summary	The paper describes the implementation of “immersive simulation studios” at Ball State University and their impact on architectural design education. This implementation is part of our on-going research efforts aimed to expand conventionally available digital design tools by including state-of-the-art virtual reality (VR) technology in design studios. Two consecutive immersive simulation studios were held during the academic year 2013-2014; we tested teaching/learning methodologies for effectively using the VR simulation to support the students in the design of architectural spaces. The results make reference to the learning outcomes from these implementations and the level of satisfaction of students using the tool.

title	Progeny: A Grasshopper Plug-in that Augments Cellular Automata Algorithms for 3D Form Explorations

summary	Cellular automata (CA) is a well-known computation method introduced by John von Neumann and Stanislaw Ulam in the 1940s. Since then, it has been studied in various fields such as computer science, biology, physics, chemistry, and art. The Classic CA algorithm is a calculation of a grid of cells' binary states based on neighboring cells and a set of rules. With the variation of these parameters, the CA algorithm has evolved into alternative versions such as 3D CA, Multiple neighborhood CA, Multiple rules CA, and Stochastic CA (Url-1). As a rule-based generative algorithm, CA has been used as a bottom-up design approach in the architectural design process in the search for form (Frazer,1995; Dinçer et al., 2014), in simulating the displacement of individuals in space, and in revealing complex relations at the urban scale (Güzelci, 2013). There are implementations of CA tools in 3D design software for designers as additional scripts or plug-ins. However, these often have limited ability to create customized CA algorithms by the designer. This study aims to create a customizable framework for 3D CA algorithms to be used in 3D form explorations by designers. Grasshopper3D, which is a visual scripting environment in Rhinoceros 3D, is used to implement the framework. The main difference between this work and the current Grasshopper3D plug-ins for CA simulation is the customizability and the real-time control of the framework. The parameters that allow the CA algorithm to be customized are; the initial state of the 3D grid, neighborhood conditions, cell states and rules. CA algorithms are created for each customizable parameter using the framework. Those algorithms are evaluated based on the ability to generate form. A voxel-based approach is used to generate geometry from the points created by the 3D cellular automata. In future, forms generated using this framework can be used as a form generating tool for digital environments.

title	Integrated Generative Technique for Interactive Design of Brickworks
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. 49-64
summary	Bricks have been used in the construction industry as a building medium for millennia. Distinct patterns of bricks depict the unique aesthetic intentions found in Roman, Gothic and Islamic architecture. In contemporary practice, the use of digital tools in design has enabled methodologies for creating new forms in architecture. CAD and BIM systems provide new opportunities for designers to create parametric objects for building form generation. In masonry design, there exists an inherent contradiction between traditional patterns in brick design, which are formal and prescribed, and the potential for new patterns generated using design scripting. In addition, current tools do not provide interactive techniques for the design of brickwork patterns that can manage constant changes parametrically, to inform and influence design process, by providing design feedback on the constructive and structural aspects of the proposed brick pattern and geometry. This research looks into the parametric techniques that can be applied to create different kinds of patterns on brick walls. It discusses a methodology for an interactive brickwork design within generative techniques. By integrating data between two computational platforms – the first based on image analysis and the second on parametric modeling, we demonstrate a methodology and application that can generate interactive arbitrary patterns and map it to the brick wall in real-time.

title	Processo iterativo de design paramétrico e projeto estrutural aplicado ao desenvolvimento de torre eólica [Iterative process of parametric design and structural project applied to the development of lattice and wind power]
source	SIGraDi 2014 [Proceedings of the 18th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-9974-99-655-7] Uruguay - Montevideo 12 - 14 November 2014, pp. 35-38
summary	This article proposes to study the process of parametric design integrated analysis and structural design. This application model is called Performative Model; the form is generated based on performance criteria. The digital tools facilitate the information flow between designers using parametric model and Finite Element Analysis. To research the method of Performative Model is proposed the development of a conceptual framework of lattice wind tower with the aim of a quantitative and qualitative structure optimization. Therefore, the parametric modeling will be done using Rhinoceros software, the plugin for creating algorithms Grasshoper and structural analysis plugin Scan & Solve.

