title	Computer Implementation of Shape Grammars
source	Department of Architectural Science, University of Sydney
summary	An approach is taken that shape grammars can be used as a possible vehicle for automated design generation. Historical background of shape grammars is discussed with emphasis on vocabulary/syntax aspect of the design process and significance of class solutions to problems. Similarities with expert system mechanics and structure is highlighted and advantages and disadvantages of rule-based and frame-based systems are considered. These concepts are implemented in a computer program written in LISP employing icon driven graphic interface with tools for creating shapes and rules. Finally, problems associated with adopted reasoning strategies are reported and areas of further development and improvement suggested. [UNPUBLISHED. CADLINE has abstract only]

title	Level-of-Detail Visualization of Architectural Models
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 831-836
summary	The work presented in this paper aims to use level-of-detail representation in realizing interactive walkthroughs or ignoring useless details in large architectural models. In order to choose the right representation of a model, we have to evaluate the error committed when using a simplified version instead of the full description of an object. This error depends on the object deformation during the simplification process but also on the importance of this object in the current viewing conditions. This "visible" error is used with different visualization strategies to find the model representation which satisfies either a quality criterion or a cost condition.

source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 231-239
summary	This paper presents a method for representing complex models with various levels of detail. It is based on a geometric simplification algorithm and is applied to a scene described by a rooted-tree structure. In order to control the restuting image quality and the computation time, we propose two algorithms which allow to choose one representation of the scene.

summary	Architects are often obliged to use CAD and even to show a 3D CAD model of their design (that most CAD programs are capable of doing now) and most people are mislead by such slogans as the 3D is the most important part of a design although its just like drafting from other tricky viewpoints. We all know that a building is far more complex than the a bundle of sections, elevations and perspective views. It's a model of space where all building construction parts and other effects (even time, sunshine), that create and help to communicate this space have very complex cross references with each other. If we want to describe it with a program we have to create a digital building, and architects have to communicate this digital building towards each other in the design phase, if more than one architect or engineer is working on the building simultaneously.

title	Autonomous vehicle navigation with real-time 3D laser based positioning for construction
source	Automation in Construction 5 (4) (1996) pp. 261-272
summary	Autonomous Guided Vehicles (AGVs) are a way of life in manufacturing where navigation can be done in a structured environment. Construction is an unstructured environment and requires a different type of navigation system to deal with three dimensional control and rough terrain. This paper provides a review of navigation systems that utilize dead-reckoning in conjunction with absolute referencing systems such as beacon-based systems, and vision and mapping based system. The use of a real-time laser based technology is demonstrated as a new form of navigation. This, technology does not rely on dead reckoning. The paper outlines the issues and strategies in guiding an autonomous vehicle utilizing only the laser-based positioning system. Algorithms were developed to provide real-time control of the AGV. The laser based positioning system is unique in that it provides three dimensional position data with five updates per second. No other system can provide this level of performance. This allows for control of end effectors and autonomous vehicles in complex and unstructured three dimensional environments. The use of this new type of navigation makes possible the automation of large complex assemblies in rough terrain such as construction.

title	Reconfiguring Collaboration by Computational Means Tex-Fab: A new model for collaborative engagement
doi	https://doi.org/10.52842/conf.acadia.2011.x.f7u
source	Parametricism (SPC) ACADIA Regional 2011 Conference Proceedings
summary	TEX-FAB is a non-profit organization founded between three universities in Texas with the primary function of connecting design professionals, academics, and manufactures interested in digital fabrication. The three co-directors established TEX-FAB as a collective action, one that attempts to combine divergent interests and capabilities, for the purpose of strengthening the regional discourse around digital fabrication and parametric design. The three primary avenues for accomplishing this goal are set out as Theoria (Lectures / Exhibitions), Poiesis (Workshops) and Praxis (Competition). We see this type of effort as a new paradigm focused on providing a network of affiliated digital fabrication resources, and a platform for education/ exchange on issues of parametric modeling. It is our position that TEX-FAB engages the new and growing awareness of a regional and global hybridization. We seek to leverage the burgeoning global knowledge base to produce a more specific and contextual dialogue within the region we operate, teach, and practice.

