summary This project involves the creation of an architecture of music which may be defined as a series of interdisciplinary steps which seek to generate four-dimensional virtual spaces for the materialization of music. This materialization uses music as its .genetic information ., the virtual space as its medium, and the execution time of the musical piece as the fourth dimension to a three-dimensional virtual space. Within this space, each instrument.s execution is represented by a shape whose properties undergo changes resulting from the musical information. Through the use of new Virtual Reality techniques, we will soon have the possibility to be inside the music, as a habitable place. The achievement of this project is to provide the opportunity to experience this representation through virtual animation.

title Behavior-based Computational Design Methodologies: Integrative processes for force defined material structures
source ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 82-89
summary With the introduction of physics-based algorithms and modeling environments, design processes have been shifting from the representation of materiality to the simulation of approximate material descriptions. Such computational processes are based upon enacting physical and material behavior, such as gravity, drag, tension, bending, and inflation, within a generative modeling environment. What is often lacking from this strategy is an overall understanding of computational design; that information of increasing value and precision is generated through the development and iterative execution of specific principles and integrative mechanisms. The value of a physics-based modeling method as an information engine is often overlooked, though, as they are primarily utilized for developing representational diagrams or static geometry – inevitably translated to function outside of the physical bounds and parameters defined with the modeling process. The definition of computational design provides a link between process and a larger approach towards architecture – an integrative behavior-based process which develops dynamic specific architectural systems interrelated in their material, spatial, and environmental nature. This paper, focusing on material integration, describes the relation of a computational design approach and the technical framework for a behavior-based integrative process. The application is in the development of complex tension-active architectural systems. The material behavior of tensile meshes and surfaces is integrated and algorithmically calibrated to allow for complex geometries to be materialized as physical systems. Ultimately, this research proposes a computational structure by which material and other sorts of spatial or structural behaviors can be activated within a generative design environment.

summary One of the primary features of solar passive design is the orientation of a building on a particular latitude. The client of Information Technology demands testing, validity, practicality and sustainability of a building project before execution. The computer based simulations are the only practical way to predict the complex energy performance and analysis for a large number of passive design solutions. This paper investigates the optimum residential building orientation having various zones, located in Lahore, Pakistan, with the help of Energy Simulation program. It is concluded that with the help of software, it is possible to orient the residential plan with the minimum solar gain of the required living zones.

title An integrated system for computer-aided design and construction of reinforced concrete buildings using modular forms
source Automation in Construction 5 (4) (1996) pp. 323-341
summary The study reported in this paper investigates the feasibility of automating the on-site construction of reinforced concrete residential buildings. The basic construction tasks are identified, analyzed and modified with a view towards potential for automation. Emphasis is placed on developing modular forms that facilitate automation. The majority of work in the field of construction robotics has focused on the adaptation of existing industrial robots to automate traditional construction processes. This paper outlines a computer-aided construction system approach specially suited for integrating design and implementation by on-site robots. A Computer-Integrated Construction (CIC) system, similar to CIM, is developed that includes a CIC data-base, a construction design system, a construction production/process planning system, and a robotics execution system. This approach is intended to minimize the redesign effort as well as the need for on-site manual work.

summary Platforms that integrate developments from multiple disciplines are becoming increasingly relevant as the complexity of different technologies increases day by day. In this context, this paper describes an integrative approach for the development of architectural projects. It portrays the benefits of applying such an approach by describing its implementation throughout the development and execution of a building demonstrator. Through increasing the agility and extending the scope of existing computational tools, multiple collaborators were empowered to generate innovative solutions across the different phases of the project´s cycle. For this purpose, novel solutions for planar segmented wood shells are showcased at different levels. First, it is demonstrated how the application of a sophisticated hollow-cassette building system allowed the optimization of material use, production time, and mounting logistics due to the modulation of the parameters of each construction element. Second, the paper discusses how the articulation of that complexity was crucial when negotiating between multiple professions, interacting with different contractors, and complying with corresponding norms. Finally, the innovative architectural features of the resulting building are described, and the accomplishments are benchmarked through comparison with typological predecessor.