summary	This paper explores the application of cellular automata as method for investigating the dynamic parameters and interrelationships that constitute the urban space. With increasing aspects needed for integration during the architectural and urban design process with the relations between these aspects growing in parallel, complexity of the design process and design solution increases. Additionally, aspects and relations are of a transformative character in that they change over time and therefore construct a time-based condition for which problems are presented and solutions are sought. An architectural methodological response to this situation is presented through the development of a conceptual computational design system that allows these dynamics to unfold and to be observed for architectural design decision taking. Reflecting on the development and implementation of a cellular automata based design approach on a master level urban design studio this paper will discuss the strategies for dealing with complexity at an urban scale as well as the pedagogical considerations behind applying computational tools and methods to a urban design education.

summary	This paper presents a computational design methodology through describing of a case study on stone building system. In addition to establishing a performance driven form-finding methodology, the objective is to redefine local craftsmanship methods as industrial fabrication techniques in order to introduce the constructability of the design solutions as one of the main performance criteria. Therefore, the focus of the methodology is to facilitate architectural design processes through developing of customized computational design tools and workflows for data integration and concurrent performance evaluation. The research starts with the hypothesis that the technological advancements in digital design and fabrication can lead to re-exploration and improvement of traditional building techniques with local materials. The paper explains different stages of the methodology and the way the chained design to fabrication processes would lead to constructible, structurally possible and optimal design solutions of small scale and simple symmetric design solutions to complex topologies at the scale of larger complex buildings.

summary	By elaborating on the significance of the drawing in the architectural avantgarde of the 1960s, the paper’s primary scope is to weave a thread between late modernism and contemporary research in computational design. The architectural drawing is presented as an abstract means aiding design research. The more recent notion of performative drawing evokes adaptability, being a critical precondition that responds to diverse design aims in interactive manners. Performative drawing's function may further be linked to patterns, a recurring research theme during late modernism. Thinking in (and with) patterns recalls approaching design problems through malleable schemas that hold design data, according to which they are being transformed. In respect, the present paper delves into the analogies between the manipulation of patterns with the use of drawings during late modernism and parametric processes developed through simulation patterns of the current era. Through this comparison, it becomes possible to stress out the operative significance of methodologies and conceptual means in the architectural making as tools that are being used primarily for the exploration of form’s dynamic behaviour.

title	New Approaches to Representation in Conceptual Design
source	International Journal of Architectural Computing vol. 12 - no. 4, 359-378
summary	Design has been a human activity as long as humans are humans. In the last decades, a lot of academic research has been devoted to understand the theoretical and scientific bases on which this activity rests, and some of these aspects are beginning to be clear, in particular with respect to cognitive processes and representational needs.Therefore, in this article, we will: 1) briefly describe some current approaches to design thinking and in particular describe conceptual design; 2) analyze how current state-of-the-art software is neither designed to give an answer to these processes, nor to support conceptual design; and 3) introduce a new approach in the design of CAD software data models, so that conceptual design is better supported to truly “aid” designers in his praxis.

summary	We present a pilot study aiming to explore the use of biometrics sensing technology within a semi-immersive VR environment, where users face architectural spaces which induce them sensations close to fear of heights, claustrophobia, frustration and relief. Electrodermal activity was used to detect users’ emotional arousal, while navigating in VR. Navigation conditions and participants’ expertise with games were controlled. Main results show that physiological measurement of user’s perceptions can discriminate well "positive" from "negative" spaces, providing designers with basic information on people’s emotional state when using the buildings they design.

