summary	The problem of filling a given volume with a 3-dimensional structural network lattice comprising a certain number of nodes is considered. The proposed method of approach is contained within the framework of iterative physical dynamic simulation and implements a generative algorithm that features a particle-spring system. The algorithm is able to suitably arrange nodes in the space of a volumetric envelope and establish connections between them through local rules of self-organisation, thus producing efficient space frames without having prior knowledge of either geometry or topology of the network lattice.

Online and Global. 3-6 November 2021. edited by B. Bogosian, K. Dörfler, B. Farahi, J. Garcia del Castillo y López, J. Grant, V. Noel, S. Parascho, and J. Scott. 372-379.
summary	The research presented in this paper proposes a bespoke digital machine-material system for architectural assembly. The research aims to contribute to the body of work in digital material systems and single-task construction and fabrication robotics. Specifically, the system proposes a digital material system based on the icosahedral quasicrystals accompanied with a bespoke assembling robot capable of locomotion along the material as well as manipulation of discrete material units. Through a set of locomotion and pick and place routines, the robotic system is capable of construction and reconfiguration of the material system. In proposing a digital machine-material system, the presented research argues for the development of design, fabrication, and robotics strategies wherein hardware, geometry, material, and software are developed in parallel in an interdependent co-design process. Such approach of considering parameters across the spectrum of design tasks allows to develop systems that are well suited for their specified application while maintaining minimum complexity and increasing accessibility of fabrication systems.

title	Web4D: Challenges and Practices for Construction Scheduling
doi	https://doi.org/10.52842/conf.acadia.2001.132
source	Reinventing the Discourse - How Digital Tools Help Bridge and Transform Research, Education and Practice in Architecture [Proceedings of the Twenty First Annual Conference of the Association for Computer-Aided Design in Architecture / ISBN 1-880250-10-1] Buffalo (New York) 11-14 October 2001, pp. 132-141
summary	Research has demonstrated that four-dimensional computer aided design (4D CAD), in which a three-dimensional (3D) CAD model is animated through time, is useful in helping professionals understand the construction schedule. However, cumbersome processes to update a 4D CAD model, which involve changing geometry representations, changing schedules and bar charts, linking the geometry to the scheduling information, and generating animations, may discourage professionals from using 4D CAD in actual construction projects. A software prototype implementing 4D CAD in a Web environment overcomes limitations of current 4D CAD tools. This software permits editing of the construction schedule over the Internet and shows the revised construction sequence visually on a Web browser using 3D computer graphics. This software is composed of a database on a server, Active Server Pages (ASP) scripts, and a Java applet that was developed using Java 3D Application Programming Interface (API) and Java JDBC. The Java applet retrieves the 4D model at the appropriate level of completion over the Internet and allows users to navigate around the model on the Web browser. Web4D visualization software can help professionals to expedite the schedule updating process by involving designers and constructors in collaborative decision- making.

title	XML-Based Interactive 3D Campus Map
doi	https://doi.org/10.52842/conf.caadria.2003.631
source	CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 631-640
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.

source	SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 286-289
summary	Due to the lack of trained individuals in the construction industry and to its potential impact on construction planning, Building Information Modeling (BIM) has been one of the popular topics taught in academic institutions in the U.S. in recent years. Although it is necessary to master multiple BIM applications in order to fully employ BIM in construction, teaching college students all of these applications in one semester is challenging. This paper presents an industry - sponsored class project developed to help students learn the principles of BIM in a short time. It also presents the opportunities and challenges you may encounter in implementing this class project.

summary	Building Information Modeling (BIM) is an effective tool students can use to learn how building components work together to secure necessary structural stability in the course of construction. In Summer 2014, students enrolled in the BIM class at Texas A&M University created a 4-dimensional construction simulation model of the Museu de Arte de São Paulo (MASP) to understand how the entire building is sustained by two huge concrete beams connected with four external columns. For this class project, students analyzed the building system while creating a 3-dimensional model of the museum. They also came up with a construction sequence that would best maintain structural integrity of the building in the course of construction, and then produced a short animation video explaining the MASP construction process. This paper presents how the MASP project helped students learn a unique building system and its construction sequence.

