title Ivy: Bringing a Weighted-Mesh Representations to Bear on Generative Architectural Design Applications
source ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 140-151

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

summary A review of the literature on Intelligent Buildings suggests an ideal of a building as an autonomous system that controls its internal and external environments. The model, whose origin lies with early models of artificial intelligence, effectively treats the building as a slave to human needs, and appears to invest more intelligence in the building than in its occupants. This paper proposes that automated environments be understood as extensions of human sense and awareness. It describes an operating system, Arch-OS, that exemplifies this approach by increasing building occupants’ consciousness of their environment.

summary This paper presents a study in digital design and manufacturing of shells, which are material-efficient systems that generate their load-bearing capacity through curvature. Their complex shapes are chal­lenging to build, and the few current shell projects employ the same shape repetitively in order to reduce the cost of concrete formwork. Can digital design and manufacturing technology make these systems suitable for the needs of the 21st century? The research developed new digitally-driven fabrication processes for Wood-Foam Sandwich Shells and Ferrocement-Concrete Sandwich Shells. These are partially pre-fabricated in order to allow for the application of Computer-Numerically Controlled (CNC) technology. Sandwich systems offer advantages for the digitally-enabled construction of shells, while at the same time improving their structural and thermal performance. The research defines design and manufacturing processes that reduce the need for repetition in order to save costs. Wood-Foam Sandwich shells are made by laminating wood-strips over a CNC-milled foam mold that eventually becomes the structural sandwich core. For Ferrocement-Concrete sandwich shells, a two-stage process is presented: pre-fabricated ferrocement panels become the permanent formwork for a cast-in-place concrete shell. The design and engineering process is facilitated through the use of parametric solid modeling envi­ronments. Modeling macros and integrated Finite-Element Analysis tools streamline the design process. Accuracy in fabrication is maintained by using CNC techniques for the majority of the shaping processes. The digital design and manufacturing parameters for each process are verified through design and fabrication studies that include prototypes, mockups and physical scale models.

summary We are presenting design ideas, technical innovation, and fabrication expertise that address crucial issues. Authors investigate how to effectively design and practice architecture with automated prototyping and manufacturing. We want to understand where this might lead, and how it might change the nature of architecture itself. We are just beginning to discover the opportunities to be found in integrating automated fabrication within the practice of architecture. At the same time, the new century has brought very mixed perspectives on confident Modern progress. A cautious scrutiny of 'innovation' is needed. Fabrication is an old word with the straightforward meaning, to make. The roots of the word lead to the origins of architecture. Making has been considered a virtue by ancient writers and modern politicians alike. Fabrication (and homo faber, 'one who makes') have served as fundamental terms that constitutions and contract laws have been built upon. Shaping and working with materials is at the core of Western civilization. However at a point in human history where nature is steadily being replaced by human artifice, the consequences of making are far from simple. Whether for good or ill, our new fabricated environment is transforming the world.

summary The computer in architectural design has shifted from its role as a merely representational device to that of a tool for instrumentalized simulation and fabrication. The desire to make buildings look like a rendering, or to produce photo-realistic images and walkthroughs has given way to an opening of the potentials of software to assist the designer with managing complex geometries, parametric organizational diagrams, structural analysis, and integrated building systems. Simulation has become the means by which virtual space becomes more than just a mirror of reality. It becomes the space within which different potential realities can be tested and evaluated before they are materially implemented. In architecture, information derived from material constraints to site conditions can be constantly fed into the computer models to provide an accurate update, which in turn introduces feedback into the overall design, and change can then be registered in the detail.