summary	In recent years, Building Information Models have become commonplace in building profession. The extensive use and increasing experience with BIM models offers new perspectives and potentials for design and planning. A recent stakeholder study conducted by the authors of this paper show that in practice models are no longer solely observed as culmination of knowledge in a 3d representation of future built structures, but as a source of information in itself. Experienced users of BIM want to Find Information within a model or across a set of these and Compare models in order to evaluate states of a model, differences in separate models or models from different point of time. Current BIM tools support both modes only in a rudimentary form. This paper discusses current modes of information query within and across BIM models, shows beneficial scenarios for building and planning practice through customised queries and exemplifies these on the base of a scripted tool. This customized approach is used to test approaches for a machine-based assessment of Level of detail and BIM-readiness in BIM models.

title	Adaptive [skins]: Adaptation through smart systems
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. 275-289
summary	The project investigates responsive building skin systems that adapt to the dynamic environmental conditions to regulate internal conditions in a habitable space over different periods of time by exhibiting a state of motion and dynamism. Passive and active building skins are developed using shape memory alloys and pneumatic actuators through investigations of smart systems that integrate smart materials and smart geometries. Nitinol springs are integrated in tensegrity systems to actuate the adaptive behaviour, which forms the passive roof system. Owing to the complexity of the multi-parametric system, genetic algorithms are developed for system optimization and calibrated with physical prototypes at varied scales. The developed systems are tested against two distinct climatic models- New Delhi and Barcelona, and evaluated for performance, based on heat and light, which are quantified as solar gain and illuminance as principles, and daylight factor for evaluation purpose. New tool-sets are developed in the process by combining various digital tools, to create a real-time feedback and memory loop system.

title	Machine learning in the discipline of architecture: A review on the research trends between 2014 and 2020
source	International Journal of Architectural Computing 2023, Vol. 21 - no. 1, pp. 23–41
summary	Abstract Through the recent technological developments within the fourth industrial revolution, artificial intelligence (AI) studies have had a huge impact on various disciplines such as social sciences, information communication technologies (ICTs), architecture, engineering, and construction (AEC). Regarding decision-making and forecasting systems in particular, AI and machine learning (ML) technologies have provided an opportunity to improve the mutual relationships between machines and humans. When the connection between ML and architecture is considered, it is possible to claim that there is no parallel acceleration as in other disciplines. In this study, and considering the latest breakthroughs, we focus on revealing what ML and architecture have in common. Our focal point is to reveal common points by classifying and analyzing current literature through describing the potential of ML in architecture. Studies conducted using ML techniques and subsets of AI technologies were used in this paper, and the resulting data were interpreted using the bibliometric analysis method. In order to discuss the state-of-the-art research articles which have been published between 2014 and 2020, main subjects, subsets, and keywords were refined through the search engines. The statistical figures were demonstrated as huge datasets, and the results were clearly delineated through Sankey diagrams. Thanks to bibliometric analyses of the current literature of WOS (Web of Science), CUMINCAD (Cumulative Index about publications in Computer Aided Architectural Design supported by the sibling associations ACADIA, CAADRIA, eCAADe, SIGraDi, ASCAAD, and CAAD futures), predictable data have been presented allowing recommendations for possible future studies for researchers.

summary	Layout design has been supported by some computational tools, where fuzzy systems have been approved as an appropriate method to handle uncertainty in the early design stage. In this paper, a new mathematical model depending on the fuzzy logic and sets theory is proposed to assist in layout design. The model distinctly deals with spatial uncertainty in open planned designs, where there is no clear layout configuration or definite patterns of usage. The model calculates the possibility of occupancy according to space, function and user related parameters and logical rules. It also visualises the architectural plan as being comprised of sub-spaces formed by the distribution of those possibilities. Sub-spaces are characterised as “Fuzzy Architectural Spatial Objects” (FASOs). As a result, layouts are represented as an accumulation of FASOs showing a certain inhabitation pattern. Various layouts can be generated within the identity of FASOs. Architects can evaluate the layouts and propose new ones by organising the FASOs on the plan and considering their relations. After describing the model the paper demonstrates an application which aims to design a proper layout for a major exhibition hall in Istanbul.

