summary	For most architects, it is not easy to transform their freeform designs into buildable constructions without precise knowledge on a specifi c material and its construction process.A workfl ow is introduced in this paperand it could be adopted by architects concerning the works of predicting the tiling results in the earliest design stage.The workfl ow involves pre-processing which could help architects design rational surfaces, thus saving a lot of work in the paneling process later on. The physically based modeling engine will simulate the constraints of a pre-selected material and therefore ensures a feasible result. The post-process involves visual feedback of the result as well as data formatting which help to establish a seamless connection between construction processes.

title	Robotic Plaster Carving: Formalizing subtractive detailing of plaster surfaces for construction and crafts

summary	Plaster has been a fundamental material in numerous interior and exterior applications in architectural construction due to its fire-resistant properties and capabilities for intricate detailing. Moreover, prior to the widespread adoption of computer-aided design tools, plaster played a crucial role in historic preservation and architectural education (Mankouche & Schulte, 2012). While the use of decorative plaster elements in architectural construction has waned in popularity, the renewed interest in plaster within the context of advanced robotic fabrication offers a compelling basis for research. This paper presents an investigation into robotic plaster carving for adding detail and texture to plaster surfaces. Within the scope of this study, we identify and systematically examine various fabrication and material parameters for emergent geometries and fabrication defects, subsequently formalizing this robotic workflow for diverse applications in construction and crafts. Among these parameters, we primarily concentrate on toolpath geometry, tool orientation, carving speed, carving profile, and aggregation of carving strokes. Through this bottom-up approach, our objective is to enhance the understanding of tool-material interaction during the fabrication process and achieve improved control over the resulting artifact. Building on these insights, we demonstrate how the proposed robotic plaster carving workflow can be employed for subtractive surface detailing in architectural construction and digital crafts.

title	Sphere mapping: A method for a responsive surface design
doi	https://doi.org/10.52842/conf.caadria.2012.527
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 527–536
summary	The method proposed in this project addresses the parametric manipulation of a given pattern to respond directly to a pre-defined surface. Continuing the research of Kevin Rotheroe, Yale University and founder of FreeForm Design. Rotheroe has developed a series of studies in material and surface properties. By utilising a proven pattern, the proposed method sets parameters derived from the formal properties of the original pattern and produces a new pattern that is responsive to the curvature of a complex surface. The workflow developed in this research consists of a complex blending of tools in Grasshopper and Gehry Technologies Digital Project. The intent is to achieve the aesthetics and structure offered by Rotheroe’s original research and to add a responsive precision that provides an accurate adaptation of the pattern based on curvature of a specific computationally defined surface.

summary	This paper will demonstrate two effective facade rationalisation patterns developed at Gehry Technologies for mitigating the tradeoffs between project constructability constraints vs. project aesthetic constraints. The two Case-Studies will present, fi rstly a method for dealing with large amounts of component instantiations and second with the economical delivery of complex project geometry through panelling. Both projects use design technology as a strategy for the integration of specialized knowledge and trades, through an effective use of information technology. The Case Studies will present the development of the Gridshell Digital Mock-Up of the Yas Island Marina Hotel in Abu Dhabi designed by Asymptote Architects and secondly the Museo Soumaya facade system in Mexico City designed by Fernando Romero LAR. This document will report the development process for obtaining relevant construction information, essential for the assembly of the facade systems by a third-party sub-contractor in support of the facade system coordination. The report concludes on the implementations of bespoke tools in support of the coordination and geometry description tasks. The tailored tool making process extends the parametric modelling system Digital Project™ in the design support role of obtaining aesthetically pleasing decompositions of the buildings Master Design Surface MDS into feasible constructible components.

