title	Simulation of architectural lighting in a virtual environment - A case study on real and fake High Dynamic Range Images (HDRI)
doi	https://doi.org/10.52842/conf.ecaade.2006.566
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 566-572
summary	The early findings of this research were presented in eCAADe 2005 International Conference, Lisbon primarily to highlight the concept of High Dynamic Range Images (HDRI) when representing architectural spaces in the form of still images. An experiment had been carried out to compare the results between HDRI rendering and ‘conventional’ lighting simulation algorithms namely ray tracing and radiosity. The results were based on static and using the same exposure factors, when capturing HDRI. This project, funded by Intensification Research Priority Area (IRPA) grant continues to present and report HDRI results in a simulation environment. In this paper, we first briefly explain on the concept of real and fake HDRI. Then a comparison experiment is conducted to compare these two methods and discuss the impact and effectiveness of the illumination computation in architectural simulation environment. In order to carry out the experiment, a few models of the architectural scenes were developed. These models were then textured with real photos and manipulated with ‘shaders’, and further rendered using fake and real HDRI techniques. As for the fake HDRI, two methods were developed. The first was using an image as the ambient map and different exposures were created by increasing the value of Hue, V of HSV and saturation. The second involved a series of digital photos with the selection of the brightest and darkest area using Adobe Photoshop to establish the scale of luminosity. A few camera movements were triggered and position for ‘real-time’ rendering simulation. The result of the experiment has shown a significant improvement on the rendering time and quality of the rendering. Finally this paper suggests the selection criteria for choosing real and fake HDRI, and how each technique can be best utilized for architectural representations in a simulation environment.

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	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	NEW METHODS FOR URBAN DESIGN AND ARCHITECTURE USING THE VR TECHNIQUE AND ANALYSIS OF THE PSYCHOLOGICAL INFLUENCE
doi	https://doi.org/10.52842/conf.caadria.2006.x.p0n
source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 495-501
summary	Urban plan and architecture require the use of VR systems. We adapted the buildings into a VR system, and then performed a virtual realization in the world’s largest dome at Matsushita Electric Works, Ltd. Walking or flying through life-size space was enabled. We viewed the planned future scenes that featured real size, space composition, and a simulated environment. The construction, the materials and colors of the building were examined. In addition, VR system on PC was applied to city planning and architectural design and a number of novel functions were added to the VR system by plug-in, which assisted and facilitated the design process. The stereoscopic thinking mode in 3-D space can inspire and comprehend more directly the ideas of design, and confirm the intended effects. We accordingly carried out a further study on users operating the VR system to investigate their responses of “like” or “dislike” towards the real time adjustments of design effect at identical viewpoints. Fractals analysis was conducted to demonstrate physically the influence of real time 3-dimentional design and presentation on the psychological trends of subjective judgment. Our findings pave the way for future research on monitoring psychological impacts on observers of VR system during design process.

title	SoundScapes & Architectural Spaces - Spatial sound research in digital architectural design
doi	https://doi.org/10.52842/conf.ecaade.2006.684
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 684-689
summary	The paper presents ongoing research focusing on the development of digital tools and methodologies for spatial design based on non-Euclidean geometries. It addresses the way sound can be used both conceptually and acoustically in the early stages of the design process, examining digital architectural design and modeling based on three-dimensional sound visualization and the acoustical analysis and evaluation of complex curved surface geometry. The paper describes SoundMatrix, the first part of a digital design tool created by using Max/Msp/Jitter, to assist in the preliminary design of building façades in small-scale urban environments, specifically studying the possibilities of curvature to decrease sound reflection between opposing street façades. Examples from a workshop with the SoundMatrix application illustrate the real-time 3D authoring and sound spatialisation processing currently implemented in the tool.

