title	A Primitive-Instancing Interactive 3-D Modeling System for Spatial Design Studies
source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 457-468
summary	The authors have developed a basic, interactive, primitive-instancing 3-D modeling system (CAADF), which is based on a high-speed 3-D color graphic workstation, and have tested its potential ability to support spatial design studies in an architectural design studio. After- a review of work performed by a student with the system, this paper concludes that this system provides an attractive environment for spatial design studies which conventional CAD systems have not achieved. The interactive process of 3-D modeling in perspective or isometric view images and the dynamic viewing utility are the most successful features of the system. In contrast to those advantages, the resolution of color graphic display is a limitation of the system. The authors conclude that if sufficiently many appropriate 3-D geometric primitives are supported by a CAD system, a primitive instancing method can significantly reduce the work entailed in object modeling.

summary	While the development of modeling and drafting tools for computer-aided design has reached a state of considerable maturity, computerized decision support in architectural sketch design is still in its infancy after more than 20 years. The paper analyzes the difficulties of developing computer tools for architectural problem solving in the early stages of design where decisions of major importance are made. The potentials of computer methods are discussed in relation to design as a static system of information and to design as a dynamic creative process. Two key problems are identified, and on this background current computer methods intended for use in architectural sketch design are critically reviewed. As a result some guidelines are suggested for future research into computer- aided architectural problem solving. The purpose of the paper is twofold: (1) to encourage research that will take this field into a state of maturity and acceptance by practitioners, and (2) to provoke further debate on the question of how to do it.

title	Archaeological Site Reconstruction With AutoDesk's 3D Studio
source	CSA Newsletter Vol 7:3 Nov 1994
summary	3D Studio is an IBM-compatible computer modeling program that enables users to create three-dimensional renderings of a variety of objects. In its ability to import a wide variety of maps and other images, 3D Studio allows for the realistic rendering of models created within AutoCAD or other 3D CAD packages. Over the past year, the Homol'ovi research program has been utilizing this software to create near photo-realistic renderings of conjectural site models. My own interests in three-dimensional computer modeling developed out of work at the site of Homol'ovi IV, a 150-room pueblo site located near Winslow, Arizona. The site was situated upon a steep 30-meter bluff with a bedrock cap. Approximately 24 rooms were located on top of the bedrock cap, with another 125 rooms situated on the slope of the butte. During the 1989 field season five structures were excavated, while a separate crew worked clearing and mapping the tops of walls. Mapping was accomplished with a Topcon EDM/theodolite station, and a standard map was created from this process. (See Fig. 3.) While the map was sufficient to show the general layout of the site, I remained unsatisfied; a 2D plan view simply did not convey the vertical dimension of the pueblo. At this point the Homol'ovi Research Program purchased a copy of AutoCAD in order to begin exploring three-dimensional mapping and modeling.

title	A Contrast in Pedagogy: The M.l.T. Versus Harvard Approach to Computer Aided Design
source	CAAD: Education - Research and Practice [eCAADe Conference Proceedings / ISBN 87-982875-2-4] Aarhus (Denmark) 21-23 September 1989, pp. 5.1.1-5.1.9
doi	https://doi.org/10.52842/conf.ecaade.1989.x.d8b
summary	This is a period of relative detente among academics in the field of computers and architecture, advocating the use of computers in a design studio is today received more politely than, as in the past, when it was received like a declaration of war. Among some research groups at M.I.T. and Harvard to first engage In this field, the approaches were so dissimilar to one another that they could be considered as constituting separate schools of thought. Over time, however, a number of paths have led to a similar direction, if not agreement among principal investigators. The lack of sharply competing ideologies today may be a little less exciting: however, the enormous growth of the academic discipline seems now to allow for a fruitful exchange of ideas between positions that no longer seem mutually exclusive. Two views are important, among others, at M.I.T. and Harvard. The classic M.I.T. view looks upon the AI Lab as a microcosm for examining how architects think. Underlying this view is the position of 'lets examine the way architects think about design and build tools which can reflect that process'. Another point of view, as expressed at Harvard, is speculative on what architects seem to do in design practice and education, rather than speculative on the nature of thinking per se. Both views seem ultimately to be concerned with representing architectural design knowledge within computers. And in the rob of computers as a design medium. This paper examines how the M.I.T. view and the Harvard view have superficially been associated with separate research directions. As these contrasting points of view incorporate many common themes. The author finds that it may be possible to take an eclectic position in teaching computer aided design.

