summary ¿Can the computer improves the architectural creativity? This question is explored through a Virtual-Reality system developed for the modeling of timber structures, based on parametric elements, constructive programming and immersive visualization on real-time. Making experiences of evaluation with advanced students of architecture, whose use the system in the beginning of projects, compared with other group use not the system. This research faces the possibilities to rationalizate part of the creative process in architecture, broading the role of computer and its contribution to quality of design, and extending the possibilities to teach and share the creation of project. It is argue that major potential in this field is the swiftness, formal variety and spatial living of design, challenging the differences between objective and subjective.

title XML for Flexibility an Extensibility of Design Information Models

summary The VR-DIS research programme aims at the development of a Virtual Reality – Design Information System. This is a design and decision support system for collaborative design that provides a VR interface for the interaction with both the geometric representation of a design and the non-geometric information concerning the design throughout the design process. The major part of the research programme focuses on early stages of design. The programme is carried out by a large number of researchers from a variety of disciplines in the domain of construction and architecture, including architectural design, building physics, structural design, construction management, etc.Management of design information is at the core of this design and decision support system. Much effort in the development of the system has been and still is dedicated to the underlying theory for information management and its implementation in an Application Programming Interface (API) that the various modules of the system use. The theory is based on a so-called Feature-based modelling approach and is described in the PhD thesis by [first author, 1999] and in [first author et al., 2000a]. This information modelling approach provides three major capabilities: (1) it allows for extensibility of conceptual schemas, which is used to enable a designer to define new typologies to model with; (2) it supports sharing of conceptual schemas, called type-libraries; and (3) it provides a high level of flexibility that offers the designer the opportunity to easily reuse design information and to model information constructs that are not foreseen in any existing typologies. The latter aspect involves the capability to expand information entities in a model with relationships and properties that are not typologically defined but applicable to a particular design situation only; this helps the designer to represent the actual design concepts more accurately.The functional design of the information modelling system is based on a three-layered framework. In the bottom layer, the actual design data is stored in so-called Feature Instances. The middle layer defines the typologies of these instances in so-called Feature Types. The top layer is called the meta-layer because it provides the class definitions for both the Types layer and the Instances layer; both Feature Types and Feature Instances are objects of the classes defined in the top layer. This top layer ensures that types can be defined on the fly and that instances can be created from these types, as well as expanded with non-typological properties and relationships while still conforming to the information structures laid out in the meta-layer.The VR-DIS system consists of a growing number of modules for different kinds of functionality in relation with the design task. These modules access the design information through the API that implements the meta-layer of the framework. This API has previously been implemented using an Object-Oriented Database (OODB), but this implementation had a number of disadvantages. The dependency of the OODB, a commercial software library, was considered the most problematic. Not only are licenses of the OODB library rather expensive, also the fact that this library is not common technology that can easily be shared among a wide range of applications, including existing applications, reduces its suitability for a system with the aforementioned specifications. In addition, the OODB approach required a relatively large effort to implement the desired functionality. It lacked adequate support to generate unique identifications for worldwide information sources that were understandable for human interpretation. This strongly limited the capabilities of the system to share conceptual schemas.The approach that is currently being implemented for the core of the VR-DIS system is based on eXtensible Markup Language (XML). Rather than implementing the meta-layer of the framework into classes of Feature Types and Feature Instances, this level of meta-definitions is provided in a document type definition (DTD). The DTD is complemented with a set of rules that are implemented into a parser API, based on the Document Object Model (DOM). The advantages of the XML approach for the modelling framework are immediate. Type-libraries distributed through Internet are now supported through the mechanisms of namespaces and XLink. The implementation of the API is no longer dependent of a particular database system. This provides much more flexibility in the implementation of the various modules of the VR-DIS system. Being based on the (supposed to become) standard of XML the implementation is much more versatile in its future usage, specifically in a distributed, Internet-based environment.These immediate advantages of the XML approach opened the door to a wide range of applications that are and will be developed on top of the VR-DIS core. Examples of these are the VR-based 3D sketching module [VR-DIS ref., 2000]; the VR-based information-modelling tool that allows the management and manipulation of information models for design in a VR environment [VR-DIS ref., 2000]; and a design-knowledge capturing module that is now under development [first author et al., 2000a and 2000b]. The latter module aims to assist the designer in the recognition and utilisation of existing and new typologies in a design situation. The replacement of the OODB implementation of the API by the XML implementation enables these modules to use distributed Feature databases through Internet, without many changes to their own code, and without the loss of the flexibility and extensibility of conceptual schemas that are implemented as part of the API. Research in the near future will result in Internet-based applications that support designers in the utilisation of distributed libraries of product-information, design-knowledge, case-bases, etc.The paper roughly follows the outline of the abstract, starting with an introduction to the VR-DIS project, its objectives, and the developed theory of the Feature-modelling framework that forms the core of it. It briefly discusses the necessity of schema evolution, flexibility and extensibility of conceptual schemas, and how these capabilities have been addressed in the framework. The major part of the paper describes how the previously mentioned aspects of the framework are implemented in the XML-based approach, providing details on the so-called meta-layer, its definition in the DTD, and the parser rules that complement it. The impact of the XML approach on the functionality of the VR-DIS modules and the system as a whole is demonstrated by a discussion of these modules and scenarios of their usage for design tasks. The paper is concluded with an overview of future work on the sharing of Internet-based design information and design knowledge.

