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.

summary This paper describes a procedure that feeds remotely a modelling system with geographical coordinates and the relative measurements taken in place in order to model dynamically new entities in real-time. The operation of this system is based on methodologies that are commonly used in telegeoprocessing – telegeomonitoring systems and its purpose is to simulate in real-time an existing environment using the captured measurements. The direct input of geographic data to the proposed system, which is adapted to a modelling environment (CAD or GIS), triggers the creation of new 3D entities in real-time (points, linear or area features), as it could be done with a traditional tablet digitizer. Simultaneously, the proposed system represents thematically the properties of the modelling entities (according to the measured values) over a 3D mesh. The aim of the suggested system is the remote registration of additional spatial information, their adequate treatment and adjustment via special developed interfaces, including their representation via developed software which is applied in the AutoCAD environment because of its programming development support and its use by a variety of engineers.

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.

summary In recent years there has been a demand that local residents take part in the planning of environmental designs from the initial stages. On the issue of understanding the local environment, it is desirable to accumulate and share information and to enable it to be reused. To this end, attention has been focused on the cellular phone which can provide position information and picture information in addition to serving as a tool of general communication. For several years now it has been increasingly common for cellular phones to be equipped with an E-mail function, a web browsing function, a camera function, a GPS function, etc. Using such cellular phones, it will become possible to quickly accumulate local information with detailed picture information and position information. On the other hand, it is desirable to look at and understand an environment interactively from various points of view from the initial stage of a project. For that purpose, examination using 3D space which makes real-time simulation possible is required. In this research, using a cellular phone with a GPS camera, scene image data is collected with the aim of constructing a local scene evaluation system which can perform a picture display using a 3D space model.

title Digital Rectified Imagery: a survey method for design and conservation projects
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 Faced with the need for understanding the physical context of the projects that come under their jurisdiction, architects, urban designers, and conservationists strive to secure congruent information. Practicing professionals are not set to carry out the collecting of information themselves. As information “users,” they reach out to information “providers,” including surveyors, photogrammetrists, and GIS specialists, to secure needed information. Information providers employ a gamut of methods to survey and document design project contexts, including land surveying techniques, stereophotogrammetry, rectified imagery, laser scanning, and GIS. This study deals with digital rectified imagery (DRI) only and is aimed at creating an awareness of the method characteristics in the minds of the information users toward taking advantage of available DRI documentation opportunities offered by the information providers. As part of the methodology for this study, the authors have selected a subject building, captured a number of images through a digital camera, and processed the images using image processing software. The significance of this study resides in enabling the information users to understand RDI and to tap on its potential for consummating design, planning, and conservation projects.

summary As our civilization dives deeper into the information age, making sense of ever more complex and larger amounts of data becomes critical. This article reports on interdisciplinary work in Information Visualization addressing this challenge and using architectural expertise as its main engine. The goal of this research is to significantly improve real time decision making in complex data spaces while devising a new architecture that responds to complex information environments. Although we have been reporting in aspects of this work for the past 7 years, this paper covers unpublished knowledge, design methods, operational strategies, and other details that bring together all the material published by our group thus far into a comprehensive and useful whole. We conclude by presenting our latest InfoVis design work in Network Security.

title The Informed Wall: applying additive digital fabrication techniques on architecture

summary In this work in progress report we present the results of a four week design studio with graduate students as part of a broader research project on investigating digital additive fabrication processes and their implications on architectural design.In a simple test arrangement we realized the digital design and additive fabrication of two by three meters brick walls. The use of bricks, being the primary module for construction, and at a relatively coarse resolution, allowed us to concentrate on the design of completely programmed walls encompassing material-dependent parameters. The resulting prototypes depict the great potential of the integration of the design and the fabrication process. Non-standardized solutions can be easily accomplished as the design data is directly used to control the fabrication process. In using an additive digital fabrication process, a novel architectural product of the kind “brick wall” emerged, which could not have been conceived or fabricated manually.

