title	Architecture as Drawing, Perception and Cognition

summary	This work is about realizing that human perception is inherent to architecture. It is an asset and a trait subject to training and development in an empirical way, involving physical and manual action. It cannot be taught literally through convention and logic reasoning. It is a human achievement of great significance built on intellectual and scientific knowledge. It is something, being physical and empirical, that is supported on instrumental procedure. The computer, as a machine and an instrument, does not shorten the empirical experience of manipulation; on the contrary, it enhances J.J. Gibson’s findings about the perception of space in relation to eye and body movement. Being a cybernetic machine the computer may, and shall, evolve, and become perceptive. In order for that to happen, it is important to keep in mind the mechanism of human perception. Through producing a computerized model of a major architectural work, we develop natural knowledge about its physical features and the thought that lies underneath. To be able to use the computer as an instrument provides a user with explicit knowledge about its ways and mechanism that has to be made available. It involves training, which is to a great extent self-explanatory, and also explicit knowledge about the conventions that are being used, such as programming, reasoning and trigonometry.

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	Evaluating Workflow and Modeling Strategies of Pen Computing in the Beginning Architectural Design Studio
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 163-170

summary	This paper investigates the impact of Tablet PCs on the workflow in an undergraduate design studio. We examined how well the students adapted the Tablet PC into their day-to-day design work and evaluated the appropriateness of the Tablet PC as a common digital tool used in an architectural design studio. This research involved observation of student behavior during the semester and the conducting of a survey measuring various aspects of the students’ use of the computers. A more specific goal was to compare the effectiveness of the pen versus the mouse as input devices for a three-dimensional modeling task in terms of both task time and strategies. Our assumption was that a change in input mode would affect the strategies and the performance. The results of a within-subjects, repeated-measures experiment carried out to elicit differences in input devices are discussed.

title	A Representation Language for a Prototype CAD Tool for Intelligent Rooms
source	Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 170-183
doi	https://doi.org/10.52842/conf.acadia.2005.170
summary	Intelligent rooms are a type of intelligent environment which enhance ordinary activities within the confines of a room by responding to human interaction using pervasive and ubiquitous computing. In the design of intelligent rooms, the specification of how the intelligent room enacts intelligent behavior through computational means is as integral as the geometric description. The self-aware and context-aware capabilities of intelligent rooms extend the requirements for computer-aided design tools beyond 3D modeling of objects. This article presents a Hardware as Agents Description Language for Intelligent Rooms (HADLIR) to model hardware in an intelligent room as “hardware agents” having sensor and/or effector modalities with rules and goals. End-users describe intelligent room hardware as agents based on the HADLIR representation and write agent rules and goals in Jess for each hardware component. This HADLIR agent description and the requisite software sensors/effectors constitute “hardware agents” which are instantiated into a multi-agent society software environment. The society is then bridged to either a virtual environment to prototype the intelligent room or to microelectronic controllers to implement a physical intelligent room. The integration illustrates how the HADLIR representation assists in the design, simulation and implementation of an intelligent room and provides a foundation technology for CAD tools for the creation of intelligent rooms.

summary	The research paper exemplifies a novel information integrated design technique developed at ONL (Oosterhuis and Lenard), Netherlands, specifically appropriated for envisaging 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 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-wireframes, 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	DecoSketch – Towards Calligraphic Approaches to Interior Design
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 665-670
doi	https://doi.org/10.52842/conf.ecaade.2005.665
summary	Computer-Aided Design tools have long played an important role in architecture design. However, we need to go beyond direct manipulation to devise new tools that will expedite the interior design and decoration. Indeed, conventional CAD systems, while providing ever increasing functionality, do not provide equal support to the drafting and drawing tasks. This makes even the simplest drawings a complicated endeavor. Draftspeople struggle with different concepts that those learnt from their earlier days in school and have to think long and hard to translate familiar sequences of operations to commands which require navigating a dense jungle of menus. The term calligraphic interfaces was coined by us to designate a large family of applications organized around the drawing paradigm, using a digital stylus and a tablet-and-screen combination as seen most recently in Tablet PCs®. Using these, users can enter drawings in a natural manner, largely evocative of drafting techniques that were perfected for pencil-and-paper media. This paper presents a simple calligraphic interface to explore interior design literally from the ground up. The Decosketch application is a modeling and visualization tool structured around 2 _D architectural plants. Its purpose is to help architects or customers easily creating and navigating through house designs starting from the floorplan and moving to their three-dimensional representation. Moreover, both 2D and 3D representations can be independently edited, providing a natural interface that tries to adhere to well-known representations and idioms used by architects when drafting using pencil and paper.