title	Application of Fuzzy Logic for Optimizing Foldable Freeform Geometries: An example of a practical application – a foldable window shade
doi	https://doi.org/10.52842/conf.ecaade.2012.1.709
source	Achten, Henri; Pavlicek, Jiri; Hulin, Jaroslav; Matejovska, Dana (eds.), Digital Physicality - Proceedings of the 30th eCAADe Conference - Volume 1 / ISBN 978-9-4912070-2-0, Czech Technical University in Prague, Faculty of Architecture (Czech Republic) 12-14 September 2012, pp. 709-717.
summary	This paper concerns the current discourse on computer-aided design tools for architectural design. There are drawbacks of purely analytic design tools which hinder a system-level, end-effect oriented ideation. For instance, most freeform quadrilateral meshes are fully constrained and therefore not capable of folding. They can only fold under special circumstances – when their geometry satisfi es the conditions of over-constrained kinematics. However, such intent of folding cannot be captured using simple modeling based on parameters and constraints. Furthermore, algorithmization of mesh kinematics using formulas is infl exible, it cannot handle topological variations, and it inhibits the interactive control of the model. In this paper, a fuzzy logic algorithm which uses a goal-oriented, human-like reasoning to control the parametric model is proposed. The algorithm applies easily observable behaviors of the geometry to adjust the selected patches until the entire shell can be folded. The algorithm relies on designer-observable characteristics of motion rather than on formulaic representations. Such approach directs the designers’ focus on the desired outcome while avoiding the drawbacks of analytic modeling of complex kinematics.

title	The Forbidden Symmetries
doi	https://doi.org/10.52842/conf.acadia.2012.391

summary	The emergence of quasi-periodic tiling theories in mathematics and material science is revealing a new class of symmetry, which had never been accessible before. Because of their astounding visual and structural properties, quasi-periodic symmetries can be ideally suited for many applications in art and architecture; providing a rich source of ideas for articulating form, pattern, surface and structure. However, since their discovery, the unique long-range order of quasi-periodic symmetries, is still posing a perplexing puzzle. As rule-based systems, the ability to algorithmically generate these complicated symmetries can be instrumental in understanding and manipulating their geometry. Recently, the discovery of quasi-periodic patterns in ancient Islamic architecture is providing a unique example of how ancient mathematics can inform our understanding of some basic theories in modern science. The recent investigation into these complex and chaotic formations is providing evidence to show that ancient designers, by using the most primitive tools (a compass and a straightedge) were able to resolve the complicated long-range principles of ten-fold quasi-periodic formations. Derived from these ancient principles, this paper presents a computational model for describing the long-range order of octagon-based quasi-periodic formations. The objective of the study is to design an algorithm for constructing large patches of octagon-based quasi-crystalline formations. The proposed algorithm is proven to be successful in producing an infinite and defect-free covering of the two-dimensional plane.

title	Design: Analogue, Digital, and Somewhere in Between
doi	https://doi.org/10.52842/conf.ecaade.2012.2.273
source	Achten, Henri; Pavlicek, Jiri; Hulin, Jaroslav; Matejovska, Dana (eds.), Digital Physicality - Proceedings of the 30th eCAADe Conference - Volume 2 / ISBN 978-9-4912070-3-7, Czech Technical University in Prague, Faculty of Architecture (Czech Republic) 12-14 September 2012, pp. 273-280
summary	The problem considered in this paper is: “In what way do we design?” This paper concentrates on the early creative stages of the design process during which the designer gradually gathers the information about the problem, applying appropriate rules, tools and media. If the tools are chosen as a starting point of consideration, designing may be analysed as manual or digital. If we chose the medium - design may be considered as physical or virtual. The main thesis of this paper is that designing proceeds somewhere in between. “Somewhere in between” means the space where manual, digital, virtual are mixing, overlapping, and transforming one into the other. As a case study the process of designing of blurred function object is presented. In this experimental design studio we paid particular attention to the design process and we searched for the answer to the following questions: how to find an idea (what tools/media are helpful), how to express, fi x and transform that idea? In the paper the examples of students’ work will be presented and discussed.

title	Three Dimensional Reconstitution of an Old Town from Historical Documents: Case of the Medina of Jijel in Algeria
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 191; 285-303
summary	The three-dimensional reconstitution of cities and urban tissues was the subject of several studies and researches. In order to obtain the acquisition of the geometry of architectural or urban sets, some studies are based on Photogrammetric or on computer vision. Others have focused on the development of tools of acquisition from a laser providing a 3D scatter plot. Some of them yet focused towards the development of CAD software. The automatic generation for morphological 3D representation based on the exploitation of the architectural knowledge basis is also an option. This type of work becomes more relevant and legitimate when it concerns old cities in state of ruin or more simply missing whose remains only prints or literary descriptions similar to our case study; the old town of Jijel that many people ignore its existence. The aim of this work is to achieve a 3D reconstitution of buildings of this town based on historical documents, mostly prints, digitized old maps and plans, as well as literary texts (tales of travelers, military records, and history books). The method developed can solve and generate possible urban volumes in the most frequent cases. The 3D model obtained, despite its geometric simplicity, can view the city from different angles and open new opportunities for research in history, architecture and town planning.

