title	Procedural Design of Urban Open Spaces

source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 351-358
summary	This paper presents a novel approach for the automatic creation of vegetation scenarios in real or virtual 3D cities in order to simplify the complex design process and time consuming modeling tasks in urban landscape planning. We introduce shape grammars as a practical tool for the rule-based generation of urban open spaces. The automatically generated designs can be used for pre-visualization, master planning, guided design variation and digital content creation in general (e.g. for the entertainment industry). In a first step, we extend the CGA shape grammar by Müller et al. (2006) with urban planning operations. In a second step, we employ the possibilities of shape grammars to encode design patterns (Alexander et al., 1977). Therefore, we propose several examples of design patterns allowing for an intuitive high-level placement of objects common in urban open spaces (e.g. plants). Furthermore, arbitrary interactions between distinct instances of the vegetation and the urban environment can be encoded. With the resulting system, the designer can efficiently vegetate landscape and city parks, alleys, gardens, patios and even single buildings by applying the corresponding shape grammar rules. Our results demonstrate the procedural design process on two practical example scenarios, each one covering a different scale and different contexts of planning. The first example illustrates a derivation of the Garden of Versailles and the second example describes the usage of high-level rule sets to generate a suburbia model.

title	An Analysis of the Applications of Rapid Prototyping in Architecture
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	Rapid prototyping (RP) techniques are widely used within the design/manufacturing industry and are well established in manufacturing industry. These digital techniques offer quick and accurate prototypes with relatively low cost when we require exact likeness to a particular scale and detail. 3D modeling of buildings on CAD-systems in the AEC sector is now becoming more popular and becoming widely used practice as the higher efficiency of working with computers is being recognized. However the building of scaled physical representations is still performed manually, which generally requires a high amount of time. Complex post-modernist building forms are more faithfully and easily represented in a solid visualization form, than they could be using traditional model making methods. Using RP within the engineering community has given the users the possibility to communicate and visualize designs with greater ease with the clients and capture any error within the CAD design at an early stage of the project or product lifecycle. In this paper, the application of RP in architecture is reviewed and the possibilities of modeling architectural models are explored. A methodology of developing rapid prototypes with 3D CAD models using methods of solid freeform manufacturing in particular Fused Deposition Modeling (FDM) is presented and compared against traditional model making methods. An economical analysis is presented and discussed using a case study and the potential of applying RP techniques to architectural models is discussed.

title	An Intuitive Interface for Building Management and Planning
source	International Journal of Architectural Computing vol. 4 - no. 2, 17-26
summary	Building management and planning professionals utilize database systems for administrative support, but these systems are inadequate for conveying architectural plans. In this article we describe the so-called Virtual Maquette that was developed at the Eindhoven University of Technology for the board of the University. The Virtual Maquette consists of a vertical display for 3D view and information of building stock, and an interactive horizontal display for manipulation of view and information. Interaction is implemented using infrared tracking of devices that are positioned on the desktop with the projected plan view. Through this interface the states of the buildings can be inspected at different periods in history and in the future. The support of multiple devices in a single environment is a technical challenge, but it provides a new interaction method for non-technical persons.

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	Towards a Sketching Tool for Architects: 3D Reconstruction of Polyhedron
doi	https://doi.org/10.52842/conf.ecaade.2006.132
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 132-135
summary	This paper presents a tool for assisting 3D modeling from perspective projections. The proposed system uses a projective geometry engine capable of rebuilding a 3D model from a set of lines and geometric constraints. A dialogue interface assists the user in expressing geometric constraints. The system finds out the relevant geometrical components in the sketch and automatically posts the constraints. The system is limited to rebuilding polyhedrons. If we can deduce, from a perspective sketch of a polyhedron, the planar constraints of the faces and the parallelism constraints of the edges that meet in the same vanishing points, the geometric engine will be able to build a 3D model of the polyhedron.

title	“Flatness” through Camera The Implications of Camera Movement in the Digital Reconstruction of Diamond Museum
doi	https://doi.org/10.52842/conf.acadia.2006.270
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 270-277
summary	In architectural design, explorations using digital modeling and rendering tools do not stop at producing 3D geometries and representations. We need to interrogate the spatial implications of the functions these tools provide. One of the questions we need to ask is, is it possible to foreground architectural concepts “within” the mechanisms of these tools? This study focuses on one single function in 3D VIZ camera movement. The objective is to examine the spatial implications of this function in the computerized architectural space of Diamond Museum. Camera movement is studied in six variables: distance, point of view, camera angle, framing, duration and travel speed and sequencing. Further, the architectural concept of flatness will be understood through the movies generated within the space of Diamond Museum.

