summary The 3D SketchMaker Project has developed two prototypes for a gestural 3D sketching system to be used in the earliest phases of the design process. The goal of this ongoing research is to provide architects, and other designers involved in object conception, with a 3D gestural instrument that takes advantage of new virtual reality resources and is more naturalthan using the mouse, less difficult than learning complex software and less abstract than manipulating 2D entities on orthogonal projections. The focus of this project is on the input interface, taking into consideration two factors: First, for many architects and designers, one of the main reasons for not using 3D modeling from the very beginning of the design process is that both current hardware and software are hardly appropriate to do the spontaneous and quick drawings that are used to assist in conceptualizing their objects.

summary The 3D SketchMaker Project has developed two prototypes for a gestural 3D sketching interface in a computer system to be used in the earliest phases of the design process. The goal of this ongoing research is to provide architects, and other designers involved in object conception, with a 3D gestural instrument that takes advantage of new virtual reality resources and is more natural than using the mouse, less difficult than learning complex software and less abstract than manipulating 2D entities on orthogonal projections. The focus of this project is on the input interface, taking into consideration two factors: First, for many architects and designers, one of the main reasons for not using 3D modeling from the very beginning of the design process is that both current computer hardware and software are hardly appropriate to do the spontaneous and quick drawings that are used to assist in conceptualizing their objects. Second, three-dimensional modeling packages use two-and-three dimensional elements, in a 3D environment, but usually employ 2D input devices that are not appropriate to work in 3D environments, such as mice or pen-and-tablets. The 3D SketchMaker was conceived to take advantage of a natural tendency most people have in using gesture as an aid to language when trying to describe the shape, form or volume of objects. The system is intended to assist or replace the first 2D drawing steps in the design process, generating rough 3D sketches that can be refined later. It is, in essence, a 3D modeling system (a prototype, at this time) directed to do sketching with hand movements and gestures in a virtual reality environment.

title APPLICATION OF SPATIAL DESIGN ABILITY IN A POSTGRADUATE COURSE
source Full-scale Modeling and the Simulation of Light [Proceedings of the 7th European Full-scale Modeling Association Conference / ISBN 3-85437-167-5] Florence (Italy) 18-20 February 1999, pp. 75-82
summary Spatial Design Ability (SDA) has been defined by the author (1983) as the capacity to anticipate the effects (psychological impressions) that architectural spaces or its components produce in observers or users. This concept, which requires the evaluation of spaces by the people that uses it, was proposed as a guideline to a Masters Degree Course in Architectural Design at the Universidad Autonoma de Aguascalientes in Mexico. The theory and the exercises required for the experience needed a model that could simulate spaces in terms of all the variables involved. Full-scale modeling as has been tested in previous research, offered the most effective mean to experiment with space. A simple, primitive model was designed and built: an articulated ceiling that allows variation in height and shape, and a series of wooden panels for the walls and structure. Several exercises were carried out, mainly to experience cause -effect relationships between space and the psychological impressions they produce. Students researched into spatial taxonomy, intentional sequences of space and spatial character. Results showed that students achieved the expected anticipation of space and that full-scale modeling, even with a simple model, proved to be an effective tool for this purpose. The low cost of the model and the short time it took to be built, opens an important possibility for Institutions involved in architectural studies, both as a research and as a learning tool.

title Automated Cost Analysis of Concept Design BIM Models
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 403-418.
summary AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

