title	A Case for Computer-Assisted Creativity through Clarity, Project 12 CAD and Beyond
source	CAD Creativeness [Conference Proceedings / ISBN 83-905377-0-2] Bialystock (Poland), 25-27 April 1996 pp. 31-35
summary	A paper exploring the opportunities of different Design Media for the benefit of Architectural and Urban Composition. It is argued that during the design process, the designer develops Models for a projected end result, which are visualised in the form of Images using traditional media. The Computer affords the possibility of creating (virtual) Models from which Images can be taken. Current types of Computer Interfaces still form an obstacle for creative computer assisted design, comparable to Sketching. It is argued that the Clarity of the medium will need to be enhanced, if it is to become an Instrument for truly creative design. Using the example of an educational, practical CAD exercise, the case for' Clarity for the benefit of creative Computing is put forward.

title	Spatial reasoning: improving computational efficiency
source	Automation in Construction 9 (4) (2000) pp. 361-367
summary	When spatial data is analysed the result is often very computer intensive: even by the standards of contemporary technologies, the machine power needed is great and the processing times significant. This is particularly so in 3-D and 4-D scenarios. What we describe here is a technique, which tackles this and associated problems. The technique is founded in the idea of quad-tesseral addressing; a technique, which was originally applied to the analysis of atomic structures. It is based on ideas concerning Hierarchical clustering developed in the 1960s and 1970s to improve data access time [G.M. Morton, A computer oriented geodetic database and a new technique on file sequencing, IBM Canada, 1996.], and on atomic isohedral (same shape) tiling strategies developed in the 1970s and 1980s concerned with group theory [B. Grunbaum, G.C. Shephard, Tilings and Patterns, Freeman, New York, 1987.]. The technique was first suggested as a suitable representation for GIS in the early 1980s when the two strands were brought together and a tesseral arithmetic applied [F.C. Holdroyd, The Geometry of Tiling Hierarchies, Ars Combanitoria 16B (1983) 211–244.; S.B.M. Bell, B.M. Diaz, F.C. Holroyd, M.J.J. Jackson, Spatially referenced methods of processing raster and vector data, Image and Vision Computing 1 (4) (1983) 211–220.; Diaz, S.B.M. Bell, Spatial Data Processing Using Tesseral Methods, Natural Environment Research Council, Swindon, 1986.]. Here, we describe how that technique can equally be applied to the analysis of environmental interaction with built forms. The way in which the technique deals with the problems described is first to linearise the three-dimensional (3-D) space being investigated. Then, the reasoning applied to that space is applied within the same environment as the definition of the problem data. We show, with an illustrative example, how the technique can be applied. The problem then remains of how to visualise the results of the analysis so undertaken. We show how this has been accomplished so that the 3-D space and the results are represented in a way which facilitates rapid interpretation of the analysis, which has been carried out.

title	EL COLOR DIGITAL EN EL DISEÑO DE TESELACIONES PERIODICAS (The Digital Color in the Design of Periodical Teselations)
source	SIGraDi biobio2001 - [Proceedings of the 5th Iberoamerican Congress of Digital Graphics / ISBN 956-7813-12-4] Concepcion (Chile) 21-23 november 2001, pp. 64-66
summary	The present study of fundamentally exploratory type tries to examine the distribution of the color in the structures of repetition designed according to the Mathematical Theory of the Tessellations and inspired in the grafphic work of the artist holandes M.C.Escher. The results reached are product of the exercises pedagogicos carried out in the catedra of design of the color of the Design Workshop I, Universidad del Bío-Bío, among the years 1996 and 2000 to pursue a design graphic degree.

title	Managing Integrity in Design Information Flows
source	Computer Aided Design (May, 1996). 28:6n, pp. 551-565
summary	The purpose of this work is to develop automatic methods of semantic integrity maintenance, in support of concurrent engineering. Semantic integrity relations in any final engineering design are built up incrementally, through the use of different computer applications. Here, the structure of these integrity relations are formalized for representation within a database. When changes to a design have to be made, they can invalidate integrity relations in other parts of the design. Formal methods are defined for identifying what data and integrity relations are invalidated by any change. Methods for making changes that minimize re-design are described and formalized. Opportunities for using semantic integrity to assess progress on a design are reviewed.

