title Videomodeling in Architecture. Introduction into Concerned Problems
source Proceedings of the 8th European Architectural Endoscopy Association Conference
summary Since the very 1st year Russian Academy of Architecture and building sciences that was established in 1992 by the Presidents’ decree as the higher scientific and creative organization in the country has always paid much attention to supporting and developing fundamental investigations in architecture, town-planning, building sciences, professional education and creative practice. Study of the birth process of the architectural idea and searching for tools assisting the architect’s creative activity and opportunities for adequate transfer of architectural image to potential consumer – relate to the number of problems which constantly bother the architectural community. Before turning to the conference, let us set certain conditions that have a significant impact on the development of architectural and construction activity in modern Russia.

title Learning Physics by Computer in an Architectural School
source CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 473-476
summary A method is proposed for computerised problem-solving related to beam bending, using a programme of symbolic calculus. This approach permits easy posing of the equations to be solved. The algebraic logical enables the problem posed to be solved easily. The fact that the data can be entered in symbol form, not necessarily in numerical form, enables the student, when analysing the solution, to become familiar with the system behaviour, which is an essential aspect for support of the project task.

title CoDraw “Graphical Constraints in CoDraw”
source IEEE Workshop on Visual Languages, Seattle, WA, pp. 81-87
summary Constraint based draw programs require users to understand and manage relationships between drawing elements. By establishing constraint relationships among elements the user effectively programs the drawing's behavior. This programming task requires a more sophisticated visual interface than conventional draw programs provide. Users must have available - in a convenient format - information about the structure of the constraints that determine the drawing's interactive edit behavior. This format must support editing and debugging. CoDraw is a constraint based drawing program that can be interactively extended by its users. This paper describes the CoDraw program and its programming interface.

title Spatial Perception in Perspective Displays
source Report Human-Computer Interaction Lab, Virginia
summary Increasingly, computer displays are being used as the interface "window" between complex systems and their users. In addition, it is becoming more common to see computer interfaces represented by spatial metaphors, allowing users to apply their vast prior knowledge and experience in dealing with the three-dimensional (3D) world (Wickens, 1992). Desktop VR or window on a world (WoW), as it is sometimes called, uses a conventional computer monitor to display the virtual environment (VE). The 3D display applies perspective geometry to provide the illusion of 3D space.

title Discontinuity Meshing for Radiosity
source Eurographics Workshop on Rendering. May 1992, pp. 203-216
summary The radiosity method is the most popular algorithm for simulating interreflection of light between diffuse surfaces. Most existing radiosity algorithms employ simple meshes and piecewise constant approximations, thereby constraining the radiosity function to be constant across each polygonal element. Much more accurate simulations are possible if linear, quadratic, or higher degree approximations are used. In order to realize the potential accuracy of higher-degree approximations, however, it is necessary for the radiosity mesh to resolve discontinuities such as shadow edges in the radiosity function. A discontinuity meshing algorithm is presented that places mesh boundaries directly along discontinuities. Such algorithms offer the potential of faster, more accurate simulations. Results are shown for three-dimensional scenes.

title CAD geometry data exchange using STEP
source Berlin: Springer-Verlag
summary With increasing demand for data exchange in computer integrated manufacturing, a neutral connection between dissimilar systems is needed. After a few national and European attempts, a worldwide standardization of product data has been developed. Standard ISO 10303 (STEP - STandard for Exchange of Product data) produced in its first version those parts that are relevant for CAD geometrical data. A European consortium of 14 CAD vendors and users was supported by the ESPRIT programme to influence the emerging standard and implement early applications for it. Over the years 1989-1992, project CADEX (CAD geometry data EXchange) worked out application protocols as a contribution to STEP; developed a software toolkit that reads, writes, and manipulates STEP data; and, based on this toolkit, implemented data exchange processors for ten different CAD and FEA systems. This book reports the work done in project CADEX and describes all its results in detail.

