title	A Computational Approach to the Reconstruction of Surface Geometry from Early Temple Superstructures
source	International Journal of Architectural Computing vol. 3 - no. 4, 471-486
summary	Recovering the control or implicit geometry underlying temple architecture requires bringing together fragments of evidence from field measurements, relating these to mathematical and geometric descriptions in canonical texts and proposing "best-fit" constructive models. While scholars in the field have traditionally used manual methods, the innovative application of niche computational techniques can help extend the study of artefact geometry. This paper demonstrates the application of a hybrid computational approach to the problem of recovering the surface geometry of early temple superstructures. The approach combines field measurements of temples, close-range architectural photogrammetry, rule-based generation and parametric modelling. The computing of surface geometry comprises a rule-based global model governing the overall form of the superstructure, several local models for individual motifs using photogrammetry and an intermediate geometry model that combines the two. To explain the technique and the different models, the paper examines an illustrative example of surface geometry reconstruction based on studies undertaken on a tenth century stone superstructure from western India. The example demonstrates that a combination of computational methods yields sophisticated models of the constructive geometry underlying temple form and that these digital artefacts can form the basis for in depth comparative analysis of temples, arising out of similar techniques, spread over geography, culture and time.

summary	With the recent developments in computer technology studies on how to digitally restore traditional buildings to their original state are being pursued. It is highly important that the public can be educated by digitally restoring these buildings online and/or offline. However, it is necessary to develop several techniques to understand a structural order and construction process in traditional buildings. We propose new techniques that we can better understand them and fit them into society in the education and the publicity.

title	Dry-In House: A Mass Customized Affordable House for New Orleans
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 359-362
summary	Dry-in house is a mass customized affordable housing system proposed for the reconstruction of New Orleans. The dry-in House gets the owner back to their home site quickly while providing the infrastructure an occupant needs (shelter, water, electricity). The owner is supplied with an inhabitable shell that is customizable before it is fabricated as well as onsite as the project is “fitted out” over time. The key concept is to allow families to participate in the design of their customized homes and to get people back to their home sites as quickly as possible and to give them the opportunity to finish and further customize their home over time. The project addresses inefficiencies and redundancies in emergency housing currently provided by FEMA. Primarily the dry-in House as its name implies provides a timely dried-in space which doubles as a customized infrastructure for the reconstruction of homes and neighborhoods. The project is designed to meet the $59,000 life cycle cost of the presently provided temporary housing, the notorious “FEMA Trailer”. However, the Dry-in House provides a solution that: a) Is permanent rather than temporary. The house will be finished and further customized over time rather than disposed of. b) Reoccupies the owner’s home site rather than a “FEMA ghetto” keeping the community together and functioning. c) Is mass customized rather than mass-standardized allowing the owner to have input on the design of their home. The design is a “starter home” rather than an inflexible and over-determined solution. This also has the benefit of giving variation to the reconstruction of New Orleans as opposed to the monotony of mass-production. d) Allows the owners to further customize their home over time with additional exterior finishes and the subdivision and fit out of the interior. By utilizing plate truss technology and associated parametric modeling software, highly customized trusses can be engineered and fabricated at no additional cost as compared to off-the-shelf trusses. This mass customization technology is employed to create the building section of each individual’s house. The truss is not used in its typical manner, spanning over the house; rather, it is extruded in section to form the house itself (roof, wall, and floor). Dry-in House exploits this building technology to quickly rebuild communities in a sensible manner. It allows for an increased speed of design and construction and most importantly it involves the owner in this process. The process has other benefits like reducing waste not only because it replaces the FEMA trailer which is expensive and disposable but also since the components are prefabricated there is more precision and also quality. The Dry-in House allows the owner-designer to “draw” the section of their new home providing them with a unique design and a sense of belonging and security. The design of the section of the house also provides them with spatial configurations customized relative to site conditions, program etc... Because of the narrow lot configuration of New Orleans, the design maximizes the roof as a source for natural ventilation and light for the interior of the house. In addition, the house is one room deep providing cross ventilation in all rooms minimizing reliance on artificial mechanical systems. The timely and efficient off site fabrication of building sections facilitate larger concentrations of volunteers on site at one time, thereby promoting a greater collective spirit among the community and volunteer workforce, a therapeutic event for the community as they participate in the rebuilding of their homes and city. With individualized building sections arriving on site, the construction process is imagined to be more akin to a barn raising, making possible the drying in of multiple houses in less than one day.