title	Numerical Simulation of Effect of Urban Geometry Layouts on Wind and Natural Ventilation Under Mediterranean Climate
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 195-202
summary	The use of the method "simulation" of the microclimate for an urban site presents much of interest; because this can serve as us observation and analysis of the consequences of various scenarios relating to the existence and the importance of the constituent elements in urban space. Wind in outdoor urban space is among the most difficult parameters to identify and control field given its instability. Currently, in the field of the ventilation, there are some outdoor spaces simulation tools, used to assess the flow of the wind at different spatial scales. The aim of this research is to demonstrate the effect of the urban geometry of the layout on the wind movement and the outdoor natural ventilation. However, this study investigated the effect on outdoor thermal comfort of a building layouts in a planned residential area situated in the city of Jijel humid Mediterranean region of Algeria. In order to improve outside comfort in this open space, a 3D numerical simulation tool ENVI-met 3.1 beta 4 was used to simulate the urban thermal climate taking into account various scenarios. Thus, simulation’s results are discussed in this paper

source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 223–232
summary	The present paper tries to explore the potential of visual-heavy tools in the creation of virtual reality worlds, with an emphasis on tools borrowed from 3d electronic games. Compared to earlier approaches in virtual reality creation the paper focuses on game design tools and provides a basic framework for interaction in virtual reality, based on classic rather than digital representations, which is then expanded using digital representations. In the second part of the paper a game creation tool is assessed based on its potential not only of usability but also on guiding the designer in specific paths to designing virtual worlds. The assessment is based on a case study of interaction design.

title	Toward a performance-oriented architecture: An integrated design approach to a real time responsive structure
doi	https://doi.org/10.52842/conf.caadria.2012.059
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 59–68
summary	This paper started from the study of “performance-oriented architecture” for the purpose of developing a real time responsive prototype that can enclose large expansive interior space. Questions regarding the relationship between the structural arrangement of systems and the natural environment initiated an investigation in Phyllotaxis. It has been found in plant systems for the optimisation of photosynthesis with harvesting maximum amounts of solar energy. In the design of a real time responsive prototype, an algorithmic approach is introduced with the mathematical interpretation of Phyllotaxis and its translation into the global geometry of the prototype. Also, the usage of a Voronoi diagram is parametrically configured to form the local geometry of the prototype. The interactive mechanism of the prototype was achieved with an assorted computational application. Furthermore, with the demonstration of the aforementioned prototype in both digital and physical environments, its implementation process is explained.

summary	The walkability of open spaces has been highlighted in current discussions about the production of designed environments in urban contexts (Matan, 2011). To contribute to this theme, this work selects the environmental comfort of open spaces as its element of study. The production of urban space was investigated, specifically in regard to urban morphology, understanding that city design directly influences environmental comfort (Jacobs, 1996). This work addresses the geographic context of low latitudes, specifically in hot and humid climate zones of Brazil, and, in this context, according to NBR 15220 (national performance standards), shading is one of the main comfort strategies, so solar incidence was the approached environmental phenomenon. Thus, this work presents a digital system that performs exploratory analysis on the correlations between urban form indicators and environmental performance indicators, specifically solar incidence. The method consists of three steps: urban form modeling (1), indicator measurement (2) and correlation analysis (3). In the first stage, different spatial sections of a city in Brazil were represented in the digital environment (1). This work’s implementation instrument is based on a City Information Modeling framework (Beirao et al., 2012). Visual Programming Interface (VPI) and Geographic Information Systems (GIS) tools were used, in addition to a Relational Database Management System (RDBMS). Then, for each urban clipping, the values of morphological indicators and the incidence of solar radiation were measured (2). Based on the values of the indicators, an exploration of their correlation was carried out by statistical methods (3). The results of the correlation analysis and their correspondent scatter plots are presented. Finally, possible applications of the results for the creation of prescriptive urban planning systems are discussed, seeking to promote a sustainable urban environment.