title Virtual Reality in Early Design: the Design Studio Experiences
source AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999, pp. 327-335
summary The Design Systems group of the Eindhoven University of Technology started a new kind of design studio teaching. With the use of high-end equipment, students use Virtual Reality from the very start of the design process. Virtual Reality technology up to now was primarily used for giving presentations. We use the same technology in the design process itself by means of reducing the time span in which one gets results in Virtual Reality. The method is based on a very brief cycle of modelling in AutoCAD, assigning materials in 3DStudio Viz, and then making a walkthrough in Virtual Reality in a standard landscape. Due to this cycle, which takes about 15 seconds, the student gets immediate feedback on design decisions which facilitates evaluation of the design in three dimensions much faster than usual. Usually the learning curve of this kind of software is quite steep, but with the use of templates the number of required steps to achieve results is reduced significantly. In this way, the potential of Virtual Reality is not only explored in research projects, but also in education. This paper discusses the general set-up of the design studio and shows how, via short workshops, students acquire knowledge of the cycle in a short time. The paper focuses on the added value of using Virtual Reality technology in this manner: improved spatial reasoning, translation from two-dimensional to three-dimensional representations, and VR feedback on design decisions. It discusses the needs for new design representations in this design environment, and shows how fast feedback in Virtual Reality can improve the spatial design at an early stage of the design process.

title Time sections, abstract machines
source International Conference on Generative Art
summary conditions a time-spatial discontinuity in the urban grid, ancient walls casually discovered in a substrate of the contemporary town needs a surplus of information to be understood and interfaced with their current condition. diagrams diverse chronological stages of the urban evolution are mapped on the area, in order to read the historical stratifications as a multiplicity of signs; this abstract approach leads to consider the roman space as guided by metrics, a system of measure superimposed on the landscape, vs. medioeval spatial continuity, where more fluid relations between the same urban elements create a completely different pattern.assemblage (time sections) a surface, automatically displaced from the medioeval diagram, moves along the z axis, the historical stratification direction, intersecting in various, unpredictable, manners a series of paths; these paths start as parallels, allowing an undifferentiated access to the area, and mutate along their developing direction, intertweening and blending each other; linear openings are cut on the surface, virtually connecting the two levels by light, following the roman grid in rhythm and measure. Projected on the lateral wall, the cadence of the vertical and horizontal elements becomes a temporal diagram of the design process.movement time takes part into the process through two kinds of movement: the first one, freezed when reaches the best results, in terms of complexity, is given by the surface intersecting the tubular paths; the second one is represented by multiple routes walking on which the project can be experienced (in absence of any objective, fixed, point of view, movement becomes the only way to understand relations). Thresholds between typical architectural categories (such as inside-outside, object-landscape etc.) are blurred in favour of a more supple condition, another kind of continuity (re)appears, as a new media, between the different historical layers of the city.

title CAD Interfaces to the ARROW Manufactured Product Server
source Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 1-11
summary The UK national project ARROW (Advanced Reusable Reliable Objects Warehouse) provides an Internet based framework through which it is possible to identify any of a range of manufactured products meeting specific design criteria. This open framework (based upon the IAI's IFCs) provides a mechanism for users to search for products from any participating manufacturer or supplier based both on specific attributes of a product or on any of the textual descriptions of the product. The service returns the closest matching products and allows the user to navigate to related information including manufacturer, suppliers, CAD details, VR displays, installation instructions, certificates, health and safety information, promotional information, costings, etc. ARROW also provides a toolkit to enable manufacturers and suppliers to more easily map and publish their information in the format utilised by the ARROW system. As part of the ARROW project we have examined the ability to interface from a design tool through to ARROW to automatically retrieve information required by the tool. This paper describes the API developed to allow CAD and simulation tools to communicate directly with ARROW and identify appropriate manufactured information. The demonstration system enables CAD systems to identify the closest matching manufactured product to a designed product and replacing the designed product with the details supplied by the manufacturer for the manufactured product as well as pulling through product attributes utilised by the design application. This paper provides a description of the ARROW framework and issues faced in providing information based upon standards as well as containing information not currently modelled in public standards. The paper looks at issues of enabling manufacturers and suppliers to move from their current world-view of product information to a more data-rich and user accessible information repository (even though this enables a uniform comparison across a range of manufacturer's products). Finally the paper comments on the likely way forward for ARROW like systems in providing quality information to end users.

