title	Digital Morphogenesis and Computational Architectures
source	SIGraDi’2000 - Construindo (n)o espacio digital (constructing the digital Space) [4th SIGRADI Conference Proceedings / ISBN 85-88027-02-X] Rio de Janeiro (Brazil) 25-28 september 2000, pp. 98-103
summary	This paper examines methods in which digital media is employed not as a representational tool for visualization but as a generative tool for the derivation of form and its transformation - the digital morphogenesis. It explores the possibilities for the “finding of form”, which the emergence of various digitally based generative techniques seem to bring about. It surveys the digital generative processes - the computational architectures - based on concepts such as topological space, isomorphic surfaces, kinematics and dynamics, keyshape animation, parametric design, and genetic algorithms.

title	La Arquitectura como Extensión Fenotípica Humana - Un Acercamiento Basado en Análisis Computacionales [Architecture as human phenotypic extension – An approach based on computational explorations]

summary	The study describes some of the aspects tackled within a current Ph.D. research where architectural applications of constructive, structural and organization processes existing in biological systems are considered. The present information processing capacity of computers and the specific software development have allowed creating a bridge between two holistic nature disciplines: architecture and biology. The crossover between those disciplines entails a methodological paradigm change towards a new one based on the dynamical aspects of forms and compositions. Recent studies about artificial-natural intelligence (Hawkins, 2004) and developmental-evolutionary biology (Maturana, 2004) have added fundamental knowledge about the role of the analogy in the creative process and the relationship between forms and functions. The dimensions and restrictions of the Evo-Devo concepts are analyzed, developed and tested by software that combines parametric geometries, L-systems (Lindenmayer, 1990), shape-grammars (Stiny and Gips, 1971) and evolutionary algorithms (Holland, 1975) as a way of testing new architectural solutions within computable environments. It is pondered Lamarck´s (1744-1829) and Weismann (1834-1914) theoretical approaches to evolution where can be found significant opposing views. Lamarck´s theory assumes that an individual effort towards a specific evolutionary goal can cause change to descendents. On the other hand, Weismann defended that the germ cells are not affected by anything the body learns or any ability it acquires during its life, and cannot pass this information on to the next generation; this is called the Weismann barrier. Lamarck’s widely rejected theory has recently found a new place in artificial and natural intelligence researches as a valid explanation to some aspects of the human knowledge evolution phenomena, that is, the deliberate change of paradigms in the intentional research of solutions. As well as the analogy between genetics and architecture (Estévez and Shu, 2000) is useful in order to understand and program emergent complexity phenomena (Hopfield, 1982) for architectural solutions, also the consideration of architecture as a product of a human extended phenotype can help us to understand better its cultural dimension.

title	Artificial Worlds, Virtual Generations
source	International Conference on Generative Art
summary	The progress in the scientific understanding/simulation of the evolution mechanisms and the first technological realizations (artificial life environments, robots, intelligent toys, self reproducing machines, agents on the web) are creating the base of a new age: the coming of the artificial beings and artificial societies. Although this aspect could seems a technological conquest, by our point of view it represent the foundation of a new step in the human evolution. The anticipation of this change is the development of a new cultural paradigm inherited from the theories of evolution and complexity: a new way to think to the culture, aesthetics and intelligence seen as emergent self-organizing qualities of a collectivity evolved along the time through genetic and language evolution. For these reasons artificial life is going to be an anticipatory and incredibly creative area for the artistic expression and imagination. In this paper we try to correlate some elements of the present research in the field of artificial life, art and technological grow up in order to trace a path of development for the creation of digital worlds where the artificial beings are able to evolve own culture, language and aesthetics and they are able to interact con the human people.Finally we report our experience in the realization of an interactive audio-visual art installation based on two connected virtual worlds realized with artificial life environments. In these worlds,the digital individuals can interact, reproduce and evolve through the mechanisms of genetic mutations. The real people can interact with the artificial individuals creating an hybrid ecosystem and generating emergent shapes, colors, sound architectures and metaphors for imaginary societies, virtual reflections of the real worlds.

