summary	This is a case study of teaching at the University of Texas at Austin. It is about using an electronic design studio to provide architecture students with their first exposure to computing. It suggests that, despite the limitations of present technology, there is reason to lower the thresholds to computer-aided design. The study presents a studio which attempted such by allowing students to find their own level of commitment to use of electronic media for geometric modeling. More generally, the paper aims to document issues presently facing the many professional schools not having substantial traditions in computer-aided design education.

title	Glass Cast: A Reconfigurable Tooling System for Free-Form Glass Manufacturing
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. 287-294

summary	Despite glass’s ubiquity in the modern built environment it is rarely applied in applications requiring complex curvature. The high temperatures and complexity of techniques utilized in forming curved glass panels are typically very expensive to employ, requiring dedicated hard-tooling which ultimately limits the formal variation that can be achieved. This combination of economic and manufacturing barriers limits both the formal possibilities and potentially the overall envelope-performance characteristics of the glazing system. This research investigates a methodology for utilizing reconfigurable tooling to form glass into doubly curved geometries, offering the potential for improved structural and environmental performance in a material that has remained largely unchanged since the advent of its industrial manufacturing. A custom built forming kiln has been developed and tested, integrated through a parametric modeling workflow to provide manufacturing constraint feedback directly into the design process. The research also investigates the post-form trimming of glass utilizing robotic abrasive waterjet cutting, allowing for the output of machine control data directly from the digital model. The potentials of the methodologies developed in this process are shown through the fabrication of a full-scale installation. By integrating material, fabrication, and design constraints into a streamlined computational methodology, the process also serves as a model for a more intuitive production workflow, expanding the understanding of glass as a material with wide-ranging possibilities for a more performative architecture.

title	The Thousand-Acre Sketch Problem
source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 427-440
summary	An unusually large sketch problem in urban design was given to an undergraduate studio class to introduce visualization techniques and to explore fundamental urban design principles. This thousand-acre sketch problem was distributed to students on a floppy disk as a three- dimensional computer model. The availability of a large number of Macintosh IIs and access to a pre-release version of the three-dimensional modeling program ModelShop allowed us to conduct this prototype electronic studio. This paper looks at the productivity gains experienced by our students during this project and discusses the increased level of understanding witnessed in student performance. More importantly, this sketch problem is examined as a philosophical parable for several pedagogical issues of design education in the microcomputer age.

title	IFS-Based Computational Morphogenesis of a Hierarchical Trussed Beam
source	Ji-Hyun Lee (Eds.) "Hello, Culture!" [18th International Conference, CAAD Futures 2019, Proceedings / ISBN 978-89-89453-05-5] Daejeon, Korea, pp. 552-564
summary	This paper applies IFS (Iterated Function System) as a rule-based computational modeling process for modeling a hierarchical truss beam inspired by the concept of fractal geometry. IFS is a type of recursive algorithm, which repeatedly uses the outcome as a input for an affine transformation function in generating a fractal shape, i.e., a complex shape which contains the self-similar repetitions of the overall shape in its parts. Hierarchical trusses also follow a similar geometric configuration. IFS-based computational modeling, hence, allows us to parametrically morph a parent model, thus repeat the same morphing to all its self-similar parts automatically. This IFS-based morphogenesis opens a possibility to find an optimal configuration of a hierarchical truss structurally. In this parametric modeling process, the iteration number is a unique geometric parameter. This paper uses two geometric variables (iteration number and angle) to find the most efficient design of a hierarchical truss beam through an optimization process.

summary	3D printing offers significant geometric freedom and allows the fabrication of integral parts. This research showcases how robotic fused deposition modeling (FDM) enables the prefabrication of large-scale, lightweight, and ready-to-cast freeform formwork to minimize material waste, labor, and errors in the construction process while increasing the speed of production and economic viability of casting non-standard concrete elements. This is achieved through the development of a digital design-to-production workflow for concrete formwork. All functions that are needed in the final product, an integrally insulated steel-reinforced concrete wall, and the process for a successful cast, are fully integrated into the formwork system. A parametric model for integrated structural ribbing is developed and verified using finite element analysis. A case study is presented which showcases the fully integrated system in the production of a 2.4 m tall x 2.0 m curved concrete wall. This research demonstrates the potential for large-scale additive manufacturing to enable the efficient production of non-standard concrete formwork.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	This report examines the application of physical models and digital ones as tools in the design of reinforced concrete shells. The development of computational processes and consequently the process of analyzing the structure as the finite element method allows more complex forms to be applied in architectural projects. The research demonstrates the potential of this tool, through the analysis of contemporary projects such as the “Memorial da America Latina” of Oscar Niemeyer, with modeling of the structure in ANSYS.