summary The direct and rapid connections between scripting, modeling and prototyping allow for investigations of computation in fabrication. The manipulation of planar materials with two-dimensional CNC cuts can easily create complex and varied forms, volumes, and surfaces. However, the bulk of research on folding using CNC fabrication tools is focused upon surfaces, self-supporting walls and shell structures, which do not integrate well into more conventional building construction models.This paper attempts to explain the potential for using folding methodologies to develop structural members through a design-build process. Conventional building practice consists of the assembly of off-the-shelf parts. Many times, the plinth, skeleton, and skin are independently designed and fabricated, integrating multiple industries. Using this method of construction as an operative status quo, this investigation focused on a single structural component: the truss. A truss is defined as: “A triangulated arrangement of structural members that reduces nonaxial external forces to a set of axial forces in its members.” (Allen and Iano 2004)Using folding methodologies and sheet steel to create a truss, this design investigation employed a recyclable and prolific building material to redefine the fabrication of a conventional structural member. The potential for using digital design and two-dimensional CNC fabrication tools in the design of a foldable truss from sheet steel is viable in the creation of a flat-packed, minimal waste structural member that can adapt to a variety of aesthetic and structural conditions. Applying new methods to a component of the conventional ‘kit of parts’ allowed for a novel investigation that recombines zero waste goals, flat-packing potential, structural expression and computational processes.

summary Argenìa is a Generative System activating a process that is analogous to a genetic code and that forms the basis of artificial worlds. It is a design activity, whose aim is not only to obtain a single result. It is an executable code that is capable of producing infinite variations during its evolutionary process. This is an inspiring experience. We can reread the meta-design approach of the sixties as a concrete realization of three-dimensional models, belonging to a species.

summary Along with the development of computer technologies and CAD/CAM, digital tools are increasingly adapted in architectural design. Developed thus far, functions of digital tools are no long limited to two-dimensional drafting or final presentation; they have become tools that can assist design thinking. Because of the involvement of digital tools, the design process has been greatly affected; or, one may say that digital tools liberated the confines of forms and structuring of architectures. This research aims to explore the procedures in the design process using digital tools. In the conclusion, we found that in an attempt to abridge the gap between design ideas and actual implementation, the designer used the digital reality simulation function very frequently to assist in decision making, and in order to process more complex and freer forms, the designer relied on the 3D design environment to carry out his thinking process and amendments. In addition, the digital design process is mainly conducted through the methods of 1, 3D modeling, 2, Simulation, 3, Generation, and 4, Fabrication. The steps and methods in the digital design process are obviously different from the traditional ones, which focus mainly on mass-production of 2D drawings; therefore, it is certain that the new tools will change the outcome of the designs.

summary This paper presents an account of our research and development of processes providing seamless transition from design to fabrication. The narrative of our design, development, and prototyping experi¬ments spans seven years, including our current project, the Trusset software/structural system. Trusset is a combined building system and agent-based software design tool. The building system is based on a differential space-truss designed for fabrication entirely with computer numerically controlled (CNC) linear cutting devices, such as laser cut¬ters or three-axis mills. The software component is a set of agent-based design tools for developing surfaces and envelopes formally suitable to be built using the space-truss structure. Developed in parallel, the soft¬ware and building components combine within the Trusset system to provide a seamless pipeline from design to fabrication and assembly. The story of the development of software components and structural system, leading to the Trusset, act as a means of discussing the larger issues framing the research: the potential pitfalls and benefits of design and fabrication integration via the computer.

summary This paper explains the development of a digital fabrication graduate seminar that has evolved over four semesters. The class attempts to teach at various levels between ‘how to’ considerations of learning hardware and software, while exploring a deeper understanding of the technological implications on design and digital fabrication. At the heart of the course is the belief that the limitations of hardware, software, and materials can be viewed as opportunities during the making of any artifact. A number of teaching models have been employed over the four semesters that include short, abstract, directed mini-projects, which teach one skill to the opposite extreme that develops longer, open-ended research / design projects focused on a technology or technique. The products of the class are used to compare the benefits and deficiencies of various pedagogies. The work is also used to further define the desires of the course related to strategies for materials and making.

keywords The paper discusses co-design, development, production, application of TreeHugger (see Figure 1). The co-design among community and trans-disciplinary participants with different expertise required scope of media mix, switching between analogue, digital and back again. This involves different degrees of physical and digital 'GIGA-Mapping' (Sevaldson, 2011, 2015), 'Grasshopper3d' (Davidson, 2017) scripting and mix of digital and analogue fabrication to address the real life world. The critical participation of this 'Time-Based Design' (Sevaldson, 2004, 2005) process is the interaction of the prototype with eco-systemic agency of the adjacent environment - the eco-systemic performance. The TreeHugger is a responsive solid wood insect hotel, generating habitats and edible landscaping (Creasy, 2004) on bio-tope in city centre of Prague. To extend the impact, the code was uploaded for communities to download, local-specifically edit and apply worldwide. Thus, the fusion of discussed processes is multi-scaled and multi-layered, utilised in emerging design field: Systemic Approach to Architectural Performance.