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.

title	Research on New Residential Areas Using GIS - A case study

summary	Planning is a decision-making process which is about 'the future'. In each scale of planning process, spatial rules of the social life are formed. In this process, firstly series of spatial analyses should be practised. Throughout the world, spatial planning strategies which focus on the sustainable development adapt an ecological approach and both the regional and urban planning processes are based upon ecological bases. Under the guidance of this notion, also in Turkey, spatial planning strategies should be urgently reviewed and any level of planning process should be directed to ecological bases. Furthermore, in all these steps, natural resources and ecological characteristics should be taken into consideration. In the city of Bartin, where Bartin River flows through, a case study has been carried out regarding the above mentioned planning strategies. The case study has three stages. These stages also frame the data, analysis and evaluation stages. In the case study, a combination of McHarg's ecological evaluation method and Kiemstedt's usage value analysis in planning has been employed. With the help of ecological analyses, in the rural areas that have not been settled yet, the potential of the natural resources has been examined for the new residential areas. As a result, in the city of Bartin, the potential residential areas have been defined on the unsettled regions. What is more, concerning the subject, a map has been formed on the scale of 1/25 000. As a result of the case study, it has been concluded that in Bartin city because of the physical planning which ignores the potential of the natural resources, some of the existing residential areas have been chosen improperly.

doi	https://doi.org/10.52842/conf.caadria.2006.x.s8b
source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 601-603
summary	Context awareness is important for human senses of places as well as human computer interaction. The aim of this research paper is focusing on controlling the user's privacy in a smart space which is adaptive to different users for enhancing the user's awareness in his diary life. In Environmental Psychology, the definition of privacy is that an individual has the control of deciding what information of himself is released to others, and under how he interact with others. (Westin 1970) And privacy is categorized as the linguistic privacy and visual privacy. (Sundstorm 1986). Solutions for privacy control: Plan Layout, Vision Boundary, Access Control and Architecture Metaphor - the transmission of information is not ascertainable for every single user. Although information are shown in public, but information is implied by cues and symbols. Only a certain user or a group of users have access to the full context of information. The methodology is to form an analytic framework to study the relationship between information, user and activities by using the computational supports derived from KitchenSense, ConceptNet, Python, 3d Studio Max and Flash; and to record patterns built up by users' behaviour and actions. Furthermore, the scenario-based simulation can envision the real world conditions by adding interfaces for enhancing user awareness.

summary	Gaming software has a history of fostering development of economical and creative methods to deal with hardware limitations. Traditionally the visual representation of gaming software has been a poor offspring of high-end visualization. In a twist of irony, this paper proposes that game production software leads the way into a new era of physical digital ornament. The toolbox of the rendering engine evolved rapidly between 1974-1985 and it is still today, 20 years later the main component of all visualization programs. The development of the bump map is of particular interest; its evolution into a physical displacement map provides untold opportunities of the appropriation of the 2D image to a physical 3D object.To expose the creative potential of the displacement map, a wide scope of existing displacement usage has been identified: Top2maya is a scientific appropriation, Caruso St John Architects an architectural precedent and Tord Boonje’s use of 2D digital pattern provides us with an artistic production precedent. Current gaming technologies give us an indication of how the resolution of displacement is set to enter an unprecedented level of geometric detail. As modernity was inspired by the machine age, we should be led by current technological advancement and appropriate its usage. It is about a move away from the simplification of structure and form to one that deals with the real possibilities of expanding the dialogue of surface topology. Digital Ornament is a kinetic process rather than static, its intentions lie in returning the choice of bespoke materials back to the Architect, Designer and Artist.

