title	Models of light reflection for computer synthesised pictures
source	Computer Graphics, 11 2, 192-198
summary	Bui-Tuong Phong published his illumination model in 1973, in the paper titled "Illumination for Computer-Generated Images". Phong's model is a local illumination model, which means only direct reflections are taken into account. Light that bounces off more than one surface before reaching the eye is not accounted for. While this may not be very realistic, it allows the lighting to be computed efficiently. To properly handle indirect lighting, a global illumination method such as radiosity is required, which is much more expensive. In addition to Phong's basic lighting equation, we will look at a variation invented by Jim Blinn. Blinn changed the way specular is calculated, making the computations slightly cheaper. Blinn published his approach in his paper "Models of Light Reflection for Computer Synthesised Pictures" in 1977.

title	Simulation of Wrinkled Surfaces
source	Computer Graphics 12 3. 286-292
summary	Computer generated shaded images have reached an impressive degree of realism with the current state of the art. They are not so realistic, however, that they would fool many people into believing they are real. One problem is that the surfaces tend to look artificial due to their extreme smoothness. What is needed is a means of simulating the surface irregularities that are on real surfaces. In 1973 Ed Catmull introduced the idea of using the parameter values of parametrically defined surfaces to index into a texture definition function which scales the intensity of the reflected light. By tying the texture pattern to the parameter values, the texture is guaranteed to rotate and move with the object. This is good for showing patterns painted on the surface, but attempts to simulate rough surfaces in this way are unconvincing. This paper presents a method of using a texturing function to perform a small perturbation on the direction of the surface normal before using it in the intensity calculations. This process yields images with realistic looking surface wrinkles without the need to model each wrinkle as a separate surface element. Several samples of images made with this technique are included.

summary	Several research projects (Gramazio et al. 2014; Willmann et al. 2015; Helm et al. 2017; Adel et al. 2018; Adel Ahmadian 2020) have investigated the use of automated assembly technologies (e.g., industrial robotic arms) for the fabrication of nonstandard timber structures. Building on these projects, we present a novel and transferable process for the robotic fabrication of bespoke timber subassemblies made of off-the-shelf standard timber elements. A nonstandard timber structure (Figure 2), consisting of four bespoke subassemblies: three vertical supports and a Zollinger (Allen 1999) roof structure, acts as the case study for the research and validates the feasibility of the proposed process.

title	From Design to the Fabrication of Shellular Funicular Structures
doi	https://doi.org/10.52842/conf.acadia.2021.328
source	ACADIA 2021: Realignments: Toward Critical Computation [Proceedings of the 41st Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 979-8-986-08056-7].

summary	Shellular Funicular Structures (SFSs) are single-layer, two-manifold structures with anticlastic curvature, designed in the context of graphic statics. They are considered as efficient structures applicable to many functions on different scales. Due to their complex geometry, design and fabrication of SFSs are quite challenging, limiting their application in large scales. Furthermore, designing these structures for a predefined boundary condition, control, and manipulation of their geometry are not easy tasks. Moreover, fabricating these geometries is mostly possible using additive manufacturing techniques, requiring a lot of supports in the printing process. Cellular funicular structures (CFSs) as strut-based spatial structures can be easily designed and manipulated in the context of graphic statics. This paper introduces a computational algorithm for translating a Cellular Funicular Structure (CFS) to a Shellular Funicular Structure (SFS). Furthermore, it explains a fabrication method to build the structure out of a flat sheet of material using the origami/ kirigami technique as an ideal choice because of its accessibility, processibility, low cost, and applicability to large scales. The paper concludes by displaying a structure that is designed and fabricated using this technique.

summary	Architectural Education faces limitations due to its tactile approach to learning in classrooms with only 2-D and 3-D tools. At a higher level, virtual reality provides a potential for delivering more information to individuals undergoing design learning. This paper investigates a hypothesis establishing grounds towards a new research in Building Information Modeling (BIM) and Virtual Reality (VR). The hypothesis is projected to determine best practices for content creation and tactile object virtual interaction, which potentially can improve learning in architectural & construction education with a less costly approach and ease of access to well-known buildings. We explored this hypothesis in a step-by-step game design demonstration in VR, by showcasing the exploration of the Farnsworth House and reproducing assemblage of the same with different game levels of difficulty which correspond with varying BIM levels of development (LODs). The game design prototype equally provides an entry way and learning style for users with or without a formal architectural or construction education seeking to understand design tectonics within diverse or cross-disciplinary study cases. This paper shows that developing geometric abstract concepts of design pedagogy, using varying LODs for game content and levels, while utilizing newly developed features such as snap-to-grid, snap-to-position and snap-to-angle to improve user engagement during assemblage may provide deeper learning objectives for architectural precedent study.

