summary	Hybrid robot systems that cooperate with live organisms is an active area of research, in part to leverage biological advantages such as adaptivity, resilience, and sustainability. Formica Forma explores new possibilities of codesigning and cofabricating in partnership with Western Harvester ants to build forms that would be challenging with industrial techniques. Using a robotically controlled UV light (350–405 nm) as an environmental stimulus to bias digging behavior, we guide 600 ants to dig ~141 cm of tunnels in transparent ant gel over 646 hours. Predictability, fidelity to the UV source, repeatability, dig efficiency, amount of ant activity, and tunnel preference were studied. The resulting branching tunnels were cast in silicone to demonstrate the ability to harness this in subtractive fabrication with inexpensive, self-maintaining biological fabricators. Results showed that ants can follow the UV light as a path guide (when the light is moving) or target it as a goal (when the light is both moving and static), with longer digging effect from the moving UV stimulus. Ants showed high fidelity to the light path, aligning their tunnel direction exactly with changes in the UV position, tuning the fabrication in real-time with environmental alterations. Population size did not seem to affect digging speed or efficiency, and the ants’ preexisting preferences factored into which tunnels were dug out. The research develops a hybrid biodigital way of working with biological swarms where the individual agency and the intrinsic stochasticity of the system offer possibilities in real-time adaptability and programmability through environmental templating.

title	Extracting Actionable Information from the Site Context Using A Phenotype-Based Strategy
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 1, pp. 323–332
doi	https://doi.org/10.52842/conf.caadria.2024.1.323
summary	As more computational design tools are developed, solution generation has been accelerated to provide real time feedback. However, a human designer is still required to translate generated data into actionable information. This is especially so for diverse design scenarios, where the data structure differs, and the computer is unable to draw conclusions across both scenarios. The site context is one key parameter that contributes towards the difference in scenarios. In short, how can an algorithm extract design-related information from diverse scenarios? To address this issue, a phenotype-based strategy is proposed as a representation method, and it re-parameterises diverse site conditions by focusing on their geometrical properties. Instead of parameterising the site context, street-view images are captured, and Gabor filters extract relevant geometrical properties, such that site conditions with different compositions, forms, and density can be organised. This method quantifies compositional and density-based properties of the surrounding building blocks, thereby enabling the computer to digest generated information and provide design suggestions. A new sample site is then used to demonstrate a query of the phenotype space, where suggestions about solar radiation performance is feedback to a human designer.

title	Using Shape Grammar to design ready-made housing for humanized living. Towards a parametric-typological design tool
source	SIGraDi 2011 [Proceedings of the 15th Iberoamerican Congress of Digital Graphics] Argentina - Santa Fe 16-18 November 2011, pp. 78-81
summary	The research described in this paper is part of a larger on-going project called "Emerg.cities4all" that proposes a generative computer-aided planning system for housing for low-income populations using shape grammars. This paper presents the preliminary research results of a group of four master students who proposed to develop a grammar of ready-made housing for humanized living based in three informal settlements case studies. The results of this research are based on the assumption that it is possible to generate modular, adaptable and affordable ready-made housing for humanized living solutions design, supported by a computational generation tool.

summary	The prevalent use of inorganic, non-local materials in construction and design in the age of ecological crisis, calls for experiments with new, more sustainable components. In this research, we suggest re-thinking the incorporation of flora in design, by developing a new material for additive manufacturing (AM), that utilizes the constructive potential in the root entanglement of germinating seeds. The material which is comprised of a hydrogel and seeds is used to create 3D printed objects. These transform over time and the material receives new properties and qualities. The seeds develop into plants which finally wither, the plants roots intertwine and strengthen the structure of the designed shape as the sustaining hydrogel disintegrates. The object is comprised of organic biodegradable components only, that can be prepared for AM in simple processes. By doing so, the result is an accessible method of creating plant based and digitally designed objects. Our research challenges the conventional approach for integrating nature into the built environment. While flora is most commonly subsequently added as an external addition to the designed object, in this work, seeding is an integral part of the fabrication process. This allows us to introduce a new workflow for ecological design and fabrication.