title Touch, See, Make: Employing Active Touch in Computational Making

summary In architectural education and practice, we don’t come in physical contact with what we make until the later stages of the design process. This vision-oriented approach to design is something deeply rooted in architectural practice: from Alberti’s window to the screens of our computers, design has traditionally been more of a visual and less of a hands-on process. The vision of the presented study is that if we want to understand the way we make in order to improve tools for computational design and making, we need to understand how our ability to make things is enhanced by both our visual and tactile mechanisms. Bringing the notion of active touch from psychology into the design studio, I design and execute a series of experiments investigating how seeing, touching, or seeing and touching exhibit different sensory competencies, and how these competencies are expressed through the process of making. The subjects of the experiment are asked to tactilely, visually, or tactilely and visually observe a three-dimensional object, create descriptions of its composition, and to remake it based on their experience of it using plastic materials. After the execution of the experiment, I analyze twenty-one reproductions of the original object; I point to ways in which touch can detect scale and proportions more accurately than vision, while vision can detect spatial components more efficiently than touch; I then propose ways in which this series of experiments can lead to the creation of new design and making tools.

title How Architects Draw with Computers: A Cognitive Analysis of Real-World CAD Interactions
source Carnegie Mellon University, School of Architecture and School of Computer Science
summary New media throughout history have passed through a period of transition during which users and technologists took many years to understand and exploit the medium's potential. CAD appears to be passing through a similar period of transition; despite huge investments by vendors and users, CAD productivity remains difficult to achieve. To investigate if history can provide any insights into this problem, this thesis begins with an examination of well-known examples from history. The analysis revealed that, over time, users had developed efficient strategies which were based on powers and limitations of tools; delegation strategies exploited powers provided by tools, and circumvention strategies attempted to overcome their limitations. These insights on efficient strategies were used to investigate the CAD productivity problem based on four research questions:

1. How do architects currently use CAD systems to produce drawings?

2. What are the effects of current CAD usage on product and performance?

3. What are the possible causes of current CAD usage?

4. What are the capabilities of the CAD medium and how can they be used efficiently?

The above four questions were addressed through the qualitative, quantitative, and cognitive analysis of data collected during an ethnographic study of architects working in their natural environment. The qualitative and quantitative analysis revealed that users missed many opportunities to use strategies that delegated iteration to the computer. The cognitive analysis revealed that missed opportunities to use such delegation strategies caused an increase in execution time, and an increase in errors many of which went undetected leading to the production of inaccurate drawings. These analyses pointed to plausible cognitive and contextual explanations for the inefficient use of CAD systems, and to a framework to identify and teach efficient CAD strategies. The above results were found to be neither unique to the CAD domain, nor to the office where the data were collected. The generality of these results motivated the identification of seven claims towards a general theory to explain and identify efficient strategies for a wide range of devices. This thesis contributes to the field of architecture by providing a detailed analysis of real-world CAD usage, and an approach to improve the performance of CAD users. The thesis also contributes to the field of human-computer interaction by demonstrating the generality of these results and by laying the framework for a general theory of efficient strategies which could be used to improve the performance of users of current and future computer applications.

title CAAD in the Transformability Evaluation of Historical Buildingsof Historical Buildings
source Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 55-58
summary In the execution of a research, which was intended to identify methods and instruments for transformability evaluation of historical buildings, CAAD was usefully employed in the decision-making process at different levels. From an operative point of view, it was fundamental instruments for the acquisition of typomorphological data inherent to pre-existent buildings. It allowed us to create an archive of information which can be easily and flexibly up-dated. In fact the critical evaluation of these buildings is based on the identification of structural patterns which have characterized the typological evolution of the urban structure, and thus the different historical stratifications have to be carefully catalogued, profoundly analyzed and compared one with the other. CAAD was even more effective during the phase of meta-designing checking concerning the choices effected for conversion of old buildings, since it was possible to prefigure different scenarios according to formulated hypotheses and this gave us the opportunity to evaluate their effective practicability in relation to typo- morphological congruence and logical and formal connection between the old building and new design proposals.

