title	XML-Based Interactive 3D Campus Map
doi	https://doi.org/10.52842/conf.caadria.2003.631

summary	This paper presents the development of a prototype XMLbased 3D campus map using the 3D VML library. Many universities in the U.S. use two-dimensional (2D) raster image to provide the campus map along with additional building information on their Web site. Research shows that three-dimensional (3D) expression of the 3D objects helps human beings understand the spatial relationship between the objects. Some universities use 3D campus maps to help visitors more intuitively access the building information. However, these 3D campus maps are usually created using raster images. The users cannot change the view point in the 3D campus map for better understanding of the arrangement of the campus. If the users can navigate around in the 3D campus map, they may be able to locate the building of their interest more intuitively. This paper introduces emerging Web technologies that deliver 3D vector graphics on the Web browser over the internet, and the algorithm of the prototype XML-based 3D campus map. Some advantages of using VML in delivering the interactive 3D campus map are also discussed.

title	A Site-Based Computerized Production Planning & Control Model for The Plants which Produce Prefabricated Building Components
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	The "open systems" in building prefabrication may be qualified more flexible to some extent compared to the closed ones and may use the tools and approaches used in industrial production areas for the estimation of demand and production. As for the closed systems in particular, it is not possible for these systems to apply this kind of approach. Their production must be based on absolutely assured demands and projects. Because of this, they need detailed projects and assembly schedules for produc-tion. As a result of this, their production modes can be qualified "custom-made" type and production planning functions must provide the demand values from the assembly schedules of contracted proj-ects. The problem can be solved by integrating the work schedules of the sites that are served by fac-tory. Integration of data on a computerized system will be preferable and it is possible to realize the model in two alternative ways. The first is developing a new conceptual model and convert it into a software and the second is developing an approach for customizing general purpose project planning and programming software for using them in production planning. The second solution is studied in the paper following this. The aim of this study is to develop the principals of a conceptual model for an Integrated Data Flow and Evaluation System for production planning in prefabrication and to con-vert this model into an applicable and objective computer-aided model.

title	A Methodology for Material-based Computational Design Supported by Mobile Augmented Reality Application
source	Hybrid Spaces of the Metaverse - Architecture in the Age of the Metaverse: Opportunities and Potentials [10th ASCAAD Conference Proceedings] Debbieh (Lebanon) [Virtual Conference] 12-13 October 2022, pp. 301-312
summary	To represent design, both physical and digital models are utilized in the process. However, they usually don't function in unison. In order to synchronize these two types of models, the changes made in one model are generally translated into the other one later. This study intends to provide a conceptual framework for a simultaneous and synchronized model for the use of material, structure, and performance in the preliminary design stage. The methodology of the study includes evaluating material attributes, structural systems, and building performance of a physical model in the digital environment by using a Mobile Augmented Reality (MAR) interface. Because the cameras in MAR environment are mobile, the range of views can be expanded, and/or designs can be superimposed on user interfaces virtually. Thus, object interaction and navigation are all made possible. By offering a comprehensive, synchronized, and interactive design environment, where material, structure, and performance factors are incorporated both in physical and digital models, the suggested methodology will potentially aid users' decision-making process.

title	Desk Mate: A Collaborative Drawing Platform
doi	https://doi.org/10.52842/conf.caadria.2023.2.521
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. 521–530
summary	Machine Learning (ML) in architecture is an emerging field with myriad potentials to impact the design process. Despite its many possibilities, ML is typically employed when the design problem is sufficiently defined, and further, is only integrated within software environments. Desk Mate is collaborative drawing machine that can be used early in the design process by coupling tangible tools like pens and trace paper with ML driven feedback and generation. Embedding physical tools that are familiar and intuitive with digital intelligence offers designers new ways of engaging with ML algorithms interactively, potentially changing the way the architectural industry approaches design problems. Desk Mate chains together image retrieval methods from machine vision with generative ML models like variational autoencoders (VAE) and generative adversarial networks (GANS) to react to design sketches as they are drawn. This pipeline allows Desk Mate to iterate through designs with the designer. Thus, Desk Mate demonstrates an interactive platform that collocates designer and machine as creative agents, facilitating drawing with ML driven feedback, potentially accelerating design iteration in the early stages of ideation.

