title	AI Style Recognition Technological Artifact on Smart Campus UEL: Design of the Evaluation Photo-taking-impairment Effect on Architectural Heritage
source	García Amen, F, Goni Fitipaldo, A L and Armagno Gentile, Á (eds.), Accelerated Landscapes - Proceedings of the XXVII International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2023), Punta del Este, Maldonado, Uruguay, 29 November - 1 December 2023, pp. 227–238
summary	This article aims to understand the critical points in the experiments of the photo-taking-impairment effect, normally researched in the act of photographing, with the use of an artifact in recognition of styles and elements in AI. For the development of the experiment, a heritage route was simulated in the UEL Smart Campus, such as Living Lab, with three wooden houses from the 1940s, and an AI application for cell phones developed in Android Studio, with models trained in Google's Teachable Machine cloud. The experiment was carried out in a pre-test with three different designs. A strong attentional disengagement was pointed out with the concern to apply more volitional experiment designs and with less conceptual codification.

title	Reconsidering the Construction of Complex Architectural Shapes: On the practical significance of Orthogonal Circle Packings in the creation of Architectural Freeform Structures
doi	https://doi.org/10.52842/conf.ecaade.2023.1.357
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 1, Graz, 20-22 September 2023, pp. 357–366
summary	Key issues to provide economically viable solutions in the creation of doubly curved architectural structures lie in reducing the complexity of supporting and connecting elements, the repetition of costly parts, and the proper rationalization of the building skin. This can, next to post-rationalization techniques, be achieved by applying constrained design approaches where analytical findings are understood in advance and considered throughout the whole planning process. Therefore, we address the design and construction of architectural freeform structures which are derived from orthogonal circle packings. Applying conformal transformations on such configurations turn out to provide a promising base regarding further specifications in simplified fabrication, materialization, and assembly of doubly curved structures. This approach, so far intensely examined by the fields of discrete differential geometry, is here investigated by a research team from the field of architectural sciences. We introduce a computational setup, starting with an orthogonal circle packing in the Complex plane. By combining particular conformal mappings, we obtain a rich variety of conformally discretized surfaces of distinct type. While performing the abovementioned transformations, valuable geometric conditions allowing the usage of simplified and repetitive building components are preserved. The setup provides an intuitive, easily accessible digital workflow from global surface construction and preliminary geometric model representation, yielding a guiding framework purposing the construction of individual building components. We introduce several shape explorations from this setup, give insights to materialization and construction techniques and synchronously discuss their particularities considering both geometric, architectural as well as structural qualities.

title	Improved Computational Methods for Ray Tracing
source	ACM Trans. on Graphics, vol. 3, no. 1, pp. 52-69, Jan. 1984
summary	This paper describes algorithmic procedures that have been implemented to reduce the computational expense of producing ray-traced images. The selection of bounding volumes is examined to reduce the computational cost of the ray-intersection test. The use of object coherence, which relies on a hierarchical description of the environment, is then presented. Finally, since the building of the ray-intersection trees is such a large portion of the computation, a method using image coherence is described. This visible-surface preprocessing method, which is dependent upon the creation of an "item buffer," takes advantage of a priori image information. Examples that indicate the efficiency of these techniques for a variety of representative environments are presented.

title	Variational surface modeling
source	Computer Graphics, 26, Proceedings, SIGGRAPH 92
summary	We present a newapproach to interactivemodeling of freeform surfaces. Instead of a fixed mesh of control points, the model presented to the user is that of an infinitely malleable surface, with no fixed controls. The user is free to apply control points and curves which are then available as handles for direct manipulation. The complexity of the surface's shape may be increased by adding more control points and curves, without apparent limit. Within the constraints imposed by the controls, the shape of the surface is fully determined by one or more simple criteria, such as smoothness. Our method for solving the resulting constrained variational optimization problems rests on a surface representation scheme allowing nonuniform subdivision of B-spline surfaces. Automatic subdivision is used to ensure that constraints are met, and to enforce error bounds. Efficient numerical solutions are obtained by exploiting linearities in the problem formulation and the representation.

title	Free-Form Shape Design Using Triangulated Surfaces
source	Computer Graphics, no. 28, pp. 247-256
summary	We present an approach to modeling with truly mutable yet completely controllable free-form surfaces of arbitrary topology. Surfaces may be pinned down at points and along curves, cut up and smoothly welded back together, and faired and reshaped in the large. This style of control is formulated as a constrained shape optimization, with minimization of squared principal curvatures yielding graceful shapes that are free of the parameterization worries accompanying many patch-based approaches. Triangulated point sets are used to approximate these smooth variational surfaces, bridging the gap between patch-based and particle-based representations. Automatic refinement, mesh smoothing, and re-triangulation maintain a good computational mesh as the surface shape evolves, and give sample points and surface features much of the freedom to slide around in the surface that oriented particles enjoy. The resulting surface triangulations are constructed and maintained in real time.