summary Representational approaches have always played an important role in the design-driven development of built environments, the analytical study of architectural compositions and their effects. With the introduction – and successive steady development – of computer-based platforms of visualization, the professional and intellectual palette of designers, as well as researchers, have expanded considerably. Nonetheless, in recent years the opportunities for systematic scrutiny and understanding of the expressive qualities of design proposals and artefacts have all too frequently been overshadowed by high-flying conceptual developments and seductive representation modes. It is time that the objective description and unravelling of architectural compositions – so to speak the discipline of Ekphrasis in design practice, education and research – is once again given more prominence in architectural discourse and debate. The central idea behind this contribution is that, by linking instruments of design with the methods of formal composition and decomposition, renewed opportunities for representation-driven study in a scholarly context, focusing upon elusive compositional attributes and their workings, may be given a new impulse. The project that is presented here concerns a case-based explorative study into the domains of aesthetic convention and invention, making use of a variety of virtual and physical representation techniques. These include digital as well as tangible modelling and sketching approaches (separately and in combination), in conjunction with computer-based image manipulation techniques, making use of systematic data identification and denotation. The opportunities, merits and shortcomings of the computer-based and physical visualization approaches, which were applied and tested, are discussed on the basis of results and findings from the ongoing AA Variations project.

summary In 1990, due to the traditional architecture design and construction method difficult to build the complicated and non-geometry free-form Fish Structure in Barcelona, architect Frank Gehry started learn from the field of aerospace to utilize CAD/CAM technology in design and manufacture process. He created the free-form fish model in CAD system and exported the digital CAD model data to CAM machine (RP and CNC) to fabricate the design components, and finally assembled on the site. Gehry pioneered in the new digital design process in using CAD/CAM technology or so-called digital fabrication. It becomes an important issue recently as the CAD/CAM technology progressively act as the new digital design media in architectural design and construction process (Ryder et al., 2002; Kolarevic, 2003). Furthermore, in the field of architecture professional, some commercial computer systems had been developed on purpose of standardizes the digital design process in using CAD/CAM fabrication such as Gehry Technologies formed by Gehry Partners; SmartGeometry Group in Europe and Objectile proposed by Bernard Cache. Researchers in the research field like Mark Burry, Larry Sass, Branko Kolarevic, Schodek and others are enthusiastic about the exploration of the role of CAD/CAM fabrication as new design media in design process (Burry, 2002; Schodek et al., 2005; Lee, 2005).

summary This paper describes ongoing research into how emerging Internet concepts used in conjunction with existing Information Technologies (IT) can improve inter-project communication and understanding. The emphasis of the research is to use technology as an enabler to share personal thoughts and enhance the conversation that takes place within a development team. It stems from the observation that the emphasis of many new Architecture, Engineering and Construction (AEC) technologies is to minimise and diffuse project conversation with highly complex, machine interpretable building information models.Project teams are usually brought together for a relatively short but intense period of time. Following project completion these unique teams are dissolved just as quickly and often are never formed again. As a consequence it is difficult to justify the investment in time and resources required to implement complex IT-based collaboration solutions. A further barrier to adoption is the differential application of IT skills across the AEC industry. Therefore in order for a new technology to gain broad acceptance and be most beneficial it must be applicable to the broadest audience with the minimum investment required from all parties. The primary objective of this research is to preserve the rich design history of a project from conception to completion. Submitted information can be intelligently searched using the meta-data sourced from syndicated data feeds about team members, project timelines, work diaries and email communication. Once indexed users can tag documents and messages in order to provide a further, far richer layer of meta-data to assist in searching, identification of issues and semantic clarification. This strategy of defining AEC semantics through social interaction differs greatly from that of more complex, computer interpretable solutions such as Industry Foundation Classes. Rather than abstracting information to suit a generic yet highly intelligent building model, the emphasis is on preserving the participant’s own thoughts and conversation about decisions and issues in order to create a forum for intelligent conversation as the design evolves.