summary	Evolution and innovation in architecture are intensely related to the rise and developments of technology. Within this context, it is possible to recognize how in recent decades this milieu has fostered the development of new methodologies for urban design and architectural practice, as is, for example, the Parameterization. This paper is focused on the subject of Parametric Urbanism: discussing / questioning the emergence of this new architectural methodology; addressing the factors that contributed to its appearance; and seeking to understand whether the parametric approach has benefits and whether it may or may not be a solution or of assistance to urban planning. The paper provides a brief literature review focused on parametric urbanism and then it presents a practical case study of parametric urbanism: an Urban Plan in Beijing, developed in an academic context, at the University École Polytechnique Fédérale de Lausanne in 2012. Having as base diverse examples of parametric urbanism, it is tried to identify/justify decisions defining principles and application guidance for this project. The conclusion presents the final considerations based on opposing the case study with the theoretical approach, seeking to clarify whether this new kind of urban design methodology, Parametric Urbanism, is or not viable.

summary	This paper examines the existing training gaps between the traditional teaching process of the Architectural Design Studio (ADS) and the new contemporary training scenarios through the perception of the ePortfolio’s use, which allows it to visualize guidelines for updating its teaching and learning process. The study is qualitative with an applied approach, based on a perception survey answered by students who attended the P2 workshop, between 2012 – 2018, in the Architecture Career of Concepción University, Chile. The results show the existence of training gaps associated with factors of conception, planning and development of pedagogical strategies of the training process. The conclusions allow us to observe opportunities for updating the teaching process of the ADS through the mediation of technological tools, which help to build a new pedagogical conception, more adjusted to the current and future scenarios of modernity.

title	Information Technology Utilization in Architectural Engineering: A Field Investigation at the Department of Architecture and Construction, Constantine (Algeria)

summary	This paper is derived from an under developed research work, that is a PhD thesis which studies the influence of Information Technology (IT) on architectural practice in Algeria. It examines the use of IT by students of the Department of Architecture and Construction in Constantine in their design studio’s projects. The target of the study is to inspect the depth of utilization of IT, identify the advantages and shortcomings of use, and propose some solutions. A field survey was undertaken on a sample of students at the Department of Architecture and Construction. The survey has the following objectives: • to find out the students’ motivation behind the adoption and use of IT in their projects; • to identify the negative and positive aspects of use; • to identify the barriers that would hinder better use; and • to determine the impact of the IT tools on the design process and projects. // For a more comprehensive comprehension of the study case; a pilot field survey was conducted during two consecutive years. This enables the researchers to make comparisons between the survey’s results of the same year, and to study the trends of use by making comparisons between the results of these two years. SPSS was used to analyze the results. The analysis of results shows that the IT helps largely to improve the quality of presentations of the documents, images and graphics but this was an attempt from students to satisfy and influence the "others". In some cases, this has negatively affected the quality of design projects. It was used by students with poor design skills to cover up some weak aspects and faults in their design projects. On the other hand, some tutors opposed the exaggerated use of IT and the complete dependence on the computer during the design stage. They prefer the "traditional way" of design development. There is an ongoing conflict and arguments between students and tutors regarding this matter. However, It was noticed that the IT has effectively contribute in improving the competition level between students thus the quality of their design projects.

title	The Role of Social Interaction in Empowering the Innovative Utilization of CAAD
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 253-262
summary	The production of Innovative projects is the ultimate goal of architects and the previous research highlighted that certain negotiation, collaboration and communications activities are essential to initiate creativity and produce innovative design products. CAAD systems help the architect in formulating and developing design ideas. Research studies have concentrated on the usability and shortages of these systems, the users' attitude, knowledge and their acceptance of these systems. However, few studies have investigated the relation between the social settings of a design studio and the utilization of CAAD systems. This research explores the link between the social settings and the utilization of CAAD in producing innovative design products. It argues that certain design studio's settings would affect the use of CAAD systems in an innovative way. In 2012, students at college of Architecture, University of Dammam were surveyed to find out how the design studio's settings would support/ hinder the utilization of CAAD systems. The survey results showed that innovative students, who undertake certain design and communication tasks, found that CAAD systems are more useful in producing innovative projects. The study makes recommendations on how to set healthy social interaction conditions in the design studio and initiate innovative behaviour while using CAAD systems during the design process.

