title	Testing 3D Building Modelling Framework In Building Renovation
doi	https://doi.org/10.52842/conf.ecaade.2006.268

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.

summary	Exploring the duality of pervasive computing and architecture in order to propose new models of interaction between people and their built environment. One of the unique "affordances" of digital media is interactivity. This word has come to stand for all manners of engagements between people and things but as McCollough (2004) reminds us the word implies deliberation over the exchange of messages. "Objects" or architecture would be exempt from this mode of communication since, in a likewise manner, we don't interact with a door, we simply open it. However, computing provides a reflexive twist for it is not only the means through which we indirectly communicate with others but also a subject with which we can directly interact. They solicit information and based on the deliberation we ask them for return responses. This quality of computing, especially as it becomes pervasive, has profound implications for architecture and urbanism. When computation becomes embedded into the very materials we build, they along with their nature as inanimate objects become questionable. Our environment itself becomes the interactive subject through which we can inquire about our condition, perform diagnostic tasks or most significantly converse to discover more about our surrounding and ourselves.

title	EL INVALORABLE APORTE DEL PIXEL AL ANÁLISIS DINÁMICO URBANO (The Invaluable Contribution of the Pixel to the Urban Dynamic Analysis)
source	SIGraDi biobio2001 - [Proceedings of the 5th Iberoamerican Congress of Digital Graphics / ISBN 956-7813-12-4] Concepcion (Chile) 21-23 november 2001, pp. 328-330
summary	Cities are growing out of control and with unforeseen complexity, with a lavish energy waste and an increasing life-quality loss. A possible approach to cope with these difficulties is the use of Urban Dynamic Analysis, a multidisciplinary body of knowledge allowing the holistic study of time-relationships between city structures and their related distinctive functions. A set of computer-aided tools is being developed following these guidelines. They are intended for the assessment of the behaviour of morphological layouts as regards to energy saving. Three such tools are described, using different pixel-counting approaches in order to simplify and facilitate their use.

title	The Digital Environment of Urban Dynamic Analysis
source	International Journal of Architectural Computing vol. 1 - no. 3
summary	Urban sprawl and complexity are increasing at an alarming rate causing huge energetic waste and affecting the quality of life of people and life on earth in general. This paper proposes Urban Dynamic Analysis as a feasible approach to address this negative phenomenon. Urban Dynamic Analysis is a multidisciplinary holistic method that inquires into temporal relations between structures and related characteristics in cities. A range of simulation tools are being adapted and developed aiming to assess different morphological configurations of urban spaces, to improve the welfare of citizens and to optimise energy consumption. All these tools are based on digital image utilization, with simple computational techniques.

title	Developing a Hybrid Intelligence Through Hacking the Machine Learning Neural Style Transfer Process for Possible Futures
doi	https://doi.org/https://doi.org/10.1007/978-981-19-8637-6_25
source	Proceedings of the 2022 DigitalFUTURES The 4st International Conference on Computational Design and Robotic Fabrication (CDRF 2022)
summary	This article highlights work using machine learning in collaboration with designers for speculative world building. The process is unique because of the feedback loop, between the designer and the computational process. Worldbuilding is a speculative practice and requires vision and courage on the part of the designer. Working with machine learning neural style transfer (NST) allows the designers to consider possibilities humanity may not otherwise allow ourselves to imagine. This is important because human imagination paves the path for the future of humankind. Imagining a sustainable future requires considering unconventional solutions. Imagining non-probable futures allows humanity to glean desirable aspects to strive for. Even if a conceived future is impossible within the built environment, there are many opportunities for people to inhabit these environments virtually. Letting yourself get lost in these places is a form of travel, even when conditions limit one's ability to physically do so.

title	A perceptually based physical error metric for realistic image synthesis
source	Alyn Rockwood, editor, SIGGRAPH 99 Conference Proceedings, Annual Conference Series, ACM SIGGRAPH, Addison Wesley
summary	We introduce a new concept for accelerating realistic image synthesis algorithms. At the core of this procedure is a novel physical error metric that correctly predicts the perceptual threshold for detecting artifacts in scene features. Built into this metric is a computational model of the human visual system's loss of sensitivity at high background illumination levels, high spatial frequencies, and high contrast levels (visual masking). An important feature of our model is that it handles the luminance-dependent processing and spatiallydependent processing independently. This allows us to precompute the expensive spatially-dependent component, making our model extremely efficient. We illustrate the utility of our procedure with global illumination algorithms used for realistic image synthesis. The expense of global illumination computations is many orders of magnitude higher than the expense of direct illumination computations and can greatly benefit by applying our perceptually based technique. Results show our method preserves visual quality while achieving significant computational gains in areas of images with high frequency texture patterns, geometric details, and lighting variations.

