title	Generative Polymodal Music Process
source	International Conference on Generative Art
summary	We present underlying ideas used to develop an Algorithmic Composition software named KYKLOS. It was designed to generate music based on generalised musical scales and modes. It is an interactive sonic device to be applied in composition as well in performance. The sonic output of the whole process can be described as generalised polymodal music since “synthetic scales” are generated by the algorithm. This environment can be used in a Computer Assisted Composition manner in order to generate MIDI files. On the other hand, it can equally be used as a performance environment in which a dynamic change of parameters enables a real time control of the sonic process. Recently, we advocated that several mathematical applications in Computer Music can be understood as Sound Functors [1]. In extension, we describe here a sound functor used to model scales and modes. As can be verified, part of early investigations on mathematical structures in music studied musical scales and modes using Combinatorics, Fibonacci Series and Golden Mean in order to understand compositional processes which use modal concepts. Using the Functor definition it is possible to enumerate n-scales as a sequence of integers. Each value in that sequence gives the distance (in half tones) between two consecutive tones. For example, the sequence 3:2:2:3 is interpreted as a pentatonic scale C-Eb-F-G-Bb, and as defined above it is a C mode. So, if we apply cyclical permutations, (n-1)-sequences of numbers should be interpreted as n-modes of tones. Our algorithmic implementation is described briefly. A n-mode is defined as an array with n-1 integers [a1, a2, ...an-1]. Each array generated at k-th step can be read as a number a1a2a3 ....an-1 in decimal representation, where ai is a integer between 1 and 9. We denote the number obtained at k-th step as (a1a2a3 ...an-1)(k) . The rules to implement the algorithm are the following:1) V0 = (1, 1, 1, 1 ......,1) (initial n-mode)2) ? ai ? 11 with i= 1, 2...n-1 (octave range constraint)3) Vk = (a1a2a3 ...an-1)(k) < (b1b2b3 ...bn-1)(k+1) = Vk+1 where aj ?bj , 1? j ? n-1.4) Vmax = (13 – n, 1, 1, ...,1)In this paper we start with a theoretical view and an introduction on the algorithmic mechanism used. Further, we present a concept of man ? machine interaction used to create the composition environment. We also describe the compositional graphic interface developed and general functions of the system. Finally there is a set of music examples generated by KYKLOS as MIDI files.

summary	The projectual disciplines must respond with some grade of originality to a approached problem. In order to products of design be creative must be implemented a creative process of design and also from the teaching. The essence of creativity are the variations over a subject. A pedagogic way for this, is the one to recognise, individualise and represent the problem attributes, building upon them an "exploration space", to analyse and create new combinatorial alternatives or restructuring of the problem. The digital media incorporation as a new proyectual environment approaches the interactivity not only of the combinatorial variables, but, also to the hypermedia's. Both the digital documents, as the creative process, have a "no linear" or a "net" structure, that allows the construction of a himself way, self-managemented into this structure. The interactivity makes possible to work, as the divergent thought does, in a "polydirectional" field, that stimulates the fluency, the flexibility and the originality. The new- media's, used as didactic tool, open to "action", allow the students to convert them in "co- author", together professors, about themself learning process. >From this educational conception and its potential enrichment with the hypermedia, we are designing a project of digitising of an exercise to our didactic proposal and its later application into the course with our students.

summary	This paper presents an application of swarm intelligence towards the problem of spatial configuration. The methodology classifies activities as discrete entities, which self-organise topologically through associational parameters: an investigation of emergent route formation and spatial connectivity based on simple agent and pheromone interaction, coupled with the problem of ‘loose’ rectangular geometric assembly. A concept model sniffingSpace (Ireland, 2009) developed in Netlogo (Willensky, 1999), which established the self-organising topological capacity of the system, is extended in Processing (Fry & Rea, 2009) to incorporate rectangular geometry towards the problem of planning architectural space.