title	Digitally Documenting D-Day: The use of Close Range Digital Photogrammetry at Pointe du Hoc
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 634-639
summary	This paper describes the progress of a multi-disciplinary team from Texas A&M University to digitally document the command post at one of the most significant historic sites of the D-Day landings: Pointe du Hoc. The methods used to collect survey data for both the production of 2D Historic American Building Survey drawings and for the 3D digital model are described. The processes used to produce the 3D digital model involves collecting survey data using digital photogrammetry and then applying surfaces to that model using modeling software. The results of the first season’s survey work are described and illustrated. Finally, the problems encountered with lighting and the digital photogrammetry processing are discussed and recommendations made for future work.

title	Multi-user virtual worlds: 3D interactive visualization in synthetic environments for design workshops
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 344-349
summary	The goal of this research is to describe a methodology of architectural design by using digital technology with three-dimensional interactive simulation in multi-user virtual worlds. In addition, this study will focus on the application of this method in the workshops at the School of Architecture in the University of Zulia. With this proposal, it is possible to integrate many users, in real time, from different locations on the same virtual world in Internet. In the same way, each visitor is able to interact and modify the virtual world using virtual menus while sharing ideas or modifications regarding the design of the project. This strategy allows modeling, visualizing, developing and evaluating the designed projects during the conceptual and parametric phase in the process of design. This application is a powerful tool to develop creativity and skills of spatial perception among the students. [Full paper in Spanish]

source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 603-608
summary	This paper presents the advancements of the Urbamedia project which was designed as part of a research program at the Center CAO (Creation computer assist), School of Architectural Design and Urbanism, University of Buenos Aires, which was led by the valued master and advisory professor Architect Arturo F. Montagu. This proposal of the city of Buenos Aires on the Mayo Avenue expands the original historical fragment presented between the following two referenced representative landmarks: The Two Congresses Square and the Mayo Square. It continues with the advancement of methodologies and techniques implemented in a system of “integrated visualization and communication” for the development of a VRML (Virtual Reality Modeling Language) 3D virtual non-immersive and interactive vision. It also incorporates the development of a “foundation of digitally integrated knowledge” with fragments of central areas from other surrounding cities as well as interfaced phenomenological situations. The application of digital VRML technology has allowed for thoroughly researching the processes through dynamic simulation of specific urban fragments (Mayo Avenue within Buenos Aires) and the cities that are also participating in the project.

title	A 3D Model of the Inner City of Beijing
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. 63-72
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.

title	The Generation of Superstructure Geometry in Latina Temples: A Hybrid Approach

doi	https://doi.org/10.52842/conf.ecaade.2005.483
summary	The Nâgara tradition of temple building created a rich corpus of Latina (single-spired) temples spread across Northern India between the fifth and thirteenth centuries. Computing methods offer a distinct methodology for reconstructing the genesis and evolution of geometry in this tradition over time. This paper reports a hybrid technique, comprising three distinct computations for recovering and explaining the geometry of temples. The application of the technique enables scholars to bring together fragments of evidence, construe “best-fit” strategies and unearth implicit or hidden relationships. The advantage of this approach is that changes in assumptions and testing of geometric alternatives can be easily simulated from multiple sources of information, such as texts, sacred diagrams and individual temples.