summary	The following paper will articulate through an urban renewal proposal project for an area in Montréal, Canada that uses a “3D imaging and modeling protocol” and that accounts for the interaction between mediation and making in digitizing and constructing existing conditions digital artifacts. The protocol incorporates multi-sensor technologies with modeling and rendering techniques through a process of interpolation between a heterogeneous set of existing photographic, physical, and 2D documentation. The mode of operation implemented is a multi-layered and hybrid approach that recognizes the interplay between human scale and perception, visualization and abstraction of data and geometric accuracy, space and time.

title	Self-Organizing Map and Axial Spatial Arrangement: Topological Mapping of Alternative Designs
doi	https://doi.org/10.52842/conf.acadia.2006.342
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 342-355
summary	This research attempts to formulate a computational framework for exploring spatial arrangements in the early phases of design. In the physical world, this could be compared to exploring spatial arrangements using cardboard cut-outs or simply a grid of spaces on paper. This research demonstrates the framework by means of a generative design system that introduces axial order in a plan parti made up of discrete 3D objects. The tool is designed to organize the 3D objects along an Axis specified by the user and also rearrange them following user-defined mathematical expressions. The numerical parameters (the dimensions and physical properties of the individual objects) are linked through the mathematical expressions to vary the spatial arrangement of objects. Implementation of the tool involves the Self Organizing Maps (SOMs) as the Graphical User Interface (GUI) in generative systems. This allows the user to select and dynamically view spatial arrangements that have been organized on a map based on their similarity. The application is implemented, tested, and its results are demonstrated using buildings designed by Louis I. Kahn, Frank Lloyd Wright and Mies van der Rohe.

summary	The purpose of this paper is to present the characteristics of laser scanning technology, based on two examples for the modeling at the reconstruction of the Golgotha site in Jerusalem and the ancient Stoa of Eumenes II, located at the South Slope of the Athens Acropolis. Terrestrial 3D laser scanning is a new methodology for three dimensional object modeling. Especially, the reconstruction of the ancient Stoa of Eumenes II comprises one of the most important restoration programs of the Greek Ministry of Culture. This paper will focus on the main steps of the laser scanning processing chain, starting from the acquisition of the data and ending with the evaluation of the 3D models.

title	The Digital Ornament using CAAD/CAAM Technologies
source	International Journal of Architectural Computing vol. 4 - no. 1, 33-49
summary	New digital technologies are challenging the traditions of the architectural design methodology, the relationship between context and design, and the dependency on skilled workmanship for the fabrication of beautiful and complex architecture. Intellectually, applications of digital technologies are also allowing for the reinvestigation, reinterpretation, and redevelopment of historical concepts, theories, and skills[1]. Our focus of ornament in this paper is presented as a constrained architectural testing ground, a reduced issue that still addresses the primary issues of geometry, aesthetics, individualism, and the transferal of design to materiality. Our work on digital ornament combines the traditionally intuitive skills of geometric & graphic manipulations with easily edited input (variables and digital images), control through parametric programming, and automated output (CNC manufacturing). The combination of these processes allows for efficient diversity and uniqueness of design, while also compensating for the increasing cost and declining availability of skilled artisans for the physical fabrication. The presented projects in teaching, research, and professional activities demonstrate our ongoing experiments with new technologies of programmed surface modeling and computer numerically controlled manufacturing (CNC manufacturing). This work has been incorporated in real world projects, both in the revitalization historic buildings, and in new applications of ornament in contemporary architecture.

title	DESIGNWORLD: AN AUGMENTED 3D VIRTUAL WORLD FOR MULTIDISCIPLINARY, COLLABORATIVE DESIGN
doi	https://doi.org/10.52842/conf.caadria.2006.x.g2k
source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 133-142
summary	Large design projects, such as those in the AEC domain, involve collaboration between designers from many different design disciplines in varying locations. Existing tools for developing and documenting designs of buildings and other artifacts tend to focus on supporting a single user from a single discipline. This paper introduces DesignWorld, a prototype system for enabling collaboration between designers from different disciplines who may be in different physical locations. DesignWorld consists of a 3D virtual world augmented with a number of web-based communication and design tools. DesignWorld uses agent technology to maintain different views of a single design in order to support multidisciplinary collaboration and address issues such as multiple representations of objects, versioning, ownership and relationships between objects from different disciplines.