title Playing with Time - Continuous Temporal Mapping Strategies for Interactive Environments
source 6th Canadian GIS Conference, (Ottawa Natura Resources Canada), pp. 318-329
summary The growing acceptance of GIS technology has had far- reaching effects on many fields of research. The recent developments in the area of dynamic and temporal GIS open new possibilities within the realm of historical research where temporal relationship analysis is as important as spatial relationship analysis. While topological structures have had wide use in spatial GIS and have been the subject of most temporal GIS endeavours, the different demands of many of these temporally- oriented analytic processes questions the choice of the topological direction. In the fall of 1992 the Montreal Research Group (MRG) of the Canadian Centre for Architecture mounted an exhibition dealing with the development of the built environment in 18th- century Montreal. To aid in presenting the interpretive messages of their data, the MRG worked with the Centre for Landscape Research (CLR) to incorporate the interactive capabilities of the CLR's PolyTRIM research software with the MRG's data base to produce a research tool as well as a public- access interactive display. The interactive capabilities stemming from a real- time object- oriented structure provided an excellent environment for both researchers and the public to investigate the nature of temporal changes in such aspects as landuse, ethnicity, and fortifications of the 18th century city. This paper describes the need for interactive real- time GIS in such temporal analysis projects and the underlying need for object- oriented vs. topologically structured data access strategies to support them.

title Working in Virtual Environments through appropriate Physical Interfaces
source Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 431-436
summary The work described here is aimed at contributing towards the debate and development relating to the construction of interfaces to explore buildings and their environs through virtual worlds. We describe a particular hardware and software configuration which is derived by the use of low cost games software to create the Virtual Environment. The Physical Interface responds to the work of other researchers, in this area, in particular Shaw (1994) and Vasquez de Velasco & Trigo (1997). Virtual Evironments might have the potential to be "a magical window into other worlds, from molecules to minds" (Rheingold, 1992), but what is the nature of that window? Currently it is often a translucent opening which gives a hazy and distorted (disembodied) view. And many versions of such openings are relatively expensive. We consider ways towards clearing the haze without too much expense, adapting techniques proposed by developers of low cost virtual reality systems (Hollands, 1995) for use in an architectural setting.

title Monitoring the Dynamics of Informal Settlements in Dar Es Salaam by Remote Sensing: Exploring the Use of Spot, Ers and Small Format Aerial Photography
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary Dar es Salaam is exemplary for cities in the developing world facing an enormous population growth. In the last decades, unplanned settlements have tremendously expanded, causing that around 70 percent of the urban dwellers are living now-a-days in these areas. Tools for monitoring such tremendous growth are relatively weak in developing countries, thus an effective satellite based monitoring system can provide a useful instrument for monitoring the dynamics of urban development. An investigation to asses the ability of extracting reliable information on the expansion and consolidation levels (density) of urban development of the city of Dar es Salaam from SPOT-HRV and ERS-SAR images is described. The use of SPOT and ERS should provide data that is complementary to data derived from the most recent aerial photography and from digital topographic maps. In a series of experiments various classification and fusion techniques are applied to the SPOT-HRV and ERS-SAR data to extract information on building density that is comparable to that obtained from the 1992 data. Ultimately, building density is estimated by linear and non-linear regression models on the basis of an one ha kernel and further aggregation is made to the level of informal settlements for a final analysis. In order to assess the reliability, use is made of several sample areas that are relatively stable over the study period, as well as, of data derived from small format aerial photography. The experiments show a high correlation between the density data derived from the satellite images and the test areas.

title Discontinuity Meshing for Accurate Radiosity
source IEEE Computer Graphics & Applications, November 1992, pp.25-38
summary We discuss the problem of accurately computing the illumination of a diffuse polyhedral environment due to an area light source. We show how umbra and penumbra boundaries and other illumination details correspond to discontinuities in the radiance function and its derivatives. The shape, location, and order of these discontinuities is determined by the geometry of the light sources and obstacles in the environment. We describe an object-space algorithm that accurately reproduces the radiance across a surface by constructing a discontinuity mesh that explicitly represents various discontinuities in the radiance function as boundaries between mesh elements. A piecewise quadratic interpolant is used to approximate the radiance function, preserving the discontinuities associated with the edges in the mesh. This algorithm can be used in the framework of a progressive refinement radiosity system to solve the diffuse global illumination problem. Results produced by the new method are compared with ones obtained using a standard radiosity system.

