summary	Two different surveys were conducted for visual impact assessment (VIA) on urban streetscape namely – the visual perception and visualization tools. The first was focused on the visual perception between designers and nondesigners of the undergraduate students from four different public universities in Malaysia representing landscape architecture and business administration courses whereas the latter concentrated on students with a background of landscape architecture and quantity surveyor to evaluate static and dynamic visualization tools. The paper discussed the findings of the visual perception and visualization tools surveys, and its impact towards improving VIA on urban streetscape.

title	Enabling Component Reuse from Existing Buildings through Machine Learning, Using Google Street View to Enhance Building Databases
doi	https://doi.org/10.52842/conf.caadria.2022.2.577
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 577-586
summary	Intense urbanization has led us to rethink construction and demolition practices on a global scale. There is an opportunity to respond to the climate crisis by moving towards a circular built environment. Such a paradigm shift can be achieved by critically examining the possibility of reusing components from existing buildings. This study investigates approaches and tools needed to analyze the existing building stock and methods to enable component reuse. Ocular observations were conducted in Google Street View to analyze two building-specific characteristics: (1) facade material and (2) reusable components (window, doors, and shutters) found on building facades in two cities: Barcelona and Zurich. Not all products are equally suitable for reuse and require an evaluation metric to understand which components can be reused effectively. Consequently, tailored reuse strategies that are defined by a priority order of waste prevention are put forth. Machine learning shows promising potential to visually collect building-specific characteristics that are relevant for component reuse. The data collected is used to create classification maps that can help define protocols and for urban planning. This research can upscale limited information in countries where available data about the existing building stock is insufficient.

title	Computational simulation based daylight design for urban sites – validation, methodology and legality

summary	The creditability of using CAAD depends on the rigour of its methodology, the logic of its deduction and most importantly the feasibility of its results for practical use. This paper examines two lighting simulation software as the basis for providing a wider critic on the research of CAAD in the practice of architecture. The paper argues that the ‘contextual’ and appropriate use of a simple tool or method should be the thesis of CAAD research. Using an example, the paper then logically work out an example of how that could be done, and the basis of its contextual logic. The example illustrated here concludes the validity of the software and its implication for legal use. Furthermore, the paper provides a critic of CAAD for regulatory and legal acceptance. The experience in Hong Kong is illustrated.

summary	To validate the hypothesis that virtual heritage papers are reliant on providing scholarly argumentation based on 3D models, and convenient access is provided to these models where relevant, this study reviewed 264 articles from the last three available proceedings of major digital heritage events and conferences (14 in total). The findings revealed this was not the case, few contain references to accessible 3D models. We discuss why this may be so, and we outline recommendations for ensuring that virtual heritage 3D models can be preserved and accessed.

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	From Ramon Llull to Image Idea Generation
source	International Conference on Generative Art
summary	Our minds follow familiar well trodden paths, and we sometimes need mechanical help to find new, undiscovered thoughts and ideas. Ramon Llull was a Christian philosopher who used a mechanical way of investigating truth, a set of concentric wheels on which words were written. By rotating the wheels, the words were combined in unexpected ways. A similar technique has been (re-)invented, randomised and changed by Edward de Bono and is called Lateral Thinking. Can we apply this technique to image idea generation? This paper describes a first attempt at building an image idea generator for use by artists and non-artists alike, and sets out plans for a new a more powerful version. An image idea generator takes no (or very few) instructions from the user and creates a set of images from which the user chooses those he likes best. The purpose of an image idea generator is to easily create previously un-thought of images, to easily explore the 2D world of color and form.

title	Predication, Fiction, and Artificial Intelligence
source	27 (21) p. : ill. May, 1990. 90-11. includes bibliography
summary	This paper describes the SNePS knowledge-representation and reasoning system. SNePS is an intentional, propositional, semantic-network processing system used for research in AI. The author looks at how predication is represented in such a system when it is used for cognitive modeling and natural- language understanding and generation. In particular, the author discusses issues in the representation of fictional entities and the representation of propositions from fiction, using SNePS. A brief survey is given of four philosophical ontological theories of fiction and sketch an epistemological theory of fiction (implemented in SNePS) using a story operator and rules allowing propositions to 'migrate' into and out of story 'spaces.'

