title	Concepts and Methodologies for Multiscale Modeling: A Mesh-Based Approach for Bi-Directional Information Flows
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. 308-317

summary	This paper introduces concepts and methodologies for multiscale modeling in architecture, and demonstrates their application to support bi-directional information flows in the design of a panelized, thin skinned metal structure. Parameters linked to the incremental sheet forming fabrication process, rigidisation, panelization, and global structural performance are included in this information flow. The term multiscale refers to the decomposition of a design problem into distinct but interdependent models according to scales or frameworks, and to the techniques that support the transfer of information between these models. We describe information flows between the scales of structure, panel element, and material via two mesh-based approaches. The first approach demonstrates the use of adaptive meshing to efficiently and sequentially increase resolution to support structural analysis, panelization, local geometric formation, connectivity, and the calculation of forming strains and material thinning. A second approach shows how dynamically coupling adaptive meshing with a tree structure supports efficient refinement and coarsening of information. The multiscale modeling approaches are substantiated through the production of structures and prototypes.

title	Designing for Pedestrians : A CAD-Network Analysis Approach
source	New York: John Wiley & Sons, 1992. pp. 379-398 : ill. includes a short bibliography
summary	Microcomputer techniques have been developed that combine CAD drawings with transportation network analysis software that uses spreadsheets and stand-alone programs activated from the DOS operating system. The CAD feature simplifies and improves the methods used to design pedestrian circulation facilities and evaluate the impact of new development on existing pedestrian flows. Through the use of customized software, the need for manual data entry is reduced, and the graphical display of analysis results in most intermediate steps in the process are automated. Three hypothetical case studies are presented, concentrating on proposed pedestrian circulation improvements at Penn Station, New York

title	Rectangular V-Splines
source	IEEE Computer Graphics and Applications. February, 1986. vol. 6: pp. 35-40 : ill. some col. includes bibliography
summary	This article describes and presents examples of some techniques for the representation and interactive design of surfaces based on a parametric surface representation that uses v-spline curves. These v-spline curves, similar in mathematical structure to B-splines, were developed as a more computationally efficient alternative to splines in tension. Although splines in tension can be modified to allow tension to be applied at each control point, the procedure is computationally expensive. The v-spline curve, however, uses more computationally tractable piecewise cubic curves segments, resulting in curves that are just as smoothly joined as those of a standard cubic spine. After presenting a review of v-splines and some new properties, this article extends their application to a rectangular grid of control points. Three techniques and some application examples are presented

summary	Flexible mass customization of buildings is still in its infancy. Current systems for the automated support of ownerdriven configuration management are limited with regard to the degree of freedom they offer to end-users, due to the lack of an easy way to specify those freedoms. In this paper we present the prototype of an interface that allows architects to define constraints to which user-customized dwellings must conform.

summary	Flexible mass customization of buildings is still in its infancy. Current systems for the automated support of owner-driven configuration management are limited with regard to the degree of freedom they offer to end-users. In this paper we present and discuss a constraint definition and verification system that allows the architect to specify boundary conditions within which the client can vary the design. The required constraint grammar is presented and applied to a real-world building code. A 2D floor plan prototype is tested to reveal the methodological and technical issues to be solved to make a step forward.

summary	In the context of activity-based transport simulation models, multi-day activity planning is receiving increasing attention. The aim of this paper is to develop and illustrate an extension of a needs-based model of activity generation that takes into account possible influences of pre-planned activities and events. This paper describes the theory and shows the results of simulations of the extension. The simulation was done for six different activities and different parameter values. The results show that the model works well and the influences of the parameters are clear and seem logical.

title	Smart Cloud-of-Points Model: Point-based Digital Media and Tools for Architectural Design
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 687-694
doi	https://doi.org/10.52842/conf.ecaade.2005.687
summary	Abandoning the scale-model concept in favor of an abstract representation led us to the development of a digital design model based on point-clouds as design media. In this paper we examine the potential usage of point-clouds as design media. Extending the point-cloud model with a forth dimension represented as a numeric pointer to generative algorithms provides a parametric interface for the regeneration and alteration of the extended point-cloud model referred to as “Smart Cloud of Points”.

doi	https://doi.org/10.52842/conf.ecaade.2006.763
summary	This paper presents an innovative approach towards parametric design. The use of histograms is suggested as a design interface representing the spatial parametric relationships in an unfolded tabular form. The unfolded tabular and bar histogram provides a schematic representation of the design model and allows creating parametric relationships between the design components.

source	International Journal of Architectural Computing vol. 5 - no. 1, pp. 46-59
summary	This paper presents an innovative approach towards parametric design using point-clouds as design media. Exposing the internal numeric representation of digital models led to the development of parametric point-clouds as design drivers. A parametric point-cloud concept is presented in this paper, exploring its potential application for behavior modeling, generative design and performance-driven design of building envelopes.

title	O conceito de Performance e sua apropriaç?o no campo do Design Computacional [The concept of Performance and its appropriation within the Computational Design field]

summary	This paper attempts to discuss about the notion of performance within the architecture and computational design fields. Recently, many projects and academic research have been conducted based on the so-called performance-oriented-design process, especially when operating with digital tools. However, not so much effort has been put into understanding the performance concept itself and all its semantic possibilities. Throughout brief etymological investigation, historical research, and literature reviews, this article intends to contribute to developing new approaches towards performance design.