source	University of Washington, Design Machine Group
summary	Espresso blocks apply the emerging technology of modular robotics to architectural applications. Espresso blocks are delivered to a site on a pallet and then assemble themselves into one of several pre-configured structures. Using a remote control, the occupant can cycle between different structures throughout the day to accommodate different activities such as an espresso stand during the day, a dining room in the evening, and a bedroom at night. The occupant can also rearrange individual blocks with their remote control to create new configurations, save them to their remote, and even trade designs with others.

title	Exploring the Development of the Independent, Electronic, Scholarly Journal
source	University of Sheffield, Department of Information Studies
summary	This dissertation sets out to examine the extent of independent, electronic scholarly journals, that is, those that are available through the Internet, usually the World Wide Web, free of charge to the reader, and publish academic articles, usually peer reviewed. A list of journals was drawn up using the NewJour archive of journal announcements, supplemented by the World Wide Web Virtual Library and Glasgow University library catalogue. The 387 journals that were found were then categorised in the following categories: Title, URL, originating country, whether it was peer reviewed, organisation or person responsible, broad subject, narrow subject, format, language, whether there was a print version, year of first issue, year of latest issue and number of issues and articles per year. An e-mail survey was also carried out of the 84 electronic journals that had some way of determining their readership, either by having voluntary or compulsory registration, or sending e-mail updates to subscribers. The survey asked for the number of subscribers to each journal, and also the number of hits the Web site received each month It was found that most of the journals were following one of three strategies: () a Niche Market strategy - focusing a highly specialised journal to a small audience. () a Vanity Publishing strategy - producing journals in a mainstream area, with no external funding.(*) a Commercial strategy - producing journals in a mainstream area, with attempts made to gain external funding through sponsorship and advertising. It was concluded that unless the current market for electronic journals changed in some way, either by journal budgets devolving to academic departments, or some collaborative action between universities, that the future for electronic journals was as part of "one-stop shops" for particular subjects, with a mixture of free and paid for journals (or article servers), together with other related services, controlled by commercial outfits.

title	Beauty is in the Eye of the Beholder - Improving the Human-Computer Interface within VRAD by the active and two-way employment of our visual senses

summary	Whether it is via traditional methods with pen and paper or contemporary techniques such as 3D digital modelling and VR drawing, the eye typically plays a mostly passive or consuming role within the design process. By incorporating eye-tracking deeper within these methods, we can begin to discern this technologys possibilities as a method that encompasses the visual experience as an active input. Our research, however, developed the Eye-Tracking Voxel Environment Sculptor (EVES) that incorporates eye-tracking as there design actor. Through EVES we can extend eye-tracking as an active design medium. The eye-tracking data garnered from the designer within EVES is directly utilised as an input within a modelling environment to manipulate and sculpt voxels. In addition to modelling input, eye-tracking is also explored in its usability in the Virtual Reality User Interface. Eye-tracking is implemented within EVES to this extent to test the limits and possibilities of eye-tracking and the Human-Computer Interface within the realm of Virtual Reality Aided Design.

summary	Art and architectural history education has long relied on photographic imagery. The geography of architectural history often demands an analog representation for the built form and photographic recordings have long been the widely adopted standard. In many cases, specific buildings have been taught for generations based on a handful of historical exposures. The impact of this precedent is an imperfect and highly privileged conception of architectural forms. Students learn only of a particular viewpoint of any given building, rather than understanding the building as a whole. Augmenting the tradition of select and static imagery in the classroom with new technologies can create a more comprehensive understanding of architectural precedents. This paper discusses an experiment conducted in Spring 2017 in presenting an architectural case study to a history class using a Virtual Reality 3D experience in comparison to a set of canonical photographs.

title	Prototyping a Temporospatial Simulation Framework:Case of an Ottoman Insane Asylum
doi	https://doi.org/10.52842/conf.ecaade.2016.2.485

summary	Effectively communicating the history of a complex building site using only conventional presentation techniques can be limiting. It is a challenge to present temporal changes in the site simultaneously within a spatial framework. Whereas 2D drawings typically used in architectural historical scholarship are many times cleaned abstractions, 3D models might create an illusion of "recreated reality." Both representation types distance the reader from the primary sources rather than being a mechanism to bring the reader closer to the sources. This paper reports on an interactive simulation of a fin-de-siecle Ottoman insane asylum in Istanbul. Our response to these challenges incorporates to the simulation both the temporal aspect (spanning the life of the asylum and the daily life within) and primary documents by using temporally aware 3D models and keyed descriptive markers for building programming.