title	Shape-Sensitive Configurational Descriptions of Building Plans
source	International Journal of Architectural Computing vol. 10 - no. 1, 33-52
summary	While the traditional graph-theoretic techniques of space syntax are able to provide a rich description of the spatial configuration of buildings, they are not sufficiently shape sensitive. Therefore, techniques are proposed to describe building plans as configurations of spaces taking into consideration the elements of shape explicitly. First, the traditional space syntax techniques are applied to a more shape-sensitive partition of a plan in order to find out if these techniques would reveal any interesting shape property of the plan. Following this, a technique to characterize the spatial units of a plan is suggested taking into consideration how surfaces become visible from these units. Finally, a plan is described as the configuration of triangles defined by the vertices of the shape of the plan, and triangulation is used as a technique for a shape-sensitive description of spatial configuration.

title	After Imagery - Evaluating the use of mixed reality (MR) in urban planning
doi	https://doi.org/10.52842/conf.ecaade.2020.1.187
source	Werner, L and Koering, D (eds.), Anthropologic: Architecture and Fabrication in the cognitive age - Proceedings of the 38th eCAADe Conference - Volume 1, TU Berlin, Berlin, Germany, 16-18 September 2020, pp. 187-196
summary	While many researchers have developed interesting use cases for Mixed Reality (MR) in urban environments, the paper argues that determining the long-term viability of such applications as planning tools will likely require evaluating whether such applications are compatible with the democratically mandated procedures in Urban Planning. The paper compares this claim to current debates regarding the legality of the use of digital imagery in Urban Planning today. The paper elaborates these arguments through case studies done in Oslo, Norway in the context of developing the "Nordic Digital City". The case studies involve the use of MR in 1) a public competition, 2) a regulation plan, and 3) a building permit. The study thus presents some of the benefits and challenges of using these technologies in such a manner, particularly regarding accuracy, user feedback, and robustness as a common interface. The paper concludes that MR offers several benefits to Urban Planning, but will likely require a highly digitized competent public sector in order to function, in addition to requiring negotiation between the required user data and user privacy rights, suggesting that MR development may migrate from a primarily technical domain to a matter of public policy.

title	Implicit Learning and Tacit Knowledge: An Essay on the Cognitive Unconscious
source	New York: Oxford University Press
summary	In this new volume in the Oxford Psychology Series, the author presents a highly readable account of the cognitive unconscious, focusing in particular on the problem of implicit learning. Implicit learning is defined as the acquisition of knowledge that takes place independently of the conscious attempts to learn and largely in the absence of explicit knowledge about what was acquired. One of the core assumptions of this argument is that implicit learning is a fundamental, "root" process, one that lies at the very heart of the adaptive behavioral repertoire of every complex organism. The author's goals are to outline the essential features of implicit learning that have emerged from the many studies that have been carried out in a variety of experimental laboratories over the past several decades; to present the various alternative perspectives on this issue that have been proposed by other researchers and to try to accommodate these views with his own; to structure the literature so that it can be seen in the context of standard heuristics of evolutionary biology; to present the material within a functionalist approach and to try to show why the experimental data should be seen as entailing particular epistemological perspectives; and to present implicit processing as encompassing a general and ubiquitous set of operations that have wide currency and several possible applications. Chapter 1 begins with the core problem under consideration in this book, a characterization of "implicit learning" as it has come to be used in the literature. Reber puts this seemingly specialized topic into a general framework and suggests a theoretical model based on standard heuristics of evolutionary biology. In his account, Reber weaves a capsule history of interest in and work on the cognitive unconscious. Chapter 2 turns to a detailed overview of the experimental work on the acquisition of implicit knowledge, which currently is of great interest. Chapter 3 develops the evolutionary model within which one can see learning and cognition as richly intertwining issues and not as two distinct fields with one dominating the other. Finally, Chapter 4 explores a variety of entailments and speculations concerning implicit cognitive processes and their general role in the larger scope of human performance

source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 763-769
summary	This paper presents an innovative approach towards parametric design. The use of histograms is suggested as a design interface representing the spatial parametric relationships in an unfolded tabular form. The unfolded tabular and bar histogram provides a schematic representation of the design model and allows creating parametric relationships between the design components.

title	Modeling the Digital Earth in VRML
source	Technical Note no. 559, SRI International, Menlo Park
summary	This paper describes the representation and navigation of large, multi-resolution, georeferenced datasets in VRML97. This requires resolving nontrivial issues such as how to represent deep level of detail hierarchies efficiently in VRML; how to model terrain using geographic coordinate systems instead of only VRML's Cartesian representation; how to model georeferenced coordinates to sub-meter accuracy with only single-precision floating point support; how to enable the integration of multiple terrain datasets for a region, as well as cultural features such as buildings and roads; how to navigate efficiently around a large, global terrain dataset; and finally, how to encode metadata describing the terrain. We present solutions to all of these problems. Consequently, we are able to visualize geographic data in the order of terabytes or more, from the globe down to millimeter resolution, and in real-time, using standard VRML97.

