title VIRTUAL CONTEXT - INVESTIGATING THE CHARACTERISTICS AND OPPORTUNITIES OF DIGITAL VISUALISATION MEDIA FOR SITUATED APPROACHES TO ARCHITECTURAL DESIGN IN AN URBAN ENVIRONMENT
source Delft University Press
summary This research initiative addresses the issue of Design in relation to Virtual Context.

Central to this study are the innovative potentials and instrumental opportunities of computer based media techniques, capable of generating interactive models and changing perspectives for the benefit of urban and architectural design.

The ambition was to not only make a contribution to the existing body of knowledge concerning digital technologies and their applications, but explore theoretical conditions which might help define and stimulate further study.

From the outset, the focus was on furthering the opportunities for computer based representation media in creative design. On the basis of a series of explorative studies the subject of this research was targeted: the issue of Design in Context, or more specifically: Design(ing) in a Virtual Context.

During the process there was a marked shift in the conception of the subject from – more or less immersive – VR technologies in the direction of approaches which might be expected to become readily available in practice and education and could be effective in actual design processes. This insight also brought about a shift in emphasis from realism per-se towards creating a sense of situatedness.

The design representation system which was developed was intended to not just allow for one type of model view, but to afford an array of different views, from which the designer would be able to choose freely, depending on the phase and focus of design as well as personal preferences. A series of interface prototypes and support tools were developed especially and successively tested experimentally. 

For the intended final design driven experimental study, different virtual context models were considered. Eventually, an integral –  purely fictitious – design ‘environment’ was constructed in the computer, so that the workings of the proposed system and its components would be tested systematically.

A conscious choice was made for an in depth study, on a relatively modest scale, which would a certain amount of mutual involvement between designer and researcher, to confront the participants with the finer aspects of the proposed system in a relatively short time and to gather detailed data. A half dozen design professionals were invited to participate in a closely monitored experimental exercise.

The results of this study therefore do not offer straightforward, indisputable facts, to be considered representative for the design community as a whole, but indicate that the working methods of the individual designers – when discovering aspects of the site, developing and presenting proposals and reflecting on the qualities of represented designs – tend to vary considerably. For this reason the interactive representation system proved to be of value. Participants could express different view preferences, with more or less realistic image modes being used in different phases of their design developments, with varying experiences of situatedness. Some of the design professionals participants were very appreciative of the system’s opportunities, others tended to be more ‘set in their ways’.

The results of this experimental study indicate that there may particularly be opportunities for interface applications which are able to function interactively, offering individual designers –  as well as others involved in evaluating design proposals – a variety of tools with which to approach specific design artefacts in their changing contexts. Virtual models can play not only an important role as a ‘reminder’ for the designer but also to other parties playing an active role in the design and implementation processes. Interactive environment models are not only promising as exploration tools for existing sites, but could be valuable to test the impact of a design on its location. This could be especially interesting if the site is difficult or impossible to visit or as yet a virtual construction. In addition such an approach might be beneficial for objective comparison and evaluation of design proposals in competitions and in education as well as in on-line collaborative design projects where the context is still in the process of being developed.

title Parametric urban simulation: digital modeling system for building codes
source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 591-596
summary Urban building codes include a series of abstract geometric and mathematical prescriptions whose final built result is not easily visualized by non-technical users. This makes an informed public debate about the proposed regulations difficult and leaves the final definition of the exact ratios and formulas in the hands of local governments’ technical consultants. Even these experts usually have only gross numerical approximations, photomontages and other non-rigorous representations of the final built environment on which to base their decisions. We propose a system which, taking as its inputs the roads and lots of the area under consideration, as well as the proposed building codes, generates a detailed three dimensional model that gives neighbors, users and authorities’ access to a common, objective preview of the foreseeable result of the codes under consideration. We believe this will lead to a greater transparency and participation in building code definition and approval processes. [Full paper in Spanish]

title The Impact of 3D Digital Modeling on the 3D Design Aspects in Urban Design Plans
source Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 331-340