title Image and Shape: Two Distinct Approaches
source III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 410-415
summary This paper is the result of two researches done at the district of Campeche, Florianópolis, by the Grupo PET/ARQ/UFSC/CAPES. Different aspects and conceptual approaches were used to study the spatial attributes of this district located in the Southern part of Santa Catarina Island. The readings and analysis of two researches were based on graphic pistures builded with the use of Corel 7.0 e AutoCadR14. The first research – "Urban Development in the Island of Santa Catarina: Public Space Study"- examined the urban structures of Campeche based on the Spatial Syntax Theory developed by Hillier and Hanson (1984) that relates form and social appropriation of public spaces. The second research – "Topoceptive Characterisation of Campeche: The Image of a Locality in Expansion in the Island of Santa Catarina" -, based on the methodology developed by Kohlsdorf (1996) and also on the visual analysis proposed by Lynch (1960), identified characteristics of this locality with the specific goal of selecting attributes that contributed to the ideas of the place its population held. The paper consists of an initial exercise of linking these two methods in order to test the complementarity of their analytical tools. Exemplifying the analytical procedures undertaken in the two approaches, the readings done - global (of the locality as a whole) and partial (from parts of the settlement) - are presented and compared.

title Space Syntax and the New Transportation System in the Santa Catarina Island
source III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 434-437
summary The paper reports an on-going research that aims at describing and analysing some of the syntactic characteristics of the urban space of Santa Catarina Island, in an attempt to evaluate its performance, more specifically its social and spatial integration and segregation. The research has been conducted with the aid of the Aximagic software, still in exam stage and not yet released to the public, a tool being developed by a group of researches of the Rio Grande do Sul Federal University and given up by Prof. Doctor Benamy Turkienicz. The software is part of a larger georeferenced program called CityZoom wich includes others tools to the comprehention of the urban morphology. This program works with graphic pictures in the inlet of data and also in the acquisition of results. The syntactic study of the Santa Catarina Island as a whole aims to obtain the comprehension of its global structure, relating it to the integrated public transportation system proposed to Florianópolis. These studies should allow an understanding of the impact the developments will have upon the urban morphology, and the new public transportation system.

title Evaluation of Spatial Perception in Virtual Environments
source III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 145-148
summary The 3D environments created by computers can be used as a powerful simulation tool for architecture, especially with inmersive devices, but it is necessary to know properly their spatial characteristics to use it effectively. It is also important to consider their possibilities in communication networks and their implications in contemporary architecture. For this reason, the goal of this research is to evaluate the perception of virtual architectonic spaces in relation to the perception of real architectonic spaces. This research is based on the comparison of experiences of university students in a real space (Entrance Hall of Faculty of Economy) and in the same space modeled by a computer. The evaluation considers tests with stereoscopic helmets and interactive navigation, making questionnaires to characterize the sensation of dimensions, relationships and time for an specific activity. The measuring of real and virtual spaces are made through references (furniture, textures, etc.) or by proportional relations between height, width and depth, in different patterns. The experience also reveals mental schemes to perceive the dimension of architectonic space and the orientation in a real and virtual environment. Besides, the research allows to relate the different levels of complexity and information with the understanding of real architectonic space and modeled space.

source Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 700-707
summary Our paper presents recent developments of a co-operation program that links the MAP-GAMSAU CNRS laboratory (Marseilles, France), specialised in computer science and the HAiKZ Institute of Krakow's Faculty of Architecture, specialised in architectural heritage and conservation. Before undertaking any action to a listed building or interventions in its neighbourhood, it is vital to gain a clear understanding of the building in question. Numerous heterogeneous data detained by diverse institutions has to be handled. This process can be greatly eased by enhanced classification of the information. The development we present is a multidisciplinary platform independent information tool dedicated to education and research. SOL uses an http protocol centred computer architecture connecting a relational database, a VRML 2.0 representation module and a web search interface. It allows searches and updating of the database through a standard text based interface, a VRML 2.0 graphical module and a thematic interface. SOL is experienced on the urban fabric of the Main Square (Rynek Gówny) in Kraków. The choice of a web-centred development, both in the search and updating interface and in the representation module provides platform independence and distant access to the database, and enables successive contributions of students or researchers.

