title	Sharing hidden power - Communicating latency in digital models

summary	As digital spatial models take on the complex relationships inherent in a lattice of dependencies and variables, how easy is it to fully comprehend and communicate the underlying structure and logical subtext of the architectural model: the metadesign? The design of a building, the relationships between a host of different attributes and performances was ever a complex system. Now the models, the representations, are in the early stages of taking on more of that complexity and reflexivity. How do we share and communicate these modelling environments or work on them together? This paper explores the issue through examples from one particular associative geometry model constructed as research to underpin the collaborative design development of the narthex of the Passion Façade on the west transept of Gaudi’s Sagrada Família church, part of the building which is now in the early stages of construction.

title	Blurring the Lines: Computer-Aided-Design and -Manufacturing in Architecture
source	Wiley-Academy, London 224 pp. Architecture in Practice series
summary	The first few years of the 21st century have seen a revolution in the ways that we think about designing and making buildings. In no other area is this more apparent than in the interface of computer-aided design (CAD) and computer-aided manufacture (CAM). The potential blurring or assimilation of these two systems holds the still elusive but golden promise of a direct, smooth transference of design data into large-scale production facilities in which components are directly cut, modelled and moulded. How far off are we from seeing the widespread adoption of this technology? What is the potential for CAD/CAM beyond tailor-made forms? In the future, what is the possibility of complex, large-scale forms being run out in mass-customised buildings?

title	Restitution and Interpretation of Spatial Representations: A New Approach for Teaching Representation
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 840-847
doi	https://doi.org/10.52842/conf.ecaade.2006.840
summary	The use of computers has changed the practice of spatial representations. The users are no longer drawers but modelers who need to be able to check the coherence of models. The teaching of representations has to adapt with this evolution, especially in Schools of Architecture. A pedagogical way is to give interpretation tools of spatial representations through projective properties (incidence or affine properties) and consequence of intrinsic constraints (parallelism, orthogonality, and symmetry). The application of this knowledge is essential for the rebuilding of existing 3D objects or for a design process, with the restitution of 3D models from sketches. These approaches are illustrated in a pedagogical way, using dynamic geometry, in the restitution of the polyhedron of the engraving “Melencolia I” of A. Dürer, and in a dynamic sketch of a skylight inspired of the Vitra museum of F. Ghery.

title	SoundScapes & Architectural Spaces - Spatial sound research in digital architectural design
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 684-689
doi	https://doi.org/10.52842/conf.ecaade.2006.684
summary	The paper presents ongoing research focusing on the development of digital tools and methodologies for spatial design based on non-Euclidean geometries. It addresses the way sound can be used both conceptually and acoustically in the early stages of the design process, examining digital architectural design and modeling based on three-dimensional sound visualization and the acoustical analysis and evaluation of complex curved surface geometry. The paper describes SoundMatrix, the first part of a digital design tool created by using Max/Msp/Jitter, to assist in the preliminary design of building façades in small-scale urban environments, specifically studying the possibilities of curvature to decrease sound reflection between opposing street façades. Examples from a workshop with the SoundMatrix application illustrate the real-time 3D authoring and sound spatialisation processing currently implemented in the tool.

title	FlexM: Designing a physical construction kit for 3d modeling
source	International Journal of Architectural Computing vol. 4 - no. 2, 27-47
summary	We have designed a hub and strut kit that interfaces to a 3D graphics application. FlexM is a prototype flexible physical interface for manipulating and building 3D geometry. Using the FlexM hub and strut components, designers can build and explore 3D geometry with the ease of a toy and the power of a computer. The hubs transmit the model's topology and geometry to the computer, where the model is rendered on the screen in real time. The paper reports on the iterative development of several versions of the project.

title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
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.

title	Towards a Sketching Tool for Architects: 3D Reconstruction of Polyhedron
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 132-135
doi	https://doi.org/10.52842/conf.ecaade.2006.132
summary	This paper presents a tool for assisting 3D modeling from perspective projections. The proposed system uses a projective geometry engine capable of rebuilding a 3D model from a set of lines and geometric constraints. A dialogue interface assists the user in expressing geometric constraints. The system finds out the relevant geometrical components in the sketch and automatically posts the constraints. The system is limited to rebuilding polyhedrons. If we can deduce, from a perspective sketch of a polyhedron, the planar constraints of the faces and the parallelism constraints of the edges that meet in the same vanishing points, the geometric engine will be able to build a 3D model of the polyhedron.