summary Some experts suggest that urban design plans in US cities may lack adequate coverage of the three-dimensional design aspects of the built environment. 3D digital models may help designers visualize and interact with design alternatives, large urban data sets, and 3D information more effectively, thus correcting this problem. Case studies of recent urban design plans that have used 3D digital models may indicate whether these technologies can increase the quality of the plan. This research discusses the role 3D urban models can play in supporting designers in addressing the 3D design aspects. A literature review focused on reviewing secondary sources to construct or adopt theoretical propositions against which the empirical data can be compared and contrasted. A case study involved investigating the methods with which 3D models have been used in developing a selected urban design plan. The content analysis of the case study refuted the premise that the plan would inadequately address 3D aspects and utilize 3D information, and indicated an effective usage of 3D modeling to analyze and represent most of the 3D and 2D information elements and issues. The results are consistent with a hypothesis that the effective usage of 3D modeling would result in the effective coverage of 3D information and issues. The effective usage of the model’s functionalities has improved the quality of the decision-making process through improving designers’ cognitive capabilities and providing a platform for communicating design ideas among and across design teams.

title Generative Design Systems for Housing

summary The present paper describes an undergoing research that aims at developing a generative design computer implementation with an outside-in approach, OIDS. The system will allow developing and visualizing context-based housing development designs. This approach will include both natural characteristics of the site and the existing neighboring buildings. It is argued that certain common urban design practices are the result of a simplification due to difficulties in dealing with the irregularities of the natural environment, which often requires the use of time-consuming methods. The computer-based application will provide tools for dealing with such difficulties, allowing designers to describe their own design rules. In an initial phase of the project, a tool that can subdivide irregular land parcels into equally sized areas has been developed. In further stages, other environmental variables will be addressed, such as solar aspect and prevalent wind directions. Eventually, even the designs of interior layouts should result from exterior forces. The resulting generative system is expected to facilitate and encourage the use of a more organic approach to building siting and design, bringing about the important discussion about which should be the main forces in the generation of the built environment.

title A Quantitative Method to Compare the Impact of Design Mediums on the Architectural Ideation Process.
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. 539-556.
summary If we compare the architectural design process to a black box system, we can assume that we now know quite well both inputs and outputs of the system. Indeed, everything about the early project either feasibility studies, programming, context integration, site analysis (urban, rural or natural), as well as the integration of participants in a collaborative process can all be considered to initiate and sustain the architectural design and ideation process. Similarly, outputs from that process are also, and to some extent, well known and identifiable. We are referring here, among others, to the project representations or even to the concrete building construction and its post-evaluation. But what about the black box itself that produces the ideation. This is the question that attempts to answer the research. Currently, very few research works linger to identify how the human brain accomplishes those tasks; how to identify the cognitive functions that are playing this role; to what extent they operate and complement each other, and among other things, whether there possibly a chain of causality between these functions. Therefore, this study proposes to define a model that reflects the activity of the black box based on the cognitive activity of the human brain. From an extensive literature review, two cognitive functions have been identified and are investigated to account for some of the complex cognitive activity that occurs during a design process, namely the mental workload and mental imagery. These two variables are measured quantitatively in the context of real design task. Essentially, the mental load is measured using a Bakan's test and the mental imagery with eyes tracking. The statistical software G-Power was used to identify the necessary subject number to obtain for significant variance and correlation result analysis. Thus, in the context of an exploratory research, to ensure effective sample of 0.25 and a statistical power of 0.80, 32 participants are needed. All these participants are students from 3rd, 4th or 5th grade in architecture. They are also very familiar with the architectural design process and the design mediums used, i.e., analog model, freehand drawing and CAD software, SketchUp. In three experimental sessions, participants were asked to design three different projects, namely, a bus shelter, a recycling station and a public toilet. These projects were selected and defined for their complexity similarity, taking into account the available time of 22 minutes, using all three mediums of design, and this in a randomly manner to avoid the order effect. To analyze the two cognitive functions (mental load and mental imagery), two instruments are used. Mental imagery is measured using eye movement tracking with monitoring and quantitative analysis of scan paths and the resulting number and duration of participant eye fixations (Johansson et al, 2005). The mental workload is measured using the performance of a modality hearing secondary task inspired by Bakan'sworks (Bakan et al.; 1963). Each of these three experimental sessions, lasting 90 minutes, was composed of two phases: 1. After calibrating the glasses for eye movement, the subject had to exercise freely for 3 minutes while wearing the glasses and headphones (Bakan task) to get use to the wearing hardware. Then, after reading the guidelines and criteria for the design project (± 5 minutes), he had 22 minutes to execute the design task on a drawing table allowing an upright posture. Once the task is completed, the subject had to take the NASA TLX Test, on the assessment of mental load (± 5 minutes) and a written post-experimental questionnaire on his impressions of the experiment (± 10 minutes). 2. After a break of 5-10 minutes, the participant answered a psychometric test, which is different for each session. These tests (± 20 minutes) are administered in the same order to each participant. Thus, in the first experimental session, the subject had to take the psychometric test from Ekstrom et al. (1978), on spatial performance (Factor-Referenced Cognitive Tests Kit). During the second session, the cognitive style is evaluated using Oltman's test (1971). Finally, in the third and final session, participant creativity is evaluated using Delis-Kaplan test (D-KEFS), Delis et al. (2001). Thus, this study will present the first results of quantitative measures to establish and validate the proposed model. Furthermore, the paper will also discuss the relevance of the proposed approach, considering that currently teaching of ideation in ours schools of architecture in North America is essentially done in a holistic manner through the architectural project.