summary	A strong dichotomy exists between the factors of fluctuating natural orders apparent in the river, and the striation of the land by human historical and cultural influence. The installation exists as surface of influence between these forces. The form is informed by parameters of light, vista, material, and process through a method of digitally folding and perforating sheets of steel to enable a self structuring membrane which rises and falls from the plateau edge. A swath of prairie grasses, rising and falling in their own cycle, demarcates this edge. A screen of 15 weathering steel sheets stretches for 63’ across the boundary of the human order and the encroaching erosion of the natural realm. From the initial generation of geometry pairings, well “adapted” pairings are spliced from the parent and “bred” with similarly fit geometries. The fit of these pairs is based on the relationships between the form and the desired criteria of reflection, screening, and framing. To properly combine these pairings, several mutations occur (indicated in red).

title	Mass-Customization in the Design of 4,000 Bus Stops
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. 265-278.
summary	In Hawaii, ‚"TheBus‚" has been a main transportation system since 1971. Considering the high cost of living in Hawaii and the absence of a rail system, the use of ‚"TheBus‚" has been an instrumental vein of the city life in Honolulu with rhythmical pauses at about 4,000 bus stops in Honolulu. However, existing undifferentiated bus stops are developed from a cost effective mass production system so that they have been problematic for satisfying specific needs from various site conditions. In this research, an integrated computational method of mass-customization for designing 4,000 bus stops is introduced. According to various site conditions, the design of each bus stop is customized. Unlike the mass‚Äêproduced bus stops commonly seen in cities today, the proposed computational method in this paper produces bus stop design outcomes that fit into the physical characteristics of the location in which they are installed. Mass-customization allows for the creation and production of unique or similar buildings and building components, differentiated through digitally‚Äêcontrolled variation (Kolarevic, 2003). The employment of a computational mass‚Äêcustomization in architectural design extends the boundary of design solutions to the satisfaction of multi-objective requirements and unlimited freedom to search alternative solutions (Duarte, 2001; Caldas, 2006). The computational method developed in this paper consists of 1) definition of a prototype, 2) parametric variation, 3) manual deformation, and 4) simulation based deformation. The definition of a prototype is the development of a basic design to be transformed for satisfying various conditions given from a site. In this paper, the bus stop prototype is developed from the analysis of more than 300 bus stops and the categorization of the existing bus stops according to their physical conditions, contextual conditions, climatic conditions, and existing amenities. Based upon the outcome of the analysis, the design variables of a bus stop prototype are defined. Those design variables then guide the basic physical parameters for changing the physical configuration of the prototype according to a given site. From this, many possible design outcomes are generated as instances for further developments. The process of manual deformation is where the designer employs its intuition to develop the selected parametric variation. The designer is compelled to think about the possible implication derived from formal variation. This optional process allows every design decision to have a creative solution from an individual designer with an incidental quality in aesthetics, but substantiated functional quality. Finally the deformation of the selection is guided and controlled by the influence of sun direction/ exposure to the selection. The simulation based deformation starts with the movement of the sun as the trigger for generating the variations of the bus stop prototype. The implementation of the computational method was made within the combination of MEL (Maya Enbedded Language), autodesk MAYA and Ecotect environment.