title	The study of Urban Acoustics through Digital Processes: New approaches to developing a Methodology
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 1 - ISBN: 978-85-8039-135-0] Florianópolis, SC, Brasil 23-27 November 2015, pp. 378-383.
summary	This paper aims to discuss different possibilities and methodologies within the field of urban acoustics and the use of digital tools. As an attempt to integrate quantitative methods, such as sound mapping and noise control, with qualitative approaches, such as the soundscape studies, new strategies based on performance oriented design will be addressed. The notion of sonic effect as an important tool for integrating different perspectives will hence be discussed as a possible instrument for structuring generative design experiments. A theoretical framework and a possible design workflow are further drawn to possibly articulate future studies.

title	Collaborative Design Knowledge Construction and Measuring Shared Understanding
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Progress in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN-10: 90-386-1756-9, ISBN-13: 978-90-386-1756-5, p. 303-312
summary	This paper describes a pilot test conducted as part of the ongoing research project. The performed pilot test describes the collaborative knowledge construction under two conditions: i) Collaborative knowledge construction in a traditional brainstorm setting ii) Collaborative knowledge construction in a proposed method (section number) described further in the paper. The pilot test focuses on measuring the shared mental model of a multi-disciplinary design team involved in a problem solving session. The approach to the study to predict shared understanding was to measure overlapping of mental models on a set of concept construct pairs of individuals during the design session. The findings of the pilot test were that the shared understanding in the proposed condition was better compared to the traditional means of brain storming.

title	Drama and Context in Real-Time Virtual Environments: Use of Pre-Scripted Events as a Part of an Interactive Spatial Mediation Framework
source	TIDSE ’03 Technologies for Interactive Digital Storytelling and Entertainment, S.Goebel, N.Braun, U.Spierling, J.Dechau, H.Diener (eds.) Darmstadt, Germany, 24-26 March 2003. Fraunhofer IRB Verlag, Stuttgart, ISBN 3-8167-6276-X, pp. 296-310
summary	We suggest that the dramatically engaging mediation of an experience of place should be built in as a fundamental capability of a compelling and meaningful virtual environment (VE). Our main objective is to develop flexible interactive techniques that supply VE’s with a coherent context and make the resulting ‘virtual place’ available to the user in a dramatically engaging way. To support the concept of narrative expressive space, we propose a three-layer multi-purpose spatial mediation framework that utilizes an interactive narrative structure to coordinate stylized dramatic camera work, lighting, effects and sound. We then describe the use of pre-scripted events as a layer in this framework and explain the inherent benefits and problems, using a single-user prototype environment as illustration. The work offers guidelines for the design of VE’s to all fields that combine narrativity and spatiality, such as interactive entertainment, education and architecture.

title	Robotic Crocheting: From Handcraft to Digital Fabrication
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. 191–200
doi	https://doi.org/10.52842/conf.caadria.2023.2.191
summary	There is growing interest in incorporating digitally fabricated textiles into architecture. While most studies have addressed knitting and yarn winding, only a handful have involved crocheting. Crochet is a traditional handcraft that uses a hook to create fabric from a single yarn. Crochet is exceptional in its capability of creating seamless complex 3D shells. Despite significant progress attained in the computation of crocheting instructions, which positions it in an additive manufacturing context, a rigorous fabrication solution for crochet is still lacking. The present study examines the possibilities of applying additive manufacturing principles for adapting crochet from handcraft into digital fabrication using a robotic arm. The experimental phase focuses on toolpath design, targeting the primary steps involved in the performance of crochet stitches using a robotic arm. Initial stages include a manual scheme, using 3D-scanned pre-prepared cloth as a foundation for path design, and recording the crochet hook path in digital format. This study defines the first steps in transitioning crochet from handcraft to a robotic process and establishes the method's feasibility based on the computational design of the tool path. Robotic crochet enables the production of remarkably complex seamless 3D textiles in large-scale formats and opens the field to architectural applications.

summary	In an effort to sustain and revitalize the dying craft of wire-bending, I present the development of three novel approaches: Digital Crafting, Computational Crafting, and Crafting Fabrication. Computation and digital technology were integrated with traditional wire-bending principles to design and fabricate artifacts. In this work, I present three artifacts resulting from these novel approaches, and analyze how these methods may be used in design education and practice. Our findings benefit the practice because it offers opportunities for teaching computational and traditional skills to older and younger generations through wire-bending.

summary	This paper describes a new approach to designing and fabricating costuming and dancing sculptures and the potential application of this system at the architectural scale. I present a novel design system based on the movement, form, and spatial relation of characters and dancing sculptures in the Trinidad Carnival. I also present a system that produces lightweight mobile structures from 3D printed connections, lightweight rods, and textile. Through a detailed case study, a new dancing sculpture is designed, and a full-scale lightweight mobile structure at the architectural scale is fabricated. Fabrication of the lightweight structure is achieved using Digital Crafting and Crafting Fabrication approaches to wire-bending, which includes the early development of a digital fabrication program for rod elements. This work has potential implications for costuming and dancing sculptures; architecture; computational design; and craft practices.