title	Teaching parametric design in code and construction
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 158-161
summary	Automated manufacturing processes with the ability to translate digital models into physical form promise both an increase in the complexity of what can be built, and through rapid prototyping, a possibility to experiment easily with tangible examples of the evolving design. The increasing literacy of designers in computer languages, on the other hand, offers a new range of techniques through which the models themselves might be generated. This paper reviews the results of an integrated parametric modelling and digital manufacturing workshop combining participants with a background in computer programming with those with a background in fabrication. Its aim was both to encourage collaboration in a domain that overlaps both backgrounds, as well as to explore the ways in which the two working methods naturally extend the boundaries of traditional parametric design. The types of projects chosen by the students, the working methods adopted and progress made will be discussed in light of future educational possibilities, and of the future direction of parametric tools themselves. Where standard CAD constructs isolated geometric primitives, parametric models allow the user to set up a hierarchy of relationships, deferring such details as specific dimension and sometimes quantity to a later point. Usually these are captured by a geometric schema. Many such relationships in real design however, can not be defined in terms of geometry alone. Logical operations, environmental effects such as lighting and air flow, the behaviour of people and the dynamic behaviour of materials are all essential design parameters that require other methods of definition, including the algorithm. It has been our position that the skills of the programmer are necessary in the future of design. Bentley’s Generative Components software was used as the primary vehicle for the workshop design projects. Built within the familiar Microstation framework, it enables the construction of a parametric model at a range of different interfaces, from purely graphic through to entirely code based, thus allowing the manipulation of such non-geometric, algorithmic relationships as described above. Two-dimensional laser cutting was the primary fabrication method, allowing for rapid manufacturing, and in some cases iterative physical testing. The two technologies have led in the workshop to working methods that extend the geometric schema: the first, by forcing an explicit understanding of design as procedural, and the second by encouraging physical experimentation and optimisation. The resulting projects have tended to focus on responsiveness to conditions either coded or incorporated into experimental loop. Examples will be discussed. While programming languages and geometry are universal in intent, their constraints on the design process were still notable. The default data structures of computer languages (in particular the rectangular array) replace one schema limitation with another. The indexing of data in this way is conceptually hard-wired into much of our thinking both in CAD and in code. Thankfully this can be overcome with a bit of programming, but the number of projects which have required this suggests that more intuitive, or spatial methods of data access might be developed in the future.

title	Design innovation through constraint modeling
source	International Journal of Architectural Computing vol. 4 - no. 1, 87-105
summary	In this paper we describe how constraint modeling can support design innovation. Furthermore, we lay out how constraints are employed in the construction and exploration of a model's design space. We place the approach within the context of design exploration using computational and conceptual representations of design. A review of the literature reveals that geometric, topologic, functional, and quantitative constraints are those most commonly used. For each constraint type, an example is presented drawing from several workshops and research conducted by the author. The examples range from product design, to structural design, to fabrication issues in freeform geometry. Based on the case studies, we describe how the different types of constraints can be used as design drivers and help in the exploration of solution spaces. In conclusion, we identify the need for bidirectional exercising of constraints as the next challenge in design exploration and discuss how it is relevant in particular for cross domain design.

title	On Design Continuity with Smart Cloud of Points
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 794-797
doi	https://doi.org/10.52842/conf.ecaade.2006.794
summary	The continuity of the design process is not well supported by the widespread available CAD systems that mainly focus on specific design stages overlooking the transition between them, where some of the design information is lost or duplicated. The growing use of complex geometries in architectural design projects led to the adoption of constraint-based parametric modeling techniques in the construction industry. Applying these techniques and tools requires rationalizing the design solution and fixing its geometry at an early design stage. When done prematurely, it can result in design fixation and restrain the design creativity, putting it within constraints. In this paper we explore the use of Smart Cloud of Points (SmCP) as an adaptive design media supporting the continuity of the design process.

summary	Over the last 15 years, rapid prototyping has been an integral part of the design process in the car and aerospace industry (Brad Fox 2006). Recently the architecture profession has started to use these techniques in its design process (Greg Corke 2006), and some architecture schools have begun experimenting with these technologies. ¶ Foster + Partners have been one of the first architecture practices to fully integrate rapid prototyping within its design process. The technology was initially seen as a sketch model making tool in the early stages of the design, in particular for projects with complicated geometries. It surpassed this purpose within a year and it is now seen an essential design tool for many projects and in for many project stages. The office’s rapid prototyping department now produces about 3500 models a year. ¶ Besides, or perhaps because of, rapid prototyping, Foster + Partners have started to experiment with rapid manufacturing. This first was done through the design and manufacture of a Christmas tree for the charity organisation Save the Children.

title	Interactive Parametric Design and the Role of Light in Byzantine Churches
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 798-803
doi	https://doi.org/10.52842/conf.ecaade.2006.798
summary	Byzantine church design depended heavily on natural light which was used for evocative purposes. The orientation of the main axis of the church, the form of the apse and the location and size of its windows are affected by the need for sunlight to shine at the altar on a desired time and for a certain duration. Until now the process of accurately taking account of all the above parameters has been rather difficult and tedious. This paper illustrates the use of digital tools both for the analysis of the geometry of existing apse designs and the parametric generation of new ones. A sophisticated computer program was used to calculate sun angles during the Byzantine period incorporating calendar changes. In addition, Bentley System’s Generative Components software was used to construct a parametric model that allows the user to define the geometric conditions and parameters of the apse. The software would then iterate through multiple solutions to satisfy the desired conditions as well as allow the user to change the conditions at will. The tools were used to discover the geometry of the apse of the Byzantine church of Hagia Sophia in Constantinople and to analyze the apse of the Post-Byzantine church of the Xeropotamou monastery on Mount Athos in Greece. The paper concludes with a discussion of the role of parametric tools for architectural analysis and the generation of possible design solutions.