title	Sketching interpretation in novice and expert designers
source	Gero, J.S. and Tversky, B. (Eds.), Visual and Spatial Reasoning in Design , Key Centre of Design Computing and Cognition, University of Sydney, Sydney, Australia, pp. 209-220
summary	This paper focuses on the differences in visual reasoning between a novice and an expert architectural designer during the conceptual design process. The cognitive actions of each designer while sketching were categorized into four main groups (each consisting of a number of sub-groups): physical, perceptual, functional, and conceptual. Based on this analysis, we found that the expert differs markedly from the novice in productivity in terms of the number of sketches and the number of alternative ideas. We focused on the differences between them in terms of the frequencies of cognitive actions, with the hypothesis that the difference in productivity could be attributed to the differences in some or all types of cognitive actions. Differences between the expert and the novice were found for revising features (in the subcategory of drawing actions in the physical action category), for paying attention to the relations of depicted elements (perceptual category) and for the rates of new and revisited functions (functional category). These results are discussed in terms of the types of visual reasoning processes that could be involved in expert design and the possible implications of these results if they can be demonstrated to be characteristic of expert designers generally.

title	Transparency for Computer Synthesized Images
source	SIGGRAPH '79 Conference Proceedings. August, 1979. vol. 13 ; no. 2: pp. 158-164 : ill. (some col.). includes bibliography
summary	Simple transparency algorithms which assume a linear transparency over an entire surface are the type most often employed to produce computer synthesized images of transparent objects with curved surfaces. Although most of the images created with these algorithms do give the impression of transparency, they usually do not look realistic. One of the most serious problems is that the intensity of the light that is transmitted through the objects is generally not proportional to the amount of material through which it must pass. Another problem is that the image seen behind the objects is not distorted as would naturally occur when the light is refracted as it passes through a material of different density. Use of a non-linear transparency algorithm can provide a great improvement in the realism of an image at a small additional cost. Making the transparency proportional to the normal to the surface causes it to decrease towards the edges of the surface where the path of the light through the object is longer. The exact simulation of refraction, however, requires that each sight ray be individually traced from the observer, through the picture plane and through each transparent object until an opaque surface is intersected. Since the direction of the ray would change as each material of differing optical density was entered, the hidden surface calculations required would be very time consuming. However, if a few assumptions are made about the geometry of each object and about the conditions under which they are viewed, a much simpler algorithm can be used to approximate the refractive effect. This method proceeds in a back-to-front order, mapping the current background image onto the next surface, until all surfaces have been considered

summary	Many schools of architecture have been attempting to integrate computer applications into their curriculum. This paper will briefly discuss computer-aided design courses that are offered at USC, courses that are similar to those being offered at many universities, and then describe three exceptional cases where the student initiated the use of the computer in a way that was unexpected and different from the methods being taught. A result of conscious deliberation by the student, this experimentation resulted in unexpected discoveries by the instructors of the course. It is this digital serendipity that we wish to explore and discuss. Only occasionally do we hear much about these explorations in formal proceedings and conferences, but they are some of the most intriguing and interesting aspects of computer integration in design.

title	Performance comparison analysis of 3D reconstruction modeling software in construction site visualization and mapping
source	International Journal of Architectural Computing 2022, Vol. 20 - no. 2, pp. 453–475
summary	Unmanned aerial vehicle (UAV) technology has overcome the limitations of conventional construction management methods using advanced and automated visualization and 3D reconstruction modeling techniques. Although the mapping techniques and reconstruction modeling software can generate real-time and high-resolution descriptive textural, physical, and spatial data, they may fail to develop an accurate and complete 3D model of the construction site. To generate a quality 3D reconstruction model, the construction manager must optimize the trade-offs among three major software-selection factors: functionalities, technical capabilities, and the system hardware specifications. These factors directly affect the robust 3D reconstruction model of the construction site and objects. Accordingly, the purpose of this research was to apply nine well-established 3D reconstruction modeling software tools (DroneDeploy, COLMAP, 3DF+Zephyr, Autodesk Recap, LiMapper, PhotoModeler, 3D Survey, AgiSoft Photoscan, and Pix4D Mapper) and compare their performances and reliabilities in generating complete 3D models. The research was conducted in an eco-home building at the University of Technology, Malaysia. A series of regression analyses were conducted to compare the performances of the selected 3D reconstruction modeling software in alignment and registration, distance computing, geometric measurement, and plugin execution. Regression analysis determined that among the software programs, LiMapper had the strongest positive linear correlation with the ground truth model. Furthermore, the correlation analysis showed a statistically significant p-value for all software, except for 3D Survey. In addition, the research found that Autodesk Recap generated the most-robust and highest-quality dense point clouds. DroneDeploy can create an accurate point cloud and triangulation without using many points as required by COLMAP and LiMapper. It was concluded that most of the software is robustly, positively, and linearly correlated with the corresponding ground truth model. In the future, other factors involving software selection should be studied, such as vendor-related, user-related, and automation factors.