summary	Architecture took an evolutionary context over time, where designers were interested in finding pragmatic spontaneous appropriate solutions and met the needs of people in urban and architectural spaces. Whereas, in modern architecture an intense and varied competition happens between architects through various currents of thoughts , schools and movements, however, that creativity was the ultimate goal , and a the same time we find that every architect distinguishes himself individually or collectively through tools of architectural expression and design representation adopting a school of thought, using , for example, the leaves of various sizes and diverse technical drawing tools to accurately show that he can be read by professionals or craftsmen outside the geographical scope to which it belongs .With the rapid technological development which accompanied the digital craft in the contemporary world , The digital craft summed up time, distance and tools , so they gave the concept more appropriate accuracy , as virtualization has become the most effective tool for Architecture To reach the ideal and typical results at the practical level, or pure research. At the level of residential design and on the grounds that housing plays an important role in the government policies and given that housing is a basic unit common to all urban communities on earth , the use of different programs to show its typicality in two dimensions or in the third dimension - for example, using software "AutoCAD " " 3D Max " , " ArchiCAD " ... etc. - gave virtualisation smart, creative and beautiful forms which lead to better understand the used /or to be used residential spaces, and thus the conclusion that the life system of dwelling under design or under study , as can specifically recognize spatial structure in housing design - using digital software applying "Space Syntax" for example - in the shadow of slowly growing digital and creative development with the help of high-speed computers . the morphological structure of the dwelling is considered to be the most important contemporary residential designs Investigation through which the researcher in this area aims to understand the various behavioral relations and social structures within the projected residential area, using Space Syntax techniques. Through the structural morphology of dwellings can be inferred quality networks, levels of connectivity and depth and places of openness or closure within the dwelling under study, or under design. How, then, have intelligently contributed this digital craft to the perception of those spatial fixtures ? The aim of this research is to apply an appropriate program in the field of vernacular residential design and notably Space syntax which relate to the understanding and analysis of spatial structures, and also demonstrate its role at the morphological and spatial structure aspects, and prove how effective it helps to understand the social logic of domestic space through social individual/collective relationships and behaviors projected on the spatial configurations of dwellings. The answer to the issue raised above and at the methodological aspect, the study discussed the application of space syntax techniques on the subject. The findings tend to prove the efficiency by comparing samples of Berber vernacular domestic spaces from the Mzab, the Aures and Kabilya in Algeria, and has also led to ascertain the intelligibility of space syntax techniques in reading the differences between the behaviors in domestic spaces in different areas of the sample through long periods of time .

doi	https://doi.org/10.52842/conf.caadria.2014.409
summary	The paper presents the geometrical investigation of a three-dimensional dovetail joint that can lead (timber) frame construction to more than two-dimensional frames; the creation of timber construction with timber members meeting at irregular angles can be shown to be feasible, simplifying overall construction. Traditional joints in timber construction usually work only in two dimensions, in other words in planar surfaces, resulting thus in complicated assemblies in three-dimensions. Stemming from traditional timber dovetail joints, the universal joint under investigation is produced under revolution of the geometry of a dovetail fastener through its middle axis. The resulting concave disk can connect timber elements under irregular angles, without the need for the structural members to lie in the same plane. The joint works due to friction between members rather than using any other element of bonding, allowing for the assembly of joints and structural members with no specialized tools. The paper explores the geometric constraints and degrees of freedom that such a disk creates in timber construction, and consequently in similar linear construction systems.

summary	While the digital era has brought with it a vast assortment of tools from which we can generate form and geometry, often the result is a tendency to focus primarily on either surfaces or solids as a means of modeling for representation or fabrication which consequently impact the various fabrication and construction techniques deployed in order to realize such digital models. This paper presents an approach to coalesce techniques of surface generation via computational tools, and strategies for constructing volumetric elements through a process of backfilling with composite materials.

