title	The Generation of Color Sequences for Univariate and Bivariate Mapping
source	IEEE Computer Graphics and Applications. February, 1986. vol. 6: pp. 24-32 : ill. some col. includes bibliography
summary	Recent technological advances have made it feasible to produce full color statistical maps on computer-controlled display systems. This has caused an appraisal of the use of color to represent statistical variables, and the development of a theoretical structure for the choice of suitable univariate and bivariate map coloring schemes. Realization of such schemes in an intuitive and controlled way is important to the comprehension of statistical variables from maps. Therefore, a method of generating specific color sequences within the framework of a uniform color space, allowing for the intuitive specification of color sequences and for their realization on various display systems, is presented

title	Planar Point Location Using Persistent Search Trees
source	Communications of the ACM July, 1986. vol. 29: pp. 669-679 : ill. includes bibliography.
summary	A classical problem in computational geometry is the planar point location problem. This problem calls for preprocessing a polygonal subdivision of the plane defined by n line segments so that, given a sequence of points, the polygon containing each point can be determined quickly on-line. Several ways of solving this problem in O(log n) query time and O(n) space are known, but they are all rather complicated. The authors propose a simple O(log n) query-time, O(n) space solution, using persistent search trees. A persistent search tree differs from an ordinary search tree in that after an insertion or deletion, the old version of the tree can stillÔ h)000*°° ÔŒ be accessed. A persistent form of binary search tree that supports insertions and deletions in the present and queries in the past is developed. The time per query or update is O(log m), where m is the total number of updates, and the space needed is O(1) per update. The planar point location algorithm is an immediate application of this data structure. The structure also provides an alternative to Chazelle's 'hive graph' structure, which has a variety of applications in geometric retrieval

title	On the process of creativity in puzzles, inventions, and designs
source	Automation in Construction 7 (2-3) (1998) pp. 123-138
summary	The most common means of identifying creativity has been through its products. In architecture, music, writing, art, even puzzle solving and scientific discovery, the prerequisite for considering creativity has been the presence of a creative product. Alternatively, anecdotal descriptions have been used to identify processes that are considered creative. Many scientific discoveries have been linked to a sudden realization or unexplainable revelation punctuated with the AHA! response. Outside of the creative product itself and the AHA! response, the kinds of concrete evidence that point to the process of creativity are precious few. Our purpose here is to further examine these phenomena and develop hypotheses about the nature of the creative process. Our ultimate aim is to develop a general theory of creativity. We intend to base this theory on a set of conditions that are necessary for the creative process to take place in a number of domains: puzzles, scientific discoveries, and design, with special emphasis on architectural design.

title	Design Protocol data and novel design decisions
source	Design Studies, 16 (#2, April), 211-236
summary	This work is a part of The Delft Protocols Workshop which is an international gathering of experts on design research. The objective is to study the behaviours of designers using techniques of cognitive psychology in general and protocol analysis in particular. The purpose of this paper is to explore the relationship between visual-graphic data processing and novel design ideas. Several analyses dealing with verbal-conceptual and visual-graphic data have been conducted; and the relationships between design activities and design decisions have been explored. The findings indicate that phases of the design process and the activities correlate with key design decisions.

title	Computational Specification of Building Requirements in theEarly Stages of Design
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	We have been exploring computational techniques to help building designers to specify design requirements during the early stages of design. In the past, little has been accomplished in this area either in terms of innovative computational technologies or the improvement of design performance.The prospect of improving design productivity and creating a seamless process between requirements specification and formal design are our primary motivations. This research has been conducted as partof a larger project entitled SEED (Software Environment to Support Early Phases in Building Design). SEED features an open-ended modular architecture, where each module provides support for a design activity that takes place in early design stages. Each module is supported by a database to store and retrieve information, as well as a user interface to support the interaction with designers. The module described in this paper, SEED-Pro (the architectural programming module of SEED), is a workingprototype for building design requirements specification. It can be used by other modules in SEED or by design systems in other domains, such as mechanical engineering, civil engineering, industrial designand electrical engineering. Our approach to SEED-Pro is divided into two phases: core, and support functionalities. The core functionalities operate in an interactive mode relying on a case-based approach to retrieve and adapt complex specification records to the problem at hand. The supportfunctionalities include the case-base, the data-base, and the standards processing environment for building specification tasks. Our findings indicate that SEED-Pro: (1) is a tool that structures the unstructured domain of design requirements; (2) enables the integration of design requirements with the rest of the design process, (3) leads to the creation of complex case-bases and (4) enables the observation of their performance in the context of real world design problems.

title	An electronic design assistance tool for case-based representation of designs
source	Automation in Construction 6 (4) (1997) pp. 265-274
summary	In precedent based design, solutions to problems are developed by drawing from an understanding of landmark designs. Many of the key design operations in this mode are similar to the functionalities present in case-based reasoning systems: case matching, case adapting, and case representation. It is clear that a rich case-base, encoding all major product types in a design domain would be the centerpiece of such an approach. EDAT (Electronic Design Assistance Tool) is intended to assist in precedent based design in the studio with the potential of expansion into the office setting. EDAT has been designed using object oriented system development methods. EDAT was used in a design studio at Carnegie Mellon University, during Spring 1996.