summary	Computational design and digital fabrication have expanded the use of digital manufacturing machineries for the realization of architecture, yet they have their own limitations of material use. These limitations caused some materials like cement, plaster and clay become marginal in this new digital context, despite their vast use in the building industry. In this context, this paper will present a research, focusing on the use of concrete through the development of a custom-designed device, which is an adjustable digital mould. This digital mould has been designed specifically for a project called Procrystalline Wall and has been 'adapted' to the conditions of its agenda in terms of size, shape, typology, and even technical matters. However, this adaptability means that the device is not aimed to work for any other project and remain exclusive to this particular design only. This paper will further discuss the validity and obstacles of the presented method in a more global context.

summary	Developing digital tools has enabled the integration of fabrication constraints into design processes. Meanwhile, they have allowed more collaboration across geographic boundaries. This paper investigates the integration of physical and environmental constraints with diverse human user intentions. More specifically, an adaptive and collaborative design-to-construction workflow was developed and tested to facilitate synchronous work across two different robotic environments. In this study, users in Japan and Germany collaborated to assemble complex timber structures using locally calibrated tools and real-time feedback. Their robots were controlled via a shared digital system and communicated continuously to adapt to subtle differences in their setups, such as slight tool variations and workbench dimensions. By integrating cloud-based data sharing and real-time adjustments to the state of the shared digital and physical model, the study participants designed and built two nearly identical structures with high precision in two locations. With an emphasis on physical feedback, this shows the potential of integrated design and fabrication in remote collaborations.

summary	Houses are essentially one-of-a-kind products that should reflect individualized differences of inhabitants who live in them. Homebuyers and homebuilders alike are thus captivated by the difficulties of housing customization. Achieving customer satisfaction depends on the flexibility of customized solutions, though the challenge of flexibility lies in the complexity of design validation. Constraints may be seen as design limitations, but they could provide for the efficiency of design validation. This paper addresses the complexities in the adoption of mass customization in the housing industry, and presents a dimensional customization system which would effectively use building information modeling (BIM) software, parametric design, and automatic verification of dimensional constraints to merge customization and validation.

summary	Fostering an inclusive and democratic decision-making process is essential to developing liveable, socially acceptable, and environmentally conscious built environments. For informed decision-making in this process, stakeholders’ understanding of design data plays an important role, as do the other disciplines embracing data-informed discourses and cultures. However, more work is needed to develop novel platforms for supporting data-informed decision-making in built environment design. Public engagement and town hall meetings are common methods to engage the public. They are often restricted by time, space, and participation scope. The online tools for data democratization in various fields offer opportunities to promote a democratic discourse; although their purpose varies, their characteristics can guide the search for novel approaches adopting a new class of tools for building design. We propose a conceptual framework for evaluating and designing tools supporting data-informed [built environment] design democratization through inclusive discourses called Di-Dem. As a contribution, we demonstrated the application of the framework in evaluating ten platforms offered for similar purposes.

title	A responsive morphing media skin
doi	https://doi.org/10.52842/conf.caadria.2012.517
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 517–526
summary	Existing media façades do not function as fenestration devices. They have been used mainly for visual communication and aesthetic purposes. This paper introduces a responsive morphing skin that can act as an active fenestration device as well as a media skin. We investigate new possibilities of using form-changing materials in designing responsive morphing skins that respond to environmental conditions and act as a communicative display. The design experiment that embodied this investigation, namely Blind, serves as a new layer of analogue media brise-soleil for existing space. It communicates the relationships between interior and exterior spaces visually and projects mutable imageries to the surrounding environment through sunlight. The design process of Blind simulates the responsive behaviour of the intended architectural skin by integrating physical computing and parametric design tools. This process includes the integration of soft apertures and architectural morphing skin to introduce a novel design method that enables an architectural skin to be a means of communication and fenestration. It responds to changing stimuli and intends to improve the spatial quality of existing environments through two types of transformations: morphological and patterned.