title	Towards a Digital Design Teaching Tool - A look at the ideas that should define a digital design primer
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Progress in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN-10: 90-386-1756-9, ISBN-13: 978-90-386-1756-5, p. 373-386
summary	Architecture in the 21st century has become an increasingly complex affair. In addition to new social and cultural norms, architects are inundated with constantly changing information regarding new materials, sustainable processes, and complex building types. This state of affairs has also affected the expectations placed on architectural education. Critics (in diverse spheres) have expressed concerns about the lack of requisite skills of graduates that characterise good design thinking strategies as well as promote responsible design. It has been proposed by this author in other forums that by using digital technology to empower design learning, we can allow students to confidently use (through reading and analysis) their sketches to develop conceptual ideas that reconcile disparate elements into a habitable, environmentally friendly and architecturally responsible whole that is fit for purpose, cost effective, sustainable and a delight to clients and users. This paper will seek to discuss one of the concepts that govern such a tool. It will start by delineating the problem (discussed earlier in the abstract) before outlining the concepts or principles that a design teaching tool should adhere to. These concepts acknowledge the importance for the tool to reflect the nature of design tasks, facilitate learning and be accessible to all learning types. The paper will then focus on one concept - the nature of design tasks. The subsequent sections will describe an information structure borne from this idea and make mention of a current prototype of the tool. The paper will conclude with a discussion of the strengths of considering this concept.

summary	Modest in budget and ephemeral in nature, STOCK SPACE was installed, exhibited, and dismantled over a five-day period at the Toronto National Trade Center as part of an invited exhibition of concept spaces at the 2005 Toronto Interior Design Show. Occupying 450 square feet within an 110,000-square-foot convention center, STOCK SPACE was small, vertical, warm, and quiet, in contrast to the immense horizontality of the mechanically cooled trade floor of nearly 40,000 exhibitors and attendees. STOCK SPACE was an investigation of limits. Material had to fit through doors and on our CNC milling bed. It had to clear staircases, be carried by hand, and be stored compactly within the confines of our fabrication area. STOCK SPACE was an exercise in subtraction. The space was created through the removal of stock material from a conceptually full volume that measured 24’ long x 18’ wide x 12’ tall. High density EPS foam in 4’x 8’ x 16” modules provided a light and machinable medium capable of recording the vestigial marks of fabrication as well as providing adequate dampening and insulation. The resulting assemblage of stacked modules embodied traits of the orthographic grid associated with the length and width of the stock, the topographic contours associated with the depth of the stock and the isoparametric grooves of the resulting surface. The collective composition of these elements was the analytical result of maximum machining curvature.

title	Design Informatics: a case based investigation into parametric design scripting and CNC based manufacturing techniques
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	The research paper exemplifies a novel information integrated design technique developed at ONL (Oosterhuis and Lenard), Netherlands, specifically appropriated for manifesting complex geometric forms. The ‘informed design technique’, apart from being highly instrumental in conceptualizing and generating the geometric component constituting architectural form in a parametric manner, is also efficiently utilized for precise computer aided manufacturing and construction of the speculated form. Geometric complexities inherent in contemporary architectural constructs and the time spent in appropriation of such topologies, fueled the ‘informed design’ approach, which caters to issues of timely construction, precision oriented design and production (visual and material) and parametric modeling attuned to budgetary fluctuations. This designresearch approach has been tested and deployed by ONL, for conceiving ‘the Acoustic Barrier’ project, Utrecht Leidsche Rijn in the Netherlands and is treated as a generic case for exemplifying the ‘informed design’ technique in this research paper. The design methodology encourages visualizing architectural substantiations from a systems perspective and envisages upon a rule based adaptive systems approach involving extrapolation of contextual dynamics/ground data in terms of logical ‘rules’. These rules/conditionalities form the basis for spawning parametric logistics to be mapped upon geometric counterparts exemplifying the conception. The simulated parametric relations bind dimensional aspects (length, width, height etc.) of the geometric construct in a relational manner, eventually culminating in a 3D spatial envelope. This evolved envelope is subsequently intersected with a ‘parametric spatio-constructive grid’, creating specific intersecting points between the two. A pattern of points attained from this intersection: ‘the point cloud’ serves as a generic information field concerning highly specific coordinates, parameters and values for each individual point/constructive node it embodies. The relations between these points are directly linked with precise displacements of structural profiles and related scaling factors of cladding materials. Parallel to this object oriented modeling approach, a detailed database (soft/information component) is also maintained to administer the relations between the obtained points. To be able to derive constructible structural and cladding components from the point cloud configuration customized Scripts (combination of Lisp and Max scripts) process the point cloud database. The programmed scriptroutines, iteratively run calculations to generate steel-wire frames, steel lattice-structure and cladding panels along with their dimensions and execution drawing data. Optimization-routines are also programmed to make rectifications and small adjustments in the calculated data. This precise information is further communicated with CNC milling machines to manifest complex sectional profiles formulating the construct thus enabling timely and effective construction of the conceptualized form.