title Computational Derivation of Incident Irradiance on Building Facades based on Measured Global Horizontal Irradiance Data
source Vienna University of Technology; Building Science & Technology
summary Reliable simulation of buildings' energy performance requires, amongst other things, the availability of detailed information on the magnitudes of incident solar radiation on building facades. However, the availability of the measured data concerning the incident solar radiation on vertical surfaces is restricted to only few locations. In addition, concurrent measurements of horizontal global and horizontal diffuse (or direct normal) irradiance data are likewise available only for a limited number of locations. In contrast, global horizontal irradiance data is available for many locations. This research demonstrates how to computationally derive incident irradiance values on vertical (or otherwise inclined) building surfaces from measured globalirradiance values. Given this context, three methods are considered to compute incident vertical irradiance values based on measured global horizontal irradiance data. Vertical solar irradiance measurements are described. Then, the computationally derived values are compared withcorresponding measurements. The results are evaluated based on their correlation coefficients and relative error. Finally, the application of horizontal-to- vertical irradiance mapping is demonstrated using the case of an office building at Vienna University of Technology.

summary The choice of a chord and its execution should be regarded as a must and not left to arbitrary wish or superficial speculation. (Johannes Itten, 1961) The paper describes a modular concept for the IT-support of planning practice using BIM (Building Information Modelling) and a parameterized building model. The platform used is the modularized software concept for architectural planning in existing built contexts (prototype software FREAK). The current progress in the development of a reasoned support of planning tasks is described in this paper in more detail. The system consists of a series of software prototypes which are linked to the BIM, utilize the specific data within and demonstrate the value of a consistent and extendable CAD-model. The “Colored Architecture” software prototype is one such design-support module of the software platform and enables the designer to experiment with the parameters colour, light and materials in architectural space. This module supports experimentation, assessment and realization of colours and materials in the architectural design process on a new quality. For instance, the integration of “live radiosity” light simulation allows a qualified and interactive assessment and evaluation of colours and materials in near-real lighting conditions. The paper also details further software prototypes, modules and concepts including building surveying and the design of self-supporting domed structures.

summary Virtual Environments and their Interconnectivity in the Web for the Urban Planning. This work presents the creation of virtual environments based on the urban space of the Plaza Baralt in Maracaibo, Venezuela; in defined historical moments as study scenarios, using autonomous virtual agents. The selection of the scenarios is based in the analysis of the place in the present, and the study of multimedia material of the period 1920-2006. The main objective is developing virtual environments, incorporating the interconnectivity in the Web into a multi-user system, for the urban planning. Methodologically, it's divided into the following phases: 1) Data search; 2) Study of the social, cultural, religious and economical activities of the square; 3) Analysis of the urban space; 4) Virtual reconstruction of the scenarios in the present and in the period between 1900 - 1927; 5) VRML exporting ; 6) Characters' animation; 7) Integration of the models into a multi-user system; and 8) Web event for the presentation of the results.

title A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London.

title Experimenting with 3D Digitization of Architectural Physical Models using Laser Scanning Technology
source International Journal of Architectural Computing vol. 4 - no. 2, 67-80
summary This paper assesses the use of 3D Digitization techniques by carrying out laser scanning of typical physical models produced by architecture students. The aim was to examine the product of laser scanning with respect to scanning and 3D modeling processes, and the effects of variables such as characteristics of the models, materials used, and design complexity. In order to assess the similarities and accuracies achieved by the scanning and 3D modeling processes, the research investigated human perception of differences between analogue and digital models. This enabled an assessment of the degree to which digital models were accurate representations of the real ones, and whether laser scanning can successfully be used as a medium to recreate and represent complex architectural physical models. The study presents a potential direction for digital translation in architectural education.