title	Electroencephalogram (EEG) based Emotional Lighting Design Using Deep-Learning for a User-Centric Approach
doi	https://doi.org/10.52842/conf.caadria.2024.3.391
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. 391–400
summary	This study proposes a methodology for using artificial intelligence (AI) and biometrics in spatial design. The research mainly applies a gated recurrent unit (GRU) model, a recurrent neural network (RNN), to analyze electroencephalogram (EEG) data and dynamically adjust lighting according to the user's emotional state. This study suggests an illumination adjustment system that modifies lighting according to the user's emotional state using the proposed method. Integration of EEG data can overcome the limitations of lighting systems. It can effectively target individual emotional responses. The GRU model represents a significant improvement in lighting design by addressing both cognitive and emotional user needs. The model's effectiveness in processing real-time data and adapting through incremental learning was evaluated. The model has shown a significant impact on emotional architecture and spatial design, with a focus on individual experience.

title	Feasibility of automating military's environmental operations
source	Automation in Construction 5 (6) (1997) pp. 459-468
summary	This paper focuses on analyses of the feasibility of telerobotic and autonomous systems in hazardous environments. The hazardous environments are divided into three missions: area clearance, removal of unexploded ordnance, and hazardous waste removal. This paper identifies the factors impacting military's missions on various operating systems. Then, a decision support system based on fuzzy logic is developed for studying these factors to determine the feasibility of automating military's environmental restoration operations. The last part of the paper provides a set of recommendations for technology policy development.

title	Studying designers’ behaviour in collaborative virtual workspaces using quantitative methods
doi	https://doi.org/10.52842/conf.caadria.2010.273
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 273-282
summary	This paper presents a case study comparing the behaviour of designers in a collaborative 3D virtual environment with those in a face-to-face environment using quantitative tools to examine their design protocols. It starts with depicting a design ontology along with two methods of analysis for this investigation. The results in this case show that the 3D environment increases the designer’s Structure activities. The rate of meaningful design communication is slower than the base-line face-to-face session. This communication reflects the rate of design cognition when the design process is “close coupled”. Reviewing the design protocol suggests that the 3D design session composed of both “loosely coupled” and “close coupled” periods. This is consistent with other studies that 3D collaborative tools may encourage “loosely coupled” design process.

summary	In 2018 I was invited to visit the archipelago of Kiribati, located in the Pacific Ocean around 1000 miles from Hawaii. A big ocean state, Kiribati holds a land mass of around 315 sq. miles and an oceanic economic zone of 1,328,890 sq. mi. Tarawa, the most inhabited of the islands peaks at around 3 m above sea level. I went to Kiribati in part to meet with Dr Teweiariki Teaero, a renowned scholar, poet and educator who had directed the Oceania Center at the University of the South Pacific in Fiji for many years before returning to his homeland where at the time he had been planning on running for government. Teweiariki spoke with me at length about the status of Kiribati as one of the already most critically affected frontline nations. I asked him what was a lesson for non-Pacific Islanders to learn about understanding everyday life there. He said to me “Two ears, one mouth, don’t talk too much. Learn to listen more. Not only to hear, but to be able to develop another thing and that is to be able to interpret. These things are different, they occur at different levels. The hearing and the interpretation of the sound…it’s very much part of our world” (Teaero 2018).

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	An Automatic Algorithm Designer : An Initial Implementation
source	Design Research Center, CMU, May, 1983. 10 p. includes bibliography
summary	This paper outlines a specification for an algorithm-design system (based on previous work involving protocol analysis) and describes an implementation of the specification that is a combination frame and production system. In the implementation, design occurs in two problem spaces: one about algorithms and one about the task domain. The partially worked out algorithms are represented as configurations of data-flow components. A small number of general purpose operators construct and modify the representations. These operators are adapted to different situations by instantiation and means-ends analysis rules. The data-flow space also includes symbolic and test-case execution rules that drive the component-refinement process by exposing both problems and opportunities. A domain space about geometric images supports test-case execution, domain-specific problem solving, recognition and discovery