title	Hybrid modeling revaluing manual action for 3D modeling
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 392-402
doi	https://doi.org/10.52842/conf.acadia.2006.392
summary	3D modeling software uses conventional interface devices like mouse, keyboard and display allowing the designer to model 3D shapes. Due to the complexity of 3D shape data structures, these programs work through a geometrical system and a graphical user interface to input and output data. However, these elements interfere with the conceptual stage of the design process because the software is always asking to be fed with accurate geometries—something hard to do at the beginning of the process. Furthermore, the interface does not recognize all the advantages and skills of the designer’s bare hands as a powerful modeling tool.This paper presents the evaluation of a hybrid modeling technique for conceptual design. The hybrid modeling approach proposes to use both computer and manual tools for 3D modeling at the beginning of the design process. Using 3D scanning and rapid prototyping techniques, the designer is able to go back and forth between digital and manual mode, thus taking advantage of each one. Starting from physical models, the design is then digitalized in order to be treated with special modeling software. Then, the rapid prototyping physical model becomes a matrix or physical 3D template used to explore design intentions with the hands, allowing the proposal of complex shapes, which is difficult to achieve by 3D modeling software alone.

title	Immersive Drafted Virtual Reality a new approach for ideation within virtual reality
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 304-316
doi	https://doi.org/10.52842/conf.acadia.2006.304
summary	There is a void between design and computer in ideation. Traditional tools like sketching are more appropriate for conceptual design since they can sustain abstraction, ambiguity, and inaccuracy—essentials at the beginning of the design process. Actual graphical user interface approaches, as well as hardware devices, constrain creative thinking. Computer representations and virtual reality are now used for presentation and validation rather than for design. Most virtual reality tools are seen as passive rather than active instruments in this process of ideation. Moreover, virtual reality techniques come from other disciplines and are applied to design without considering the design process itself and the skills designers already possess.This paper proposes and evaluates a new approach for the conceptual design of spaces within virtual reality. Starting from the non-immersive technique we developed before, where the user was able to be inside a 3D modeled space through real sketches, this technique goes one step further, allowing the designer to sketch the space from the inside all in real-time. Using an interactive pen display for sketching and an immersive projective spherical display, designers and colleagues are able to propose and make design decisions from inside the project. The capabilities of the computer to display the virtual environment are, therefore, mixed with the designer’s skills in sketching and understanding the space.

summary	Subject of study is the possible organisation of the Olympic Games of 2028 in the Netherlands, as seen from an urban development viewpoint. The project focuses on the decision-making process in the initiative phase. Aim of the project is the development of a decision support tool for the complex, interdisciplinary decision-making process which should result in an optimum interorganisational design. The methodology used to find the optimum choice is the combination of sub-solutions. Preference Measurement modelling based on a multi-criteria decision analysis is the technique employed. The group decision is a choice out of a number of Olympic urban development combinations, which is made in such a way that the preferred combination is the 'best' among the possible candidates for all relevant stakeholders.

summary	This approach intends to develop a consulting capacity in design and technological management for the sustainable growth, supporting local communities with specific resources. In the development of the technological knowledge transfer, the acritical applications, under the cover of paradigms of technological globalization that give their back to the local contexts, and of the irrelevant pedagogical routines, dissociate the technology from its social meaning. In our research approach, the transfer experience is the unit of analysis which under observation relocates and redefines technique in the context of sustainable local development, uncovering its relations with society. In this work, we will show one experience that explain the contribution of design to sustainable development, experiences that specially reveal the need to count with criteria and indicators of technological performance in participative and inclusive scenarios.