title An Open Space with Scenery: ‘Greenscape Index’ for Performance Based Planning of High Density Urban Habitation
source CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 1, pp. 328-334
doi https://doi.org/10.52842/conf.caadria.2005.328
summary This paper presents an improvement of the original openness ratio concept, which has been formulated as an integrated index for early-stage urban open space planning and design support. The ‘greenscape index’ is a rating system which quantitatively integrates human visual perception with the visible landscape resources to evaluate the visual quality of open space vision within high-density urban environment. This new index is expected to provide more comprehensive environmental performance consideration criteria for urban planning and design. The research team also discusses the potential of the introducing this index to assess both psychological preference and physical form of urban open spaces. The new concept also has shown its feasibility on integrating key environmental considerations in visual sensitivity, urban wind, urban noise and solar heat gain into simple massing study which is applicable in the preliminary planning stage.

summary The paper details computational mapping and modeling techniques from an ongoing design research project titled Irradiated Shade, which endeavors to develop and calibrate a computational toolset to uncover, represent, and design for the unseen dangers of ultraviolet radiation, a growing yet underexplored threat to cities, buildings, and the bodies that inhabit them. While increased shade in public spaces has been advocated as a strategy for “mitigation [of] climate change” (Kapelos and Patterson 2014), it is not a panacea to the threat. Even in apparent shade, the body is still exposed to harmful, ambient, or “scattered” UVB radiation. The study region is a binational metroplex, a territory in which significant atmospheric pollution and the effects of climate change (reduced cloud cover and more “still days” of stagnant air) amplify the “scatter” of ultraviolet wavelengths and UV exposure within shade, which exacerbates urban conditions of shade as an “index of inequality” (Bloch 2019) and threatens public health. Exposure to indirect radiation correlates to the amount of sky visible from the position of an observer (Gies and Mackay 2004). The overall size of a shade structure, as well as the design of openings along its sides, can greatly impact the UV protection factor (UPF) (Turnbull and Parisi 2005). Shade, therefore, is more complex than ubiquitous urban and architectural “sun” and “shadow studies” are capable of representing, as such analyses flatten the three-dimensional nature of radiation exposure and are “blind” to the ultraviolet spectrum. “Safe shade” is contingent on the nuances of the surrounding built environment, and designers must be empowered to observe and respond to a wider context than current representational tools allow.

title Townscaping: Development of Dynamic Virtual City Augmented 3D Sketch Design Tools
source Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 105-114
summary The paper presents the development of an experimental Web-based design environment called Townscaping to be used at the conceptual stage of architectural and urban design. Inspired by Gordon Cullen's seminal work on Townscape (1960's-1970's), the idea of Townscaping is to explore how 3D digital sketch design tools could be developed to operate in connection with a dynamic virtual city system under a user's direct control. A prototype of Townscaping has been designed and implemented on the basis of an existing dynamic virtual city system. In Townscaping, a set of tools is provided for users to create and edit 3D graphic elements to be positioned directly onto the user-specified virtual city models. One of the key features of Townscaping is to enable sketching while navigation: designers can perform sketch design and gain immediate visual feedback while navigating the 3D virtual city models to any viewpoint at any moment. The current study suggests that it is feasible for virtual city models to serve as interactive urban contexts for 3D sketch design. Townscaping is considered primarily a research platform with which we are interested in investigating if designers' engaging in 3D space conceptions may be enhanced through interacting and sketching with virtual townscapes.

