title Gesture Modeling – In Between Nature and Control
source Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 189–198

summary This research develops a robotic arm-controlled wax material fluidity shape/form-making system that combines AI image recognition and remote control capabilities. AI image recognition is used to capture the designer's hand gestures or movements as an intuitive input method for controlling shape forming. It gives the designer active control of the desired model shape through the temperature, rotation, and movement controls in the process of phase change of wax materials. The system has the additional advantage of remote control, allowing designers to create wax models remotely through intuitive gesture-controlled interactions. This advantage will become a new method of the digital co-creation process.

title From Pencil to Pixel: The Evolution of Design Ideation Tools
source Nicole Gardner, Christiane M. Herr, Likai Wang, Hirano Toshiki, Sumbul Ahmad Khan (eds.), ACCELERATED DESIGN - Proceedings of the 29th CAADRIA Conference, Singapore, 20-26 April 2024, Volume 3, pp. 89–98

summary This study explores the integration of Artificial Intelligence-Generated Content (AIGC) in design processes, focusing on the ideation phase. Utilizing in-depth interviews with experienced designers and an experimental approach with novices, it compares AIGC tools like ChatGPT, Midjourney and Copilot with traditional sketching methods. The findings reveal two distinct operational patterns in AIGC utilization: a subtractive method of refining AI outputs and an additive method of evolving design through AI suggestions. Experienced designers view AIGC as a powerful aid for creative ideation, while novices prefer familiar hand-drawing methods. The study proposes a "Seeing-Instructing-Seeing" model, adapting Schön's reflective practice model, to incorporate the collaborative dynamic between designers and AI, marking a shift from manual to intellectual labor in design ideation. This represents a paradigm shift in design methodologies, suggesting a future of co-creative partnerships between designers and AI tools.

title Let’s Work Together: A Stigmergic Approach to Acoustic Design
source ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 396-403
doi https://doi.org/10.52842/conf.acadia.2011.396
summary This paper explores the application of agent-based modeling techniques to the domain of acoustics design. Concepts derived from Stigmergy, which is a class of mechanisms that mediate interactions between social organisms, are applied to a custom implementation of a raytracing based acoustics simulator. Rays are given the agency of changing the geometric and material properties of the surfaces they come in contact with during the raytracing phase. The acoustic simulation process is an active one, where the modeled room environment is adapted while being evaluated. Given performance criteria as input, the simulation process is applied to an auditorium example. The auditorium is adapted and its eventual emergent design has improved acoustic performance. It is hoped that this work will demonstrate the potential of coupling multi-agent systems with simulation processes in order to create new design tools.

title Robotic Metal Aggregations

summary The recent convergence of computational design and digital fabrication has made new forms of architectural materialization possible. A workshop conducted at the Royal Melbourne Institute of Technology investigated how differentiated lightweight metal structures may be designed and fabricated under these new conditions. The workshop aim was to complete three such structures; each one is aggregated from aluminum profiles that are robotically assembled according to computationally driven geometric logics. The key challenge was to enable participants, assumed to lack programming and robotic fabrication experience, to design and construct their structures within imposed time constraints. This paper describes the subsequent development of accessible computational design tools and a robust robotic fabrication method for the workshop, and highlights the key decisions taken with their implementation. The workshop results are discussed and the design tools evaluated with respect to them. The paper concludes by recommending an approach to developing computational design tools which emphasizes the importance of usability and integration with the fabrication process.

title A Software Environment for Designing Through Robotic Fabrication – Developing a Graphical Programming Toolkit for the Digital Design and Scaled Robotic Fabrication of High Rises
source Open Systems: Proceedings of the 18th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2013) / Singapore 15-18 May 2013, pp. 45-54

summary The term “robot” was born from a play written almost a century ago. Today robotic fabrication has become an emerging topic in architectural research. As architects work with these technologies, they are challenged with writing a different kind of play: here robots are the actors and the physical materialization of a design is their performance. However current Computer Aided Design (CAD) packages do not provide native robot programming functionalities which architects require to plan and orchestrate these fabrication process. To address this limitation, a Python library for robot programming is written. It is referenced by a toolkit of custom components developed to extend a graphical programming environment commonly used for architectural design. The empirical development of these software tools takes place in the context of a design studio investigating the subject of the high rise. The tools are tested in a workflow that involves the digital design and scaled robotic fabrication of high-rise housing. This paper discusses the considerations underlying the toolkit’s design, the outcomes of its use in the studio, and its impact on the creative design process.

summary Existing buildings are often lacking BIM models. This paper proposes a method to semi-automate the generation of BIM models from 2D CAD drawings. The method has two parts: the first part, 2D CAD drawing preparation, involves cleaning the drawings to obtain simplified 2D input geometry and the second, 3D BIM model generation, involves generating and extracting parameters to generate 3D BIM components. This research focuses on the semi-automation of the second part. The the model is generated storey by storey, with each building element type being processed. A demonstration was carried out for a case-study building. The main modelling strategies used by the method are described and key challenges are discussed.