title	HYBRID MODELING: MANUAL AND DIGITAL MEDIA IN THE FIRST STEPS OF THE DESIGN PROCESS
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 819-827
doi	https://doi.org/10.52842/conf.ecaade.2005.819
summary	This paper proposes a new paradigm in computer-aided design: hybrid modeling. Considering, on one hand the traditional sketches and mock-ups, and digital techniques on the other, this paradigm fuses the two and proposes a new technique that uses the performance of the digital with the capacities of the analog without replacing or imitating one or the other. In the development of design computer solutions, it is important to know the user well. However, most researchers propose systems that do not consider how designers actually work. Furthermore, two principal elements must be considered in the design process: shape and space. These aspects need to be approached with convenient tools that are adapted to the designers. This new paradigm is presented through two new innovative techniques: the hybrid mock-up (for shape) and drafted virtual reality (for space). A review of the implications of this paradigm on the design process is presented. Not only are the techniques fast and easy to learn and execute, but the results demonstrate that the designers can express both their individuality and the idiosyncrasies of their personal representations; important elements that are difficult to achieve with conventional 3D modeling techniques, especially during the primary stages of the design process.

doi	https://doi.org/10.52842/conf.ecaade.2005.467
summary	This paper presents research in computer modeling that ARIAM team of the school of architecture of Paris La Villette has been developing for several years. One of the aims of this research group is to develop computer systems that assist architects in modeling existing buildings or monuments from heterogeneous documents or data as drawings plans, sections, photos, measures taken on site etc. In spite of advances in computer recognition it’s a long way to have a system that could automatically recognize, from any bitmap document or photo, relevant architectural objects and automatically build the model these documents represent. However, if we could define a knowledge base about a particular domain, it would be possible to develop a system that could interpret specific documents that represent some kind of building or monuments. But, even in such limited domain, it is difficult to build an exhaustive knowledge base and user-interactions are generally required. We argue that a user could mark relevant information on the documents and thus facilitate the process of interpreting. The system we propose has three components: a graphical user interaction tool, an analyzer of documents and user interactions, and a generative tool that produces the required model. As an illustration, the paper presents a system we have developed which assists an architect in modeling a 3D mesh of gothic vaults for a finite elements analysis.

title	DESKTOP VIRTUAL ENVIRONMENTS IN CONSTRUCTION EDUCATION
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 725-730
summary	In construction science, classroom oriented education remains the preferred mode of teaching. Alternative methods such as field trips, use of 3D drawings, and physical models often supplement and enhance the understanding of students. In addition to the risks involved with field trips, designated sites may not be at the particular stage of construction during the academic semester, or the construction sequence may not be fast enough to demonstrate the multiple facets during field visits. Considerable pedagogical advantages can be achieved by the integration of IT and visualization tools in teaching construction engineering/technology. The objective of this research was to develop a desktop virtual environment using 3D, animations, virtual reality and walkthrough of construction processes of steel, concrete, and lightwood structures. These visualization techniques can be valuable aids not only in teaching in the classroom but also an effective self-directed tool for open learning via the web.

title	From CAD to VR – Implementations for Urban Planning and Building Design
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 399-405
doi	https://doi.org/10.52842/conf.ecaade.2005.399
summary	At present time, three-dimensional objects are often represented with 2D-data in urban planning and building design. In order to get all the involved parties to fully understand a certain project, this may not be enough. More and more projects therefore take use of the Virtual Reality (VR) technique as a complement to traditional 2D drawings and sketches. All the involved parties can then share a common frame of reference for all discussions regarding a certain project. Unfortunately, the technique is not yet adapted to fit the current building design process. In this paper, we present a solution for semi-automatic generation of a VR-model based on 3D CAD information and aerial photos obtained from the City Planning Authorities in Sweden. The data is imported to support real-time editing of terrain, roads and buildings. We also present a framework for importing 3D-models created in Autodesk Revit which enables a seamless integration of modern 3D CAD and VR-models. The features are implemented in a software developed at Chalmers Visualization studio (Gothenburg, Sweden) and technical details about terrain handling and speed-up techniques will be given.