summary The research paper exemplifies a novel information integrated design technique developed at ONL (Oosterhuis and Lenard), Netherlands, specifically appropriated for envisaging complex geometric forms. The ‘informed design technique’, apart from being highly instrumental in conceptualizing and generating the geometric component constituting architectural form in a parametric manner, is also efficiently utilized for precise computer aided manufacturing and construction of the speculated form. Geometric complexities inherent in contemporary architectural constructs and the time spent in appropriation of such topologies, fueled the ‘informed design’ approach, which caters to issues of timely construction, precision oriented design and production (visual and material) and parametric modeling attuned to budgetary fluctuations. This design-research approach has been tested and deployed by ONL, for conceiving ‘the Acoustic Barrier’ project, Utrecht Leidsche Rijn in the Netherlands and is treated as a generic case for exemplifying the ‘informed design’ technique in this research paper. The design methodology encourages visualizing architectural substantiations from a systems perspective and envisages upon a rule based adaptive systems approach involving extrapolation of contextual dynamics/ground data in terms of logical ‘rules’. These rules/conditionalities form the basis for spawning parametric logistics to be mapped upon geometric counterparts exemplifying the conception. The simulated parametric relations bind dimensional aspects (length, width, height etc.) of the geometric construct in a relational manner, eventually culminating in a 3D spatial envelope. This evolved envelope is subsequently intersected with a ‘parametric spatio-constructive grid’, creating specific intersecting points between the two. The hence extorted ‘point cloud’ configuration serves as a generic information field concerning highly specific coordinates, parameters and values for each individual point/constructive node it embodies. The relations between these points are directly linked with precise displacements of structural profiles and related scaling factors of cladding materials. Parallel to this object oriented modeling approach, a detailed database (soft/information component) is also maintained to administer the relations between the obtained points. To be able to derive constructible structural and cladding components from the point cloud configuration customized Scripts (combination of Lisp and Max scripts) process the point cloud database. The programmed script-routines, iteratively run calculations to generate steel-wireframes, steel lattice-structure and cladding panels along with their dimensions and execution drawing data. Optimization-routines are also programmed to make rectifications and small adjustments in the calculated data. This precise information is further communicated with CNC milling machines to manifest complex sectional profiles formulating the construct hence enabling timely and effective construction of the conceptualized form.

summary Robosense 2.0: Robotic Sensing and Architectural Ceramic Fabrication demonstrates a generative design process based on collaboration between designers, robotic tools, advanced software, and nuanced material behavior. The project employs fabrication tools which are typically used in highly precise and predetermined applications, but uniquely thematizes the unpredictable aspects of these processes as applied to architectural component design. By integrating responsive sensing systems, this paper demonstrates real-time feedback loops which consider the spontaneous agency and intuition of the architect (or craftsperson) rather than the execution of static or predetermined designs. This paper includes new developments in robotics software for architectural design applications, ceramic-deposition 3D printing, sensing systems, materially-driven pattern design, and techniques with roots in the arts and crafts. Considering the increasing accessibility and advancement of 3D printing and robotic technologies, this project seeks to challenge the erasure of materiality: when mistakes or accidents caused by inconsistencies in natural material are avoided or intentionally hidden. Instead, the incorporation of material and user-input data yields designs which are imbued with more nuanced traces of making. This paper suggests the potential for architects and craftspeople to maintain a more direct and active relationship with the production of their designs.