title	BATHROOM DESIGN AND FUNCTION ANALYSIS - BRIEF REPORTS FROM TWO RESEARCH PROJECTS
source	Proceedings of the 3rd European Full-Scale Modelling Conference / ISBN 91-7740044-5 / Lund (Sweden) 13-16 September 1990, pp. 38-39
summary	The problem behind this research project was the fact that Swedish standard bathrooms were (and most of them still are) difficult to clean, because of the building design. This has consequences not only for the inhabitants but also for the home helpers who assist old and disabled people in their own dwellings. The most difficult-to-clean spaces in a dwelling are the bathroom and the toilet-room. These spaces also are the most dirtied. In Sweden there of ten is a toilet in the bathroom. The aim of the project was to find out what or how much of physical agility a Swedish standard bathroom demands from the person who carries out the cleaning of it.

title	Virtual Building Lifecycle - Giving architects access to the future of buildings by visualizing lifecycle data
source	ICCCBE8, Stanford, August 2000
summary	Today’s software for architects and civil engineers is lacking support for the evaluation and improvement of building lifecycles. Facility Management Systems and 4D-CAD try to integrate lifecycle data and make them better accessible, but miss the investigation of the development of the structure itself. Much money is inappropriately spent when materials with different life expectancies are combined in the wrong way and building parts are repaired or replaced too early or too late. With the methods of scientific visualization and real-time 3Dgraphics these deficiencies can be eliminated. The project “Virtual Building Lifecycle” (short VBLC, [W-VBLC]) connects 3D geometrical information to research data such as life expectancy and emissions and to standard database information like prices. The automated visualization of critical points of the structure in the past, presence and future is a huge advantage and helps engineers to improve the duration of the lifecycle and reduce the costs.

summary	We are stressing the idea that a combination of learning CAD and developing a design- work will hardly lead to success. It is first important to learn the principle handling of CAD - only then a reasonable application can work out. Our pupils have the chance of comparing, Iearning and working on several different CAD-systems with different philosophies and purposes, so the interested students have the opportunity to choose a tool that fits their working-habits and their designing-methods. Out of an overall number of 200 students of architecture each semester about 150 are willing to participate in the CAD- curriculum. 100 will be left after the low-level introductions and exercises, done with the standard: AutoCAD - these students than have a basic idea of construction with computers. Those students who are going into details are deepening there skills to an extent where any experiment is feasible. It is hard work to get to this perfection.

title	Computer Integrated Building-up Planning (CIBP)
source	CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 259-265
summary	Building-up planning holds a prominent position within the planning- and realization process due to its closeness to the constructional-spatial translation. Based on spatial analysis, spatial characteristics and the elaboration of marginal conditions of spatial development within the framework of building-up planning, building volumina, building density, manner of building-up and storeyheights amongst others are to be defined and analyzed as to their spatial impact prior to their realization. The present project has presented possibilities for improvement of planning quality as well as of optimizing clearness and comprehension of the legally binding marginal conditions of building-up planning. Based on the wording of the Austrian Law governing Area Planning building-up planning constitutes an integral part of Urban and Regional planning. Building-up planning is the planning instrument considered right next to putting into reality the effects of which becoming immediately visible in the constructional transfer of frame conditions of spatial development. As a legal instrument it is - due to its overpacked nature - complicated in its practical application and disposes of only a small degree of flexibility concerning its consequences. Thus, a major goal of the research project aims at the development of a building-up plan of a prohibitory - (mandatory) plan acting as an instrument for designing public space.

doi	https://doi.org/10.52842/conf.ecaade.1994.147
summary	Practically every design- and planning activity aims at its ultimate realization in the built environment. Any respective decisions are generally taken on the basis of substitutes of the original. Yet, the true spatial dimensions and proportions can be conceived on a 1:1 scale "without any mental detour". Moreover, the interaction of light, colour and material is best represented in the 1:1 model. One of the main reasons why physical 1:1 models are rarely constructed is certainly the unbalanced economic relation between expenditure and resulting use. Therefore, representation by means of less expensive virtual models has taken a preeminent position. However, a balanced combination of physical and virtual models in full-scale according to area- and problem-type, degree of details and scale is likely to become increasingly important in the future. It is not the aim of Simulation Aided Architectural Design (SAAD) and Simulation Aided City Development (SACD) to do completely away with existing working procedures and planning techniques, but to act supplements promoting the integration of traditional and new simulation techniques by an-ticipating "realities" aimed at the best-suited design of a common living space. Furthermore, the generation of visions and utopian schemes may add to an enhancement as far as spatial development and design are regarded within the issue of falsification and verification of spatial developments.