title	Evolving Urban Structures using Computational Optimisation
source	Proceedings of the Generative Arts conference, Milan, 2006
summary	This paper investigates the use of computer analogies for naturally inspired optimisation techniques as an aid to developing the site layout and massing for the new World Trade Centre development in Pristina Kosovo, which is being designed and developed by 4M Group architectural company, in conjunction with the Advanced Modelling Group Aedas. The development of a genetic algorithm will incorporate various techniques, that have been developed in the field of multi-objective optimisation, to create three dimensional massing models, and site layout solutions which partially fulfil the Prisina brief requirements, which are taken from specifications created by 4M Group. Genetic algorithms are based on natural evolutionary principles which are explained in this paper. It will incorporate Pareto concepts to manage the optimisation of the various objective functions. For example, these will include volume and position of units, which will ensure that the different and sometime conflicting needs of the site are balanced throughout the optimisation. This type of problem is often known as an NP-complete (non-determinate polynomial time) problem. This will provide architects and planners with a number of Pareto optimised site massing solutions as an aid to the design process. An initial investigation into the specifics of the Pristina site requirements, will be followed by an investigation into the the genetic algorithm which is created in Visual Basic for Applications (VBA) linked with AutoCAD as the graphical output of the code. The embryology (development) of the various solutions from the genetic information incorporates an ‘ant’ pheromone trail model, which simulates the action of ants during food foraging, as a tool for initial route planning within the site. Diffusion and cellular automata are used during the development of the solution to construct the massing for the site.

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	The Constructed Image
source	Cheng R and Tripeny PJ (eds) Getting Real: Design Ethos Now, Proceedings of the 94th Annual Meeting of the Association of Collegiate Schools of Architecture, Salt Lake City, March 2006, 529-536
summary	Rendering engines produce ever higher degrees of photorealism, and the process of image-making becomes increasingly automated. Architects benefit from this, but they also pay a price. They exchange local control at the tip of a pencil for global control through a list of variables. They exchange the incremental build-up of line and tone for the fast calculation of summative snapshots. This paper argues that the loss of local and incremental image control necessarily leads to an erosion of visual literacy. Lacking this control, students do not practice the close scrutiny needed to develop a critical eye. To combat this, students should be taught to combine the local and the global, the incremental and the summative. A series of teaching exercises are presented that seek a better balance between automation and human influence. Rather than resisting the digital medium, the exercises explore methods of teaching visual scrutiny within the digital medium. Students learn to see the flaws in computer-generated images, and they correct the flaws with local and incremental changes. Armed with the principle of the constructed image, students regain some control of the image-making process and use it to expressive ends, but an adjusted pedagogy is not sufficient. As long as software engineers prefer to make tools that automate human effort rather than augment it, architects will lack vital image control. The concept of the constructed image is needed not only to teach visual literacy in the digital age, but to focus the fight for more appropriate tools.

title	Ethics of Virtuality… Virtuality of Ethics
doi	https://doi.org/10.52842/conf.ecaade.2006.032
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 32-39
summary	This paper addresses issues pertaining to architecture, virtuality and ethics by establishing an interactive, non-linear virtual environment as a tool for investigation into the virtuality of ethics and ethics of virtuality, in the context of architecture. Starting from the assertion that ‘Virtual Environment (VE) is a metaphor of Real Environment (RE)’, we test the proposition that suggests ‘Ethics of RE can be tested and simulated in VE’. Challenging the notion that sees people reacting to VE in the same way as they interact with their surroundings in RE, we propose that since ethics are engulfing architecture they are also present and simulated in VE. Virtual architecture has elements of ethics that we refer to as ‘Ethics of Virtuality’. In this context, VE ethics seem to lose the ubiquity that is present in RE. In order to examine this hypothesis, we created a VE that corresponds to the RE of the PhD students’ offices, within the Department of Architecture, School of Arts, Culture, and Environment in the University of Edinburgh. The real life users of these offices were subjected to this VE. A qualitative method of research followed to probe their experience, focusing on issues related to ethics. Subjects were asked to give a personal accounts of their experience which gave us an insight into how they think. The compiled list of results and their evaluation showed startling possibilities, further establishing VE as an arena for investigating issues pertaining to both architecture and ethics.