title	A Comprehensive Approach to the Tensile Structures Design

summary	We present an integrated set of programs as CAD-tools for the design of shapes, evaluation of stress field and displacements of tensile membrane structures as well as a way to find out their surface patterns. In early times simulation of physical small models has been used to obtain a phenomenological view rather than quantitative information about these structures. A progressive way has been thought to make a comprehensive an practical approach to this kind of structure, characterized by its ability to offer displacements of long range. We propose like a first steep a rough simulation through elastic member models or elastic-surface models. An iterative process starts, based on visualizations through different peripheric devices (screened and plottered graphic outputs). This first steep ends by the formulation of an optimum geometric performances of the structure. The resulting geometry serves like a source structure for a more accurate calculus achieved by the Finite Element Method. Discretization of the continues structure is carried out in a network of tiny triangular elements. Finally, 3-D realism techniques has been used to represent the form adopted or stress field calculated or both at the same time, by an adequate use of the color attributes of the finite elements.

title	The visual harmony between new and old materials in the restoration of historical architecture: A study of computer simulation
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 the research of historical architecture restoration, scholars respectively focus on the field of architectural context and architectural archeology (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000) or on architecture construction and the procedure of restoration (Shi, 1988, 1989; Chiu, 1990). How to choose materials and cope with their durability becomes an important issue in the restoration of historical architecture (Dasser, 1990; Wang, 1998).In the related research of the usage and durability of materials, some scholars deem that, instead of continuing the traditional ways that last for hundreds of years (that is to replace new materials with old ones), it might be better to keep the original materials (Dasser, 1990). However, unavoidably, some of the originals are much worn. Thus we have to first establish the standard of eliminating components, and secondly to replace identical or similar materials with the old components (Lee, 1990). After accomplishing the restoration, we often unexpectedly find out that the renewed historical building is too new that the sense of history is eliminated (Dasser, 1990; Fu, 1997). Actually this is the important factor that determines the accomplishment of restoration. In the past, some scholars find out that the contrast and conflict between new and old materials are contributed to the different time of manufacture and different coating, such as antiseptic, pattern, etc., which result in the discrepancy of the sense of visual perception (Lee, 1990; Fu, 1997; Dasser, 1990).In recent years, a number of researches and practice of computer technology have been done in the field of architectural design. We are able to proceed design communication more exactly by the application of some systematic softwares, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and so on (Lawson, 1995; Liu, 1996). The application of computer technology to the research of the preservation of historical architecture is comparatively late. Continually some researchers explore the procedure of restoration by computer simulation technology (Potier, 2000), or establish digital database of the investigation of historical architecture (Sasada, 2000; Wang, 1998). How to choose materials by the technology of computer simulation influences the sense of visual perception. Liu (2000) has a more complete result on visual impact analysis and assessment (VIAA) about the research of urban design projection. The main subjects of this research paper focuses on whether the technology of computer simulation can extenuate the conflict between new and old materials that imposed on visual perception.The objective of this paper is to propose a standard method of visual harmony effects for materials in historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example).There are five steps in this research: 1.Categorize the materials of historical architecture and establish the information in digital database. 2.Get new materials of historical architecture and establish the information in digital database. 3.According to the mixing amount of new and old materials, determinate their proportion of the building; mixing new and old materials in a certain way. 4.Assign the mixed materials to the computer model and proceed the simulation of lighting. 5.Make experts and the citizens to evaluate the accomplished computer model in order to propose the expected standard method.According to the experiment mentioned above, we first address a procedure of material simulation of the historical architecture restoration and then offer some suggestions of how to mix new and old materials.By this procedure of simulation, we offer a better view to control the restoration of historical architecture. And, the discrepancy and discordance by new and old materials can be released. Moreover, we thus avoid to reconstructing ¡§too new¡¨ historical architecture.