title Automatic generation of the controlling-system for a wall construction robot
source Automation in Construction 5 (1) (1996) pp. 15-21
summary In this article we present several important aspects of a software system control. This is designed and developed for a wall assembly robot in an European Esprit III project called ROCCO, RObot assembly system for Computer integrated COnstruction. The system consists of an off-line program for planning of complex assembly tasks and for generating robot actions. The execution is controlled through an adaptive user interface and gives the user the possibilities to switch in an on-line mode command. All the software is designed with the object-oriented concept and implemented in C + +. The wall assembly system is organized on the base of the successive generation of different types of actions, called "Mission", "Task", and "Action". They represent different levels of assembly complexities. Those different actions are organized in a tree structure. Furthermore, the software system can be connected to a CAD-robot simulation software for checking the robot assembly motions. Added to the control system, a recovery module has been implemented for all possible errors during the construction. First the OO-model of the world and of robot activities will be presented. Secondly, several aspects of the algorithm will be explained and at the end we will show the strategy used for the robot motion.

title A Generative Approach to Variations in Production Processes
source International Conference on Generative Art
summary Many work procedures in generating various types of products (such as execution of recipes for food, work operation for leather, procedures for conservation of vegetables, factory workmanship processes, etc) are characterised by precise procedural steps. Each step can be defined, at the proper detail level, in terms of kind of operations, input conditions, output results; then, a complete procedure can be exploited as a set of partially ordered steps of such a kind of functions. The formalisation of such a steps allows to evaluate procedures devoted to the same goal, introducing metrics for comparing them in terms of originality or imitation. Furtherly, a contextual analysis of different procedures devoted to similar goals allows to verify possible variations in the procedures, introducing innovation and changes on the basis of the available examples. The changes can be automated through proper algorithms, just using techniques of learning by examples, in the respect of verifiable constraints. The results can be verified, and used again as a new enriched experienced basis to improve the innovation procedures. The paper will describe the approach for the analysis and the description, will propose an experienced metric, and will show examples of generation of new innovative methods based on the automated analysis of successful examples. All the practical examples will be expressed in cooking recipes, described, compared in terms of plagiarism with properly defined metrics, improved with automatic generation based on experience and examples, properly checked and validated.

title Microcomputer-Based Expert System for the Design of Operational Military Airfields
source Department of Architectural Science, University of Sydney
summary This thesis develops a number of prototypical expert systems on a microcomputer to assist the military designer or engineer with facets of military operational airfield design. An existing expert system shell BUILD written in PROLOG-1 was altered to provide a more permanent record of the results of the system execution. The individual knowledge base includes production rules which conform to the BUILD syntax requirements. A number of additional clauses related to the knowledge base are written in PROLOG-1. The expert system consists of some 200 rules and an additional 36 clauses. The rules contain knowledge on soil characteristics pertinent to airfields, factors involved in calculating lengths of runways and factors for determining the effort involved in construction. The knowledge for the expert systems was gathered from a combination of civilian and military literature sources, the author's own experience, and discussions with military and air force personnel currently engaged in the design, planning and construction of these facilities. Development of these prototypical expert systems demonstrates the feasibility of implementing expert systems on microcomputers in this domain. Furthermore, it demonstrates their possible application to military engineering design particularly where the design process relies on a large amount of tabulated data and heuristic knowledge. It is this type of knowledge that is often used by the military engineer to find a timely problem solution when provided with a range of options. [Unpublished. -- CADLINE has abstract only.]

title Towards a Comprehensive User Interface Management System

summary A UIMS developed at the University of Toronto is presented. The system has two main components. The first is a set of tools to support the design and implementation of interactive graphics programs. The second is a run-time support package which handles interactions between the system and the user (things such as hit detection, event detection, screen updates, and procedure invocation), and provides facilities for logging user interactions for later protocol analysis. The design / implementation tool is a preprocessor, called MENULAY, which permits the applications programmer to use interactive graphics techniques to design graphics menus and their functionality. The output of this preprocessor is high- level code which can be compiled with application-specific routines. User interactions with the resulting executable module are then handled by the run-time support package. The presentation works through an example from design to execution in a step-by-step manner