source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 618-625
summary	In next-generation networking environments, ubiquitous networks will be available both indoors and outdoors. Various devices will be ubiquitously embedded in the surrounding environment, such as buildings and urban spaces. We will be able to browse digital contents on ubiquitous networks anywhere and at anytime. In our research, we have proposed several content-processing mechanisms for use in environment-enabled collaborative acquisition of embedded digital content in the real world situations. We have developed a network management device that makes it possible to acquire embedded content using coordinated ubiquitous devices. We have also developed two prototype systems using these devices. In this paper, we describe the implementation of a prototype system that can share 3D objects in a virtual 3D space based on a real-space environment. This system can be used not only as a virtual 3D browser in a private area, but also as an interactive digital poster in a public area. We tested our system in real situation, and explore the feasibility of applying our system in a ubiquitous environment.

title	Testing 3D Building Modelling Framework In Building Renovation
doi	https://doi.org/10.52842/conf.ecaade.2006.268
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 268-275
summary	The paper describes a process where digital measuring survey data is transferred into 3D building model to be used as a foundation for renovation design. The process and method is tested in a case study of an office building of 8 floors. Measuring survey data is more often documented to 2D plan drawings, whereas 3D-modelling was more preferable in the case project. The final aim of the case project is to further test building product model or building information model (BIM) based design methods in building renovation. Product modelling is one emerging framework to manage building related information in contemporary design & construction. Model based methods are more commonly used in new buildings, whereas renovation is usually done with more traditional techniques. Case project results underline the importance of measuring and modelling definition phase. Measuring and documenting objectives for 3D-model based design work are different than for traditional design work. Measuring survey has to be done under the coordination of the designer participants. Selecting and informing the proper and capable surveying partners is also important.

source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 758-762
summary	This paper illustrates the methodology, technological solutions and interaction metaphors chosen for the development of a 3D immersive Virtual exhibition that aims at enriching the visit of an important part of the historical cultural heritage of the city of Trento, in Italy. The goal of this work, supported by the local authority for Cultural Heritage, was to implement a user friendly virtual environment, which could show to the visitors the significance of the archeological findings of the ancient Roman town of Tridentum, despite the peculiarity of the site’s premises, located below a square among a theatre foundations. Outcomes of the research work are a high-quality and scientifically correct reconstruction of the Roman town in various historical eras, thanks to fruitful interaction with archeologists, and the development of an ad-hoc user-friendly immersive virtual environment implementing a customized interaction metaphor for the fruition of the virtual reconstruction. The developed interface allows users speaking different languages to share simultaneously the experience of virtual tours across time using a joystick. The whole environment has been developed to become a permanent virtual exhibition in the premises of the archeological site.

title	Fascination google earth – use in urban and landscape design
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 141-148
summary	Virtual 3D-City-and Architecture models, Virtual Globe systems like NASA World Wind and Google Earth as well as new attempts of immersive technologies become more important, not only among experts in spatial planning, but also many private users are interested in these new tools. These developments cause powerful impacts in the general social, cultural and everyday life. Given the dynamic development of Google Earth, the discussion about the representation and the use of geodata for a wide user group - beyond the planning disciplines - reaches new heights. According to expert's opinion, Google Earth with its computer language KML (Keyhole Markup Language) becomes a 3D-GIS-Standard [Rush in 2006]. By the easy and quick representation of three-dimensional (city) structures and single buildings, Google Earth will significantly influence all groups of society. User groups which have not been acquainted with geodata or highly specified and complex GIS-Systems [Dworschak in 2006], discover that working with this data by using Google Earth is great fun. They recognize, that with the help of generally understandable and easily recognizable visualisation of these data, mediation of knowledge becomes very easy. In addition, it is acknowledged that geodata has great potential to add value, in disciplines such as the academics, the financial sector or personal use.