summary It is commonly acknowledged that ‘smart’ environments, interactive architecture and ‘smart’ homes will define the next cutting edge in architectural research. Most critics agree that one of the first problems that ‘smart’ homes will help to address is that of spiraling costs of healthcare and aging-in-place. This may be true for urban settings where there is the financial feasibility for such technologies but what about rural America? It has been conclusively proven that rural America suffers from a lack of healthcare (delivery and access). Prior research (Mathew 2005) has also established that a rural home is different from an urban home. Will technologies designed for the urban home work in a rural setting? And do rural people carry the same attitudes and biases towards technology? This paper continues our research in the design of ‘smart’ rural environments. It summarizes findings from focus group studies conducted in rural communities that help us to understand attitudes of people towards ‘smart’ technology. We will use these findings to examine the feasibility of ubiquitous computing and ‘smart’ spaces in rural areas. In conclusion, we will present guidelines to help designers in the creation of technology to augment healthy aging in rural home settings.

summary The dynamics of the city today, their conceptual changes and physical migrations place us in front of an indicial rather than symbolic phenomenology where the visuality of the of the image requires to rethink the conceptual categories for the projectual action. As architects, professors and investigators we find ourselves in front of the necessity to focus from the environment of the investigations of the coetaneous city, the system of the diverse morphologic assemblies of the urban condition, the different intervening graphologic entities and the textualities of the image in the configuration of the urbanity. It is proposed to give continuity to the presentations of investigative short essays of Sigradi 2003 and inquires of the communicational sense approached in 2004, introducing in this event schemes of investigation-teaching, exhibiting proposals of objects and designs in urban environment of the Laboratory of Formal Explorations, emphasizing the revaluation of the areas of obsolescence, the insertion of the novel outdoor public spaces and new emergent forms of the dispersion and territorial decentralization."

summary Planning workshops are known to provide important opportunities for citizen’s participation in environmental planning. The digital camera is a convenient tool for such workshops though participants still face difficulties in smooth sharing of information amongst themselves. The authors developed a prototype system for a planning workshop that applies the web-GIS technique, and devised techniques for the system-applied planning workshop through a case study. This paper discusses, first, an assumed procedure for place studies at a planning workshop; second, the functional features of the developed system; third, arrangements for the environment of the workshop; fourth, an experiment of the system use with an urban design workshop in which 91 students participated, forming 16 teams; and finally, assessment of the operational ability of the prototype and necessary refinements for in the next version.

summary Cities are becoming more complex in this digital era due to technological changes. Thinking of cities without such technological changes is equivalent to an embryonic state in the morphology of city growth, that is, the growth seems less advanced. So it is appropriate to think of the non digital city digitally. Urban design is one state which establishes the perfect relationship between the street, people and building. The relationship of the people with the building and street is becoming one of the key factors in architecture. It has been observed that the design of a city has been influenced by the pedestrian movement. Many cities prior to the industrial era were largely determined by the social interactions based on walking. Thus the pedestrians play a key role in the formation of the city. They are a very important component in any representation of transport movements. They generally terminate or initiate a chain of linked activities, and if observed carefully, a single pedestrian movement is meant to include various sub journeys from one location to another. In order to organize pedestrians, we need to understand the pedestrian movement system. Though there is a lot of development of urban models in this aspect, it is still in a nascent state in comparison with the digital advancement. Thus much research work is carried out which can be applied to any given environmental setting, and as a result urban designers can respond to the changing socio-cultural technologies.

source Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary This paper describes an experimental practice-based research project that considered design process, implementation and construction of a pavilion built to be part of the Performative Space section of the International Biennale of Contemporary Art, Prague 2005. The project was conceptualized as a time-bound performative situation with a parasite-like relationship to its host environment. Its design has emerged through an innovative iterative process that utilized digital simulative and procedural techniques and was formed in response to place-specific behavioral challenges. This paper presents the project as an in-depth case-study of digital methods in design, mass customization and unified methods of production. In particular, it considers the use of Voronoi patterns for production of structural elements providing detail on programming and construction techniques in relationship to design aspirations and practical constraints.