title	Edible Infrastructures: Emergent Organizational Patterns for the Productive City
doi	https://doi.org/10.52842/conf.acadia.2012.511
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 511-526
summary	Edible Infrastructures is an investigation into a projective mode of urbanism which considers food as an integral part of a city's metabolic infrastructure. Working with algorithms as design tools, we explore the generative potential of such a system to create an urban ecology that: provides for its residents via local, multi-scalar, distributed food production, reconnects urbanites with their food sources, and de-couples food costs from fossil fuels by limiting transportation at all levels, from source to table. The research is conducted through the building up of a sequence of algorithms, beginning with the ‘Settlement Simulation’, which couples consumers to productive surface area within a cellular automata type computational model. Topological analysis informs generative operations, as each stage builds on the output of the last. In this way we explore the hierarchical components for a new Productive City, including: the structure and programming of the urban circulatory network, an emergent urban morphology based around productive urban blocks, and opportunities for new architectural typologies. The resulting prototypical Productive City questions the underlying mechanisms that shape modern urban space and demonstrates the architectural potential of mathematical modeling and simulation in addressing complex urban spatial and programmatic challenges.

summary	Design is a goal oriented decision-making activity. Design is ill defined and requiring of synthetic approaches to weighing and understanding tradeoffs amongst soft and hard objectives, and the imprecise and or computationally explicit criteria and goals. In this regard designers in contemporary practice face a crisis of sorts. How do we achieve performance under large degrees of uncertainty and limited design cycle time? How do we better design for integrating performance? Fundamentally design teams, are not typically given enough time nor the best tools to design explore, to generate design alternatives, and then evolve solution quality to search for best fit through expansive design solution spaces. Given the complex criteria for defining performance in architecture our research approach experiments upon an evolutionary and integrative computational strategy to expand the solution space of a design problem as well as pre-sort and qualify candidate designs. We present technology and methodology that supports rapid development of design problem solution spaces in which three design domains objectives have multi-directional impact on each other. The research describes the use of an evolutionary approach in which a genetic algorithm is used as a means to automate the design alternative population as well as to facilitate multidisciplinary design domain optimization. The paper provides a technical description of the prototype design, one that integrates associative parametric modeling with an energy use intensity evaluation and with a financial pro forma. The initial results of the research are presented and analyzed including impacts on design process; the impacts on design uncertainty and design cycle latency; and the affordances for ‘designing-in’ performance and managing project complexity. A summary discussion is developed which describes a future cloud implementation and the future extensions into other domains, scales, tectonic and system detail.

title	Rationalisation of freeform façades: A technique for uniform hexagonal panelling
doi	https://doi.org/10.52842/conf.caadria.2012.243
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 243–252
summary	This paper is an account of the façade rationalisation strategy developed at Gehry Technologies for mitigating the tradeoffs between project constructability and the aesthetic implications of arranging flat panels over a complex surface. The strategy outlined was developed as the result of the digital building delivery of the Museo Soumaya façade in Mexico City designed by Fernando Romero LAR. This report documents the development process of a method for obtaining relevant construction information flows enabling the assembly of the façade system by a third-party sub-contractor in support of the façade system coordination. This report concludes on a method using bespoke software for extending the parametric modelling system Digital Project™ in the design support role of obtaining an aesthetically pleasing arrangement of flat hexagonal panels over a freeform surface.

title	3d Virtuality Sketching: Interactive 3d Sketching Based on Real Models in a Virtual Scene
doi	https://doi.org/10.52842/conf.acadia.2012.409
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 409-418
summary	Sketches and working models are without doubt one of the most widely used tools in the architect’s repertoire. In the early phases of the design process in particular, they represent an essential part of the exploration process. For the most part, however, sketching and model building are separate and sequential steps. This paper examines how both media can be linked to each other more effectively so that the design process is more continuous and the transition between the two media more fluid. Using a multi-touch table with additional 3D real-time object recognition, a prototypical system was developed and realised as part of a research project in which an interactive 3D sketching tool was linked with a real 3D working model.