doi https://doi.org/10.52842/conf.ecaade.2004.174
summary This paper describes a studio experiment developed with the aim of exploring the design and fabrication of complex architectural forms using ceramic elements. History has examples of double-sided curved forms built in ceramics. Such examples would not fulfill contemporary functional and aesthetic principles, neither would they be feasible or cost-effective considering current construction standards. There are recent examples of such forms built in other materials. These examples are difficult to emulate when ceramics is concerned, as they imply the fabrication of unique parts and sophisticated assembly techniques. Creating a double-curved surface in ceramics thus seems a difficult task. There are, however, advantages to such a formulation of design problems. They prompt the questioning of traditional wisdom, the rejection of accepted types, and the raising of interesting questions. What are the design strategies that should be followed when creating ceramic free-forms? What is the design media required to design them? And what are the techniques needed to fabricate and construct them? These are the questions investigated in the design project pursued jointly by students at an American and a Portuguese school, in collaboration with a professional research center and a ceramics factory. The students tested various possibilities, and in the process learned about state-of-art design and production techniques. The final projects are very expressive of their investigations and include a twisted glass tunnel, large-scale ceramic ‘bubbles,’ a rotated-tile wall, and a load-bearing wall system.

summary Three conditions exist that are likely to lead to significant restructuringof the construction industry. These are (1): the recognition that traditional contracting practices are inefficient and costly to the client, (2) the growing availability of information-rich 3D parametric modeling, and (3) the strong interest in integrating the issues of design and fabrication. Some aspects of these conditions are examined using two examples: parametric design and integration in steel structural design, and in fabrication-level modeling of precast concrete. The implications of these changes are explored.

summary Keyframing, Morphing, Inverse Kinematics; they are all animation technics which have been explored by diverse groups of architects, academics and students, searching for new horizons in the proyecting process development, pushing forward the present limits of proyecting methodology. We define this project starting by the explorative use of animation tools as experimental variables in reformulating our design processes. Data input have been traditionally carried out using classic interfaces such as keyboard, mouse, graphics tablet, among others. Despite this is accepted by many as the standard way of communicating with machines, we think this is still very far from the ideal way to design and model new proposals. In this context we propose to investigate a new way to approach to the computed aided modelling process, questioning and reformulating traditional interfaces in user .machine communication.

title An Energy Centric Approach to Architecture: Abstracting the material to co-rationalize design and performance

doi https://doi.org/10.52842/conf.acadia.2008.072
summary This paper begins by exploring matter as an aggregated system of energy transactions and modulations. With this in mind, it examines the notion of energy driven form finding as a design methodology that can simultaneously negotiate physical, environmental and fabrication considerations. The digital workspace enables this notion of form finding to re-establish itself in the world of architecture through a range of analytic tools that algorithmically encode real world physics. Simulating the spatial and energetic characteristics of reality enables virtual “form generation models that recognize the laws of physics and are able to create ‘minimum’ surfaces for compression, bending [and] tension” (Cook 2004). The language of energy, common in engineering and materials science, enables a renewed trans-disciplinary dialogue that addresses significant historic disjunctions such as the professional divide between architects and engineers. Design becomes a science of exploring abstracted energy states to discover a suitable resonance with which to tune the built environment. ¶ A case study of one particular method of energy driven form finding is presented. Bi-directional Evolutionary Structural Optimization (BESO) is a generative engineering technique developed at RMIT University. It appropriates natural growth strategies to determine optimum forms that respond to structural criteria by reorganizing their topology. This dynamic topology response enables structural optimization to become an integrated component of design exploration. A sequence of investigations illustrates the flexibility and trans-disciplinary benefits of this approach. Using BESO as a tool for design rather than purely for structural optimization fuses the creative approach of the architect with the pragmatic approach of the engineer, enabling outcomes that neither profession could develop in isolation. The BESO case study alludes to future design processes that will facilitate a coherent unfolding of design logic comparable to morphogenesis.

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.