title	Diretrizez Geométricas de Auxílio ao Processo de Projeto de Edifícios Residenciais [Geometrical Guidelines to Aid the Design of Floor Plants of Residential Buildings]
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 243-247
summary	This paper discusses the basic principles of a geometric method to aid the design process of residential buildings. It makes part of the initial phases of a research whose aim is to develop a computer system to aid the sketching and evaluation of floor plant design of multi-storied residential buildings. The fundamental idea of the research is the existence of some basic patterns of floor plants that reflect the designer’s mental models in this category of building. The models are regarding the usage of the space such as forms and dimensions, the elements for the circulation and the external skins. During the design process, architects work on each one of these models to generate the sketches of the floor plant layout. Generally, the layout of an apartment in multi-storied buildings depends basically on the internal dynamics of the users without the complex relationship with the neighborhood environment as in the case of houses. In this way, it would be easier to identify, to organize and to associate the mental models of multi-storied buildings on geometric basis, which, in their turns, might be effectively used as inputs for the layout planning of new design. By applying the geometric basis, the architects may reduce the universe of feasible alternatives into a small group of heuristic solutions that can be described by using few simple guidelines. In addition to this, the geometric bases of the existing buildings might be used to build a knowledge-based system to aid the architectural design. The objective of this paper is to show some initial results of the research obtained from a survey and the case studies of form, dimensions and topology of existing buildings. To limit the scope of the discussion, only residential buildings with two to three bedrooms are considered. At first, a survey of plants of residential buildings with two and three bedrooms, in Brazil, is carried out. In the next step, the dimensions, shape, external skin perimeter, circulation system and accessibility are analyzed. Finally, typical topologies of the building are investigated.

title	A Constraint-Based Building Bulk Design Support
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 278-282
summary	We introduce an architecture practice-oriented implementation strategy of constraint-based methods called BDS (Building Bulk Design Support) to supporting bulk analysis during the architectural programming phase. We examine the optmization problem of site coverage and building massing according to a set of standard planning and zoning regulations, and try a problem solving approach based on the paradigm of constraint satisfaction problems. The case study, which is focused on the paticipatory planning of very low-income dwellings within the Latin American context, serves as testbed for a prototypical application of the adopted methodology. The BDS constitutes a novel approach on computer-aided bulk analysis, regarding this particularly relevant context of application. In the case of participatively planned low-income housing projects, efficiency regarding time and cost of planning directly affects dwellers’ quality of life, whereas elementary programming tasks such as bulk analysis lack appropriate state-of-the-art technological support. Traditional architectural planning methods demand a large domain-specific knowledge base and skillful planners. A planning process, which is mainly driven by the formulation of planning-relevant constraints and sets of solution alternatives, suggests to avoid architects’ traditional procedure of: 1. Create an (yet not necessarily valid) instance of the eventual design solution by directly choosing specific values for its shape parameters. 2. Evaluate its validity by confronting the designed model to a set of applicable constraints, which have to be satisfied. Instead, the constraint-based design methodology poses a search procedure that operates in a space of pertinent constraint sets. A computer-aided interactive search procedure to find more valid design solution alternatives in less time and with less effort is particularly qualified to supply efficient support for participatory planning activities carried out between dwellers and planners. The set of solutions for a building-bulk design problem is constrained by both a large complex system of planning and zoning regulations and the geometry of the eventual design solution itself. Given a considerable amount of such regulations, a regular size geometric constraint satisfaction system proved to be capable of providing a highly efficient, interactive modeling and evaluation tool for the formulation in real time of valid solution alternatives for an ordinary building-bulk design problem. A BDS implementation will constitute one system module of a larger integrated system model called Esther. A BDS tool shall interact with other functional modules, like e.g. the FLS (Floor plan Layout Support), which also uses constraint-based design methods.

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 this research, a close-range view expression method used in real-time simulation based on virtual reality technology is developed for environmental design evaluation. After describing the purpose and accuracy of representation, the problem of natural element representation in a close-range view, which has not been developed yet, is clarified. Next, the close-range view expression method of shadows, grass, and water surface is developed. Furthermore, the developed method is applied to a number of actual environmental design projects, and frame rate measurement and user evaluation are performed.

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.