title	An Iterative Procedure for the Polygonal Approximation of Plane Curves
source	Computer Graphics and Image Processing. Academic Press Inc., August, 1972. vol. 1: pp. 244- 256 : ill. ; diagrams. includes bibliography
summary	The approximation of arbitrary two-dimensional curves by polygons is an important technique in image processing. For many applications, the apparent ideal procedure is to represent lines and boundaries by means of polygons with minimum number of vertices and satisfying a given fit criterion. In this paper, an approximation algorithm is presented which uses an iterative method to produce polygons with a small-but not minimum-number of vertices that lie on the given curve. The maximum distance of the curve from the approximating polygon is chosen as the fit criterion. The results obtained justify the abandonment of the minimum- vertices criterion which is computationally much more expensive

title	Digital Innovation in Architecture: Key determinants and barriers in the case of small architectural firms
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 65-84
summary	The rapid development of digital technology has made architecture a succession of different evolutionary design methodologies. As a result, the rise of computationally driven processes has gain popularity in research and shows a great potential to dramatically improve the design process and productivity that evoke innovations in design practices wherein computer-based project plays a vital role. However, as these technologies rapidly develops and increasingly used in practice, there is a realization that substantial organizational and technological barriers exist that inhibit the effective adoption of these technologies in architectural practices wherein complex projects are being handled. Undeniably it happens in small architectural practices whereby resources are very limited. Relevant literature of the subject shows that research in innovations in manufacturing, product design, technology, construction and engineering practices is substantially conducted but research in digital innovation in design practices is very limited. This paper investigates the factors that impede the effective adoption of emerging digital technologies for the efficient delivery of design projects that are computationally and digitally driven. This involves evaluating digital technologies, technical, financial and organizational barriers when digital innovation is implemented. In order to gain insights of these issues, a pilot study was conducted from several small architectural organizations, and found out relevant attributes and pattern of variables that can be used in establishing a framework for digital innovation.

summary	This research is based on the problems faced by designers in the execution of models generated with the "Form-findind" design technique, due to the low or non-existent market proposal regarding the quality of materials capable of withstanding the stresses to which a model with complex curvatures is subjected; therefore, the use of agro-industrial pozzolans (sugarcane bagasse ash) is proposed as a 20% substitute for Portland cement to obtain flexible concrete, with the intention of evaluating the physical-mechanical behavior and its application to geometries based on force systems (catenaries) obtained from mesh relaxation through digital simulation, following the form-finding technique, resulting in a 16% superiority in compression tests of concrete with pozzolans compared to conventional concrete (control).

doi	https://doi.org/10.52842/conf.ecaade.2007.359
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 359-365
summary	In the era of communication, the participation in internet-communities has grown to become a motor for innovation in software and community platforms. The paper describes the hypothesis that, by creating a virtual city (or a second city) a new type of social, economic and scientific network is established, which is supported through visual communication technologies. The various users bring, per se, their own intrinsic motivation and requirements to the system. Nonetheless, a personal identification with a city/neighbourhood/house/apartment can be used to awake awareness and to foster participation. This is especially important when dealing with the city inhabitants. City modelling itself has been carried out for over a decade. Projects such as the city model of Graz have shown how city models can be established so as to be scalable for new information (Dokonal et al 2000). Furthermore, these city models have been used in the education of future architects and urban planners. The project described here moves in the opposite direction: the model moves out of the classroom to an interdisciplinary city-model-platform. The work described here is the conceptual model for a multi-dimensional data set that models the city. This has spawned a host of other projects using the model as a foundation for further interactivity development and the extension of the model itself. The paper describes the structure of the conceptual model and the first experience of incorporating diverse projects such those mentioned above. The model also is structured so as to be compatible with the XML standards being developed for city information (CityGML). The goal of the project is to create a data set describing the city that not only describes the geometry, but also the history (including planned histories) and nature of the city. In contrast to virtual realities, which attempt to create a separate world (e.g. Second Life), the Second City is intended as an interdisciplinary repository for the geometrical, historical and cultural information of the city.