title	Leaf Coverage Quantification for the Design of Vegetated Shading Geometries Using Algorithmic Modeling, Coupled with Imaging Software
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 1463–1473
summary	One of the most significant parameters for obtaining positive benefits from vegetation is the leaf area index. This parameter influences the shading of the plant, acting as a solar control device in the architecture. In this sense, this work aims to collect average parameters of the percentage of leaf cover of climbing species, in a high tropical climate, through digital mapping and pixel counting, using the image software ImageJ for digital image processing and analysis. With these parameters, it will be possible to simulate the shading of the vines and predict their growth. This simulation can help designers make decisions such as mesh configurations, planting spacing, and regular maintenance. The research hopes to fill a gap in the literature on specific data on leaf cover of climbing species, which can serve as an input to the algorithmic modeling of green facades in architecture.

title	Synchronous Horizons: Redefining Spatial Design in Landscape Architecture Through Ambient Data Collection and Volumetric Manipulation
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. 355-361
doi	https://doi.org/10.52842/conf.acadia.2012.355
summary	The premise of this paper addresses the limited shared vocabulary of landscape architecture and architectural design - evident in the application of terms such as ‘spatial design’ and ‘spatial planning’. In their current usage, such terms emphasize the visible, terrestrial, pedestrian perspective level, often to the absolute exclusion of a spatial, ie. volumetric, comprehension of the environment. This deficit is acutely evident in the education of Landscape Architecture and Architecture, and discussion of their shared ground. The dominant document to map such analysis and design is the plan, or 3d-dimensional representations of the same, restricted to an extrusion or height map. GIS techniques in spatial design tend to be weighted towards visual, surface based data (slope analysis, exposure, viewshed etc.). Our goal within this domain lies in transforming aspects of the intangible - the characteristics of open space itself - into a form that is legible, quantifiable, and malleable.

summary	The integration of VR in the creative process has caused a profound shift in the use of modeling tools and abstraction. How do instantaneous experiential feedback, body awareness, the triggering of spatial sensations, and traveling in real-time from an object-scale to a habitable-scale affect modeling in VR? This research explores the tensions and exchanges between the physical and the digital relative to spatial perception when designing in VR. The work produced by participants involved in a digital design workshop developed around these topics will be presented. In response to a written provocation, participants modeled three-dimensional dreamscapes in VR using Oculus Medium. Participants explored the connection between the body and its movements to measure, model, and control phenomena when animating virtual scenes. This research contributes to the teaching and implementation of modeling in a virtual environment by exploring the inherent possibilities of VR in relation to the conceptualization of spaces.

title	Analysis and validation of the digital chain relating to architectural design process: Achievement of a folded structure composed of wood panels
source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 447-459.
summary	The research presented in this paper revolves around the experimental development of the morpho-structural potential of folded architectural structures made of wood. The aims are to develop an innovative system for timber used in sustainable construction and to increase the inventory of wood architectural tectonics. First, this article provides a characterization of the digital chain associated to the development of non-standard folded structures consisting of wood panels. The purpose is to study the architectural design process from parametric modeling (through CNC machining) and assembly operations to production by way of a full-scale experimental pavilion. Secondly, a number of analytical experiments have been performed towards the completion of the pavilion, in order to validate the design process.

title	Computational urban design prototyping: Interactive planning synthesis methods—a case study in Cape Town
source	International Journal of Architectural Computing vol. 16 - no. 3, 212-226
summary	This article is motivated by the fact that in Cape Town, South Africa, approximately 7.5 million people live in informal settlements and focuses on potential upgrading strategies for such sites. To this end, we developed a computational method for rapid urban design prototyping. The corresponding planning tool generates urban layouts including street network, blocks, parcels and buildings based on an urban designer’s specific requirements. It can be used to scale and replicate a developed urban planning concept to fit different sites. To facilitate the layout generation process computationally, we developed a new data structure to represent street networks, land parcellation, and the relationship between the two. We also introduced a nested parcellation strategy to reduce the number of irregular shapes generated due to algorithmic limitations. Network analysis methods are applied to control the distribution of buildings in the communities so that preferred neighborhood relationships can be considered in the design process. Finally, we demonstrate how to compare designs based on various urban analysis measures and discuss the limitations that arise when we apply our method in practice, especially when dealing with more complex urban design scenarios.