summary	Simulation is a means to help urban planners and investors to optimize inhabitant satisfaction and return on investment. An example is the optimal match between household preferences and property profiles. The problem is that not enough knowledge exists yet about dynamic user activity models to build reliable and realistic simulators. Therefore, we propose a modeling and software technique that produces simulator prototypes very efficiently for the development, test, and evaluation of many different user activity models, using executable models, code generation, and a domain specific software process. As a specific feature, the model is based on many agents acting independently from each other and that are mapped in several refinement steps into the same number of concurrent processes. The housing example is used as a case study to explain the process and show performance results.

summary	Architecture always has an environmental impact. By using simulations, planners can minimize the environmental impact. Since simulations normally take a long time and thus only allow a very limited number of iterations, our project describes the setup of a close-to-real-time simulation technique. By dividing the simulation into smaller parts and running the software on clusters or massively parallel computing platforms, first results are available within several seconds, reasonable results below one minute. In order to make this tool easily accessible to specialists and laymen, a tangible user interface provides an intuitive interaction method. The results of the simulation can be visualized and interacted with in different virtual environments. Limitations, mainly automatic grid generation, shape recognition and computation power are discussed.

title	Flexible Formwork Research (FPR)

doi	https://doi.org/10.52842/conf.acadia.2006.x.r8t
summary	FFR investigates the self-organization of plaster and elastic fabric to produce evocative visual and acoustic effects. Inspired by the work of the Spanish architect Miguel Fisac and his experiments with flexible concrete formwork in the 1960-70s, FFR continues this line of research by exploring aspects of pattern generation and recognition in relation to self-organized form. In line with the theme of the current exhibition, Digital Exchange, the work can be understood as a dialog between physical and digital computation. The form is a result of a negotiation between the digital manipulation of images and the physical deformations of materials under stress. Both digital and physical processes play an equal role in the final form of the plaster tiles.Reflecting on Miguel Fisac’s flexible concrete formwork, there was a desire to investigate the potential for more differentiated patterns while still using the same basic fabrication technique. This was accomplished through the use of a custom-designed script in Rhino that analyzes a given image and translates it into a field of points. These points establish areas of constraint in the elastic membrane of the mould. Through numerous physical tests, the minimum and maximum distances between constraint points was determined and these were entered into the script as limits for the point creation. If the points are too close, large wholes with very thin and weak plaster form whereas if the points are too far apart the amount of elastic deformation is so great that the weight of the plaster can cause failures to occur in the fabric mould. One of the most important aspects of the project is its resonance with the body and our natural attraction and repulsion for certain forms. Through exploring the natural self-organization of material under stress, FFR unintentionally reminds us of our own flesh. The plaster tiles resonate with our own body’s material as it sags, expands, and wrinkles in relationship with gravity, structure, and time.

summary	This paper presents an experiment using digital photogrammetry for the restitution of urban forms, using precise and low cost techniques, an alternative solution for the cartographic actualization of cities. The technique uses digital cameras (non-metric), with resolution compatible with the precision and scale required for the products. This process simplifies the acquisition of the photos, that can be taken by different places: in the ground, in the top of high buildings or by small airplanes or ultralights, in opposition of the traditional image acquisition method, done by costly aerial photogrammetric flights, realized by specialized companies.

This design-research approach has been tested and deployed by ONL, for conceiving ‘the Acoustic Barrier’ project, Utrecht Leidsche Rijn in the Netherlands and is treated as a generic case for exemplifying the ‘informed design’ technique in this research paper. The design methodology encourages visualizing architectural substantiations from a systems perspective and envisages upon a rule based adaptive systems approach involving extrapolation of contextual dynamics/ground data in terms of logical ‘rules’. These rules/conditionalities form the basis for spawning parametric logistics to be mapped upon geometric counterparts exemplifying the conception. The simulated parametric relations bind dimensional aspects (length, width, height etc.) of the geometric construct in a relational manner, eventually culminating in a 3D spatial envelope. This evolved envelope is subsequently intersected with a ‘parametric spatio-constructive grid’, creating specific intersecting points between the two. The hence extorted ‘point cloud’ configuration serves as a generic information field concerning highly specific coordinates, parameters and values for each individual point/constructive node it embodies. The relations between these points are directly linked with precise displacements of structural profiles and related scaling factors of cladding materials. Parallel to this object oriented modeling approach, a detailed database (soft/information component) is also maintained to administer the relations between the obtained points. To be able to derive constructible structural and cladding components from the point cloud configuration customized Scripts (combination of Lisp and Max scripts) process the point cloud database. The programmed script-routines, iteratively run calculations to generate steel-wire frames, steel lattice-structure and cladding panels along with their dimensions and execution drawing data. Optimization-routines are also programmed to make rectifications and small adjustments in the calculated data. This precise information is further communicated with CNC milling machines to manifest complex sectional profiles formulating the construct hence enabling timely and effective construction of the conceptualized form.