title	Toward a procedure of computer simulation in the restoration of historical architecture
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 the field of architectural design, “visualization¨ generally refers to some media, communicating and representing the idea of designers, such as ordinary drafts, maps, perspectives, photos and physical models, etc. (Rahman, 1992; Susan, 2000). The main reason why we adopt visualization is that it enables us to understand clearly and to control complicated procedures (Gombrich, 1990). Secondly, the way we get design knowledge is more from the published visualized images and less from personal experiences (Evans, 1989). Thus the importance of the representation of visualization is manifested.Due to the developments of computer technology in recent years, various computer aided design system are invented and used in a great amount, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and collaboration, etc. (Lawson, 1995; Liu, 1996). The conventional media are greatly replaced by computer media, and the visualization is further brought into the computerized stage. The procedure of visual impact analysis and assessment (VIAA), addressed by Rahman (1992), is renewed and amended for the intervention of computer (Liu, 2000). Based on the procedures above, a great amount of applied researches are proceeded. Therefore it is evident that the computer visualization is helpful to the discussion and evaluation during the design process (Hall, 1988, 1990, 1992, 1995, 1996, 1997, 1998; Liu, 1997; Sasada, 1986, 1988, 1990, 1993, 1997, 1998). In addition to the process of architectural design, the computer visualization is also applied to the subject of construction, which is repeatedly amended and corrected by the images of computer simulation (Liu, 2000). Potier (2000) probes into the contextual research and restoration of historical architecture by the technology of computer simulation before the practical restoration is constructed. In this way he established a communicative mode among archeologists, architects via computer media.In the research of restoration and preservation of historical architecture in Taiwan, many scholars have been devoted into the studies of historical contextual criticism (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000). Clues that accompany the historical contextual criticism (such as oral information, writings, photographs, pictures, etc.) help to explore the construction and the procedure of restoration (Hung, 1995), and serve as an aid to the studies of the usage and durability of the materials in the restoration of historical architecture (Dasser, 1990; Wang, 1998). Many clues are lost, because historical architecture is often age-old (Hung, 1995). Under the circumstance, restoration of historical architecture can only be proceeded by restricted pictures, written data and oral information (Shi, 1989). Therefore, computer simulation is employed by scholars to simulate the condition of historical architecture with restricted information after restoration (Potier, 2000). Yet this is only the early stage of computer-aid restoration. The focus of the paper aims at exploring that whether visual simulation of computer can help to investigate the practice of restoration and the estimation and evaluation after restoration.By exploring the restoration of historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example), this study aims to establish a complete work on computer visualization, including the concept of restoration, the practice of restoration, and the estimation and evaluation of restoration.This research is to simulate the process of restoration by computer simulation based on visualized media (restricted pictures, restricted written data and restricted oral information) and the specialized experience of historical architects (Potier, 2000). During the process of practicing, communicates with craftsmen repeatedly with some simulated alternatives, and makes the result as the foundation of evaluating and adjusting the simulating process and outcome. In this way we address a suitable and complete process of computer visualization for historical architecture.The significance of this paper is that we are able to control every detail more exactly, and then prevent possible problems during the process of restoration of historical architecture.

summary	This paper is about the backgrounds, the present state, the results and the future expectations of the curriculum of Calibre, at the Faculty of Architecture and Building Science of the Eindhoven University of Technology. It will also touch upon the relationships with project work in our field but also in other fields of our Architectural (and Building) education. In the paper it is emphasised that teachers need to create a need for the use of certain features of computer systems. To make students aware of the (possible) CAD needs and answering to those needs at a more or less individual way asks a high level of understanding of the underlying concept and features of the CAD systems. Because of the flexibility (amongst other qualities), we, and so many others, have made a choice to use AutoCAD as 8 kind of thread that runs through our curriculum continuously and that exists out of 6 main parts. These parts vary from an introduction to Integrated Data Processing via CADD, Graphics and Data Structures and Expert Systems to System Development Methods. Half of our curriculum Is compulsory for all the faculty students, the other half is facultative but very well attended.

summary	The establishment of Datacentret (the Data Centre) in summer 1985 was preceded by 15 years slow- moving, arduous work from the early experiments in what was then the computing laboratory under the supervision of architect Per Jacobi, author of the Danish 3D drawing system MONSTER, until 1984, when a special committee was commissioned to draw up proposals for the introduction of teaching in computing at the Architects School. In spring 1985 the school administrators decided that a central computer workshop should be set up and in cooperation with the school's institutes placed jointly in charge of instructing teachers and students, carrying out research and development within the field of architecture and taking steps to work out a curriculum of supplementary training for practising architects. With the aid of a special grant, 12 PC's were successfully acquired in the 2 years that followed, as well as a screen projector and other peripherals.