title	Computer analysis of visual perception - endoscopy without endoscope
source	Architectural and Urban Simulation Techniques in Research and Education [Proceedings of the 3rd European Architectural Endoscopy Association Conference / ISBN 90-407-1669-2]
summary	This paper presents a method of using computer animation techniques in order to solve problems of visual pollution of city environment. It is our observation that human-inducted degradation of city environmental results from well - intentioned but inappropriate preservation actions by uninformed designers and local administration. Very often, a local municipality administration permits to build bad-fitting surroundings houses. It is usually connected with lack of visual information's about housing areas of a city, its features and characteristics. The CAMUS system (Computer Aided Management of Urban Structure) is being created at the Faculty of Architecture of Bialystok Technical University. One of its integral parts is VIA - Visual Impact of Architecture. The basic element of this system is a geometrical model of the housing areas of Bialystok. This model can be enhanced using rendering packages as they create the basis to check our perception of a given area. An inspiration of this approach was the digital endoscopy presented by J. Breen and M. Stellingwerff at the 2nd EAEA Conferences in Vienna. We are presenting the possibilities of using simple computer programs for analysis of spatial model. This contribution presents those factors of computer presentation which can demonstrate that computers achieve such effects as endoscope and often their use be much more efficient and effective.

title	Parametric design and multirobotic fabrication of wood facades
doi	https://doi.org/10.52842/conf.acadia.2021.258
source	ACADIA 2021: Realignments: Toward Critical Computation [Proceedings of the 41st Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 979-8-986-08056-7]. 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. 258-269.
summary	The paper describes the findings of the applied research project by Institute Integrative Design (currently ICDP) HGK FHNW and ERNE AG Holzbau to design and manufacture prefabricated wooden façades in the collaborative design manner between architects and industry. As such, it is an attempt to respond to the current interdisciplinary split in the construction, which blocks innovation and promotes standardized inefficient building solutions. Within this project, we apply three innovations in the industrial setup that result in the integrated design-to-production process of individualized, cost-efficient and well-crafted façades. The collaborative design approach is a method in which architect, engineer and manufacturer start exchange on the early stage of the project during the collaborative design workshops. Digital design and fabrication tools enable architects to generate a large scope of façade variations within production feasibility of the manufacturer and engineers to prepare files for robotic production. Novel multi-robot fabrication processes, developed with the industrial partner, allows for complex façade assembly. This paper introduces the concept of digital craftsmanship, manifested in a mixed fabrication system, which intelligently combines automated and manual production to obtain economic feasibility and highest aesthetic quality. Finally, we describe the design and fabrication of the project demonstrator consisting of four intricate façades on a modular office building, inspired by local traditional solutions, which validate the developed methods and highlight the architectural potential of the presented approach.

title	Performative Agency of Materials: Matter agency of vernacular African pattern systems
doi	https://doi.org/10.52842/conf.caadria.2016.641
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 641-650
summary	This paper investigates an agency of materials through a design methodology that follows Martin Heidegger’s process of “Entbergen” or “unconcealing” as a non-instrumentalist understanding of tools and materials. This investigation takes place through the de- sign of a children’s theatre in South Africa where material innovation for architectural components is needed. The research studies vernacu- lar African patterns and their inherent behaviour when transferred to materials. The transference of pattern systems to architectural proto- types is discussed alongside the discussion of their technical and ar- chitectural performance criteria. Following Heidegger’s theory of “Entbergen” (“unconcealing”) the paper will demonstrate how making in this methodology becomes an “unconcealing”, which includes both digital and analogue means, linking the four causalities - causa mate- rialis, causa formalis, causa finalis, and causa efficiens – through the agency of material within an integrated process between all four caus- es. Making becomes a process in which form is generated through in- terventions within fields of forces and currents of materials, taking cause and agency into account, and standing in opposition to methods that are defined by a premeditated notion of an ideal outcome.

summary	The exploding functionality of current computer-aided engineering (CAE) systems has provided today’s users with a vast, but under-utilized collection of tools and options. For example, MicroStation, a popular CAE system sold by Intergraph, offers more than 1000 commands including 16 ways to construct a line (in different contexts) and 28 ways to manipulate elements using a “fence”. This complex array of functionalities is bewildering and hardly exploited to its full extent even by frequent, experienced users. In a recent site visit to a federal design office, we observed ten architects and three draftsmen using MicroStation.