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.

summary Mainstream communication modes emphasise network speed, connection access, resolution, portability, and aesthetic design as primary to the success of their products. Within this vision a three by four centimetre screen and high resolution display are deemed adequate to emulate the intensities and complexities of face-to-face connection with loved ones. They allow us to ‘be there with you’ from wherever we might be. Yet interpersonal communication is a massively complex phenomenon. It involves a plethora of micro-activities which occur at a physical, physiological, and psychological level allowing us to recognise at a cellular scale intention, motive and emotional authenticity. Our conscious and non-conscious involvement in spatially collocated communication is substantial due to these myriad channels of real-time bi-directional information transfer. While contemporary communications technologies have the capacity to mediate our relationships, they fall short of encouraging the richness of spatially co-present interaction. The research discussed in this paper investigates the potential expansion of remote connection when electronically enhanced apparel is incorporated into the communications mix. Rather than pursuing the manifold functionalities of traditional communications media the garments discussed focus solely on the goal of enhancing empathy between physically distant individuals. This paper reports on the development and testing of a range of garments that conduct presence information between remotely located people. The garments sense, process, transmit and receive the heartbeat wavelength (ECG). They are enabled with ECG sensors, signal processing equipment, small vibration motors, and radio transceivers which allow users to ‘feel’ the heartbeat of a remote friend/lover/relative as vibration through their garment. The prototypes aim to enrich the remote communications experience through reintroducing an embodied, tactile dimension that is present in face-to-face communication. A range of user testing trials will be discussed which have been undertaken to assess the impact of the garments at a conscious and a non-conscious level. Conscious experiences were gauged through qualitative testing, by way of interviews and unsolicited written reactions, which have provided a range of engaging emotional responses. Non-conscious physiological reactions were assessed by recording ECG throughout user-testing periods. This data has been processed using HRV (heart rate variability) analysis software, running on MatLab. Preliminary results suggest that users have strong conscious and non-conscious reactions to the experience of wearing the prototype garments. The paper will describe the data processing techniques and findings of the user testing trials. The development of biosignal sensing garments has raised a range of issues including: innovative potentials for embedded peripheral awareness media; the expansion of the classical body to incorporate remotely sensed information; the issue of data semantics and the development of intensely personal non-verbal languages; and the issue of corporeal privacy when one’s biological information is exposed for potential download. They also bring into question how our bodily experiences might change when we incorporate remote sensory systems.

summary This study explodes a domain where the use of pictures is essential [Sabrina Kacher 2002]. Designers need a way to rapidly get image. Recent years, there are more and more companies start to store and sale images for designers. They try to use hypermedia or website system to support designers when they need images.

summary To make whole one image on screens that is generated by many computers and synchronization among computers, there is a need for a network software environment for multi-projector display system. Although the development costs increase for parallel programming for multi-projector display system, there is a possibility that the program cannot be executed at an enough speed since the network bandwidth might become a bottleneck. There are some software environments for that kind of multi-projector display system like Chromium that is latest version of WireGL (Humphreys, 2001&2002). WireGL is a kind of Client-Server Model, which one rendering server sends the data of rendering to many computers. While it can use the application without modification of source, it requires heavy network traffics. The other type of operating software is VR Juggler (Cruz-Neira, 2002), and CAVE Library that is a kind of Master-Slave Model. In the Master-Slave Model, every computer has same application programs to render the image that only keep the synchronization of rendering and events. But, these programs require a specialized skill and knowledge to modify the source of program for the certain rendering PC-Cluster system.

summary In this paper we explore possibilities for using Artificial Intelligence techniques to boost the performance of urban design tools by providing large scale data analysis and inference capability. As a proof of concept experiment we showcase a novel application that learns to identify a certain type of urban setting, Main Streets, based on architectural and socioeconomic features of its vicinity. Our preliminary experimental results show the promising potential for the use of machine learning in the solving of urban planning problems.