title Shape Exploration in Design: Formalising and Supporting a Transformational Process
source International Journal of Architectural Computing vol. 6 - no. 4, 415-433
summary The process of sketching can support the sort of transformational thinking that is seen as essential for the interpretation and reinterpretation of ideas in innovative design. Such transformational thinking, however, is not yet well supported by computer-aided design systems. In this paper, outcomes of experimental investigations into the mechanics of sketching are described, in particular those employed by practicing architects and industrial designers as they responded to a series of conceptual design tasks. Analyses of the experimental data suggest that the interactions of designers with their sketches can be formalised according to a finite number of generalised shape rules. A set of shape rules, formalising the reinterpretation and transformations of shapes, e.g. through deformation or restructuring, is presented. These rules are suggestive of the manipulations that need to be afforded in computational tools intended to support designers in design exploration. Accordingly, the results of the experimental investigations informed the development of a prototype shape synthesis system, and a discussion is presented in which the future requirements of such systems are explored.

title Programação em plataforma BIM e a Norma de Desempenho Brasileira: Desenvolvimento de uma aplicação para estimativa de performance acústica em projetos arquitetônicos [BIM platform programming and Brazilian Performance Standard: Development of an application to estimate acoustic performance in architectural design]
source SIGraDi 2017 [Proceedings of the 21th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-227-439-5] Chile, Concepción 22 - 24 November 2017, pp.423-428
summary The Brazilian Performance Standard (NBR 15.575/2013 – Housing Buildings – Performance) is changing the design process of residential buildings, imposing new acoustic performance criteria. In this Context, the present paper proposes the programming of a Revit plug-in for verifying sound insulation of walls between environments, collecting information of the building’s model from a parameter database, calculating values of the elements’ sound reduction index and allowing to ponder constructive systems’ performance. The application aims to amplify productivity of designers and to provide greater control over technological solutions, assisting in the compliance with performance criteria.

summary Hospitalization is, for the patient, a neuropsychophysiological stressor, thus pertinent theories point to architectural stimuli as a tool for the homeostasis restoration and consequent well-being. Furthermore, they compile advantages to the patients’ treatment and highlight, mainly, the natural environments benefits, which is elucidated by the Biophilia theory. Through literature review and analysis of applied research in national and international hospitals, extracted from indexing databases of scientific production in the 2000-2020 timeframe, it was found that these areas [a] promote stimuli that enhance emotions and positive feelings; [b] act to restore stress and anxiety; [c] reduce pain, analgesic intake and length of stay; and [d] increase patient satisfaction. By sharing the results of this research, the objective is, in addition to stimulating future research on the organism behavior in the environments, to indicate perspectives for hospital ambiences.

summary This paper presents a discussion about design pedagogy strategies focused on students’ processes rather than on their architectural objects. The hypothesis here is that critical and creative autonomy of students can be developed by the teaching of design thinking simultaneously with operative digital tools within design disciplines. An experiment was made in an introductory design discipline in a private Brazilian Architecture School and results show how students’ skills and knowledge about design grow faster when a digital creative culture is fostered within the design studio.

summary In order to design an ephemeral pavilion located at the Serpentine Gallery (England), an experimental design approach was developed in this paper by using biomimicry strategies associated with parametric modeling. Exploring the solution-based methodology, the analysis of the sartorius muscle anatomic features such as rotation, flexion and long shape allowed inspiring the proposal of a Sartorius Pavilion which is the object of study. The experiment was implemented throughout a parametric visual script tool resulting in a model capable of rapidly and intuitively simulating shape variations, basic structural and material attributes by modifying a set of previously defined parameters.

title Algorithmic approach toward Transit-Oriented Development neighborhoods: (Para)metric tools for evaluating and proposing rapid transit-based districts
source International Journal of Architectural Computing vol. 14 - no. 2, 131-146
summary This article focuses on the use of computational tools to provide dynamic assessment and optimized arrangements while planning and discussing interventions in urban areas. The objective is to address the use of algorithmic systems for generating and evaluating urban morphologies guided by Transit-Oriented Development principles. Transit- Oriented Development is an urban development model that considers geometric and measurable parameters for designing sustainable cities. It advocates compact mixed-use neighborhoods within walking distance to a variety of transportation options and amenities, seeking to result in optimized infrastructure provision and energy-efficient low- carbon districts. This article presents algorithmic experiments for the optimization of a rapid transit district, through its urban morphology and services’ location, providing an accurate Transit-Oriented Development modeling. The main findings of this study highlight that the combination of Transit-Oriented Development and algorithmic–parametric tools has the potential to significantly contribute to a process of responsible planning and, ultimately, to mitigate global warming.