title	Problem Structuring in Architectural Design
source	February, 1987. [4], 15 p. : ill. includes bibliography
summary	The purpose of this research is to describe in operational terms the process of problem structuring while solving spatial problems in architectural design. The designer's behavior is described in terms of problem structuring, when problem parameters are established or transformed, and in terms of problem solving when these parameters are satisfied in a design solution. As opposed to problem solving, the structuring of problems is an under-studied but crucial aspect of complex tasks such as design. This work is based on observations derived from verbal protocol studies. To consider various levels of skill, the research subjects range from professional architects to novice designers. Subjects are given space planning problems which require them to develop solutions in accordance with individually established constraints and criteria, the majority of which are not explicit stated in the problem description. Based on the results of the protocol analysis, a framework is developed which explains how information processing characteristics, problem structure and different levels of expertise interact to influence the designer behavior

title	Determining the impact of cad drafting tools on the building delivery process
source	The Int. Journal of Construction IT 2(1), pp.1-8
summary	Computer aided design is intended to change the way design and construction are carried out. at a minimum, this implies savings realized in terms of time spent and improvement of the quality of designs produced. to test this idea, we hypothesized that computer aided drafting and design operations may be instrumental in reducing the number of change orders issued and help control cost overruns by improving the accuracy of construction documents. we compared change orders in projects designed in the conventional media against ones developed with computers. we found that there is evidence supporting our hypothesis. furthermore, in the process of investigating this question, we found that computer applications to improve the management of existing building information (as-built drawings, building system related information, and the like) represent even more critical needs than those that can reduce change orders through more accurate design drawings.

title	A collaborative project experience in an architectural framework, working with Open Source applications and physical computing [Diseño de Plataformas Digitales e Interactivas: una experiencia educativa trabajando colaborativamente con aplicaciones de Código Abierto y Computación Física]
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	Nowadays, thanks to the telecommunication revolution and therefore the massive spread of Internet, we have seen the come up of international architectural offices with branches located in different continent, working in a collaborative fashion, surpassing physical and time frontiers. At the same time, the multidisciplinary work between designers, architects, engineers, programmers and even biologist, between others, have been taking place in the new network society. All transformations also supported by the arising of FOSS (Free Open Source Software) and the virtual communities behind them, which allow the creation of non-traditional or specific software, the association between disciplines, and also, the formation of meeting scenarios for a mixture of individuals coming up with multiple motivation to coexist in collaborative environment. Furthermore, it is possible to argue that Open Source applications are also the reflection of a social movement, based on the open creation and exchange of information and knowledge. Do the appeared of FOSS compel us to re-think our working and teaching methods? Do they allow new modes of organizing and collaborating inside our architectural practices?. This paper would like to address these questions, by presenting the results of the “Experience Design” course, which by implementing teaching methods based on Open Source principles and cutting-edge tools, seeks to approach students to these new “way of do”, knowledge and methodologies, and overall, focus them on the science behind the computer. This paper describes the “Experience Design” course, in which architectural graduate students of Universidad Diego Portales (Chile), put for first time their hands on the creation of interactive interfaces. By acquiring basic knowledge of programming and physical computing, students built in a collaborative way a responsive physical installation. The course use as applications “Processing” and “Arduino”. The first one is an Open Source programming language and environment for users who want to program images, animation, and interactions. It has a visual context and serve as a software sketchbook and professional production tool. Processing is a project initiated by Ben Fry and Casey Reas, at the MIT Media Lab (www.processing.org). The second is an Open Source electronics prototyping platform based on flexible, easy-to-use hardware and software. Arduino has a microcontroller (programmed with Processing language) which can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators (www.arduino.cc). Both environments shared a growing community of people working in related projects and extending useful assistance for beginners. In this paper it is presented the current state of the pilot course and some of the initials results collected during the process. Students and teacher’s debates and evaluations of the experience have been exposed. Together with a critical evaluation in relation to the accomplishment of the effort of place together different disciplines in one collaborative project akin, architecture, design, programming and electronic. Finally, futures modifications of the course are discussed, together with consideration to take in account at the moment of bring Open Source and programming culture into the student curriculum.

title	Conceptualizing the evolution of Tmor-Da
source	SIGraDi 2018 [Proceedings of the 22nd Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Brazil, São Carlos 7 - 9 November 2018, pp. 531-537
summary	The urban dynamics observable in an informal settlement are akin to the characteristics of a complex adaptive system. In this paper, we describe an Agent-Based Model designed to simulate the urban dynamics of an informal settlement, Tmor-Da, in Phnom Penh, Cambodia. The overarching goal was to understand the possible rules that guided the development of built forms and the use of residue spaces in Tmor-Da. A series of simulation experiments were used to examine alternative hypotheses derived from field work and desktop analysis related to morphological changes associated with spatial units, including homes, shops, the orphanage, church and temple. The results suggest that the complex, emergent patterns encapsulated within the informal settlement could be reproduced in a simulation model. We conclude that our model can be used as an investigative tool to explore the most plausible factors contributing to the evolutionary trajectory of an informal settlement.