title	Optimal Distribution of Architecture Programs with Multiple-constraint Genetic Algorithm

summary	A genetic algorithm (GA) is a search technique for optimizing or solving a problem based on evolutionary biology, using terms and processes such as genomes, chromosomes, cross-over, mutation, or selection. The evolution starts from a population of completely random individuals and happens in generations. In each generation, the fitness of the whole population is evaluated, multiple individuals are stochastically selected from the current population (based on their fitness), modified (mutated or recombined) to form a new population, which becomes current in the next iteration of the algorithm. In architecture, GAs are of special interest mainly because of their ability to address a problem offering a multiplicity of possible solutions. Contrary to other algorithms where the objective is to accommodate a manually conceived diagram, GAs are emergent procedures that evolve over time through multiple attempt cycles (i.e. generations) and therefore offer a bottom-up approach to design. In addition, by using the computational power of computers they can resolve complex interactions between multiple factors and under multiple constraints offering solutions that occasionally surprise the designer. One of the main problems in architecture today is the quantity of the information and the level of complexity involved in most building projects. As globalization and economic development has started to arise at unprecedented levels, the need for large urban developments have become commonplace. Housing projects for a few hundreds to thousands of people have started to emerge over large urban areas. In such cases, the old paradigm for housing design was the development of high rises that served as stacking devices for multiple family housing units. Such a direction was unfortunately the only way to address excessive complexity using manual design skills mainly because it was simple to conceive but also simple to construct. The unfortunate nature of this approach lies rather in the uniformity, similarity, and invariability that these projects express in comparison to individuality, discreteness, and identity that human beings and families manifest. One of the main areas of complexity that could benefit architecture is in housing projects. In these projects there is a typology of residential units that need to be combined in various schemes that will fulfill multiple functional, environmental, and economic constraints. In this paper, the design of a 200-unit residential complex on a corner of two streets in an urban context was investigated as a case study. Recent advancement in tectonics and structural engineering enables the realization of buildings in mega scales and starts to introduce another layer of complexity into the building programs. Conventional design methods relying on the preconceived knowledge based approaches are no longer reliable. Beyond the certain quantitative factors and the complexity of the problems, search occasionally enters into the unpredictable domain of the human perception. Computational approaches to design allows us to go through thousands of iterations in a second and find the solution sets beyond the reach of designers’ intuitive search spaces. Genetic Algorithm can be a potential derivative for finding optimum design solution from indeterminate search spaces constrained by multi dimensional factors.

title	Processos de design: uso de animações na concepção de peças de mobiliário [Design processes: Using computing animations for interactive furniture conception]
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 321-324
summary	This article explores the use of graphical animations in the process of furniture design. The proposals are part of the Kómuniká’tór Project (www.eesc.usp.br/nomads/ kom.htm) that investigates the insertion of media in dwelling furniture. The objective is to describe the process of creation and use of these animations pointing how this methodology has been relevant for visualizing potentials and limitations of the proposals explored in the project. Two consultations through focus groups had been carried through, the first one with potentially users and the second one with professionals of design, communication and architecture domains. The technique of animations appears as a valid method for a first contact between the proposed object with its possible user.

summary	Architects trying to promote design decisions to clients are faced with the dilemma of not having definite arguments that would convince clients of taking the right decision. Especially on urban design projects architects are faced with various contradicting wishes of citizens that most of the times is very difficult to justify. The paper exemplifies such a case where the architects had to invent a technique based on the theories of space syntax to help the municipality authorities to evaluate the design of a proposed urban park.