title Spatial multimedia and virtual reality
source London: Taylor & Francis
summary The intersection of two disciplines and technologies which have become mature academic research topics in the 1990s was destined to be a dynamic area for collaboration and publication. However, until now no significant book-length treatment of the meeting of GIS and Virtual Reality has been available. This volume puts that situation to rights by bringing these together to cement some common understanding and principles in a potentially highly promising area for technological collaboration and cross-fertilisation. The result is a volume which ranges in subject matter from studies of a Virtual GIS Room to Spatial Agents, and from an Environmental Multimedia System to Computer-Assisted 3D Geographic Education. All the contributors are well-known international scientists, principally from the computational side of GIS. It will be a valuable resource for any GIS researcher or professional looking to understand the leading edge of this fertile field. ------------------------------------------------------------------------

title GIS and the Investigation of the Environmental Heritage
source III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 219-224
summary This paper presents an investigation on the architectural, natural, and cultural resources in the southern part of the state of Rio Grande do Sul, according to their historical or environmental value, identifying natural and cultural elements known and valued by local communities, regardless their experts’ classification. Resources are identified by means of geographical information systems, combined with field information. The area comprises the coastal strip and the plains located in the last frontier of the Brazilian territory and the water system dominated by the lakes Patos, Mangueira and Mirim. The inventory of the environmental, sociocultural and economic heritage provides the necessary insight for issuing new development alternatives based on local resources. Research activities will include: the ellaboration of general and thematic maps, based on LANDSAT 5 [bands 3, 4 and 5] images; aerial photographs; DSG/SGE and municipal maps [scales 1:250.000, 1:50.000 and 1:25.000]; field work for the recognition of remarkable elements; interviews with residents for assessing their perception of local values; and community and institutional statements. These informations, comprising the elements valued by their architectural and urban quality, historical relevance and environmental significance, organised in a database, will provide contextual guidelines for the planning of a tourist route. This route, delineated by the preservation, recovery and use of representative local resources, valued as expressions of a native culture, evocates the initial occupation of the gaúcho territory, and may be touristically promoted as "The Gaúcho’s Way". The project also aims at showing the potential offered by GIS for identifying and evaluating specific spatial characteristics.

summary This work presents the study and applied assays (or simulation tests) about the ordination of urban space in the region of Lagoa da Conceição. In the region pressures placed by the growth of urban area and urban network system are in contact conflict with a fragile ecosystem, and with a sustainable development based on tourism. Analysis procedures exploited different forms of Space Syntax trying to examine effects of spatial structure in relation to movement patterns of pedestrians and vehicles. This methodology allowed the comprehension of relation between spatial configuration, transport and soil use, and reveled the interdependence and performance of built space within the restrict regional scale (Lagoa da Conceição) and the total urban structure of the island. This understanding is not limited to the present. Is also includes the study of historic urban evolution, and simulation of existing projects for the future, being an important tool to support project decision process. Consequently, the obtained results bring a new approach for the problem, which makes possible the synthesis of design proposals verifying its implications and consequences.

summary Art historians and critics have defined the style as common features appeared in a class of objects. Abstract common features from a set of objects have been used as a bench mark for date and location of original works. Common features in shapes are identified by relationships as well as physical properties from shape descriptions. This paper will focus on how the computer recognises common shape properties from a class of shape objects to learn style. Shape representation using schema theory has been explored and possible inductive generalisation from shape descriptions has been investigated.