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	Foundations for a Constraint-Based Floor Plan Layout Support in Participatory Planning of Low-Income Housing
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 283-287
summary	We introduce the foundations of a novel approach that deals with constraint-based design methods to supporting participatory planning processes of low-income dwellings. We examine the space allocation problem inside the architectural domain on the basis of graph theory and combinatorics, providing a concise mathematical background for an implementation strategy called FLS (Floor plan Layout Support), which is analyzed here for the first time regarding this particular context of application. The philosophy underlying a design method that is mainly driven by the formulation of distinct constraints suggests to avoid the traditional procedure of first to create a yet not necessarily valid instance of the eventual design solution by directly choosing specific parameter values of its shape, and later on to evaluate its validity by confronting the designed model to a set of applicable constraints. Instead, constraint-based design poses a search procedure that operates in a space of planning-relevant constraint sets. The FLS methodology integrates some few principles of constraint-based automated reasoning with high user interactivity, into a design environment where as much dwellers as planners can collaboratively work in solving spatial organization problems of housing projects. The FLS model of application makes use of a combination of dweller-specified constraints, planning and zoning regulations, and a small library of modular space units. Constraint-based design ! methods are particularly capable of supplying efficient support for the collaborative involvement of dwellers into the architectural programming process of her/his own home. Mainly, because dwellers themselves tend to describe their space need and design intentions as a set of constraints on room quantity, space utilization, circulation system, allocation of available furniture, available budget, construction time, and so forth. The goal is to achieve an integrated tool for finding and modelling topologically valid solutions for floor plan layout alternatives, by combining user-driven interactive procedures with automatic search and generative processes. Thus, several design alternatives can be explored in less time and with less effort than using mainstream procedures of architectural practice. A FLS implementation will constitute one system module of a larger integrated system model called Esther. A FLS tool shall interact with other functional modules, like e.g. the BDS (Building Bulk Design Support), which also uses constraint-based design methods. A preliminary procedural model for the FLS was tested on Chile’s official social housing standards (Chilean Building Code – OGUC. Art. 6.4.1) which are very similar to most Latin American housing programs currently in operation.

title	Teaching parametric design in code and construction
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 158-161
summary	Automated manufacturing processes with the ability to translate digital models into physical form promise both an increase in the complexity of what can be built, and through rapid prototyping, a possibility to experiment easily with tangible examples of the evolving design. The increasing literacy of designers in computer languages, on the other hand, offers a new range of techniques through which the models themselves might be generated. This paper reviews the results of an integrated parametric modelling and digital manufacturing workshop combining participants with a background in computer programming with those with a background in fabrication. Its aim was both to encourage collaboration in a domain that overlaps both backgrounds, as well as to explore the ways in which the two working methods naturally extend the boundaries of traditional parametric design. The types of projects chosen by the students, the working methods adopted and progress made will be discussed in light of future educational possibilities, and of the future direction of parametric tools themselves. Where standard CAD constructs isolated geometric primitives, parametric models allow the user to set up a hierarchy of relationships, deferring such details as specific dimension and sometimes quantity to a later point. Usually these are captured by a geometric schema. Many such relationships in real design however, can not be defined in terms of geometry alone. Logical operations, environmental effects such as lighting and air flow, the behaviour of people and the dynamic behaviour of materials are all essential design parameters that require other methods of definition, including the algorithm. It has been our position that the skills of the programmer are necessary in the future of design. Bentley’s Generative Components software was used as the primary vehicle for the workshop design projects. Built within the familiar Microstation framework, it enables the construction of a parametric model at a range of different interfaces, from purely graphic through to entirely code based, thus allowing the manipulation of such non-geometric, algorithmic relationships as described above. Two-dimensional laser cutting was the primary fabrication method, allowing for rapid manufacturing, and in some cases iterative physical testing. The two technologies have led in the workshop to working methods that extend the geometric schema: the first, by forcing an explicit understanding of design as procedural, and the second by encouraging physical experimentation and optimisation. The resulting projects have tended to focus on responsiveness to conditions either coded or incorporated into experimental loop. Examples will be discussed. While programming languages and geometry are universal in intent, their constraints on the design process were still notable. The default data structures of computer languages (in particular the rectangular array) replace one schema limitation with another. The indexing of data in this way is conceptually hard-wired into much of our thinking both in CAD and in code. Thankfully this can be overcome with a bit of programming, but the number of projects which have required this suggests that more intuitive, or spatial methods of data access might be developed in the future.