title	Illumination distribution from brightness in shadows: adaptive estimation of illumination distribution with unknown reflectance properties in shadow regions
source	Proceedings IEEE Conference on Computer Vision and Pattern Recognition 99, pp. 875-882, September 1999
summary	This paper describes a new method for estimating the illumination distribution of a real scene from a radiance distribution inside shadows cast by an object in the scene. First, the illumination distribution of the scene is approximated by discrete sampling of an extended light source. Then the illumination distribution of the scene is estimated from a radiance distribution inside shadows cast by an object of known shape onto another object in the scene. Instead of assuming any particular reflectance properties of the surface inside the shadows, both the illumination distribution of the scene and the reflectance properties of the surface are estimated simultaneously, based on iterative optimization framework. In addition, this paper introduces an adaptive sampling of the illumination distribution of a scene. Rather than using a uniform discretization of the overall illumination distribution, we adaptively increase sampling directions of the illumination distribution based on the estimation at the previous iteration. Using the adaptive sampling framework, we are able to estimate overall illumination more efficiently by using fewer sampling directions. The proposed method is effective for estimating an illumination distribution even under a complex illumination environment.

title	Virtual Reality in Architectural Education: Defining Possibilities
source	ACADIA Quarterly, vol. 18, no. 4, pp. 7-9
doi	https://doi.org/10.52842/conf.acadia.1999.007
summary	Introduction: virtual reality in architecture Virtual Reality (VR) is an emergent computer technology for full 3D-simulations, which has a natural application in the architectural work, due that activity involves the complete definition of buildings prior to its construction. Although the profession has a long tradition and expertise in the use of 2D-plans for the design of buildings, the increasing complexity of projects and social participation requires better media of representation. However, the technological promise of Virtual Reality involves many sophisticated software and hardware developments. It is based on techniques of 3D-modelling currently incorporated in the majority of drawing software used in architecture, and also there are several tools for rendering, animation and panoramic views, which provide visual realism. But other capabilities like interactivity and sense of immersion are still complex, expensive and under research. These require stereoscopic helmets, 3D pointers and trackers with complicated configurations and uncomfortable use. Most advanced installations of Virtual-Reality like CAVEs involve much hardware, building space and restrictions for users. Nevertheless, diverse developers are working in Virtual-Reality user-friendly techniques and there are many initial experiences of architectural walk-throughs showing advantages in the communication and development of designs. Then we may expect an increasing use of Virtual Reality in architecture.

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.

source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 186-191
summary	This text makes a careful description of a great part of the components of the vocabulary of architecture and their syntax. It's structured in two parts, one textual and the other graphic. Due to the acknowledged contribution of the author on the subject of description of vocabulary of the elements of architecture and the research and development works that are entered upon in the master in computer graphics in the informatic field, it was proposed the development of an interactive system that allowed by means of links to connect the different parts of text and their respective graphics. Having as a basis the idiomatic equivalent term in Spanish and English, carried out in another research work, it was considered the possibility to link the text in these two languages besides the original one, french. That's why we've decided to propose the navigation through numeric text and images. This navigation has been already inferred from the reading of the text as intended from the author's that was why our task has been the interpretation of this intention and its translation in an informatic system. The product presented in this work is limited to having designed a methodology and showing its performance with some terms and images, able to make evident the sketch of our idea. The work is made out of the description of the following phases: 1.) Design of its interface; 2.) Compilation and classification of images compilation and classification of text; 3.) Coordination of textual and graphic elements; 4.) Programming of events in the interactive system.

summary	Assisting to the urgent necessity of documenting buildings, urban and rural spaces of our district and keeping in mind that, this patrimonial values represent a considerable proportion of the creative and constructive effort of the pioneers of this region and of our memory and identity, you urgent restitution the report of the examples that are still conserved. As well as the reconstruction, in the cases that it was necessary, of the missing patrimony that still stays in the collective memory. The construction of the digital inventory outlines, in a principle; to divide to the city in sectors of different urban-architectural importance the hills of. Santa Cecilia Stala Maris and Divino Rostro, those that still conserve numerous examples of architecture of the past, are an example of it. This documentation is carried out from the entity of culture of the municipality of the district of general Pueyrredón, in function of the activity developed in the area of patrimonial preservation. In what concerns to this work, previous antecedents don't exist in our means, being this the first time that is intruded in the land of the digital graph applied to the investigation and historical documentation.

