece-based construction information system called PCIS(pronounced “pieces”) first published as a visual information concept at ACADIA’96, Tucson. After more than five years of development it has evolved into a multidimensional visual information system for design and construction. It includes a piece-based anatomical construction model layered according to a work breakdown structure; a dataTheater that surrounds the model as an index to plans, elevations, sections, and details; and a dataWorld with cameras fixed to the intersections of its latitudes and longitudes to add context and perspective. A standard services matrix (SSM) controls layer visibility and camera settings. PCIS can be “played” to access archived resources; support design development, analyze and resolve preconstruction conflicts, and coordinate construction activities. Current research will be used to demonstrate how PCIS might be valuable to increase the potential for technical cooperation, collaboration, and communication by literally aligning the points of view of architectural, engineering, and construction methodology.

title	Growth-induced transformable surfaces realized by bending-active scissors grid
doi	https://doi.org/https://doi.org/10.1007/s44223-024-00065-0
source	Architectural Intelligence Journal
summary	Ruffled surfaces that appear in biological forms, such as coral and lettuce, are a great source of inspiration for architectural and furniture design. This paper proposes a mechanism based on a bending-active scissors grid that effectively reproduces the process of differential growth. The structure can deploy from a linearly folded state with rotational symmetry to a complex ruffled surface without rotational symmetry. The deployed shape further exhibits a wave-like motion similar to the swimming gait of flatworms or cuttlefish. First, we propose a design method for the mechanism computed from the surface of constant negative Gaussian curvature. We then numerically analyze the symmetry-breaking process of deployment and zero-stiffness wave-like motion after deployment. We built two demonstrators to verify the deployment and the transformation. The first demonstrator with 1.5m diameter was fabricated to verify the symmetry-breaking deployment motion. The second demonstrator with 0.9m diameter was fabricated to demonstrate the wave-like motion by controlled pulling of the group of threads.

summary	It is very important to collaborate not only with professional people such as designers and engineers but also with non-professional people such as clients and citizens in the field of a public design. But a maker which provides signs, lighting equipment, and street furniture etc does not always design satisfactory. This paper presents the system requirements for public design and the prototype system which reviewers can understand their position and orientation, and application of the system to the project.

title	Networked VR System: Kitchen Layout Design for Customers
source	Proceedings of the second symposium on Virtual reality modeling language, Monterey, California, United States, pp.93-100
summary	In this paper, we present our Virtual Reality (VR) technology application, a networked VR-supported design system of a kitchen layout. This networked VR system was developed on personal computers to allow customers to design at home. With the VR system, customers can have a pseudo-experience of their “virtual kitchen”, modify the design of the kitchen, and make decisions by being provided with a good idea of their potential purchase. The VR system will also play an important role in user interface in the House Design Advisory System. This system, which we are currently developing, will give advice on house design, as well as on kitchen layout design, according tothe customers’ diversified lifestyles.