title An Expandable Software Model for Collaborative Decision-Making During the Whole Building Life Cycle
doi https://doi.org/10.52842/conf.acadia.2000.019
source Eternity, Infinity and Virtuality in Architecture [Proceedings of the 22nd Annual Conference of the Association for Computer-Aided Design in Architecture / 1-880250-09-8] Washington D.C. 19-22 October 2000, pp. 19-28
summary Decisions throughout the life cycle of a building, from design through construction and commissioning to operation and demolition, require the involvement of multiple interested parties (e.g., architects, engineers, owners, occupants and facility managers). The performance of alternative designs and courses of action must be assessed with respect to multiple performance criteria, such as comfort, aesthetics, energy, cost and environmental impact. Several stand-alone computer tools are currently available that address specific performance issues during various stages of a building’s life cycle. Some of these tools support collaboration by providing means for synchronous and asynchronous communications, performance simulations, and monitoring of a variety of performance parameters involved in decisions about a building during building operation. However, these tools are not linked in any way, so significant work is required to maintain and distribute information to all parties. In this paper we describe a software model that provides the data management and process control required for collaborative decision-making throughout a building’s life cycle. The requirements for the model are delineated addressing data and process needs for decision making at different stages of a building’s life cycle. The software model meets these requirements and allows addition of any number of processes and support databases over time. What makes the model infinitely expandable is that it is a very generic conceptualization (or abstraction) of processes as relations among data. The software model supports multiple concurrent users, and facilitates discussion and debate leading to decision-making. The software allows users to define rules and functions for automating tasks and alerting all participants to issues that need attention. It supports management of simulated as well as real data and continuously generates information useful for improving performance prediction and understanding of the effects of proposed technologies and strategies.

title Interactive Representation of Architectural Design: The Virtual Design Studio as an Architectural Graphics Laboratory
doi https://doi.org/10.52842/conf.ecaade.1999.459
source Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 459-465
summary This paper introduces the Virtual Design Studio (VDS), an internet based design studio environment established by ifib. VDS transfers lessons learned through research projects in the field of Computer Supported Co-operative Work (CSCW) being carried out at ifib into design education. By training for interdisciplinary co-operation within the design process, the students will become better prepared for the flexibility and co-operability required in planning situations. Increasing the communication and co-operation in the planning process can be achieved through the implementation of IT based virtual workspaces. In the design studio setting, this is done through the use of available internet software and technologies. The methodology of the VDS is briefly described including specific assignments intended to focus student investigations into specific areas including the representation of their work using the world wide web. The pedagogical expectations are discussed and anecdotal evidence precedes an general evaluation of the teaching method. The authors postulate that one of the unintended by-products of the studio is the evolution of an effective use of interactivity in the presentation of design concepts, ideas and solutions. A handful of student work is presented to describe the different approaches taken in using the world wide web (WWW) to display project work. A description of the local evolution (VDS specific) of graphical methods and technologies is followed by a comparison with those used in traditional settings. Representation is discussed with focus on the ability of the WWW to replace, augment or corrupt other methods of presentation. The interactive nature of web based presentations induces alterations to the narration of architectural work and can enhance the spatial perception of design space. Space Perception can be enabled through geometrically true VRML representations, the inclusion of auditory sensations, the abstraction of representation through the use of advertising techniques as well as the introduction of non-linear narrative concepts. Examples used by students are shown. A critical assessment of these new representational methods and the place of current new media within the context of architectural representation is discussed.