summary This research project developed an electronic library of significant buildings chosen to represent seven selected periods of Western architectural history: Egyptian (Mortuary temple of Queen Hatshepsut), Greek (Parthenon), Roman (Pantheon), Romanesque (Speyer Cathedral), Gothic (Notre Dame Cathedral), Renaissance (Tempietto), and Modern (Des Moines Art Center). All buildings were reconstructed in their original or intended forms based on plans, drawings, photographs, and historical texts. Two products were generated by this project: (1) materials to be displayed on the World Wide Web, including rendered still images for perception, movies for a visual guide, and Virtual Reality Modeling Language (VRML) models for user navigation; and (2) virtual reality (VR) models to be displayed in the C2 (an improved version of the Cave Automatic Virtual Environment or CAVE facility). The benefits of these VR models displayed on the Web and in the C2 are their easy accessibility at any time from various geographic locations and the immersive experience that enhances viewersÌ understanding of the effects of spatial proportions on form and of colors on materials.

summary University of Oregon Architecture Department has developed a spectrum of digital design from introductory methods courses to advanced design studios. With a computing curriculum that stresses a variety of tools, architectural issues such as form-making, communication, collaboration,theory-driven design, and presentation are explored. During the first year, all entering students are required to learn 3D modeling, rendering, image-processing and web-authoring in our Introduction to Architectural ComputerGraphics course. Through the use of cross-platform software, the two hundred beginning students are able to choose to work in either MacOS or Windows. Students begin learning the software by ‘playing’ with geometric elements and further develop their control by describing assigned architectural monuments. In describing the monuments, they begin with 2D diagrams and work up to complete 3D compositions, refining their modelswith symbol libraries. By visualizing back and forth between the drafting and modeling modes, the students quickly connect orthogonal plans and sections with their spatial counterparts. Such connections are an essential foundation for further learning.

summary This paper depicts the approach of constructing a virtual reality environment for simulating architectural design and construction operations. The virtual environment is established to demonstrate the spatial performance of design and constructability of construction operations. Particularly, the functions such as navigation of construction sites, simulation of construction operations, and evaluation of construction details will be critical to construction operations. The system shell is implemented by JAVA on the web and integrated with VRML for supporting the above functions. The study focuses on the needs for the system integration and interface design. Four modes of human computer interfaces are proposed, including the user, agent, monitor, and immersion modes. Finally, this paper provides demonstration of construction simulation in an office building project to highlight the above discussion. The operations of crane towers and curtain wall installation are also studied in the construction process. In conclusion, this paper demonstrates the potential uses and limitation of virtual reality in simulation of the built environment.

title The use of genetic programming for applications in the field of spatial composition
source International Conference on Generative Art
summary Architectural design teaching using computers has been a preoccupation of CECA since 1991. All design tutors provide their students with a set of models and ways to form, and we have explored a set of approaches including cellular automata, genetic programming ,agent based modelling and shape grammars as additional tools with which to explore architectural ( and architectonic) ideas.This paper discusses the use of genetic programming (G.P.) for applications in the field of spatial composition. CECA has been developing the use of Genetic Programming for some time ( see references ) and has covered the evolution of L-Systems production rules( coates 1997, 1999b), and the evolution of generative grammars of form (Coates 1998 1999a). The G.P. was used to generate three-dimensional spatial forms from a set of geometrical structures .The approach uses genetic programming with a Genetic Library (G.Lib) .G.P. provides a way to genetically breed a computer program to solve a problem.G. Lib. enables genetic programming to define potentially useful subroutines dynamically during a run .* Exploring a shape grammar consisting of simple solid primitives and transformations. * Applying a simple fitness function to the solid breeding G.P.* Exploring a shape grammar of composite surface objects. * Developing grammarsfor existing buildings, and creating hybrids. * Exploring the shape grammar of abuilding within a G.P.We will report on new work using a range of different morphologies ( boolean operations, surface operations and grammars of style ) and describe the use of objective functions ( natural selection) and the "eyeball test" ( artificial selection) as ways of controlling and exploring the design spaces thus defined.