title	Separating the Knowledge Layers: Cognitive Analysis of Search Knowledge Through Hierarchical Goal Decompositions
source	Proceedings of the ASIST'2002 (2002), 204-213
summary	Hierarchical goal decompositions have proved to be a useful method to make explicit the knowledge required by users to perform tasks in a wide range of applications such as computeraided drafting (CAD) systems. This analysis method progressively decomposes a given task starting from the task layer on the top of the decomposition, to the keystroke layer at the bottom. The analysis enables a close inspection of the knowledge required to perform the task at each layer of the decomposition. In this paper we show how the method of hierarchical goal decomposition can be used to understand more precisely the knowledge that is required to perform information search tasks. The analysis pinpoints: (1) the critical strategies in the intermediate layers of knowledge that are known by experts searchers; (2) why such knowledge is difficult to acquire by novice searchers; (3) how the analysis provides testable predictions of behavior based on the acquisition of different types of knowledge. We conclude by discussing the advantages provided by hierarchical goal decompositions, and how such an approach can lead to the design of systems and training.

title	CAD usage in an architectural office: from observations to active assistance
source	Automation in Construction 5 (3) (1996) pp. 243-255
summary	The functionality and resources provided by CAD systems have been increasing rapidly, but productivity growth expected from their use has been difficult to achieve. Although many surveys describe this productivity puzzle, few studies have been conducted on actual CAD users to understand its causes. In an effort to arrive at such an understanding, the first author visited a federal architectural office and observed CAD users in their natural setting. This paper describes preliminary results obtained from the study, which used ethnographic techniques developed by cultural anthropologists. The study revealed that users had leveled-off in their learning and experimentation and were using the CAD system in suboptimal ways. By asking why users were not using many resources available to them to improve performance, the observer uncovered issues of communication and management that needed to be addressed. Based on this understanding, the authors provide explicit recommendations to CAD users and vendors. In addition, they hypothesize that users might benefit from a system that provides active assistance, that is, intervenes spontaneously with advice, assistance, and relevant information while the user interacts with the CAD system. They conclude with some issues revealed by the study that should be considered when developing such active assistance.

summary	Current interfaces and help facilities of CAD systems are not designed to respond to a user's performance. To develop such adaptive environments, a better understanding of the indicators of CAD experience is required. This paper discusses the results of studying behavior patterns of different types and levels of CAD users for a specific drawing task. The results show that the type and experience of the CAD user has a clear correlation to the pattern of commands used, the time taken, and the quality of drawing produced. By using the experimental data to train a neural network, the paper demonstrates a connectionist approach for experience assessment. This information, it is proposed, can provide input to an adaptive interface which generates unobtrusive interception to improve the performance of a CAD user. Future experiments to explore the issues of generality and interception are presented.

summary	Positioned at the intersection of the computational modes of design and production, this research explains the principles and applications of a novel fabrication-informed geometric system called nesting. Applying the nesting fabrication method, the authors reimage the construction of complex forms by proposing geometric arrangements that lessen material waste and reduce production time, transportation cost, and storage space requirements. Through this method, appearance and performance characteristics are contingent on fabrication constraints and material behavior. In this study, the focus is on developing design rules for this method and investigating the main parameters involved in dividing the global geometry of a complex volume into stackable components when the first component in the stack gives shape to the second. The authors introduce three different strategies for nesting fabrication: 2D, 2.5D, and 3D nesting. Which of these strategies can be used depends on the geometrical needs of the design and available tools and materials. Next, by revisiting different fabrication approaches, the authors introduce readers to the possibility of large-scale objects with considerable overhangs without the need for nearly any temporary support structures. After establishing a workflow starting with the identification of geometric rules of nesting and ending with fabrication limits, this work showcases the proposed workflow through a series of case studies, demonstrating the feasibility of the suggested method and its capacity to integrate production constraints into the design process. Traversing from pragmatic to geometrical concerns, the approach discussed here offers an integrated approach supporting functional, structural, and environmental matters important when turning material, technical, assembly, and transportation systems into geometric parameters.