title	On the Translation of Design Data into Design Form in Evolutionary Design
source	International Conference on Generative Art
summary	The marriage of advanced computational methods and new manufacturing technologies give rise to new paradigms in design process and execution. Specifically, the research concerns itself with the application of Generative and Evolutionary computation to the production of mass-customized products and building components. The work is based on the premise that CAD-CAM should evolve into a dynamic, intelligent, multi-user environment that encourages creativity and actively supports the evolution of individual, mass-customized designs that exhibit common features. The concept of Parametric Design is well established, and chiefly concerns itself with generating design sets that exists within the boundaries of pre-set parametric values. Evolutionary Design extends the notion of parametric control by using rule-based generative algorithms to evolve common families of individual design solutions. These can be optimized according to particular criteria, or can form a wide variety of hierarchically related design solutions, while supporting design intuition. The integration of Evolutionary Design with CAD-CAM, in particular the areas of flexible manufacturing and mass-customization, creates a unique scenario which exploits the full power of both approaches to create a new design-process paradigm that can generate limitless possibilities in a non-deterministic manner within a variable search-space of possible solutions.This paper concerns itself with the technical and philosophical aspects of the codification, generation and translation of data within the evolutionary-parametric design process. The efficiency and relevance of different methods for treating design data form the most fundamental aspect within the realm of CAD/CAM and are crucial to the successful implementation of Evolutionary Design mechanisms. This begins at the level of seeding and progresses through the entire evolutionary sequence, including the codification for evaluation criteria. Furthermore, the integration of digital design mechanisms with CAM and CNC technologies requires further translation of data into manufacturable formats. This paper examines different methods available to system designers and discussed their effect on new paradigms of digital design methods.

title	Un Modelo Experimental em el Espacio-Tiempo de la Realidad Virtual (An Experimental Model in the Space-Time of Virtual Reality)
source	SIGraDi’2000 - Construindo (n)o espacio digital (constructing the digital Space) [4th SIGRADI Conference Proceedings / ISBN 85-88027-02-X] Rio de Janeiro (Brazil) 25-28 september 2000, pp. 251-253
summary	Virtual environments are a convergence between communicational media and computational capacities, that progressively integrate in interactive and global systems. This technological evolution has been progressively creating artificial contexts that find their latest and most integral expression in virtual environments. The influence of virtual worlds in our culture questions architecture, and arises the challenge of understanding the approach that should exist from architecture into virtual reality. This paper consists on an experimental exercise in virtual time-space oriented to the news information (News Information Centre), recognising that a relevant architectural event of our time is that virtual worlds represent a meeting between communicational technologies and the interest of contemporary society on being always informed (on line). This project is basically an exploration of virtual design that widens the professional field of architectural study, into the new technological and cultural challenges, that will probably influence significantly on the relations between architecture and urban culture.

title	A digital Procedure of Building Construction: A practical project
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

source	SIGraDi’2000 - Construindo (n)o espacio digital (constructing the digital Space) [4th SIGRADI Conference Proceedings / ISBN 85-88027-02-X] Rio de Janeiro (Brazil) 25-28 september 2000, pp. 383-387
summary	Technological innovations are driven in such dynamism, which do not favour a reflective process. Novelty is absorbed, in many cases, without criticism, in an immediate way. Concerning Architectural and Urbanism Education, a systematic reflection on the impact of new information technology to students training should not be omitted. As visual codes are the prime expression of architects, it is important to evoke the assumption of drawing as a language in order to evaluate it in regard to the new reality. Intending to broaden the discussion on these issues and to pose in theoretical means practical matters on didactics, it will be investigated the implications of computational resources - specially CAD systems - in graphic expression, in design thinking and their consequences to the education of future architects. Learning visual thinking, and being skillful at traditional as much as digital means, challenges today’s student.

summary	This paper presents a brief project process and representation techniques retrospective along the history, discussing the technologies used to support this process and evaluating its application, considering the practical needs and requirements that should be assisted by them in each moment of the humanity’s development, showing the interdependence relationship among the available project tools and the resultant products. It discusses a range of computational and information technologies that are potentially useful for the project process and could indeed contribute for the product improvement and for the process rationalization. The use of “new technologies” in the different phases and stages of the project process are discussed. Finally, it stands out the attention for the configuration of a new project language based in the massive use of computational technologies, as a tool capable to assist the current demands imposed by the society that comprehends: quality, productivity, competitiveness and others actual paradigms.

summary	The present article reports the experience of a Mastership/Doctorate class in the Production Engineering Postgraduation Program of Santa Catarina Federal University, with the finality of building a prototype of an educational software. The proposal was to facilitate hypermedia teaching, using hypermedia it self and starting from constructivism basements for the making of the project, named Building Hypermedia. The developed program enveloped pedagogically and operationally three phases: a navigation inside a given hypermedia, a feedback and a conscientization of the traveled way, and the possibility of making a singular hypermedia. The study is here presented on its essence, with the report of the work stages, the discrimination of the basic contents and the insertion of the main frames of the software. The objective is to show what results were reached and demonstrate the use and utility of hypermedia, as a computational mechanism with wide and diversified resources, mainly in teaching area.