doi	https://doi.org/10.52842/conf.ecaade.1989.x.c7m
summary	The paper presents an approach to the problems of architectural design aided by Artificial Intelligence techniques that can solve the difficulties related to combinatorial explosion, often encountered in the past. Three expert systems, dubbed "reasoners", capable of some elementary design work and a hypothesis for their interaction have been developed. Reasoner A has an "analogical" view of space. A notion of conflict, managed by means of fuzzy logic, has been introduced. It corresponds, in an intuitive and straightforward fashion, to the common notion of conflict or contradiction in real space as a consequence of improper overlapping of actual physical objects or of their functional pertinence. Reasoner B works on formalized models of building objects. It designs new patterns from given patterns taken as defaults. Reasoner C picks up from an archive of patterns the one which best suits a list of given goals. Design is the result of interaction between the three reasoners. Finally, the proposed schema raises questions about formal structures ("images") and about the nature of culturally-linked options ("memory") on which some preliminary considerations are made. Prototypes of the reasoners are operating at the Instituto di Edilizia of the University of Ancona, Italy.

source	New Ideas and Directions for the 1990’s [ACADIA Conference Proceedings] Gainsville (Florida - USA) 27-29 October 1989, pp. 193-208
doi	https://doi.org/10.52842/conf.acadia.1989.193
summary	The paper describes the methodology and the current efforts to develop an interdisciplinary computer aided learning system for architects and civil engineers. The system being developed incorporates a component oriented relational database with an existing interactive 3-dimensional modeling system developed in the School of Architecture and Planning at SUNY Buffalo. The software will be used in existing courses in architecture and civil engineering as a teaching aid to help students understand the complex 3-dimensional interrelationships of structural components. Initial implementation has focused on the modeling of the components and assemblies for a lowrise steel frame structure. Current implementation efforts are focusing on the capability to view connections in various ways including the ability to "explode" a connection to better understand the sequence of construction and load paths. Appropriate codes, limit states of failure and specific data will be linked to each specific component in an expert system shell so that the system can offer feedback about a student generated connection and perhaps offer other possible connections a library of standard connections. Future expansion of the system will include adding other "systems" of a building, such as mechanical, electrical, plumbing, enclosure etc., to help students visualize the integration of the various parts.

title	Compositing 3D Images with Antialiasing and Various Shading Effects
source	IEEE Computer Graphics & Applications 9 no. 2: 21-29
summary	A method is proposed for compositing 3-D images produced by different programs, taking depth order into consideration. The method can add the following effects to composited images: antialiased images with scaling are displayed by a simple algorithm; the algorithm can add shading effects due to various types of light, such as area sources and skylight; and ray tracing can be performed in localized regions, producing realistic results without the computational expense of ray tracing the whole image. In addition to the above processes, such shading effects as fog and texture mapping can be processed with conventional methods. Thus, it becomes possible to display complex scenes with various shading effects, using relatively small computers. The multiscanning method used for antialiasing and a data structure for processing it are described. Examples are presented to demonstrate the capability of the system.

title	Color Contrast and CAAD: The Seven Color Contrasts of Johannes Itten
source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 469-478
summary	Computer-aided architectural design is design with color - the monitor of a CAAD system is a display of color, a place where images are produced by color manipulation. The success of these images can be judged by the ability of the colors selected to communicate graphic ideas and to convey graphic information. Color as a visual phenomena intrigued the impressionist painters at the end of the nineteenth century; it was the focus of much attention at the Bauhaus in Weimar Germany. When Johannes Itten was appointed as a Master of Form at the Bauhaus in 1919, he developed "an aesthetic color theory originating in the experience and intuition of a painter". In his definitive work, Itten postulates seven ways to communicate visual information with color. "Each is unique in character and artistic value, in visual, expressive and symbolic effect, and together they constitute the fundamental resource of color design". These seven contrasts provide a lexicon of the methods by which computer images convey graphic information. The colors which form a computer image can be simply manipulated to illustrate these contrasts; today's computers make color manipulation a very simple matter. This paper is composed of short essays about each of these contrasts and how they can guide the selection of appropriate colors to convey visual intent on a picture tube. Considered together the contrasts of Itten provide a fundamental resource for electronic graphic communication.