title Tools for Visual Simulation of Space and their Use by Students
source Architecture & Behaviour vol. 8, no. 3:175-187
summary Most visual representations of architectural space are still done using drawings of ground plan, section and view. Yet, when experience is lacking - as with students or laypeople these two-dimensional representations hardly show their correspondence to a three-dimensional reality. This article examines the various visual techniques for spatial simulation available today and their implementation by students involved with architectural projects.

title On Measuring Project Performance : Some Problems of Aggregation
source New York: John Wiley & Sons, 1992. pp. 239-249 : tables. includes bibliography
summary Performance evaluation of buildings--by means of postconstruction evaluation--has traditionally focused on the performance measurement of building subsystems. This approach, based on the horizontal view of the building process, suffers from two important shortcomings. First, its underlying assumption that a completed building's performance can be arrived at simply by aggregating the individual performances of its parts is not valid. Like most complex systems, a completed building is much more than the sum of its parts. Second, the focus of traditional appraisal on subsystems, with its feedback information on individual products and services, actively encourages suboptimization of tasks. It is a condition that is contrary to the requirements imposed by the multiorganizational nature of the building team, and the resulting interdependence of tasks, where useful feedback information is that which relates to the project as a whole. To overcome these shortcomings of the traditional building appraisal model, an alternative model based on the vertical view of the building process is proposed

title Towards the 4th Dimension
source CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 91-100
summary Fifteenth century Europeans 'knew' that the sky was made of closed concentric crystal spheres, rotating around a central earth and carrying the stars and planets. That 'knowledge' structured everything they did and thought, because it told them the truth. Then Galileo's telescope changed the truth. As a result, a hundred years later everybody 'knew' that the universe was open and infinite, working like a giant clock. Architecture, music, literature, science, economics, art, politics - everything - changed, mirroring the new view created by the change in the knowledge. The medium by which perceptive intuition and the rigorous discipline of shaping became compatible was technology. Technelogos, the art of knowing how to make, fell naturally and historically into the realm of perceptive fundamentals... For the artist it verified scientifically what he had perceived emotionally; for the engineer it added the vast field of perceptive responses to the narrow limits of the laboratory experiment.

title Modeling the structure of the flow experience
source INFORMS Marketing Science and the Internet Mini-Conference, MIT
summary The flow construct (Csikszentmihalyi 1977) has recently been proposed by Hoffman and Novak (1996) as essential to understanding consumer navigation behavior in online environments such as the World Wide Web. Previous researchers (e.g. Csikszentmihalyi 1990; Ghani, Supnick and Rooney 1991; Trevino and Webster 1992; Webster, Trevino and Ryan 1993) have noted that flow is a useful construct for describing more general human-computer interactions. Hoffman and Novak define flow as the state occurring during network navigation which is: 1) characterized by a seamless sequence of responses facilitated by machine interactivity, 2) intrinsically enjoyable, 3) accompanied by a loss of self-consciousness, and 4) selfreinforcing." To experience flow while engaged in an activity, consumers must perceive a balance between their skills and the challenges of the activity, and both their skills and challenges must be above a critical threshold. Hoffman and Novak (1996) propose that flow has a number of positive consequences from a marketing perspective, including increased consumer learning, exploratory behavior, and positive affect."

summary With the development of storage media such as the CD ROM, the availability and usage of very large data bases of information has dramatically opened new vistas for the creation of electronic libraries. From dictionaries and encyclopedias to historical treatises, the electronic packaging of large and cumbersome information sources has begun to demonstrate its utility and efficiency. Today the bridge to an unknown territory of electronic knowledge resources lies here at the boundary between the passive (though electronically accelerated) access to information through electronic books and the user interactive access to knowledge. This paper is about that boundary.
