title Freeform Surfaces Adaptation through Developable Surfaces Using Apparent Contours
source Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 358-367.
summary Free-form surfaces construction has been limited to the possibilities of graphical and constructive control. In a few years we have seen an important development of control of the form through digital graphic technology, software and hardware that allowed truly spectacular constructions. A significant researching way not only in architecture, but also in engineering even in sculpture, has been the adaptation of free forms through developable surfaces using different systems, many based on differential geometry. Reinterpreting some topics of projective geometry that allows the use of certain CAD software, jumping from the physical to the digital drawing system, has been developed a method allows the adaptation of free forms through developable surfaces using apparent contours that we can draw over these free form surfaces. Trough using them we can trace two types of developable surfaces as cones and cylinders that are touching the surface tangentially to this contours.

summary We imagine the buildings of a not too distant future (constructions that we will inhabit) as the combination of digital design, additive manufacturing, advanced robotics, sensors, transmitters, information in the cloud, information of networks, information of other robot networks, etc. all interconnected and with autonomous response. We imagine the skin as a biomimetic envelope of autonomous response to environmental changes. We perceive that skin, or the envelope of the architectural construction made with personalized products, a physical object created by printing layer by layer of a three-dimensional model or 3D digital drawing, an additive manufacturing or 3D printing. We do not rule out that this physical object can be printed in 4D in a process in which the skin itself or envelope built by a process linked to advanced robotics and AI can generate products that modify themselves to respond to changes climatic.

title Structure and Flow of Design Information in the Construction Process
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary At every step in the construction process different individuals (architects, engineers, project managers and workmen) make use of design information, yet the requirements they have for the contents and structure of this information are radically different. This paper makes some general observations on the structure, productions and manipulation of design information, concentrating specifically on the form in which information is passed between individuals, the relationship between graphic and text based information, and the interaction between design information and materials flows in the constructions supply chain. On the basis of these observations, this paper presents a general conceptual framework for describing the information flow with the aim of understanding and controlling it. Within this framework, some conceptual tools are proposed thatcan be used to structure design information including abstraction, dependent relationships, and control and identify hierarchies. Next, this paper illustrates how one company, Matura Nederland, has used these concepts and tools to develop design processes and computer software to integrate its operational process from design to installation. Finally, some suggestions are made as to how these ideas relate to some current developments in CAD, database and process control software.

title Overcoming Repetition: Robotic fabrication processes at a large scale
source International Journal of Architectural Computing vol. 11 - no. 3, 285-300
summary In the context of the Future Cities Laboratory (FCL) of ETH Zurich, the Professorship for Architecture and Digital Fabrication of Fabio Gramazio and Matthias Kohler has set up a robotic laboratory to investigate the potentials of non-standard robotic fabrication for high rise constructions in Singapore. The high degree of industrialisation of this dominant building typology implies standardisation, simplification and repetition and accounts for the increasing monotony evident in many Asian metropolises. The aim of this research on material systems for robotic construction is to develop a new and competitive construction method that makes full use of the malleable potential of concrete as a building material. A novel, spatial, robotic "weaving" method of a tensile active material that simultaneously acts as the form defining mould, folds two separate aspects of concrete-reinforcement and formwork-into one single robotic fabrication process (see Figure 1). This in-situ process could permit the fabrication of structurally differentiated, spatially articulated and material efficient buildings.

title Mesh Mould: Differentiation for Enhanced Performance
source Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 139–148
summary Mesh-Mould is a novel robotic fabrication system for complex, non-standard concrete structures. The system folds together formwork and reinforcement, the two most labour intensive aspects of concrete constructions and offers an alternative approach to the current modes of prefabrication by suggesting an in-situ fabrication process (Figure 1). The paper outlines the development of the Form-work/Reinforcing Meshes through several iterations of physical and digital tests. Initially starting from simple triangulated 3D lattices, the structures evolved to become more complex and differentiated. The incorporating of flow enhancing ducts and surface perimeters with diverse surface aperture densities facilitates an optimal concrete flow and material distribution within the mesh.

