title	Computation-Universal Voxel Automata as Material for Generative Design Education
source	International Conference on Generative Art
summary	This paper is a report on the educational application of a voxel automata system for massively parallel execution of computation-universal cellular units in the generative design field. The software, designed and co-developed by the author to enable developmental strategies in generative design - for example with respect to 3D design generation, semantic self-evaluation and self-replication - was applied in teaching at the School of Design at The Hong Kong Polytechnic University to achieve two goals: to teach programming as part of the School’s Interactive Systems Design stream and to teach generative concepts at a theoretical, yet hands-on and highly intensive level. An introduction to the software, its development and its functions as well as a discussion of the teaching/learning experience is given, highlighting design educational aspects and student design work. The paper concludes with an analysis of how student approaches to generative concepts have been affected by the tool and how ideas and feedback from students have supported the ongoing development of the voxel automata system and its documentation.

title	BEYOND ANALYSIS AND REPRESENTATION IN CAD: A NEW COMPUTATIONAL APPROACH TO DESIGN EDUCATION
source	Submitted to the Department of Architecture in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the field of Architecture: Design & Computation at the Massachusetts Institute of Technology
summary	This thesis aims at changing students' attitude towards the use of computer-aided design (CAD) in architecture. It starts from the premise that CAD is used mostly for analysis and representation, and not as a real design aide, and that architecture students have a bias against learning computer programming. For this purpose, a prototypical instruction system that mixes computer-aided design and computational design theory was developed, based on a series of fundamental concepts that are common to both fields. This system was influenced by Mitchell's (1987) The Art of Computer Graphics Programming and Stiny's (1976) shape grammars. Despite being based on solid theoretical foundations, CAD has progressively become an exclusively practical tool, since its origins in the 50's and 60's, while computational design theories have been mostly restricted to the academic circles. This thesis proposes an inversion in the present situation: the study of CAD theory, and the application of computational design into practice. The system proposed provides a conceptual framework that can be adapted to different circumstances, including course formats and resources, as well as students' background and technical training. It is based on seven fundamental concepts from computational design theories that are also important to the study of shape grammars: symmetry, recursion, rule-based compositions, parameterization of shapes, generative systems, algorithmization of design procedures, and shape emergence. These concepts are introduced within a CAD context, where their practical implementation and experimentation are possible, focusing the understanding of the computational nature of design. During this research, the proposed system was tested in two case studies with students from schools that had contrary orientations in terms of the importance of CAD in the architectural curriculum. In these experimental courses, students' activities evolved from using a commercial CAD tool in an innovative way, to the use of programming techniques for creating meaningful tools. Despite not having a statistical reach, the fieldwork allowed drawing preliminary conclusions about the proposed system's efficacy, since virtually all the students reported changing their understanding of the role of CAD in architecture, while some also acknowledged a conceptual influence in other subjects and in the way they see architecture.

title	Ivy: Bringing a Weighted-Mesh Representations to Bear on Generative Architectural Design Applications
doi	https://doi.org/10.52842/conf.acadia.2016.140
source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 140-151
summary	Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.

title	Applied Generative Procedures in Furniture Design
source	International Conference on Generative Art
summary	This paper discusses an approach which combines different generative procedures with design methods as they are common in daily design practice: Two generative tools together with paper models, prototypes and „classical“ Computer Aided Design span the design process. The subject of experimentation is a specific class of furniture: CNC - manufactured, foldable objects for different seating positions, based on a material composition of thin plywood laminated with fabric and / or felt. The generative tools described below have been developed with the macro programming facilities of the CAD-software I-DEAS. One tool can be used either for systematic exploration of the search space or as a source for inspiration, depending on the preference settings chosen by the user. The other tool is made for the elaboration of details of the generated designs and for preparing production. The prototypes of these tools are still in an experimental stage and just in use to be tested and evaluated. Therefore the charcacter of the following text is more descriptive than analysing.

title	pCM (pure C Music): a real-time music language
source	International Conference on Generative Art
summary	In order to put to work the facilities offered by the gesture interfaces realised at cART project of CNR, Pisa, I started writing basic libraries for processing sound and for driving the gesture interfaces. In the long run the framework became a very efficient, stable and powerful “music language” based on pure C programming, that is “pure-C-Music”, or pCM. This programming environment gives the possibility to write a piece of music in terms of synthesis algorithms, score and management of data streaming from gesture interfaces. The pCM framework falls into the category of the “embedded music languages” and has been implemented using one of the most popular C compilers or better, multiplatform development systems: Metrowerks’ Code Warrior. As a result a pCM composition consists of a CW project which includes all the necessary libraries, including a DSP.lib consisting of a number of functions able to implement in real-time the typical synthesis and processing elements such as oscillators, envelope shapers, filters, delays, reverbs, etc. The composition itself is a C program consisting, mainly, of the Orchestra() and Score() functions. Everything here is compiled into machine code and runs at CPU speed.