summary	Over these last hundred years since the beginning of the twentieth century, the world's population has increased from 1.6 billion to 6 billion. At the same time, people have concentrated in urban areas in ever greater numbers. As a result, society has suddenly been obliged to construct quantities of buildings rapidly and economically. In responding to this challenge, the demand has been for architecture independent of any special regional or environmental character, simple homogeneous spaces that could be factory-produced. Modernist architecture gave theoretical bases to societal demands as well as a normalized aesthetic mean. Under the ideological banner of Mies van der Rohe's dictum "Less is more," the Modernists drew up beautiful continuous spaces on a uniform grid. While Le Corbusier's assertion that "The house is a machine for living in" found concrete expression in an idealized architecture of pure geometric forms--circles, cubes, cylinders.

summary	Friedrich Schelling's famous quote, "Architecture is Frozen Music" attempted to find a relationship between the solidity of architecture and the intangibility of music in his era. While the Baroque, and subsequent Rococo, styles in architecture contain a plasticity and flow of ornament that seems to validate the statement, it does not go beyond purely surface characteristics. If we look at the purpose, goal and process of both music and architecture, finding clear relationships is difficult, though this does not deter architects from finding inspiration in music, and vice-versa.

title	Constructing the String Wall - Mapping the Material Process
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 326-335
doi	https://doi.org/10.52842/conf.ecaade.2006.326
summary	The String Wall is the emergent product of a study on technological applications in architecture. Our team attempted to test the limits of the common partition wall construction, challenging the standard notion of the partition screen wall that recedes behind the structures, spaces and objects as a background condition. Such vibrant a partition as the SW becomes the center to the formation of the space it defines. The story of the SW could be described as the organic combination of the bow and the twist. The latent materiality and geometry of the bow and the twist as composite systems that are mined for their structural, tectonic and programmatic potential are tested prior to final construction by 3D printed scaled models. The SW is composed of successive frames that consist of vertical twisted strips of plywood attached to wooden beams. These frames emulate the stud elements of the conventional dry wall partition systems and are manufactured entirely manually. On the other hand, the use of CNC milling machine is employed for the production of the bowed plywood strips that fill in the frame. Three fluctuated curvatures produce strips that are combined rhythmically to produce the striated effect of the SW. The material is manipulated in order to expose its hidden side, the sequence of the multiple layers of the different infilling conditions. The oblique perspective of the SW is achieved through a novel geometric transparency, thus offering constantly changing views to a moving observer. The manipulation of the position of the component bowed and twisted strips explore the application of a see-through condition that escapes the norm and reveals the back to the front in a unique whole. The void of the screen wall becomes ultimately programmatic through the use of light. A sequence of halogen lights situated at the top and bottom of the in-between the wooden strips void create the dumbfounded effect of the SW experience.

summary	In this paper we report on ongoing research in which the implications of urban scale pervasive computing (always and everywhere present) are investigated for urban life and urban design in the heritage environment of the city of Bath. We explore a theoretical framework for understanding and designing pervasive systems as an integral part of the urban landscape. We develop a framework based on Hillier's Space Syntax theories and Kostakos' PSP framework which encompasses the analysis of space and spatial patterns, alongside the consideration of personal, social and public interaction spaces to capture the complex relationship between pervasive systems, urban space in general and the impact of the deployment of pervasive systems on people's relationships to heritage and to each other. We describe these methodological issues in detail before giving examples from early studies of the types of result we are beginning to find.

summary	Some researchers have tried to answer the question: do we need to think differently while designing in terms of the digital environment? This methodological question leads to another question: what is the range of this difference, if there is one? This research investigates the range of changes in how architects conduct and develop the initial design within the digital environment. The role offered by the digital environment in visual design thinking during conceptual designing through shaping: concepts, forms, and design methods, is identified and explored.

title	An Analysis of the Applications of Rapid Prototyping in Architecture

summary	Rapid prototyping (RP) techniques are widely used within the design/manufacturing industry and are well established in manufacturing industry. These digital techniques offer quick and accurate prototypes with relatively low cost when we require exact likeness to a particular scale and detail. 3D modeling of buildings on CAD-systems in the AEC sector is now becoming more popular and becoming widely used practice as the higher efficiency of working with computers is being recognized. However the building of scaled physical representations is still performed manually, which generally requires a high amount of time. Complex post-modernist building forms are more faithfully and easily represented in a solid visualization form, than they could be using traditional model making methods. Using RP within the engineering community has given the users the possibility to communicate and visualize designs with greater ease with the clients and capture any error within the CAD design at an early stage of the project or product lifecycle. In this paper, the application of RP in architecture is reviewed and the possibilities of modeling architectural models are explored. A methodology of developing rapid prototypes with 3D CAD models using methods of solid freeform manufacturing in particular Fused Deposition Modeling (FDM) is presented and compared against traditional model making methods. An economical analysis is presented and discussed using a case study and the potential of applying RP techniques to architectural models is discussed.