summary	The insert of the digital technologies in the atmosphere Áulico has left generalizing in a significant way. An example constitutes it the high percentage of students that they manifested general knowledge in the software handling in the introductory course of visual communication, as well as the voluntary presentation of practical works developed with digital means. The necessity of an answer to the requirements that arise of the students sinks to the certainty of a pedagogic compatibility among the matter to try and the teaching attended by the personal computer that would increase the Iconidad and the understanding of a topic of certain complexity like it is the geometry of the space. An educational program designed for the teaching of the Sistema Monge whose general characteristics were presented in the II Ibero-American Seminar of Digital Graph and that it will be applied as experience pilot in the course 2000, it will allow us to respond to the following queries: what place it will be given to the educational program in the formation process in connection with the other pedagogic means.

summary	Much interest has been recently devoted to generative processes in design. Advances in computational tools for design applications, coupled with techniques from the field of artificial intelligence, have lead to new possibilities in the way computers can inform and actively interact with the design process. In this paper we use the concepts of generative and goal-oriented design to propose a computer tool that can help the designer to generate and evaluate certain aspects of a solution towards an optimized behavior of the final configuration. This work focuses mostly on those aspects related to the environmental performance of the building. Genetic Algorithms are applied as a generative and search procedure to look for optimized design solutions in terms of thermal and lighting performance in a building. The Genetic Algorithm (GA) is first used to generate possible design solutions, which are then evaluated in terms of lighting and thermal behavior using a detailed thermal analysis program (DOE2.1E). The results from the simulations are subsequently used to further guide the GA search towards finding low-energy solutions to the problem under study. Solutions can be visualized using an AutoLisp routine. The specific problem addressed in this study is the placing and sizing of windows in an office building. The same method is applicable to a wide range of design problems like the choice of construction materials, design of shading elements, or sizing of lighting and mechanical systems for buildings.

source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 171-175
summary	This piece proposes new strategies and pedagogic methodologies applied to the recognition and study of the subjacent measurements of the architectural projects to be created. This proposal is the product of pedagogic experience, which stems from this instructional team of the department of tri-dimensional models of electronic models. This program constitutes an elective track for the architectural major at the college of architecture, design, and urbanism of the University of Buenos Aires and housed at the CAO center. One of the requirements that the students must complete, after doing research and analytical experimentation through the knowledge that they acquired through this course, is to practice the attained skills through exercises proposed by the department in this case, the student would be required to virtually rebuild a paradigmatic architectonic piece of several sample architects. Usually at this point, students experience some difficulties when they analyze the existing documents on the plants, views, picture, details, texts, etc., That they have obtained from magazines, books, and other sources. Afterwards, when they digitally begin to generate basic measurements of the architectural work to be modeled, they realize that there are great limitations in the comprehension of the tri-dimensional understanding of the work. This issue has brought us to investigate and develop proposals of volumetric understanding of patterns through examples of work already analyzed and digitalized tri-dimensionally in the department. Through a careful study of the existent documentation for that particular work, it is evaluated which would be the paths and basis to adopt through utilizing alternative technologies to arrive at a clear reconstruction of the projected architectural work, the study gets completed by implementing the proposal at the internet site http://www.datarq.fadu.uba.ar/catedra/dorcas

summary	This work presents the study and applied assays (or simulation tests) about the ordination of urban space in the region of Lagoa da Conceição. In the region pressures placed by the growth of urban area and urban network system are in contact conflict with a fragile ecosystem, and with a sustainable development based on tourism. Analysis procedures exploited different forms of Space Syntax trying to examine effects of spatial structure in relation to movement patterns of pedestrians and vehicles. This methodology allowed the comprehension of relation between spatial configuration, transport and soil use, and reveled the interdependence and performance of built space within the restrict regional scale (Lagoa da Conceição) and the total urban structure of the island. This understanding is not limited to the present. Is also includes the study of historic urban evolution, and simulation of existing projects for the future, being an important tool to support project decision process. Consequently, the obtained results bring a new approach for the problem, which makes possible the synthesis of design proposals verifying its implications and consequences.