summary The deconstruction (DeCon) and repurposing (ReCon) of existing structures and materials are worthwhile and relevant endeavors given the potential for such procedures to be more economically and environmentally sustainable than conventional construction methods. Conventional construction methods often utilize virgin materials for the production of architecture, requiring extensive energy to harvest, process, and manufacture the materials for use. Today, we must face the fact that we exist in a carbon-sensitive economy, and demand design approaches that reduce architecture’s impact on the environment. Our goal was to develop a CADCAM ReCon design methodology that would have the potential to mitigate carbon consumption. To explore this goal, students engaged a design research project that looked for novel and innovative approaches to the DeCon and ReCon of an existing barn. The student researchers created parametric models and surface designs derived from the existing materials. The digitally fabricated tectonic design constructions resulted in economical, novel, and material-efficient design methodologies for DeCon and ReCon.

title Visual Intelligence
source Norton Publishing, New York
summary After his stroke, Mr. P still had outstanding memory and intelligence. He could still read and talk, and mixed well with the other patients on his ward. His vision was in most respects normal---with one notable exception: He couldn't recognize the faces of people or animals. As he put it himself, "I can see the eyes, nose, and mouth quite clearly, but they just don't add up. They all seem chalked in, like on a blackboard ... I have to tell by the clothes or by the voice whether it is a man or a woman ...The hair may help a lot, or if there is a mustache ... ." Even his own face, seen in a mirror, looked to him strange and unfamiliar. Mr. P had lost a critical aspect of his visual intelligence. We have long known about IQ and rational intelligence. And, due in part to recent advances in neuroscience and psychology, we have begun to appreciate the importance of emotional intelligence. But we are largely ignorant that there is even such a thing as visual intelligence---that is, until it is severely impaired, as in the case of Mr. P, by a stroke or other insult to visual cortex. The culprit in our ignorance is visual intelligence itself. Vision is normally so swift and sure, so dependable and informative, and apparently so effortless that we naturally assume that it is, indeed, effortless. But the swift ease of vision, like the graceful ease of an Olympic ice skater, is deceptive. Behind the graceful ease of the skater are years of rigorous training, and behind the swift ease of vision is an intelligence so great that it occupies nearly half of the brain's cortex. Our visual intelligence richly interacts with, and in many cases precedes and drives, our rational and emotional intelligence. To understand visual intelligence is to understand, in large part, who we are. It is also to understand much about our highly visual culture in which, as the saying goes, image is everything. Consider, for instance, our entertainment. Visual effects lure us into theaters, and propel films like Star Wars and Jurassic Park to record sales. Music videos usher us before surreal visual worlds, and spawn TV stations like MTV and VH-1. Video games swallow kids (and adults) for hours on end, and swell the bottom lines of companies like Sega and Nintendo. Virtual reality, popularized in movies like Disclosure and Lawnmower Man, can immerse us in visual worlds of unprecedented realism, and promises to transform not only entertainment but also architecture, education, manufacturing, and medicine. As a culture we vote with our time and wallets and, in the case of entertainment, our vote is clear. Just as we enjoy rich literature that stimulates our rational intelligence, or a moving story that engages our emotional intelligence, so we also seek out and enjoy new media that challenge our visual intelligence. Or consider marketing and advertisement, which daily manipulate our buying habits with sophisticated images. Corporations spend millions each year on billboards, packaging, magazine ads, and television commercials. Their images can so powerfully influence our behavior that they sometimes generate controversy---witness the uproar over Joe Camel. If you're out to sell something, understanding visual intelligence is, without question, critical to the design of effective visual marketing. And if you're out to buy something, understanding visual intelligence can help clue you in to what is being done to you as a consumer, and how it's being done. This book is a highly illustrated and accessible introduction to visual intelligence, informed by the latest breakthroughs in vision research. Perhaps the most surprising insight that has emerged from vision research is this: Vision is not merely a matter of passive perception, it is an intelligent process of active construction. What you see is, invariably, what your visual intelligence constructs. Just as scientists intelligently construct useful theories based on experimental evidence, so vision intelligently constructs useful visual worlds based on images at the eyes. The main difference is that the constructions of scientists are done consciously, but those of vision are done, for the most part, unconsciously.