summary Founded in 1995 LAB[au], laboratory for architecture and urbanism, links theoretic research LAB[a+u] to concrete works of conception and realisations LA.BAU. LAB[au] elaborates a “hyperdesign” investigating the implications of new technologies of communication and computation in spatiotemporal and social processes and their forms of representation as architecture and urbanism. The transposition of the hypertext model to architectural and urban concepts question the mutation of the spatial and semantic construct of space. The definition of architecture as a code is based on “glocal” systems according to the processes of computation and communication.

summary Since 1991 Virtual Reality has been used in student projects in the Building Information Technology group. It started as an experimental tool to assess the impact of VR technology in design, using the environment of the associated Calibre Institute. The technology was further developed in Calibre to become an important presentation tool for assessing design variants and final design solutions. However, it was only sporadically used in student projects. A major shift occurred in 1997 with a number of student projects in which various computer technologies including VR were used in the whole of the design process. In 1998, the new Design Systems group started a design studio with the explicit aim to integrate VR in the whole design process. The teaching effort was combined with the research program that investigates VR as a design support environment. This has lead to increasing number of innovative student projects. The paper describes the context and history of VR in Eindhoven and presents the current set-UP of the studio. It discusses the impact of the technology on the design process and outlines pedagogical issues in the studio work.

title Creating a City Administration System (CAS) using Virtual Reality in an Immersive Collaborative Environment (ICE)
doi https://doi.org/10.52842/conf.ecaade.2001.449
source Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 449-453
summary Current problems in administration of a city are found to be decentralized and noninteractive for an effective city management. This usually will result in inconsistencies of decision-making, inefficient services and slow response to a particular action. City administration often spends more money, time and human resource because of these problems. This research demonstrates our research and development of creating a City Administration System (CAS) to solve the problems stated above. The task of the system is to use information, multimedia and graphical technologies to form a database in which the city administrators can monitor, understand and manage an entire city from a central location. The key technology behind the success of the overall system uses virtual reality and immersive collaborative environment (ICE). This system employs emerging computer based real-time interactive technologies that are expected to ensure effective decisionmaking process, improved communication, and collaboration, error reduction, (Rafi and Karboulonis, 2000) between multi disciplinary users and approaches. This multi perspective approach allows planners, engineers, urban designers, architects, local authorities, environmentalists and general public to search, understand, process and anticipate the impact of a particular situation in the new city. It is hoped that the CAS will benefit city administrators to give them a tool that gives them the ability to understand, plan, and manage the business of running the city.

title Intuitive and Effective Design of Periodic Symmetric Tiles

source Eternity, Infinity and Virtuality in Architecture [Proceedings of the 22nd Annual Conference of the Association for Computer-Aided Design in Architecture / 1-880250-09-8] Washington D.C. 19-22 October 2000, pp. 123-127
summary This paper presents a new approach for intuitive and effective design of periodic symmetric tiles. We observe that planar graphs can effectively represent symmetric tiles and graph drawing provides an intuitive paradigm for designing symmetric tiles. Moreover, based on our theoretical work to represent hexagonal symmetry by rectangular symmetry, we are able to present all symmetric tiles as graphs embedded on a torus and based on simple modulo operations. This approach enables us to develop a simple and efficient algorithm, which has been implemented in Java. By using this software, designers, architects and artists can create interesting symmetric tiles directly on the web. We also have designed a few examples of symmetric tiles to show the effectiveness of the approach.

summary Based on a comparison between the perception of digital and real construction, the development of virtual systems and the review of additional sources, this paper states some differences between the design of virtual environments and architectural spaces. Virtual-reality technologies provide advanced capabilities to simulate real situations, and also to create digital worlds not referred to physical places, such as imaginary landscapes or environments devoted to electronic activities, like entertainment, learning or commerce. Some on-line services already use 3D-stages, resembling building halls and domestic objects, and several authors have mentioned virtual modeling as a job opportunity to architects. But it will argue in this paper that the design of those environments should consider their own digital characteristics. Besides, the use of virtual installations on networks impells a convergence with global media, like Internet or TV. Virtual environments can be a 3Devolution of communicational technologies, which have an increasing participation in culture, reaching a closer relationship to contemporary architecture.