title Cunning Crafts or Poetic Place-Making? Towards a Historiography of Generative Art
source International Conference on Generative Art
summary This paper begins by considering the meaning and relationship between generativity and art. From there an historical analysis of these terms maps out the philosophical terrain of generative art in practice and theory. It is hypothesized that the degree to which a generativity, or birthing, may be understood as inherent in art understood as a poetic making, is the degree to which the term generative becomes a redundant qualifier of the term art. An argument is then made that art and art-making as a poetic production has an ethical vocation to critique its sources and its media in order to imagine worlds where the marginalized other, as other, is received. As a result, the unqualified adoption of computer, machine, biologicalor chemical media, as well as the mathematic or pragmatic instructions that define the execution of their works, needs to be questioned.I conclude with an historiographical examination of the Babylonian abacus and the medieval ars memoritiva, in particular, Ramon Lull’s 1274 figura universalis. Even though computing historians have claimed these as proto-computers, a deeper examination of their meaning, use and context reveal a fundamentally mimetic vocation that provides the possibility of poetic place-making, as an ethics, which is otherwise absent in thecontemporary microprocessor. The question is therefore raised whether the works presented at “generative art” galleries, websites and conferences such as this may make any claim to poetry, ethics or art per se if their use of mathematics and automation remains uncritical.

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 Registering visual permeability in architecture: Isovists and occlusion maps in AutoLISP
source Environment and Planning B: Planning and Design 37(6): 1128–1136
summary In this paper the design and execution of a simple AutoLISP routine for generating a map of plan isovists (in the sense of Benedikt) are discussed. Such a plan field of isovists is a registration of visibility from multiple station points within and around a building. More precisely, the plan field records the cumulative effect, over a spatial matrix, of occluded vision of a distant horizon. Thus, the plan field is termed an occlusion map. An occlusion map registers the effect which an observer's position in space has on their perception of architecture's visual permeability. Occlusion maps are shown here to be an important tool for comparing existing buildings in a historical sense and also as an effective design tool, particularly when an addition to an existing building is being contemplated, as an addition invariably affects the visual permeability of its host.

In fact, when designing complicated building assemblies by making use of common graphical representations, it might be impossible for the operator to choose the proper shape and installation sequence of components so that they do not interfere during the assembly, and to check, in the meantime, the most favorable setting up modalities according to execution problems. Our software, running within CAD, by starting from the definition of the node features, will allow the operator to automatically get three types of representation that can simulate the assembly according to the assigned installation sequence: - instant images of the phases for setting up each component into the node; - 3D views showing the position of each component disassembled from the node and indicating the movements required for connection; - the components moving while the node is being constructed. All the representations can be updated step by step each time modifications to the node are made. Through this digital iterative design process - that takes advantage of various simultaneous and realistic prefigurations - the shape and function compatibility between the elements during the assembling can be verified. Furthermore, the software can quickly check whether any change and integration to the node is efficacious, rising the approximation levels in the design phase. At the moment we have developed the part of the tool that simulates the assembly by moving the components into the nodes according to the installation sequence.

summary In these years the researches on the computer science applied to the building have had a considerable development. The applications concern the whole design process, from the programming to the design and from the execution control to the programmed maintenance with a great deal of problems solved using expert systems. It doesn't seem that the same care of men and means has been dedicated to the architectural design theory, to its deep roots which motivate it and to its peculiarity in comparison with other fields in which now the design, with the aid of the computer, is the only one possible. The designer of architectural objects has been always helped by design assistants: it is enough to think that the sixteenth century treatises are a group of rules, descriptions, solutions to design problems and that they represent the "knowledge" of the age. As the knowledge increased those treatises amplified to the encyclopaedic dimensions of the nineteenth-century handbooks and of those of the first years of this century, while new professional figures rose, the teaching developed and the building art became more and more complex.