title	GIS and Environmental Modeling: Progress and Research Issues
source	Fort Collins, CO: GIS World Books, pp.451-454
summary	GIS and Environmental Modeling: Progress and Research Issues Michael F. Goodchild, Louis T. Steyaert, Bradley O. Parks, Carol Johnston, David Maidment, Michael Crane, and Sandi Glendinning, Editors With growing pressure on natural resources and landscapes there is an increasing need to predict the consequences of any changes to the environment. Modelling plays an important role in this by helping our understanding of the environment and by forecasting likely impacts. In recent years moves have been made to link models to Geographical Information Systems to provide a means of analysing changes over an area as well as over time. GIS and Environmental Modeling explores the progress made to date in integrating these two software systems. Approaches to the subject are made from theoretical, technical as well as data stand points. The existing capabilities of current systems are described along with important issues of data availability, accuracy and error. Various case studies illustrate this and highlight the common concepts and issues that exist between researchers in different environmental fields. The future needs and prospects for integrating GIS and environmental models are also explored with developments in both data handling and modelling discussed. The book brings together the knowledge and experience of over 100 researchers from academic, commercial and government backgrounds who work in a wide range of disciplines. The themes followed in the text provide a fund of knowledge and guidance for those involved in environmental modelling and GIS. The book is easily accessible for readers with a basic GIS knowledge and the ideas and results of the research are clearly illustrated with both colour and black and white graphics.

title	Artificial Life
source	Boden, M. A. (1996). The Philosophy of Artificial Life, 39-94.New York and Oxford: Oxford University Press
summary	Artificial Life contains a selection of articles from the first three issues of the journal of the same name, chosen so as to give an overview of the field, its connections with other disciplines, and its philosophical foundations. It is aimed at those with a general background in the sciences: some of the articles assume a mathematical background, or basic biology and computer science. I found it an informative and thought-provoking survey of a field around whose edges I have skirted for years. Many of the articles take biology as their starting point. Charles Taylor and David Jefferson provide a brief overview of the uses of artificial life as a tool in biology. Others look at more specific topics: Kristian Lindgren and Mats G. Nordahl use the iterated Prisoner's Dilemma to model cooperation and community structure in artificial ecosystems; Peter Schuster writes about molecular evolution in simplified test tube systems and its spin-off, evolutionary biotechnology; Przemyslaw Prusinkiewicz presents some examples of visual modelling of morphogenesis, illustrated with colour photographs; and Michael G. Dyer surveys different kinds of cooperative animal behaviour and some of the problems synthesising neural networks which exhibit similar behaviours. Other articles highlight the connections of artificial life with artificial intelligence. A review article by Luc Steels covers the relationship between the two fields, while another by Pattie Maes covers work on adaptive autonomous agents. Thomas S. Ray takes a synthetic approach to artificial life, with the goal of instantiating life rather than simulating it; he manages an awkward compromise between respecting the "physics and chemistry" of the digital medium and transplanting features of biological life. Kunihiko Kaneko looks to the mathematics of chaos theory to help understand the origins of complexity in evolution. In "Beyond Digital Naturalism", Walter Fontana, Guenter Wagner and Leo Buss argue that the test of artificial life is to solve conceptual problems of biology and that "there exists a logical deep structure of which carbon chemistry-based life is a manifestation"; they use lambda calculus to try and build a theory of organisation.

title	A Formal Structure for Nonequivalent Solid Representations
source	Proceedings of IFIP WG 5.2: Workshop on Knowledge Intensive CAD II, (eds.) S. Finger, M. M‰ntyl‰, and T. Tomiyama. International Federation for Information Processing
summary	This work is based on the recognition that there will always be a need for different representations of the same entity, albeit a building or building part, a shape or other complex attribute. Different representations support different sets of operations with varying efficiencies. Given our expectation that such multiple representations will always exist, there is a need, formally, to define the relations between alternative representations, in order to support translation and identify where exact translation is or is not possible, and to define the coverage of different representations. A method for the analysis of representations is developed, which is applied to four different solid modeling representations.