title	A Knowledge-Based Approach to Using Efficiency Estimation in Program Synthesis
source	1980? pp. 457-462. includes bibliography
summary	This paper describes a system for using efficiency knowledge in program synthesis. The system, called LIBRA, uses a combination of knowledge-based rules and algebraic cost estimates to compare potential program implementations. Efficiency knowledge is used to control the selection of algorithm and data structure implementations and the application of optimizing transformations. Prototypes of programming constructs and of cost estimation techniques are used to simplify the efficiency analysis process and to assist in the acquisition of efficiency knowledge associated with new coding knowledge. LIBRA has been used to guide the selection of implementations for several programs that classify, retrieve information, sort, and generate prime numbers

title	Gestural Design: Hand Tracking for Digital Drawing
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. 30-42
summary	Computational design is increasingly interested in the active feedback between the user/designer and the digital space. Often, our initial instinct as designers comes from a gesture, a movement of the hands that gets translated into sketches and 3D models via the tools available to us. While the physical realm allows for muscle memory, tactile feedback, and creative output via movement, digital design often negates the body of the designer as it sequesters us into a screen-mouse-hand relationship. Moreover, current CAD software tools often reinforce this standardization, further limiting the potential of physical bodily gestures as a vehicle for architectural form-making. Seeking new opportunities for a gestural interface, this research explores how Machine Learning and parametric design tools can be used to translate active movements and gestural actions into rich and complex digital models without the need of specialized equipment. In this paper, we present an open-source and economically accessible methodology for designers to translate hand movements into the digital world, implementing the MediaPipe Hands tracking library. In developing this workflow, this research explores opportunities to create more direct, vital links between expressive gesture and architectural form, with an emphasis on creating platforms that are accessible not only to design experts, but also the broader public.

title	Lightscape - an exploration in interactive lighting
source	ETH postgraduate studies final thesis, Zurich
summary	The aim was to provide a theoretical approach to the lighting project undertaken for the xCube group work. The nds2004 students had decided to build an interactive, computeroptimised structure as their final project, where lights, sensors and textured surfaces were to create an interactive experience for the visitor. For various reasons the interactive aspect was abandoned. The idea to work on a light(-ing) object came up when I discovered a little device called the Barionet™. This device allows you to control an on/off switch remotely, through a web interface or through programming. That was it! The ip_lamp (…its first name): a small object that has its own IP address, and therefore can be accessed via the internet. Turn it on or off… This evolved into the _lightscape where 2 interacting lights send each other data about the other (distance from a wall or number of people for example). The atmosphere of a room becomes dependant of what is going on in another… This work is also an attempt to develop a pluridisciplinary approach to an architectural project by making use of the many tools available to the postgraduate students: programming a simulation in Flash, experimenting with different hardware interfaces or rapidly manufacturing a light box on the 3-axis mill. A cross-over project in a (modest) way.

source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 336-340
summary	The landscape design studio proposes to research synergies between teaching landscape architecture and using computer numerically controlled (CNC) machines as prototyping tools for students. The focus of the course is not to be proficient in CAAD-CAM technologies but to familiarize architecture students with landscape design and the problematic of large-scale topographical interventions and use these tools as verification instruments. Many prototyping tools are available to the students at the school and are easily accessible: a 3-axis mill, laser cutter, flatbed cutter and a 3D printer. Of all the CNC machines, the 3-axis mill allows for the best translation between idea and model in landscape modeling. Of interest to us is the continuous and more fluid exchange between paper/idea and a physical three-dimensional output, the ability to be able to re-shape continuously the model. The result is a series of models or evolutions, documenting the project idea as it has evolved from the initial concept to the final project.

title	Parallel Processing Techniques for Hidden Surface Removal
source	SIGGRAPH '79 Conference Proceedings. 1979. vol. 13 ; no. 2: pp. 300-307 : ill. includes bibliography
summary	Previous work in the hidden-surface problem has revealed two key concepts. First, the removal of non-visible surfaces is essentially a sorting problem. Second, some form of coherence is essential for the efficient solution of this problem. In order to provide real-time simulations, it is not only the amount of sorting which must be reduced, but the total time required for computation. One potentially economic strategy to attain this goal is the use of parallel processor systems. This approach implies that the computational time will no longer be dependent on the total amount of sorting, but more on the appropriate division of responsibility. This paper investigates two existing algorithmic approaches to the hidden-surface problem with a view towards their applicability to implementation on a parallel machine organization. In particular, the statistical results of a parallel processor implementation indicate the difficulties stemming from a loss of coherence and imply potentially important design criteria for a parallel configuration