title	Definition of a Method of Limits of the Simplification of a Hall Model in a CAD System to Diminish Falsification of Acoustic Simulation Results
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 695-704
doi	https://doi.org/10.52842/conf.ecaade.2005.695
summary	During the modelling, because of the sometimes complex architectural shape of halls, we were forced to introduce simplifications in order to carry out calculations and simulation operations on these halls, as the calculation software requires plane surfaces. This paper presents a developed tool adapted on a CAD modelling system (AutoCAD), which defines an “average limits” of the model simplification operation in order to control and diminish the falsification of calculation and simulation results on this model, such as the architectural acoustic simulation. The process of the elaboration and the adjustment of the simplified models of the Grand Theatre of Bordeaux (GTB) based on acoustical measurements and their calculation results are described in detail in a previous article (Kouzeleas and Semidor, 2001). The analysis process of the consequences of the hall model simplification on the acoustical simulation results and the applied simplification methods are described in a PhD thesis (Kouzeleas, 2002). This article is based on this analysis process in order to apply it on several simplified models of the Amphitheatre of the Architecture School of Bordeaux (Amphi- EAPB). The comparison in a CAD system (AutoCAD) of the acoustical calculation results and the areas after simplification of the simplified models of these two halls made with AutoCAD, via the developed tool adapted on the AutoCAD, permit to define a “limits average of a hall model simplification” before the falsification of these calculation results.

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. 281-290
summary	This paper presents a 24 degree of freedom input device for 3D modeling. iSphere uses the proximity information of pulling-out and pressing-in capacitive sensors to manipulate 12 control points of a 3D surface simultaneously . The iSphere dodecahedron is demonstrated manipulating an analog parametric model with high-level modeling concepts like push or pull the 3D surfaces. Our pilot experiment shows that iSphere saved many steps of selecting the control point and going through menus. Experts were used to those extra steps and still found themselves doing them but novices saved significant time for surface shaping tasks. 3D systems are benefited to execute high-level modeling commands, but lacking of fidelity is a great issue of analog input device.

title	Creating Physical Models Using Virtual Reconstructions: Mixed CAM-techniques for a Viennese Synagogue Scale-model
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 108-113
summary	In the framework of a preceding SiGraDi-conference the virtual reconstruction work of Viennese Synagogues was elaborated. The focus of this continued research project is laid on historic/reconstructive modeling, which has specific requirements towards the modeling and subsequent production of scale models. In this paper, the prerequisites of 3D-printing and lasercutting technology for model making will be presented. This includes aspects of scale and handling of individual building elements regarding the possibilities and limitations for each specific CAM-technique. Compared to the rendering models, the modeling procedures for scale-model fabrication had to be adjusted. For example, certain dimensions for details and the structural strength of 3D-printed parts have to be taken into account. Due to economical and constructional reasons as well the printing time involved, a scale-model should be created by means of mixed CAM-techniques; building components have to be split up and assigned accordingly.

summary	This paper relates to a digital architectural design experience in 2005 for the Nazca Competition. Nazca is an archaeological site situated about 400 kilometers south of Lima, Peru. It is a large desert with gigantic millenary geoglyphs carved on the surface, which can only be seen clearly from above. The Nazca geoglyphs are made up of hundreds of lines, spirals and triangular plazas, as well as zoomorphic figures like birds, fish, spider, etc. The Nazca Competition asked for an observatory-lodge of approximately 1.000m2 with 20 rooms, communal bathrooms, supporting areas and an observatory tower of at least 100 meters. The observatory-lodge was designed using a digital representation technique called "Genetically Constructed Structures". The structure was created using the geometric principle of the affinity of two conic sections: circle and ellipse. The form was produced transforming the circle and the ellipse by performing basic geometric transformations (translation, rotation, reflection and scaling). According to this technique, the sequence of transformations was codified in the form of an alphanumerical string, metaphorically named the "DNA structure". The code was inserted as extended data into the entities which shaped the structure profiles. The algorithms were programmed with AutoLISP language. The "DNA code" allowed the structure to be constructed and deconstructed from any point, generating many different forms, to be studied and compared. One year later, the same 3D model was used to test another digital technology called "musical box" where their geometrical points are captured, read and translated into musical parameters, generating music. In this paper we will present the graphical form of the tower as well as the music associated.