title	Printing Compound-Curved Sandwich Structures with Robotic Multi-Bias Additive Manufacturing

doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_44
summary	A research team at Florida International University Robotics and Digital Fabrication Lab has developed a novel method for 3d-printing curved open grid core sandwich structures using a thermoplastic extruder mounted on a robotic arm. This print-on-print additive manufacturing (AM) method relies on the 3d modeling software Rhinoceros and its parametric software plugin Grasshopper with Kuka-Parametric Robotic Control (Kuka-PRC) to convert NURBS surfaces into multi-bias additive manufacturing (MBAM) toolpaths. While several high-profile projects including the University of Stuttgart ICD/ITKE Research Pavilions 2014–15 and 2016–17, ETH-Digital Building Technologies project Levis Ergon Chair 2018, and 3D printed chair using Robotic Hybrid Manufacturing at Institute of Advanced Architecture of Catalonia (IAAC) 2019, have previously demonstrated the feasibility of 3d printing with either MBAM or sandwich structures, this method for printing Compound-Curved Sandwich Structures with Robotic MBAM combines these methods offering the possibility to significantly reduce the weight of spanning or cantilevered surfaces by incorporating the structural logic of open grid-core sandwiches with MBAM toolpath printing. Often built with fiber reinforced plastics (FRP), sandwich structures are a common solution for thin wall construction of compound curved surfaces that require a high strength-to-weight ratio with applications including aerospace, wind energy, marine, automotive, transportation infrastructure, architecture, furniture, and sports equipment manufacturing. Typical practices for producing sandwich structures are labor intensive, involving a multi-stage process including (1) the design and fabrication of a mould, (2) the application of a surface substrate such as FRP, (3) the manual application of a light-weight grid-core material, and (4) application of a second surface substrate to complete the sandwich. There are several shortcomings to this moulded manufacturing method that affect both the formal outcome and the manufacturing process: moulds are often costly and labor intensive to build, formal geometric freedom is limited by the minimum draft angles required for successful removal from the mould, and customization and refinement of product lines can be limited by the need for moulds. While the most common material for this construction method is FRP, our proof-of-concept experiments relied on low-cost thermoplastic using a specially configured pellet extruder. While the method proved feasible for small representative examples there remain significant challenges to the successful deployment of this manufacturing method at larger scales that can only be addressed with additional research. The digital workflow includes the following steps: (1) Create a 3D digital model of the base surface in Rhino, (2) Generate toolpaths for laminar printing in Grasshopper by converting surfaces into lists of oriented points, (3) Generate the structural grid-core using the same process, (4) Orient the robot to align in the direction of the substructure geometric planes, (5) Print the grid core using MBAM toolpaths, (6) Repeat step 1 and 2 for printing the outer surface with appropriate adjustments to the extruder orientation. During the design and printing process, we encountered several challenges including selecting geometry suitable for testing, extruder orientation, calibration of the hot end and extrusion/movement speeds, and deviation between the computer model and the physical object on the build platen. Physical models varied from their digital counterparts by several millimeters due to material deformation in the extrusion and cooling process. Real-time deviation verification studies will likely improve the workflow in future studies.

summary	This paper will present the main principles of Goethe’s Theory of Colours and formulate a theoretical approach for the study of polychromy in digital design pedagogy. In the first part of the paper a survey on colour theory will be presented comparing Goethe and Newton’s works on colour. The concepts of polarity [Polarität] and intensification [Steigerung] will be introduced as the two main principles of Goethe’s dynamic notion of colour. These terms will be used to explain how Goethe considered colours to induce sensual effects on the onlooker. In the second part a digital design studio that focuses on colour will be presented. The pedagogy will show how a dynamic notion of colour could be studied using digital tools. Some of the student works will be presented while addressing how a Goethean notion of sensual colours could be studied as spatial parameters. The goal of the paper is to distill a theoretical approach towards the study of colour in architecture and contemplate on how it could be applied within the digital design curriculum.