summary From the analysis of the project of preservation and rehabilitation of the “groupe scolaire” Karl Marx (1932) in Villejuif designed by André Lurçat, it was possible to bring into light the existence of a corpus of homogenous constructions, which unfortunately did not receive a fair recognition until today. It consists in a group of elementary schools – nursery and primary – designed and built during the 1929 -1939 decade, located in close Paris’ suburb, and among which most of them keep their original purpose today. Regrettably, their vicissitudes altered their image and actual perception, and consequently their meaning escapes us, their importance, what they can communicate to us as testimonies of a period of strong ideological conflicts, where the claimed modernity of these buildings seemed to announce the freeing of the man from class struggle. The aims of this study are to question about the value of this heritage, to try to bring out its meaning and to envision which would be the mechanisms that should allow modifying its actual blurred and wrong perception.

summary The CONSTRUCTS Toolkit is a wireless sensor network system (WSN) for mixed - reality applications. Wireless sensor networks have become an accessible development platform with advances in the convergence of micro electro - mechanical systems technology, wireless communication protocols, integrated circuit technologies, and pervasive and embedded systems. As applied applications for wireless sensor networks in the manufacturing and health industries continue to grow there remains an opportunity to integrate these technologies into gaming and learning applications. This paper will present an overview of the CONSTRUCT/VisM application designed for transforming construction state messages from the WSN CONSTRUCTS Toolkit into a real - time 3D virtual environment.

summary To animate is to give life or motion to an object. In this study, the method for exploring in four dimensions was the use of animation in a three dimensional model; the objects were well known paintings or drawings. Although architectural studies were encouraged, a range of paintings was chosen and different intentions about the role of animation were investigated.

title The Geometrical Structure of new Architectural Object - The role of meta-mechanics of Holography in its formation
source Odysseas Kontovourkis (ed.), Sustainable Computational Workflows [6th eCAADe Regional International Workshop Proceedings / ISBN 9789491207143], Department of Architecture, University of Cyprus, Nicosia, Cyprus, 24-25 May 2018, pp. 29-38
keywords In recent years there has been a gradually increasing interest in the terms on which the design and geometrical representation of the architectural object is based. ?he true challenge lies in the development of a methodology or mechanism which, having as its starting point the traditional object geometrical representation practices, will allow for a combination of new technologies towards creating new visual messages. In this research, the process of putting together a new architectural object, the digital hologram, will be seen as one such mechanism. The new views and strategies on space are open to treating spatial constructions, as a restructuring of the structures that could bring about changes for more favorable conditions for the representation of the architectural form. Thus, the strategies of architectural pioneering are judged by their ability to develop new procedures that are capable of reversing.

title Transducer: 3D Audio-Visual Form-Making as Performance
source AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999, pp. 285-291
summary This paper describes Transducer, a prototype digital system for live, audio-visual performance. Currently the process of editing sounds or crafting three-dimensional structures on a computer remains a frustratingly rigid process. Current tools for real-time audio or visual construction using computers involve obtuse controls, either heavily GUI'ed or overstylized. Transducer asks one to envision a space where the process of editing and creating on a computer becomes a dynamic performance. The content of this performance may be sufficiently complex to elicit multiple interpretations, but Transducer enforces the notion that the process of creation should itself be a fluid and transparent expression. The system allows a performer to build constructions of sampled audio and computational three-dimensional form simultaneously. Each sound clip is visualized as a "playable" cylinder of sound that can be manipulated both visually and aurally in real-time. The transducer system demonstrates a creative space with equal design detailing at both the construction and performance phase.

title Architectural Interpretation of Cellular Automata
source International Conference on Generative Art
summary Mathematical constructions and concepts can be utilized in a number of methods to investigate the process of generating architectural forms. One is to technically layout architectural elements along such constructions, another is to explicitly develop forms corresponding exactly to the underlying concept, and another is to use such concepts as inspiration, a starting point for design. A hybrid method is to follow an interpretive approach, one that uses a mathematical concept as a framework to begin to investigate architecture forms. Architectural considerations are applied both at the beginning of the process and continually throughout the process as a better understanding of the underlying concept is developed. This paper attempts to use cellular automata is such a way. The process of investigating such concepts, it is believed, will help other such approaches, as well as, more traditional approaches of design development.