summary	This paper discusses our ongoing research into hierarchical volumetric modeling and the external forces which are motivating a shift from the traditional boundary representation (also known as BREP) that has thus far dominated design software toward a more flexible voxel-based representation capable of describing complex variable material distributions. We present Monolith; a volumetric modelling application which explores hybrid forms of digital representations and new design workflows that extend a designer's ability to describe the material properties of a 3d model at the mesoscopic and even microscopic scales. We discuss the inherent complexities in volumetric modelling and describe the design opportunities which heretofore were unavailable using existing techniques.

doi	https://doi.org/10.52842/conf.acadia.2013.043
summary	At present, computer aided design (CAD) software has proven ill equipped to manage the spatial variations in material properties. Most digital design packages employ a surface modeling paradigm where a solid object is that which is enclosed by a set of boundaries (known as boundary representations or “B-rep” for short). In surface models, material representations are often treated as homogenous and discrete. Yet, natural materials are capable of structures where the variability of material within a volume is defined at a multiplicity of scales and according to various functional criteria. With the advent of new 3D printing techniques, a new possibility emerges—allowing new multi-material composite objects to be fabricated in a single build volume with a high degree of dimensional accuracy and repeatability. However, a big limitation facing complex high resolution digital fabrication comes from the software’s inability to represent or handle material variability. This paper proposes a new digital interface for working with multi-material distributions at a variety of scales using a rasterization process. Beyond the immediate benefit of precise graduated control over the material distribution within a 3D printed volume, our interface opens new creative opportunities by enabling the use of existing image processing techniques (such as filtering, mapping, etc.) which can be applied to three-dimensional voxel fields. Examples are provided which explore the potential of multi-scale material distributions.

title	A NEW SCANNING SKY SIMULATOR
source	Proceedings of the 4rd European Full-Scale Modelling Conference / Lausanne (Switzerland) 9-12 September 1992, Part B, pp. 43-48
summary	A sky simulator has been developed to study daylighting systems on scale models (diffuse component of daylight). This apparatus is of a completely new concept (scanning sky simulator) and has numerous advantages in comparison with similar devices. It allows in particular the reproduction of any sky condition and distinguishes itself by easy calibration, reduced maintenance and moderate electric consumption. The simulator is equipped with a measuring and visualisation system which allows the user to simultaneously carry out quantitative studies (profile of daylight factors) and qualitative studies (visual lighting effects). In this paper, a description of the system and its functioning as well as an application example are given.

summary	Disability is a product of the interactions between individuals and the environment they inhabit and the products they utilize. Disability is located on a continuum from enablement to disablement. Human physical characteristics as well as environmental factors will locate an individual on that continuum. The degree of disability or enablement will fluctuate, depending upon the attributes of the environment and the artifacts located there. The ability of designers and architects to create environments and products that enable all people is directly tied to their ability to: 1. understand the abilities and constraints of the human body and, 2. model the physics of the body’s interactions with artifacts and spaces. // This project is developing an anthropometric measurement protocol and computer-based design tools focusing on people with disabilities and the aging. The areas of interest for measurement are guided by real-world design needs. The measurements generated are translated into three-dimensional datasets compatible with commercial off the shelf software extended by the programming of additional scripts, functions, plug-ins, behaviors, etc.

summary	This paper presents a description of ISAAC; the Immersive Simulation Animation And Construction program designed and built at the University of North Carolina atChapel Hill (UNC-CH). ISAAC is a scene composition application used for the interactive construction of virtual worlds. In ISAAC you work directly in a virtualenvironment; you position, orient and scale objects using direct and indirect manipulation techniques. ISAAC stores object configurations in ASCII files that it uses torecreate scenes at a later date for further manipulation and interactive exploration. ISAAC is not a modeling program; you create worlds by manipulating pre-generatedthree-dimensional models (which can come from sources such as computer-aided design programs or three-dimensional scanning devices). ISAAC was designed toovercome some of the limitations of working in a virtual environment and to take advantage of the natural and intuitive forms of interaction available in a virtual world.