title	Human-Artificial Ecosystems: Searching for a Language
source	International Conference on Generative Art
summary	The most recent advances of artificial life scientific research are opening up a new frontier: the creation of simulated life environments populated by autonomous agents. In these environments artificial beings can interact, reproduce and evolve [4, 6, 15], and can be seen as laboratories toexplore the emergence of social behaviors like competition, cooperation, relationships and communication [3, 5, 7] . It is still not possible to approach a reasonable simulation of the incredible complexity of human or animal societies, but these environments can be used as a scientific orartistic tools to explore some basic aspects of the evolution [1, 2, 3, 9, 11, 12, 13, 14, 15, 16].

title	Shared, Collective, Generative, Dynamic Virtual Environments - Geneve
source	International Conference on Generative Art
summary	In this project we plan to create an experimental novel medium setup for the study of the “presence” experience in shared, collective, generative, dynamic virtual environments (GENEVEs) in order to study the cross interactions between a given GENEVE and/among its creators/users and to explore the logic of presence in each GENEVE. The new shareable / generative media will try to add personal creativity and social dimension to telefruition of contents. For the European Industry having a leading edge in the technology for hw/sw/contents for shareable novel media is both a strategic asset and a social imperative.

title	Exploring Aesthetic Pattern Formation
source	International Conference on Generative Art
summary	This paper is an exploration of an interdisciplinary nature. Through studies in fine art, pattern formation in nature, and artificial life, a mechanism for the artistic process is presented. Asynchronous updating schemes implemented in cellular automata and pheromonal agent swarms were evolved to produce aesthetic patterns and compared favourably to non-evolved synchronous production methods. The curious adaptive properties of the resulting patterns were investigated.

title	GenJam in Transition: from Genetic Jammer to Generative Jammer
source	International Conference on Generative Art
summary	GenJam, short for Genetic Jammer, is an evolutionary computation (EC) based software agent that models a jazz improviser. Recently GenJam has evolved away from its roots as an interactive genetic algorithm toward its current state as an autonomous generative system. GenJam has retained its chromosome-based representations and mappings, its intelligent selection, crossover and mutation operators, and its real-time interactive performance capabilities. However, it no longer needs any explicit representation of fitness, which arguably makes it no longer an EC system. This paper considers GenJam as a generative art system. Generative art produces “unique and non-repeatable events” that express a designer’s generating idea. The designer’s generating idea defines a species of events, represented in a genetic code. In music, these events could be individual notes, melodic phrases, even entire pieces. In GenJam the events are four-measure phrases, or “licks” in the jazz vernacular. The format for the genetic code, then, defines a species space from which unique individual events can be generated. Uniqueness is important in jazz because improvisation must be spontaneous and “new.” Hence, improvisation is tailor-made for the generative art paradigm, and in fact, one could argue that improvisation is, by definition, the purest example of generative art applied to music. In other words, generative music is improvisation, and GenJam is the Generative Jammer.

title	A design optimization tool based on a genetic algorithm
source	Automation in Construction 11 (2) (2002) pp. 173-184
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 buildings.Genetic Algorithms (GAs) 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 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.

title	CAD – The Creative Side An educational experiment that aims at changing students’ attitude
source	International Conference on Generative Art
summary	The present paper describes an innovative design education system tried out at two different architecture schools in Brazil, with opposite approaches to the use of CAD. The experimental courses had two main goals: (1) to explore the use of logical operations in design, such as symmetry, recursion, parameterization, and combinatorial analysis, and (2) to apply these techniques with the use of the computers, using CAD not only as a representational tool, but rather as an explorative, customizable and programmable design aide for the creative process. The experiments resulted in a number of interesting compositions, design projects and programs, and assessment questionnaires revealed a real change in students’ attitude towards the use of CAD in architecture. The experiments related were the field research part of a Ph.D. thesis defended at MIT in July 2002. The present work had the support of CNPq, a Brazilian entity devoted to the scientific and technological development.

title	Design space navigation in generative design systems
source	Automation in Construction 11 (1) (2002) pp. 1-22
summary	Generative design systems make it easier for designers to generate and explore design alternatives, but the amount of information generated during a design session can become very large. Intelligent navigation aids are needed if designers wish to access the information they generate with ease. We present a comprehensive approach to support information navigation in requirement-driven generative design systems, which gain their power form explicit representations of design requirements, which in turn add to the information generated by the system. Our approach takes into account studies dealing with human spatial cognition, wayfinding in physical environments, and information navigation in electronic media. We structure the information to be accessed in terms of a five-dimensional design space model that applies across generative design systems of the type considered here. The model structure supports basic generic navigation operations along its five dimensions. We validated the model in the context of the SEED-Layout system and used it to extend the built-in navigation tools of the system through novel ones, which we subjected to a limited usability study. The study suggests that these tools have promise and warrant further investigation.