source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary	The graphic intention is a peculiarity of the architectural drawing. It is enough to compare the ground plan of an unifamiliar housing insulated of Le Corbusier with another of Mies van der Rohe to realise the diversity of graphic styles, but is important to take conscience of the complexity that carries to interpret the symbols that appear in those documents, because as architects we either realize plans that the instructions are described or measures to be able to execute the work and in other occations representations for his edition aimed to a especialized public. For this reason, and because not always is arranged the best possible documentation, we consider that the majority of vectorisations they exist in the market don’t plenty satisfied our needs as teaching staff of graphic expression and CAD, althoug we can always be using the same systems of projection or codified representations, it is imposed a lot of times to interpret acording the context the different signs and graphic registers used. We know experimental applications that go beyond, they even arrive to generate a 3D model from a lifted hand draw that represents three orthogonal projections of it, but it isn’t less certain that its utility is restricted to fields very specialised and the option that we propose, there is not knowledge at least to us that it exist; commercially speaking. Our porpose has been to develope a symple metedology of vectorisation but adapted to the special idiosyncrasy of the needs of an architecture student that with frequency for his formation requires to generate with CAD models 2D and 3D of architectural projects from the information contented in magazines, and with them create several formas analysis. The most important difference in the matter to other systems is the interactivity of the procedure that let personify the exit file, even the wide diversity of graphic registers that it exist in the entrance, being the user only once has to identify and interpret the signs to detect, and then the process is realized automatically to any plant of the building or equivalent projection.

title	Formal grammar methodology for digital visualization of Islamic geometric patterns
source	International Journal of Architectural Computing 2022, Vol. 20 - no. 2, pp. 297–315
summary	In the oriental practice of art and architecture, and among the regions under their influence, Islamic geometricpatterns (IGPs) have been widely used, not only due to aesthetics and decoration but also to make it possibleto cover wide flat surfaces, curved surface of domes, and perforated surfaces of window and partitions, withperfectly tessellated shapes. However, with advances in time and technology, these techniques could notconnect to the new technologies and benefit from the capacities of digitalization. Recent progress in scienceand technology tends to open new doors to study geometrical patterns by digitalizing the old ones anddeveloping new variations. This study looks at formal grammar and computer science to introduce a newapproach to digital visualization of available IGPs, particularly, star patterns.We investigate the potentials of developing a re-writing system for simulation of IGPs to provide a flexibleplatform, which allows introducing IGP to CAD/CAM software without previous knowledge on their designor drawing techniques. This methodology allows designers to directly develop various scenarios of IGPapplications and implement them on related CAD/CAM tools.Formal language and grammar theories, based on applied mathematics are contributing to the advancementsof computer science and digital modeling. They can provide an opportunity to express relational definitionand written equivalents of the geometries by using strings and symbols. It is supposed that by using the formalgrammar frameworks, certain languages could be developed to visualize IGPs in a machine-friendly way, andconsequently, this computational interpretation of IGPs facilitates their application and further developments,for example, regards to digital fabrication.The presented method of IGP visualization is developed as a C#-based add-on for Grasshopper in Rhino3D,one of the main modeling tools used by architects and product designers

source	PDC 02 - Proceedings of Participatory Design conference, T. Binder, J. Gregory, I. Wagner (eds.), Malmö. Sweden, 23-25 June 2002 [ISBN 0-9667818-2-1]
summary	This paper outlines the interdisciplinary nature, collaborative work patterns and role of aesthetics in the Cuthbert Hall Virtual College research project at the Cambridge University Moving Image Studio (CUMIS) and the Centre for Applied Research in Education Technology (CARET). The project identifies key properties of dramatically engaging real-time three-dimensional virtual environments (RT 3D VE) and how the holistic experiential phenomenon of place is organised and mediated through spatial narrative patterns. Interdisciplinary by nature, the project requires a collaborative approach between science, engineering, media and architecture, and the results are revealing for all these areas. The Cuthbert Hall project invites discussion of the importance in the creation and use of RT 3D VE's - under single and multi-user conditions - of articulate aesthetics (the quality of architectural, visual and audio design; the production and incorporation of dramatic properties) and of the conditions required for collaborative, communicative use of the environment. The full theoretical and technical discussions as well as the evaluation results are outside the scope of this submission.