summary	This paper surveys different approaches in contemporary architectural design in which digital media is used not as a representational tool for visualization but as a generative tool for the derivation of form and its transformation. Such approaches are referred to as digital architectures – the computationally based processes of form origination and transformations. The paper examines the digital generative processes based on concepts such as topological space, motion dynamics, parametric design and genetic algorithms. It emphasizes the possibilities for the “finding of form,” which the emergence of various digitally based generative techniques seem to bring about.

title	Travels in Space and Time, Explorations of Virtual SoundScapes, Multi-dimensionalism of Digital Music
source	International Conference on Generative Art
summary	Composition and performance of Computer Music still keep some of the features of traditional music, together with new ones. Rhythm, melody, harmony can still be present in new paradigms (even if they are not necessarily required when dealing with computer music), but new compositional parameters are coming to light, causing the term «music» not always to be appropriate to describe new phenomena of sonic art. This paper will show some new paradigms of this kind of sonic art, as well as different view of old ones. Any past dogmas should be wiped out when dealing with digital arts. The rebellion against tonality of the first half of 20th century is surpassed now, and I believe that new music could use harmonic intervals without generating conflicts with the ideological problems which arose at that time (even if there are still many people who don’t admit it). Actually, digital domain opens a huge amount of unexplored worlds, making any past ideological dogma a prison we should free ourselves from. Nowadays, making music has many things in common with visual arts and scientific research. Many musical parameters can be applied to video arts, architecture, and vice-versa. Structure of sound has a lot of similarities with many other physical phenomena such as inner atomic structure, particle physics, astronomy, biology etc. This paper will deal with new uses and interpretations of old musical parameters (rhythm, harmony, melody) together with a presentation of some of the new ones. Debated topics are: ? Harmonic/inharmonic sounds, rhythm and melodies. The Deep Harmony (the harmony of spheres or cosmic harmony CYCLES). ? The inner structure and evolution of a single sound ? Interpretative music: Music generated by exploration of soundscapes or sonic architectures, generative processes constrained by interpreter’s gestures, state transitions between musical structures. ? Generative music: stocastic generation, algorithmic composition, levels of action. ? Music or non-music this is the problem (a terminology problem) ? Hyper-spatial music, virtual times, hyper-times. Time travels by means of sonic matter. ? Visual music. Generating 3D video by means of musical processes.

summary	Fascinated by the possibility of designing the world, human being has always searched for tools to mediate this process. Cyberspace became one of this tools. Virtual technologies associated to communicational technologies are changing human’s cultural, social, and material context, consequently changing the idea of architecture itself. The decreasing material content of our activities and their increasing perceptual, communicative and cognitive contents are drawing a new framework to our spatial experiences. Objects, spaces, buildings and institutions can now be constructed, navigated, experienced and manipulated across cyberspace. The particular focus in this paper is to discuss the architectural aspects of the Virtual Architectures (VAs) and an initial framework for its design.

summary	With the rise of the digital in architecture and the availability of digital fabrication tools, the interest in the material aspect of the model has intensified. At the same time, the design space for exploration of material behavior and its design potential has been extended from the physical into the digital. This has resulted in a cyclic set of translations from the physical realm into the digital by means of mathematical descriptions and back from the digital realm into the physical by means of digitally controlled fabrication processes. Despite the availability of more and more computational power and improvement of precision in simulation, these translations from the physical into the digital and vice versa can never be exact (Eco 2006), the translations from the physical model into a digital model and from the digital into the physical are "spaces of instability" (Evans 2000). The current paper explores in more detail this space of instability between physical and digital models, its potential for architectural design, and the central role of the mathematical description in this reciprocal set of translations.

summary	The study investigates learning and pedagogical differences between using physical models and computational simulations for architectural lighting design studies. The vehicle of the study is a real life architectural project for a church building. The research reveals that users of physical models were more aware of the need for technical knowledge whilst the users of simulation software are more contended with the virtual results without evaluating them critically. Preliminary results not only confirm the long established view that the computational simulation lacks the tactile quality for architectural understanding; worst still, it gives inexperienced users illusions of knowledge and claims of understanding. To further validate the results, works involving a larger sample set and a more comprehensive design program should be conducted.

summary	This paper provides a state-of-the-art of computational fluid dynamics (CFD) in the building industry. Two methods were used to find this new knowledge: a series of interviews with leading architecture, engineering, and software professionals; and a series of tests in which CFD software was evaluated using comparable criteria. The paper reports findings in technology, workflows, projects, current unmet needs, and future directions. In buildings, airflow is fundamental for heating and cooling, as well as occupant comfort and productivity. Despite its importance, the design of airflow systems is outside the realm of much of architectural design practice; but with advances in digital tools, it is now possible for architects to integrate air flow into their building design workflows (Peters and Peters 2018). As Chen (2009) states, “In order to regulate the indoor air parameters, it is essential to have suitable tools to predict ventilation performance in buildings.” By enabling scientific data to be conveyed in a visual process that provides useful analytical information to designers (Hartog and Koutamanis 2000), computer performance simulations have opened up new territories for design “by introducing environments in which we can manipulate and observe” (Kaijima et al. 2013). Beyond comfort and productivity, in recent months it has emerged that air flow may also be a matter of life and death. With the current global pandemic of SARS-CoV-2, it is indoor environments where infections most often happen (Qian et al. 2020). To design architecture in a post-COVID-19 environment will require an in-depth understanding of how air flows through space.