title RECONCILING COMPUTER AND HAND: THE CASE OF AUTHOR IDENTITY IN DESIGN PRESENTATIONS

summary As computers were newly emerging in the field of architectural design, it was claimed that the impact of computers would change the way architects design and present. However, within the course of computer use in design, although the field of architectural practice might have been altered extremely, in architectural education there still seems to be a bond to conventional mind-hand-paper relation. One of the reasons for that bond is the fact that although being r 1000 elated to many technologies, architecture essentially positions itself around an artistic core that is still fed with conventional modes of creation. Architectural education aims at adopting and working on this very core. One of the major contributors in the formation of this core is the presence of author identity. This paper makes a critical approach to computers in terms of expressing author identity in design presentations especially during design education. We believe that the author identity is important in design education in terms of identifying the potential and skills of the student. Especially in design education the final step of design process turns out to be the presentation, unlike architectural practice where the presented design is actually built. Within this conception, two different studies were held in an educational environment with 160 design students and 20 design instructors. The results of both studies pointed at the fact that the digital opportunities that exist for design education should evolve around preserving and underlining the author identity in design presentations.

title Thonet Chairs Design Grammar: a Step Towards the Mass Customization of Furniture
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. 181-200.
summary The paper presents the first phase of research currently under development that is focused on encoding Thonet design style into a generative design system using a shape grammar. The ultimate goal of the work is the design and production of customizable chairs using computer assisted tools, establishing a feasible practical model of the paradigm of mass customization (Davis, 1987). The current research step encompasses the following three steps: (1) codification of the rules describing Thonet design style into a shape grammar; (2) implementing the grammar into a computer tool as parametric design; and (3) rapid prototyping of customized chair designs within the style. Future phases will address the transformation of the Thonet’s grammar to create a new style and the production of real chair designs in this style using computer aided manufacturing. Beginning in the 1830’s, Austrian furniture designer Michael Thonet began experimenting with forming steam beech, in order to produce lighter furniture using fewer components, when compared with the standards of the time. Using the same construction principles and standardized elements, Thonet produced different chairs designs with a strong formal resemblance, creating his own design language. The kit assembly principle, the reduced number of elements, industrial efficiency, and the modular approach to furniture design as a system of interchangeable elements that may be used to assemble different objects enable him to become a pioneer of mass production (Noblet, 1993). The most paradigmatic example of the described vision of furniture design is the chair No. 14 produced in 1858, composed of six structural elements. Due to its simplicity, lightness, ability to be stored in flat and cubic packaging for individual of collective transportation, respectively, No. 14 became one of the most sold chairs worldwide, and it is still in production nowadays. Iconic examples of mass production are formally studied to provide insights to mass customization studies. The study of the shape grammar for the generation of Thonet chairs aimed to ensure rules that would make possible the reproduction of the selected corpus, as well as allow for the generation of new chairs within the developed grammar. Due to the wide variety of Thonet chairs, six chairs were randomly chosen to infer the grammar and then this was fine tuned by checking whether it could account for the generation of other designs not in the original corpus. Shape grammars (Stiny and Gips, 1972) have been used with sucesss both in the analysis as in the synthesis of designs at different scales, from product design to building and urban design. In particular, the use of shape grammars has been efficient in the characterization of objects’ styles and in the generation of new designs within the analyzed style, and it makes design rules amenable to computers implementation (Duarte, 2005). The literature includes one other example of a grammar for chair design by Knight (1980). In the second step of the current research phase, the outlined shape grammar was implemented into a computer program, to assist the designer in conceiving and producing customized chairs using a digital design process. This implementation was developed in Catia by converting the grammar into an equivalent parametric design model. In the third phase, physical models of existing and new chair designs were produced using rapid prototyping. The paper describes the grammar, its computer implementation as a parametric model, and the rapid prototyping of physical models. The generative potential of the proposed digital process is discussed in the context of enabling the mass customization of furniture. The role of the furniture designer in the new paradigm and ideas for further work also are discussed.