title Growth of spatial network constructions: a decision support systems oriented approach
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary The paper describes a method that has been developed to be used in a process for a systematic search of alternative designs for a network configuration. In the design process we will take into account that we may not be able to implement the full configuration all at once. Logical partial configurations must be derived. The process can than also be used to investigate the expansion of (railroad) networks. The basic idea is that either the most profitable trajectories or the trajectories that contribute most to the improved quality of the configuration will be developed first. A method cannot incorporate all criteria that are relevant for the final decision simultaneously, one of the reasons being that not all criteria are suitable for a mathematical formulation. Therefore a method cannot be used to replace current legal and political procedures. However it can be considered to be part of a decision support system that could be used in a preliminary investigation preceeding such procedures. In the example presented in this paper the criteria and calculations are kept simple for illustrative purposes. However they can easily be made more complex and realistic without damaging the fundamental concepts of the search algorithm. If the system is implemented in a way that the criteria to be used in the selection process can be chosen in interaction with the decision maker (or moderator) one can truly speak of a decision support system for the project formulation phase for the construction of the physical network. In the algorithm the network is represented as a graph and the nodes connected by the network are termed centers of attraction, supply and demand.

summary The rapid growth of complex contemporary architecture design, contributed by the advance in parametric CAD/CAM software, is accompanied by challenges in the production process; it demands both highly trained workers and technical equipments. This paper reviews current technologies in robotics-aided construction and wearable computers for generic purposes, and proposes the design of a robotic device for construction guidance. It guides the user, the worker, through the assembly process of precision modular constructions, by providing procedural mechanical or haptic assistance in the 3-dimensional positioning of building components. The device is designed to be wearable, portable, and operable as a completely stand-alone system that requires no external infrastructure. A prototype of the device is tested with a mock-up masonry construction experiment, the result of which is reported in this paper, along with discussion for future improvement and application opportunities within the context of highly developed, condensed Japanese urban environments. A greater objective of this paper is to bridge current studies in Human-Computer Interaction (HCI) and digital fabrication in architecture and promote the potentials of human workers in future construction scenes.

summary Good visualization mechanisms offer architects, and their clients, a better grasp of how their designs are going to turn out when built, and the experience one might have inside the constructions. This also helps the architect orient the design in a more informed manner. However, typically used modeling tools do not offer satisfactory visualization solutions. The operations available to view and navigate through the 3D space are flawed in terms of speed, interactivity, and real-time rendering quality. To solve this issue, we propose the coupling of a portable algorithmic design framework with a Game Engine (GE) to support interactive visualization of architectural models and increase the rendering performance of the framework. We explain in detail this integration, and we evaluate this workflow by implementing a case study and comparing the performance of the GE to architectural modeling tools.

summary The topic of this paper is to describe the ability of 3D CAD systems to integrate designers and engineers into a simultaneous process developing a functional and aesthetic concept in a close and equal interdisciplinary process. We already have the Finite Element Method, FEM systems for analyzing the mechanical behavior of constructions. This technique is suitable for justifying design aspects in the final part of the design process. A new group of CAE systems under the generic term Topology optimizing has the potentials to handle aspects of conceptual design and aesthetic criteria. Such interactive design tools do not eliminate the designer, but the relationship between the designer and other professions and the professional consciousness of the designer will change. It is necessary to develop common ideas able to connect the scientific and the artistic fields. The common aesthetic values must be clarified and the corresponding formal ideas be developed. These tools could be called "Construction tools for the intelligent user" (Olhoff, 1998) because the use of optimizing is based on a profound knowledge of the techniques.

Gehry, born in 1929, founded his own architectural firm in Los Angeles in 1962, and since the building of the Guggenheim Museum in Bilbao, he is undoubtedly among the ranks of international architecture superstars. His buildings are complex constructions, with curves and distortions, skilful plastic shapes which never cease to surprise with their breath-taking spatial effects. To create these daring designs, Gehry makes extensive use of the latest electronic tools, physical models are transformed into digital models using software and hardware which has been adapted from the space industry and medical research. This book provides a colourful insight into Gehry's design methods and the creative process behind his fantastic buildings.