doi	https://doi.org/10.52842/conf.ecaade.2019.1.595
summary	This paper is a take on contemporary works in wood designed with parametric softwares and seen from an academic and professional point of view. The knowledge about digital wood developed through Digital Fabrication Laboratories has proved to be effective but with certain limitations when used for real constructions. In fact, translating the freedom of building temporary architectures -which is usually one of the "learn by doing" activities of design studio or workshops- into wood architecture that respect all the constraints of real construction is a challenge. This paper shows several experiences where innovative ideas developed through research have been applied to temporary pavilions and real constructions in Japan, Italy and France.

source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 837-842
summary	This paper illustrates an approach to hybrid architectural form-making. A hypothetical project - the Des Moines Art Center 3rd Addition - is employed as a design experiment. The computer is used as a form-searching medium in the form-making process. Suggesting an addition to the existing center designed by Saarinen, Pei, and Meier, the designer is confronting the problem of how to respond to the three distinct architectural styles. The proposed solution to this problem is to create a hybrid building which inherits architectural properties from those precedents. Potentials of the use of the computer for such task are discussed.

doi	https://doi.org/10.52842/conf.ecaade.2000.313
summary	Geometric regularity constitutes a basis for designers to initiate the formulation of building shapes and urban forms. For example, Le Corbusier considers the regulating line "an inevitable element of architecture" and uses it as a "means" for understanding and creating good designs. Thomas Beeby argues that the acquisition of knowledge on geometric construction plays a crucial role in the education of architecture design. This paper illustrates a computational approach to constructing the regularity of architectural geometry. The formal structure underlying a single façade and continuous façades are examined.

summary	In this paper the following geometric problem is considered. Let R1,...,Rm be rectangles on the plane with sides parallel to the coordinate axes. An algorithm is described for finding the contour of F = R1, U...U Rm, in O(m log m+p log(2m2/p)) time, where p is the number of edges in the contour. This is O(m2) in the general case, and o(m log m) when F is without holes (then p < 8m - 4); both of these performances are optimal

title	Optimization-based reconstruction of a 3D object from a single freehand line drawing
source	Computer-Aided Design, Vol. 28 (8) (1996) pp. 651-663
summary	This paper describes an optimization-based algorithm for reconstructing a 3D model from a single, inaccurate, 2D edge-vertex graph. The graph, which serves as input for the reconstruction process, is obtained froman inaccurate freehand sketch of a 3D wireframe object. Compared with traditional reconstruction methods based on line labelling, the proposed approach is more tolerant of faults in handling both inaccurate vertexpositioning and sketches with missing entities. Furthermore, the proposed reconstruction method supports a wide scope of general (manifold and non-manifold) objects containing flat and cylindrical faces. Sketchesof wireframe models usually include enough information to reconstruct the complete body. The optimization algorithm is discussed, and examples from a working implementation are given.

source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 101-104
summary	The paper explains the evaluation of an instrument, based on a GIS to asses the level of proximity of neighborhood locations to urban services and facilities. Starting from a selected set of these, circles are drawn on a city map with radii representing neighborhood access. The areas within the circles are identified as having a certain level of access. Neighborhood locations within the intersection of two or more of these circles are assigned increasing levels of access. The result is an “access map” atthe city level which represents the amount of services or “urban benefits” that a person can get from a specific neighborhood location. This map is then compared to population distribution and analyzed in terms of deficit of services and facilities.

title	Study on Zoning of Urban Morphology based on GIS
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 317-326
doi	https://doi.org/10.52842/conf.caadria.2009.317
summary	The traditional studies of urban morphology mainly focus on material aspects such as urban construction, urban environment. The writers of the paper, however, point out that the nature behind material aspects should be load capacity of urban land-use, which can be reflected through some economic and technological indexes, such as floor area ratio(FAR), building density and building height, and generally they are relative. The paper forms a new morphology zoning method after having studied the relation of the above indexes based on the digital methods of GIS. This rout of thought may have some reference value for controlling the expanse of urban land-use, optimizing the allocation of resources and urban morphology and supervising the implementation of urban planning. In the paper, the author proposed the concept of “zhubei” to describe and evaluate urban morphology. We can further analyze “zhubei” regards urban planning analysis and management, for example, the slope analysis, aspect analysis, view analysis, area and volume analysis etc. Therefore, we can describe current urban morphology and evaluate its rationality by relevant conclusions just like describing vegetation.