title	Hierarchical Decomposition of Architectural Computer Models
doi	https://doi.org/10.52842/conf.caadria.1997.197
source	CAADRIA ‘97 [Proceedings of the Second Conference on Computer Aided Architectural Design Research in Asia / ISBN 957-575-057-8] Taiwan 17-19 April 1997, pp. 197-203
summary	Architectural models can be represented in a hierarchy of complexity. Higher level or more complex architecture structures are then designed by repetitively instantiating libraries of building blocks. The advantages are that the object can be achieved in modular fashion and any modification to the definition of a building block can be easily propagated to all higher level objects using the block. Unfortunately, many existing representations of architectural models are monolithic instead of hierarchical and modular, thus, making the reuse of models very difficult and inefficient. This paper describes a research project on developing a tool to decompose a monolithic architectural model into elementary building blocks and then create a hierarchy in the model representation. The tool provides a graphical interface for the visualization of a model and a cutting plane. An associated algorithm will then automatically detach parts of the model into building blocks depending on where the user is applying the cutting plane. Studies will also be made on dividing more complex models employing spherical and NURBS surfaces.

summary	Design is a complex and time consuming process. One way to simplify the design process is to use pre-build blocks for commonly known parts instead of creating them again with CAD. To give the designer an immediate 3D view of the design, designing in virtual reality is a good choice. This paper presents a virtual reality interface tool which allows a user to assemble an architecture structure from a library of pre-built blocks. The library is a distributed client-server database.

title	Free-form thick layer object manufacturing technology for large-sized physical models
source	Automation in Construction 11 (3) (2002) pp. 335-347
summary	Large-sized free-form objects of different materials are widely used in various industrial applications. Currently, layered rapid prototyping technologies are not suitable for the fabrication of this kind of objects, due to the necessity of a large number of layers and the limitations in size. This paper reports a novel approach of layered manufacturing that is more appropriate for the fabrication of these large objects. A method of thick-layered object manufacturing is presented, which is based on a higher order approximation of the shape and application of a flexible curved cutting tool.The method allows the production of physical prototypes, which need little or no finishing. In order to meet the designer's intend, as closely as possible, some feasible system characteristics are introduced. The process is ordered in a sequential way and provides a highly automated process. A hierarchical decomposition of the CAD geometry takes place into components, segments, layers and sectors, based on morphological analysis. This method enables the manufacturing and the re-assembly of the parts to produce the physical prototypes without affecting the requested functionality. Due to the possibility of obtaining multiple solutions in the physical model, much attention must be paid to the efficiency of the process.

title	Cocoon: 3D Printed Clay Formwork for Concrete Casting

summary	Concrete, a material widely used in the construction industry today for its low cost and considerable strength as a composite building material, allows designers to work with nearly any form imaginable; if the technology to build the formwork is possible. By combining two historic and widely used materials, clay and concrete, our proposed novel process, Cocoon, integrates robotic clay three-dimensional (3D) printing as the primary formwork and incrementally casting concrete into this formwork to fabricate nonstandard concrete elements. The incremental casting and printing process anchors the concrete and clay together, creating a symbiotic and harmonious relationship. The concrete’s fluidity takes shape from the 3D printed clay formwork, allowing the clay to gain structure from the concrete as it cures. As the clay loses moisture, the formwork begins to shrink, crack, and reveal the concrete below. This self-demolding process produces easily removable formwork that can then be recycled by adding water to rehydrate the clay creating a nearly zero-waste formwork. This technique outlines multiple novel design features for complex concrete structures, including extended height limit, integrated void space design, tolerable overhang, and practical solutions for clay deformation caused by the physical stress during the casting process. The novelty of the process created by 3D printing clay formwork using an industrial robotic arm allows for rapid and scalable production of nearly zero-waste customizable formwork. More significant research implications can impact the construction industry, integrating more sustainable ways to build, enabled by digital fabrication technologies.

summary	This paper discusses recent developments on the geometric construction and fabrication techniques associated with large-scale surface disclinations. The basic concept of disclinations recognizes the role of “defects” in the composition of materials, the strategic placement of which shapes the material by inducing curvature from initially planar elements. By acknowledging the relationship between geometry and topology that governs disclination based form-finding and material prototyping, this work consciously explores its potential at the architectural scale. Basic geometric figures and their topological transformations are documented in the context of digital modeling and simulation, fabrication, and a specific material palette. Specifically, this work builds on recent efforts by focusing on three particular areas of investigation; a) enhancing the stability of surface disclinations with a synthetic fibrous layer, b) aggregation via periodic tilings, and c) harnessing snap-through buckling to increase bending stiffness in thin surfaces.