title	Handling of Dynamic 2D/3-D Graphics in Narrow-Band Mobile Services
source	Virtual Worlds on the Internet, IEEE Computer Society, pp. 147-156
summary	The factors limiting the efficient delivery and presentation of multimedia material in the cellular environment are, among others, the low bandwidth of the transmission channel(s) and the modest capabilities of truly mobile terminals. The ACTS 1 project MObile Media and ENTertainment Services (MOMENTS) is leveraging the usage of state-of-the-art technique for the handling of vector graphics and animation contents, obtained through very low data transmission channels, in order to provide veru attractive multimedia services in that environment. This paper focuses on the achievements obtained within MOMENTS in regard to the handling of dynamic 2D/3D graphics for the projected wireless multimedia services.

title	The Geographical Alpine Information System “Galpis” in the Raumalp Project. Outlay and Output
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	RAUMALP, an interdisciplinary research project of the Austrian Academy of Sciences, shall examine problem areas of spatial development on community level in the Austrian alpine region. The aim is the investigation of scientific basics for political decision finding, especially for the regional-specific realisation of the Alpine Convention. All ascertained information shall be included in “GALPIS”, a comprehensive Alpine Space Information System. GALPIS based on ESRI ArcGIS and MS Access software works with data from different sources, like ISIS, the electronic data base of Statistic Austria, and original data and maps gathered and elaborated by the working groups of RAUMALP. This also includes ecological raster data. Dealing with administrative units, „real“ space and raster space, RAUMALP will integrate the different space levels mostly to administrative spatial units representing the existing 1145 communities of the RAUMALP study area. This will be realised by overlay of grids, types of land use and communitypolygons. Major task of GALPIS is a conversion of former communal data (p. e. 1451 communities in 1951) that should represent the recent administrative boundaries. By this way it is possible to make thematic and time-integrative analyses of community data. GIS modelling of the six case studies is more complex. The conceptual model has to integrate several vector and raster layers such as land plots (“Digitale Katastralmappe”), types of land use (“Land Use and Land Cover Austria” by M. Seger) and biodiversity. P. e., the working group settlement is using a logical data model based on the entity “building” with the attributes “construction”,“function”, etc.

summary	The lack of urban planning has made the recreation areas increasingly smaller in the cities. Parks and squares gradually gave way to streets and avenues to try to accommodate the growing number of cars and motorcycles. An alternative that tries to balance recreation areas and urban roads was found in the city of San Francisco (USA). Parklets are temporary extensions of urban sidewalks that occupy a few parking spaces. This article aims to demonstrate the potential of parametric modeling in the development of parklets. Thus, anthropometric studies, amount of parking spaces and types of benches were used as input parameters. Rhinoceros and grasshopper programs were used for modeling, while 3D Studio Max was used for rendering. With this study it was possible to verify that when the project is parameterized the processes of creation and modification became faster, reducing design and implementation time.

title	Cityspace, Cyberspace, and The Spatiology of Information
source	Boyer,C. & Gandelsonas.,M. The New Urbanism Princeton University Press
summary	The concept of space has been critical to architectural theory for over seventy years now. It remains however, an elusive idea, on the one hand meaning and referring to everything, on the other hand meaning and referring to nothing. Why? Is it because "space," like "time," is a category outside of which thinking itself seems to be impossible, just as Kant asserted? Is it simply one of those irreducible, universal without which the world as such would cease to in any sense, let alone be of, or perceived by, sentient beings givens be thought Certainly to suggest that space itself is an active, causative agent of some sort risks opening that discussion up to universalizing of the most extreme and vacuous kind. For if I am not to be a dualist, positing a separate, a-spatial and a-temporal realm for thought and feeling, then what in the real world, I can easily ask, occupies neither space nor time? What is it that cannot be reduced, be analyzed, or be spoken of finally in the language of position, duration, connection, inclusion, transformation, and so forth? Nothing. If we wish to reach deeply into the "nature" of "space itself" then, I believe we must allow into it, as it were, of some sort: not the aether of Nineteenth century science perhaps, but a registering, tracing, questioning, remembering substance, spread as thinly as we can imagine but present nonetheless, and definitive of versus because of how it pools, how it vibrates, how it scatters difference, a substance here there difference.