title	Generative Design: Rule-Based Reasoning in Design Process
source	International Conference on Generative Art
summary	As emphasized by Professor Soddu’s series of pioneer works on generative design, the fundamental theoretical base can be generallyconsidered as a design process that generates design by the initiation, developing and manipulation with designers’ objectives as well as theirassociated set of rules. This process is, in a broad sense, a reasoning process that follows the rules being set forth. In many cases, the rules arecommon logic that governs our reasoning, while in others they are more special rules that restrict the generating process to a confined space.Computer assisted generative design has made impressive progress over the past decade, along with the rapid growing capacity and speed ofcomputers as well as development and discovery of rules, rule setting and effective manipulating schemes and algorithms. After manyimpressive progress and remarkable results has demonstrated from time to time, however, theoretical foundation of such design approach, orthe significance of awareness of such approach has not been thoroughly treated, recognized and discussed, not to mention clearly understood.

title	An Informal Shape Grammars for Interpolations of Traditional Bosnian Hayat Houses in a Contemporary Context
source	International Conference on Generative Art
summary	This paper explores the use of an informal shape grammar method for Hayat house form interpolations. Interpolations are new house forms, which carry stylistic characteristics of an existing design language but are inserted into a context, which responds to a contemporary life style. The study is based on a corpus of eight Hayat houses designed in the classic Ottoman style in the 18th and 19th century in Sarajevo. The hayat is a large shaded gallery open to the garden. It occupies the most important place in the composition of the plan. In this study, a form-driven design strategy is applied. The emphasis is given to new house form generation. The generation of a new house form within the grammar proceeds in four steps: (1) Primitive hayat house generation, (2) sub-house generation, (3) House variations, (4) House development. The shape rules used in the process of hayat house interpolations are mostly informal and explain in general terms how certain parts of the form are modified.

title	Design devices: digital drawing and the pursuit of difference
source	Design Studies 23 (3) (2002) pp. 263-286
summary	We examine the uses of a prototypic device, in research and in design, for incorporating manual sketching into computer environments. We move from empirical and evolutionary conceptions of the role of such devices to the phenomenology of disclosure, attending to the revealing, generative, catalytic, metaphoric, signalling and provocative characteristics introduced by such devices. The discussion takes us through a series of steps that each amplifies the role of philosophical concepts of negation and difference in understanding the device.

title	GenOrchestra: An Interactive Evolutionary Agent for Musical Composition
source	International Conference on Generative Art
summary	GenOrchestra is a project involving the Dipartimento d’Informatica and Conservatorio di Musica “N. Piccinni” in Bari. This project concern a Creative Evolutionary System, based on Evolutionary Computation (EC) techniques, applied to the field of western tonal music. With GenOrchestra a novel way to evaluate the produced tunes is presented: indeed we adopt a hybrid solution composed for two kinds of fitness functions. The first, called technique fitness, evaluates the consonance degree between melodic, harmonic and rhythmic sections, moreover, it defines how well the rhythmic paths is organized into a coherent musical event. The second fitness function called human fitness, determine how well the tunes are perceived from a human audience, like in a concert. This task is accomplished by presenting the tunes on the Internet and then gathering the surfers evaluations in a database from which the system take the final population scoring. This, coupled with a no limited musical primordial soup, makes GenOrchestra a promising eclectic artificial composer. The ultimate goal of this project, currently in progress, is the development of a very human-like composer, which can produce music in any musical genre, and which is able to show a “personal style”. Samples will be soon available at http://valis.di.uniba.it/GenOrchestra/samples.html

title	Instance and System: a Figure and its 2.18 Variations
source	International Conference on Generative Art
summary	From the structural characteristics of an existing figure - a graphical logo – a plausible solution space of related figures is constructed, which contains all other figures, which may be generated by systematically exploiting the structural characteristics of the input figure. The constructed space of figures can be understood to represent the solution space for the design of the logo. A designer, proceeding systematically by following some generative set of rules would have to construct this solution space at least to the point of a decision, if not entirely. In the presented experiment, this “solution space” will be exhausted completely and the resulting images (there are 218 will be outputted graphically. Questions will be asked concerning the design process, the generative rules, and the selection of the one instance representing a solution. The presented results are to be seen as “work in progress”.

title	Interacting unities: an agent-based system
source	International Conference on Generative Art
summary	Recently architects have been inspired by Thompson’s Cartesian deformations and Waddington’s flexible topological surface to work within a dynamic field characterized by forces. In this more active space of interactions, movement is the medium through which form evolves. This paper explores the interaction between pedestrians and their environment by regarding it as a process occurring between the two. It is hypothesized that the recurrent interaction between pedestrians and environment can lead to a structural coupling between those elements. Every time a change occurs in each one of them, as an expression of its own structural dynamics, it triggers changes to the other one. An agent-based system has been developed in order to explore that interaction, where the two interacting elements, agents (pedestrians) and environment, are autonomous units with a set of internal rules. The result is a landscape where each agent locally modifies its environment that in turn affects its movement, while the other agents respond to the new environment at a later time, indicating that the phenomenon of stigmergy is possible to take place among interactions with human analogy. It is found that it is the environment’s internal rules that determine the nature and extent of change.