source	IEEE Computer Graphics and Applications vol. 6.no. 3 (March, 1986): pp. 52-62
summary	This article describes the requirements for a graphical format on which a graphical on-line communications protocol can be based. It is argued that on-line graphical communications is similar to graphical session capture, and thus the author proposes an interactive graphical communications format using the GKSM session metafile. The discussion includes items that complement the GKSM metafile such as a format for on-line interactive exchange. One key application area of such a format is multimedia on-line conferencing. Therefore, a conferencing software architecture for processing the proposed format is presented. This format specification is made available to those planning multimedia conferencing systems

title	Three-dimensional Input and Visualization
source	Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 68-84
summary	The aim of this chapter is to investigate techniques by which man-computer interaction could be improved, specifically in the context of architectural applications of CAD. In this application the object being designed is often an assembly of defined components. Even if the building is not actually fabricated from such components, it is usually conceptualized in these terms. In a conventional graphics- based CAD system these components are usually represented by graphical icons which are displayed on the graphics screen and arranged by the user. The system described here consists of three- dimensional modelling elements which the user physically assembles to form his design. Unlike conventional architectural models which are static (i.e. cannot be changed by the users) and passive (i.e. cannot be read by a CAD system), this model is both 'user generated' and 'machine readable'. The user can create, edit and view the model by simple, natural modelling activities and without the need to learn complex operating commands often associated with CAD systems. In particular, the user can view the model, altering his viewpoint and focus of attention in a completely natural way. Conventional computer graphics within an associated CAD system are used to represent the detailed geometry which the different three-dimensional icons may represent. In addition, computer graphics are also used to present the output of the performance attributes of the objects being modelled. In the architectural application described in this chapter an energy- balance evaluation is displayed for a building designed using the modelling device. While this system is not intended to offer a completely free-form input facility it can be considered to be a specialist man-machine interface of particular relevance to architects or engineers.

title	From 2D Base Map To 3D City Model
source	UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, I.17-I.28
summary	Since 1997 Helsinki City Survey Division has proceeded in experimenting and in developing the methods for converting and supplementing current digital 2D base maps in the scale 1:500 to a 3D city model. Actually since 1986 project areas have been produced in 3D for city planning and construction projects, but working with the whole map database started in 1997 because of customer demands and competitive 3D projects. 3D map database needs new data modelling and structures, map update processes need new working orders and the draftsmen need to learn a new profession; the 3D modeller. Laser-scanning and digital photogrammetry have been used in collecting 3D information on the map objects. During the years 1999-2000 laser-scanning experiments covering 45 km2 have been carried out utilizing the Swedish TopEye system. Simultaneous digital photography produces material for orto photo mosaics. These have been applied in mapping out dated map features and in vectorizing 3D buildings manually, semi automatically and automatically. In modelling we use TerraScan, TerraPhoto and TerraModeler sw, which are developed in Finland. The 3D city model project is at the same time partially a software development project. An accuracy and feasibility study was also completed and will be shortly presented. The three scales of 3D models are also presented in this paper. Some new 3D products and some usage of 3D city models in practice will be demonstrated in the actual presentation.

title	CAD and Management of Construction Projects
source	Journal of Construction Engineering and Management, Vol. 112, December, pp. 557-565
summary	The increasing interest in computer-aided design (CAD) has prompted research that is aimed at identifying the opportunities for construction managers and building contractors. It has been found that the use of CAD systems in the U.K. is mainly confined to the production of detailed drawings. Indeed, most of the systems used are 2-D drafting tools and incapable of supporting the integration of even modest amounts of nongraphical (construction) data. On the other hand, many 3-D modeling systems have the potential to integrate construction data, although they appear to be almostignored. The use of 3-D modeling systems is considered to be the most suitable vehicle for successfully integrating these data. However, this is likely to necessitate the introduction of separate databases, preferably of the relational type. The use of 3-D modeling systems in assessing the construction implications of outline designs also presents interesting possibilities and is discussed.

title	Knowledge-based Design Optimization
source	IAAI'86 Conference. 1986. pp. i:4:1-14
summary	CADLINE has abstract only. Optimization is a well understood process in design domains. A designer formulates the design problem as a single criterion or multicriteria optimization problem and then selects an appropriate optimization algorithm to search for the optimal values for the design variables. The formulation and algorithm selection procedures have been considered to be activities which relied on substantive human knowledge. This paper describes a computer system, OPTIMA, which formulates design optimization problems from a pseudo-English description into canonical algebraic expressions. It then recognizes the formulation and selects appropriate algorithm(s) for their solutions. Finally, it runs the selected algorithm(s) and sends the results to the original descriptions. Areas of expert knowledge involved in carrying out the above tasks are identified. Such knowledge is explicitly encoded in the systems. The basic philosophy and key features of the system are described and are illustrated by examples