doi	https://doi.org/10.52842/conf.caadria.1999.243
summary	This paper intends to explore methods of constructing a design simulator. Two methodologies, approached differently, imitate the human design processes. The first component is an algorithmic method which has a cognitive model embedded. This cognitive model hypothesizes that human design has certain design logic applied. The design rationales are based on knowledge stored in a designer_ memory. Each time a similar design task is encountered, the same design procedures will be repeated for completion. What makes the results different are the design information used and sequences of processing it. A kitchen design using procedural algorithms is developed to simulate this design aspect. The second component simulates an intuitive design approach. Intuition is defined as design by rules of thumb, or heuristic design. This study investigated how to simulate an intuitive design process. The method involves building up a set of inductive rules symbolizing cultural aspects that need to be addressed in a design. A residential foyer design is the simulation task. The driving force is the heuristics. Results in this study have shown that there are many variables to include but impossible to capture and simulate any of the design processes, which are the reasons why studies in this area are difficult.

summary	University of Oregon Architecture Department has developed a spectrum of digital design from introductory methods courses to advanced design studios. With a computing curriculum that stresses a variety of tools, architectural issues such as form-making, communication, collaboration,theory-driven design, and presentation are explored. During the first year, all entering students are required to learn 3D modeling, rendering, image-processing and web-authoring in our Introduction to Architectural ComputerGraphics course. Through the use of cross-platform software, the two hundred beginning students are able to choose to work in either MacOS or Windows. Students begin learning the software by ‘playing’ with geometric elements and further develop their control by describing assigned architectural monuments. In describing the monuments, they begin with 2D diagrams and work up to complete 3D compositions, refining their modelswith symbol libraries. By visualizing back and forth between the drafting and modeling modes, the students quickly connect orthogonal plans and sections with their spatial counterparts. Such connections are an essential foundation for further learning.

doi	https://doi.org/10.52842/conf.ecaade.1999.151
summary	Our collective concept of computing and its relevance to architecture has undergone dramatic shifts in emphasis. A review of popular texts from the past reveals the biases and emphases that were current. In the seventies, architectural computing was generally seen as an elective for data processing specialists. In the early eighties, personal computers and commercial CAD systems were widely adopted. Architectural computing diverged from the "batch" world into the "interactive" world. As personal computing matured, introductory architectural computing courses turned away from a foundation in programming toward instruction in CAD software. By the late eighties, Graphic User Interfaces and windowing operating systems had appeared, leading to a profusion of architecturally relevant applications that needed to be addressed in introductory computing. The introduction of desktop 3D modeling in the early nineties led to increased emphasis upon rendering and animation. The past few years have added new emphases, particularly in the area of network communications, the World Wide Web and Virtual Design Studios. On the horizon are topics of electronic commerce and knowledge markets. This paper reviews these past and current trends and presents an outline for an introductory computing course that is relevant to the year 2000.

summary	This paper treats of the management of the position of objects on the plane. At first sight problems related with planning objects on the plane appear to be quite trivial. Nevertheless a system able to manage the permutation of objects the one with respect to the others becomes a complex one when all the possible variations are taken into account. The operations to be performed include topological variations in a combinatorial process. Although the results of such a system could be of general design application in this paper only architectural problems are examined as examples. In the first part an outline of the system is presented. In the second part a computer program directed to produce graphical results is described together with some case studies.

title	A Virtual Reality User Interface for a Design Information System, CCAI: the Journal for the Integrated Study of Artificial Intelligence
source	Cognitive Science and Applied Epistemology, Rijks Universiteit Gent
summary	The computer is a tool, a complex artefact that is used to extend our reach. A computer system can provide several kinds of services, but against these services stands a supplementary task that the user must deal with: the communication with the computer system. We argued that Virtual Reality (VR) can fundamentally improve the user interface by rendering on the common experiential skills of all users. We present the theoretical basis for this, referring to Donald Norman's theory. We show that VR provides at least theoretically, the means to take a big step in the direction of an ideal user interface. As an example of a innovative application of VR in user interface design, we presented the VR-DIS system; an interdisciplinary design system for the building and construction industry. We discuss the issues underlying the design of its VR interface.