title	Designing a Responsive Material System with Physical Computing
doi	https://doi.org/10.52842/conf.caadria.2014.097
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 97–106
summary	This paper focuses on an investigation to explore architectural design potentials with a responsive material system and physical computing. Contemporary architects and designers are seeking to integrate physical computing in responsive architectural designs; however, they have largely borrowed from engineering technology’s mechanical devices and components. There is the opportunity to investigate an unexplored design approach to exploit the responsive capacity of material properties as alternatives to the current focus on mechanical components and discrete sensing devices. This opportunity creates a different design paradigm for responsive architecture that investigates the potential to integrate physical computing with responsive materials as one integrated material system. Instead of adopting highly intricate and expensive materials, this approach is explored through accessible and off-the-shelf materials to form a responsive material system, called Lumina. Lumina is implemented as an architectural installation called Cloud that serves as a morphing architectural skin. Cloud is a proof of concept to embody a responsive material system with physical computing to create a reciprocal and luminous architectural intervention for a selected dark corridor. It represents a different design paradigm for responsive architecture through alternative exploitation of contemporary materials and parametric design tools.

summary	There is a close relation between building design and fabrication. However still it is mostly a sequential process where the fabrication with its geometric chances and limitations is only to a small extend taken into account in early design phases. In this paper we describe a protoype form work project, realized out of styrofoam cut out with a CNC hot wire-cutting system and coated with the Claraporon coating system. Due to the linear nature of hot wire cutting the surfaces that can be created are ruled surfaces. They are discussed in a more general way as well as first exercises with ruled surfaces in teaching.

title	Design Exploration through Bidirectional Modeling of Constraints
source	Massachusetts Institute of Technology
summary	Today digital models for design exploration are not used to their full potential. The research efforts in the past decades have placed geometric design representations firmly at the center of digital design environments. In this thesis it is argued that models for design exploration that bridge different representation aid in the discovery of novel designs. Replacing commonly used analytical, uni-directional models for linking representations, with bidirectional ones, further supports design exploration. The key benefit of bidirectional models is the ability to swap the role of driver and driven in the exploration. The thesis developed around a set of design experiments that tested the integration of bidirectional computational models in domain specific designs. From the experiments three main exploration types emerged. They are: branching explorations for establishing constraints for an undefined design problem; illustrated in the design of a concept car. Circular explorations for the refinement of constraint relationships; illustrated in the design of a chair. Parallel explorations for exercising well-understood constraints; illustrated in a form finding model in architecture. A key contribution of the thesis is the novel use of constraint diagrams developed to construct design explorers for the experiments. The diagrams show the importance of translations between design representations in establishing design drivers from the set of constraints. The incomplete mapping of design features across different representations requires the redescription of the design for each translation. This redescription is a key aspect of exploration and supports design innovation. Finally, this thesis argues that the development of design specific design explorers favors a shift in software design away from monolithic, integrated software environments and towards open software platforms that support user development.

title	An Urban Building Energy Simulation Method Integrating Parametric BIM and Machine Learning
doi	https://doi.org/10.52842/conf.caadria.2023.1.665
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. 665–674
summary	This research investigates a method of urban building energy simulation (UBES) by integrating Building Information Modeling (BIM), building simulation, and algorithm-based prediction to forecast the impact of surrounding conditions. In the urban context, building energy performances are determined not only by the individual building design but also by the building's surrounding context. Many energy performances are sensitive to outdoor and surrounding building conditions, such as neighbouring building volumes, heights, and spaces between buildings. However, such surrounding conditions were overlooked because they can exponentially increase the complexity of urban modeling and simulation. In that regard, the research sought to investigate a novel framework to take advantage of accurate performance simulations and algorithm-based fast predictions. This paper presents our UBES method implemented from three research phases: (i) building a parametric urban model in BIM to provide simulation inputs, (ii) creating a parametric simulation interface to produce training and validation data, and (iii) creating a prediction interface using a Support Vector Machine (SVR) algorithm. Lastly, the paper elaborates on the findings from the prediction results.

summary	Venation structures in leaves fulfil both circulatory as well as structural functions within the organism they belong to. A possible digital simulation algorithm for the growth of venation patterns based on the leaf surface has been described by the Department of Computer Science at the University of Calgary.Cell-based growth algorithms to generate surface meshes have been developed by biological and medical scientists as well as artists, in order to gain an understanding of developmental biology or to generate artistic form. This paper suggests the combination of the two algorithms in order to generate the morphologies of leaves and other structures while at the same time generating the corresponding venation system.The resulting algorithm develops large non-manifold mesh structures based on local rules of division of the individual cells. The venation system develops in parallel based on the flow of the plant hormone auxin from those cells towards the start point or petiole of the leaf. Different local behaviours of the cells towards their adjacent neighbours, towards their rules of division and towards the rules of developing veins have been investigated. The eventual aim of the algorithms is their application as tools to develop architectural and structural morphologies.