source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 187-199
summary	The concept of a knowledge based design shell is proposed as a basis for teaching design. The significance of the concept of design shell is discussed with respect to formalization, implementation, application and operation. GPRS-a generative prototype refinement design shell-is proposed, defined and elaborated. A plan type is introduced as one significant kind of structure of knowledge in architectural design is introduced. A method for representing syntactic and the semantic content to be used in design refinement is proposed. The method exploits the characteristics of both rules and frames, and integrates them in a prototype-based design system. This is demonstrated in a system called PRODS. Finally, the significance of such an approach in teaching is discussed.

source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 229-238
summary	A primary aim of the Light Table project was to see if a combination of the optical laser disc, local area networks, and interactive videographic workstation technology could bring a major visual collection, (such as the Rotch Visual Collections of the Massachusetts Institute of Technology), to a campuswide population of undergraduate users. VIS (Visual Information System) is the name being given to the new genre of information technology. Much research and development effort is currently being applied to areas where the image has a special significance, for example in architecture and planning, in graphic and fine arts, in biology, in medicine, and in photography. One particular advance in the technology of VIS has been the facility to access visual information across a distributed computer system via LAN (Local Area Networks) and video delivery systems, (such as campus TV cable). This advance allows users to retrieve images from both local and remote sources, dispatching the image search through the LAN, and receiving the images back at their workstation via dedicated channels on the campus TV cable. Light Table is the title of a system that acts as a computer-based interactive videographic interface to a variety of visual information systems described in the body of this paper. It takes its name from the traditional, back- lit, translucent light table that lecturers use to assemble and view collections of slides for talks and seminars. The component of Light Table which is being reported in greatest detail here, a software outcome called Galatea, is a versatile and robust system capable of controlling video devices in a networked environment.

summary	No matter what the medium, architects are constantly using images in all aspects of design thinking. Whether it is the perception of the environment, an image in the mind's eye, an abstract drawing or a photographic record, designers use images to conceive of, and manipulate their design ideas. Managing these image collections occurs at a variety of levels in the creative process and is dependent on the type of image that is called upon for reference. The most basic example would be the image collection residing in the mind's memory which is a result of the designer’s world experiences and the relative impressiveness of each experience. Clearly, personal memory plays a significant role in the use of imagery in design, but it is unreliable and can be abstracted in uncontrollable ways. The sketchbook and later photographic collections of the grand tour were the beginnings of efforts to manage and utilize image collections as an aid to drawing and thinking about design. Now the capacity to use electronic means of creating, altering, storing, and retrieving images will enable designers to effectively use large image collections in ways that have not been possible before. This paper describes current work at the School of Architecture at Washington University in a graduate design studio. The students use a powerful 3D modeling CAD system (HOKDraw) to design and present their studio projects. In addition, we are experimenting with an image storage and retrieval system which is directly linked to the CAD model through a relational database (INGRES). Access to the database and images is instantly available through the command language and graphic display. The CAD model in effect becomes a 3D menu to an extensive image database stored on an optical memory disc recorder. Several collections are available to the studio members: the library's slide collection which relates to the studio project, specific photographs and drawings of the project site, and personal image collections stored by individuals for their own reference. The commonly accessible images are basically background material and images collected by the students to document the site, urban context and building typology. The personal images collections are any images (drawings, photographs, published images, CAD images) created or collected by the students for purposes of informing their design thinking. This work relates to the use of precedents and typology in architecture as a point of departure as well as in development of design ideas.

title	Integrating Microcomputer CADr and Bill of Material Routines Using AutoCad
source	CAAD: Education - Research and Practice [eCAADe Conference Proceedings / ISBN 87-982875-2-4] Aarhus (Denmark) 21-23 September 1989, pp. 9.2.1-9.2.10

summary	Through the integration of microcomputer-aided draughting (CADr), and in particular with AutoCAD, the industries most extensively used CADr program, and automated routines for the production of bills of materials, a dramatic incr-ease in productivity is possible in the architectural design domain. Working from a variety of material take off methods complete cost estimates may be achieved through the manipulation of drawing data and exchanging the information with third-party estimating software. However, the area of study is currently at a formative stage of development and full integration, although technically feasible, is rarely attempted. Therefore, the paper comments on the development of 'in-house' routines using AutoCAD's data extraction features and AutoLISP; reviews current commercial systems of interfacing AutoCAD with bills of materials and automated specification routines; and, finally, discusses possible future advances in this major area of study.

title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs

summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.