title Morphological transformations in Brazilian peripheral areas: a case study of the Vila Cabral neighborhood at Campina Grande-PB
source SIGraDi 2020 [Proceedings of the 24th Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Online Conference 18 - 20 November 2020, pp. 112-119
summary This article describes an analysis of the morphological changes between 2005 and 2020 in the Vila Cabral neighborhood, located on the outskirts of the Brazilian city of Campina Grande. The research was developed in two different analytical scenarios, adopting the algorithmic- parametric computational implementation as a methodology, and applying the following procedures: (i) formal decomposition of a sample of the urban fabric; (ii) visibility graph analysis (VGA); (iii) analysis of the diversity of uses and (iv) analysis of urban density (populational and built). The study demonstrated that the association of different urban analysis tools strengthens decision-making in the context of evidence-based urban design.

summary Computer aided modelling and drafting protocols – in combination with new production technologies – have contributed to wholly new ways of shaping building elements. Some examples of new techniques, which have recently become very successful in building production and in architectural design education, are: 3D Rapid Prototyping; 2,5D and 3D Milling and computer aided Shape Cutting (notably using laser and water jet modes). Such new approaches not only create new opportunities for traditional production processes (including physical modelling), they also offer new perspectives for design and manufacturing on the level of architectural components and connections. We foresee innovative approaches to building product design, with a renewed interest in expressive Ornamentation. A phenomenological development we would like to address using the concept of ‘Ornamatics’. This contribution explores the potentials of product design with a renewed focus on ornamentation, involving the active utilization of computer aided modelling and manufacturing techniques. The paper furthermore documents results and findings of a series of explorative studies carried out within an educational laboratory environment.

title On the ways of expression in present architecture
source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 679-683
summary This paper aims at introducing the main aspects of a research on architectural representation and the usage of new technologies in the process of development of an architectural project, which has been conducted at a department of Graphical Expression. The authors of this paper would like to outline the most excellent and innovating aspects introduced by a number of architectural proposals which involve actively the application of these techniques. The chosen case studies for this paper are among the European contemporary architectural panorama. The authors will analyze some projects of architectural studios which were involved in the urban transformation brought about by celebration of the Forum of the Cultures 2004. These new ways of architectural representation have had, in this specific case, a significant effect within the context of a technological revolution that allows the conception of new forms and textures and the reflection on the increasingly complex processes to generate architectural space.

title Digital Art A Field of Inquiry for Contemporary Architecture
source International Journal of Architectural Computing vol. 3 - no. 3, 355-372
summary This article investigates the interplay of digital technology, art and architecture and it presents a series of experimental workshops developed at LAGEAR (Graphic Laboratory for the Experience of Architecture, School of Architecture at UFMG, Brazil). The intention of these workshops is to include an artistic approach to the work in a computer lab dedicated to teaching and researching architecture. At first, a discussion on the relationship between art and architecture is presented, followed by an analysis of the enhancement of such relationship with the advent of digital technology. Then a series of works developed by artists and students in collaboration is described. The article concludes with a discussion on the role of digital art for architectural education. It is proposed that it may be one of the most adequate fields for students to freely investigate contemporary issues, such as interactivity and automation, which are now shaping our built environment.

title A 3D Model of the Inner City of Beijing

summary This study has two major concentrations: 1) exploring methods of creating a digital city model, and 2) applying the model to study urban spatial structure, an issue of particular interest and importance to urban planners. Based on existing studies that primarily address two-dimensional (2D) urban structure, this paper focuses on the three-dimensional (3D) structure relating to the 3D urban form. Given their greater clarity and possibilities for quantitative analysis, both 3D digital urban models and GIS spatial overlay analysis methods hold tremendous potential for analysing and predicting future urban form. In this project, the Xidan Business District in Beijing's Inner City was the area selected to implement the digital-city application. Under the hypothesis that the existing urban spatial structure is determined by the city's urban planning scheme and current urban marketing forces, it is found that actual urban development does not follow the planning restrictions on zoning and building height regulations. Some contradictions and conflicts, such as building location and height, appeared in the studied district. The specific reasons for the discrepancies need to be further studied.