summary	This paper describes our initial efforts to deploy a digital library to support computer-aided collaborative design. At present, this experimental testbed, The EngineeringDesign Knowledge Repository, is an effort to collect and archive public domain engineering data for use by researchers and engineering professionals. We envision thiseffort expanding to facilitate collaboration and process archival for distributed design and manufacturing teams.CAD knowledge-bases are vital to engineers, who search through vast amounts of corporate legacy data and navigate on-line catalogs to retrieve precisely the rightcomponents for assembly into new products. This research attempts to begin addressing the critical need for improved computational methods for reasoning about complexgeometric and engineering information. In particular, we focus on archival and reuse of design and manufacturing data for mechatronic systems. This paper presents adescription of the research problems, an overview of the initial architecture of the testbed and a description of some of our preliminary results on conceptual design anddesign retrieval.

summary	Supporting data sharing among different disciplines, applications, and users in the building industry is a complex and difficult task. Standardization efforts and research into product models have since long attempted to facilitate data exchange among building partners, with little result so far. Different technologies have resulted in different approaches, in particular, an object-oriented approach has led to the specification of IFCs as a basis for information sharing, while other initiatives adopt XML as a flexible language for marking up and describing project information. We propose a concept for representational flexibility, named sorts, that combines many of the advantages of both approaches. Based on an extensible vocabulary of representational classes and compositional relationships and grounded in an object-oriented framework that has each of the representational classes specify its own operational behavior, it will enable a designer to define, develop, and adopt alternative design representations that can suit a specific purpose or task at hand.

summary	By surveying a total of 55 cutting-edge architectural design offices (mostly in the United States), this paper looks at the use of computational media to get an overall understanding of its current use for architectural design presentation. The intent of this paper is to highlight the changing direction of computer presentation through graphic examples, specifically three-dimensional modelling that goes beyond conventional representation. The paper also illustrates various types of uses of computer media by designers into specific categories, and extracts a summary of hardware and software preferences.

title	Visualisation and simulation with object-oriented networks
source	Eindhoven University of Technology
summary	Among the existing systems, visual programming environments address best these issues. However, producing interactive simulations and visualisations is still a difficult task. This defines the main research objective of this thesis: The development and implementation of concepts and techniques to combine visualisation, simulation, and application construction in an interactive, easy to use, generic environment. The aim is to produce an environment in which the above mentioned activities can be learnt and carried out easily by a researcher. Working with such an environment should decrease the amount of time usually spent in redesigning existing software elements such as graphics interfaces, existing computational modules, and general infrastructure code. Writing new computational components or importing existing ones should be simple and automatic enough to make using the envisaged system an attractive option for a non programmer expert. Besides this, all proven successful elements of an interactive simulation and visualisation environment should be provided, such as visual programming, graphics user interfaces, direct manipulation, and so on. Finally, a large palette of existing scientific computation, data processing, and visualisation components should be integrated in the proposed system. On one hand, this should prove our claims of openness and easy code integration. On the other hand, this should provide the concrete set of tools needed for building a range of scientific applications and visualisations. This thesis is structured as follows. Chapter 2 defines the context of our work. The scientific research environment is presented and partitioned into the three roles of end user, application designer, and component developer. The interactions between these roles and their specific requirements are described and lead to a more precise formulation of our problem statement. Chapter 3 presents the most used architectures for simulation and visualisation systems: the monolithic system, the application library, and the framework. The advantages and disadvantages of these architectural models are then discussed in relation with our problem statement requirements. The main conclusion drawn is that no single existing architectural model suffices, and that what is needed is a combination of the features present in all three models. Chapter 4 introduces the new architectural model we propose, based on the combination of object-orientation in form of the C++ language and dataflow modelling in the new MC++ language. Chapter 5 presents VISSION, an interactive simulation and visualisation environment constructed on the introduced new architectural model, and shows how the usual tasks of application construction, steering, and visualisation are addressed. In chapter 6, the implementation of VISSION’s architectural model is described in terms of its component parts. Chapter 7 presents the applications of VISSION to numerical simulation, while chapter 8 focuses on its visualisation and graphics applications. Finally, chapter 9 concludes the thesis and outlines possible direction for future research.