summary	Architectural discourse has recently suggested a new material practice derived from advances in the field of synthetic biology. As biological organisms can now be designed and engineered for specific purposes, it is expected that, in the near future, it will be possible to program even more complex biologically based systems. One potential application is to literally grow buildings by programming cellular organisms to fabricate and deposit material into architecturally relevant patterns. Our current design methods do not anticipate the potentially challenging material practice involved in a biologically engineered architecture, where there is a loose and emergent relationship between design and material articulation. To tackle this conflict, we developed SynthMorph, a form-finding computational tool based on basic biological morphogenetic principles. A reflection is offered on its use, discussing the effect of multicellular morphogenesis on the production of shape. We conclude that such a strategy is an adaptive design method in two ways: (a) the mechanics of design using morphological constraints involve a practice of dynamic and continuous negotiation between a design intent and material emergence, and (b) the proposed design strategy hints at the production of a biologically produced architecture, which would potentially behave as an adaptive organism.

summary	The last few years have seen an increase in the interest to bring living systems into the process of design. Work with living systems, nonetheless, presents several challenges. Aspects such as access to specialists’ labs, samples of living systems, and knowledge to conduct experiments in controlled settings become barriers which prevent designers from developing a direct, material engagement with the material. In this paper, we propose a design methodology which combines development of experiments in laboratory settings with the use of what we call material proxies, which refer to materials that operate in analogue to some of the behaviors observed in the target organism. We will propose that combining material proxies with basic scientific experimentation constitutes a form of direct material engagement, which encourages richer exploration of the design domain. We will develop this argument by reporting on our experience in designing and delivering the primer component of a themed design studio, structured around bacterial spores as hygroscopic components of building facades. The six-week design project asked students to consider the behavior of bacterial spores, and to imagine a number of systems in which they could be employed as actuators of a membrane system that responded to fluctuations in humidity. The module is interesting in that it negotiates some of the challenges often faced by designers who want to develop a material engagement with living systems, and to produce informed speculations about their potential in architectural design.

title	Do Analógico ao Digital? [From analog to digital?]
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	After admitting that the immersion of Architecture in digital environment happened in the last decade of the XX Century, this paper argues about the (im)possible links established between analogical and digital worlds. Discarding the possibility of a “transition” between them, the paper points the existence of a “jump” that, more than to tie, unlinks them leaving an emptiness that has to be analyzed. Coexisting in this emptiness we find hybrid structures of pragmatic approach, ruptures of paradigms and sprouting of new forms to project and to make architecture. Clarify this panorama is a basic task we need to do before facing the future, not only in a professional way, but also in the field of architectural education, because we have to know which architecture we desire to transmit.

title	An Architecture Model for Multimodal Interfaces with Force Feedback I.14 Virtual Reality 2
source	Proceedings of the Sixth International Conference on Human-Computer Interaction 1995 v.I. Human and Future Computing pp. 455-460
summary	Multimodal interfaces with force feedback pose new problems both in terms of their design and for hardware and software implementation. The first problem is to design and build force-feedback pointing devices that permit users both to select and manipulate interface objects (windows, menus and icons) and at the same time feel these objects with force and precision through their tactile and kinesthetic senses. The next problem is to model the interface such that it can be returned to the user via force-feedback devices: the task is to define the fields of force corresponding to interface objects and events, and to design algorithms to synthesize these forces in such a way as to provide optimum real-time operation. The final problem concerns the hardware and software architecture to be used to facilitate the integration of this technology with contemporary graphic interfaces. An architecture model for a multimodal interface is presented: it is based on the notion of a multiagent model and breaks down inputs and outputs according to multiple modalities (visual, auditory and haptic). These modalities are represented by independent software components that communicate with one another via a higher-level control agent.

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 596-605.
summary	Our framework employs a convolutional autoencoder model to integrate urban morphology data and attribute vectors of screen-based buildings, generating final feature vectors that are subsequently used for clustering and comparative analysis. We carried out empirical testing of our methods using data from the cities of Chongqing and Shanghai in China. This comparative study identifies various categories of screen clusters, and demonstrates the framework’s effectiveness. The primary objective of this research is to elucidate the similarities and differences among screen-based building clusters, aiming to provide architects and urban designers with a more comprehensive understanding of the typological and topological characteristics of augmented space syntax. Through this approach, we hope to contribute to the development of more effective design strategies and policies for the implementation and integration of screen-based building clusters in urban environments.

source	International Journal of Architectural Computing vol. 2 - no. 1
summary	This paper proposes the application of some well known two-dimensional geometrical shape descriptors for the visualisation of the structure of architectural open spaces. The paper demonstrates the use of visibility measures such as distance to obstacles and amount of visible space to calculate shape descriptors such as convexity and skeleton of the open space. The aim of the paper is to indicate a simple, objective and quantifiable approach to understand the structure of open spaces otherwise impossible due to the complex construction of built structures.