summary	New technologies and uncontrolled open-data policies lead public to a new way of approaching the built environment. To enlarge the competences of the professionals that work within the cities, we believe that providing a deep and dynamic knowledge on the heritage and urban built environment is the more effective solution to offer a unique support to the needs. By providing a boosted geographical database with detailed information about the status of each building, we aim to support the professional by providing a neat vision about vacant buildings available citywide. We think this knowledge is an important asset in covering every kind of public requests: from flat to rent to an abandoned building to restore or to drive better investors. The city of Trento will be the pilot project to test these statements.We studied the phenomenon of pushing new constructions rather investing on the reuse of abandoned buildings with the consequences of unsustainable land use. To address the work we adopted a comprehensive approach across the fields of urbanism, ICT engineering and social sciences. We believe that sharing knowledge and know-hows with municipalities, agencies, and citizens is the way to support better market strategies as well as urban transformation policies.

summary	The objective of this paper is to evaluate the use of virtual reality as a potential decision-making tool to cognitively evaluate urban daylighting ambiences. This paper evaluates the solar effects visual perception in a real urban path in comparison to a virtual urban path in order to extract the characteristics of these effects and use them to figure out the necessary conditions for generating a physical and sensitive phenomena simulation. The comparison is based on questionnaires and interviews with participants on their judgements on sunlight during their walk through the chosen path. Our results highlight the relation between perception and the context of the urban environment, and prove that -in spite of its limits- virtual reality is able to simulate a large part of real solar effects.

summary	Urban environment is a “sensible” space; it can manifest itself to our senses through the process of perception. The comprehension of the relation between man and his environment requires a study of spatial perception and its modes of interpretation. This paper proposes to study the perception by using the Virtual Reality (VR) technologies as a tool of qualitative analysis. The study presents an exploratory analysis of visual perception in a real urban path and its virtual modeling. It shows the potentials of virtual environments in the qualitative assessment of urban spaces.

title	An alternative Palladian shape grammar: A subdivision grammar for Palladian villas
doi	https://doi.org/10.52842/conf.caadria.2012.415
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 415–424
summary	This paper describes a shape grammar that recreates Palladio’s villas. A Palladian grammar was previously proposed by Stiny and Mitchell. However, this alternative grammar uses different parametric shape rules and methodology to test the hypothesis that different grammars can generate the same corpus of designs. The formalism is then implemented using a computerised design tool. The grammar includes subdivision rules that allow for a more economical formulation. The project is part of wider research aimed at formulating a generic housing grammar.

summary	This paper describes a system for generating customized mass housing. The aim is to provide dwellings at an affordable cost with recourse to mass production and yet guarantee that they are tailored to their users. It combines two systems, a rule-based design system and a prefabricated building system. The integration of both systems is achieved through the development of a computer tool to assist designers in the various stages of the housing design process. This tool produces three kinds of outputs: three dimensional models, construction drawings, and a list of construction elements, including their cost and information for manufacturing.

summary	Determining whether a given point lies inside or outside a simple polygon is an important problem in many applications, including computer vision systems and computer-assisted political redistricting systems. In this paper the authors give algorithms for inclusion problems that are efficient for polygons that are 'close to convex' in a certain precise sense. An empirical study of polygons that arise in several applications shows that typical polygons are indeed 'close to convex,' and a program implementing the algorithm shows that is extremely efficient on point sets of practical sizes