title	A Virtual Reality Window View Evaluation Tool for Shading Devices and Exterior Landscape Design
doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_14
source	Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
summary	The window view is an important part of the daylighting design. The current window view analysis based on daylighting metrics does not respond well to user preferences. This study uses an office with a courtyard in Berkeley, CA, USA, as a case study to create a virtual reality-based window view evaluation tool and workflow to analyze the impact of different types of shading devices and different levels of exterior landscapes on user perception. This tool combines quantitative data based on daylighting metrics and users’ subjective and physical responses with qualitative analysis based on user feedback and preferences. A two-way ANOVA was conducted in the study to demonstrate that the independent and interactive impacts of shading devices and exterior landscapes on user perception and satisfaction. The results show that users prefer shading types that block less of window views even though they may cause a higher probability of glare. Besides, advanced landscapes tend to enhance user satisfaction with shading devices. This new window evaluation method will help architects make more comprehensive decisions in shading device type selection and exterior landscape design.

source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary	Phase(x) was a successful teaching experiment we made in our entry level CAAD course in the Wintersemester 1996/97. The course was entirely organized by means of a central database that managed all the students' works through different learning phases. This setup allowed that the results of one phase and one author be taken as the starting point for the work in the next phase by a different author. As students could choose which model they wanted to work with, the whole of Phase(x) could be viewed as an organism where, as in a genetic system, only the "fittest" works survived. While some discussion of the technical set-up is necessary as a background, the main topics addressed in this paper will be the structuring in phases of the course, the experiences we had with collective authorship, and the observations we made about the memes hat developed and spread in the students' works. Finally we'll draw some conclusions in how far Phase(x) is relevant also in a larger context, that is not limited to teaching CAAD.

title	The Inventor Mentor: programming Object-oriented 3D graphics with Open Inventor
source	Release 2 Addison Wesley
summary	The Inventor Mentor introduces graphics programmers and application developers to Open Inventor, an object-oriented 3D toolkit. Open Inventor is a library of objects and methods used for interactive 3D graphics. Although it is written in C++, Open Inventor also includes C bindings. For the sake of brevity, the examples included in this book are in C++. All C++ examples, as well as equivalent examples written in C, are available on-line. If you are new to the C++ language, see Appendix A, "An Introduction to Object-Oriented Programming for C Programmers," to help you understand the references to classes, subclasses, and other object-oriented concepts used throughout this book. If you are using the C application programming interface, also see Appendix B, "An Introduction to the C API." This book describes how to write applications using the Open Inventor toolkit. The Inventor Toolmaker, a companion book for the advanced programmer, describes how to create new Inventor classes and how to customize existing classes. The Inventor Mentor contains the following chapters: * Chapter 1, "Overview," provides a general description of Open Inventor concepts and classes and how Inventor relates to OpenGL and the X Window System. * Chapter 2, "An Inventor Sampler," presents a short program that creates a simple object. This program is then modified to show the use of important Inventor objects: engines, manipulators, and components. * Chapter 3, "Nodes and Groups," introduces the concept of a scene graph and shows how to create nodes and combine them into different kinds of groups. * Chapter 4, "Cameras and Lights," describes the camera nodes used to view a scene and the light nodes that provide illumination. * Chapter 5, "Shapes, Properties, and Binding," describes how to create both simple and complex shapes and how to use property nodes, including material, draw style, and lighting model nodes. Binding materials and surface normals to shape nodes is also explained. * Chapter 6, "Text," shows the use of 2D and 3D text nodes. * Chapter 7, "Textures," describes how to apply textures to the surfaces of objects in a scene. * Chapter 8, "Curves and Surfaces," explains how to use NURBS curves and surfaces. * Chapter 9, "Applying Actions," describes how operations are applied to an Inventor scene graph. Actions include OpenGL rendering, picking, calculating a bounding box, calculating a transformation matrix, writing to a file, and searching the scene graph for certain types of nodes. * Chapter 10, "Handling Events and Selection," explains how Inventor receives events from the window system. It also describes how the selection node manages a selection list and performs highlighting. * Chapter 11, "File Format," describes Inventor's interchange file format, used for reading files into Inventor, writing files out from Inventor, and data exchanges such as copy and paste. * Chapter 12, "Sensors," describes how Inventor sensors watch for certain types of events and invoke user-supplied callback functions when these events occur. * Chapter 13, "Engines," describes how you can use Inventor engines to animate parts of a scene graph, or to create interdependencies among the nodes in the graph. * Chapter 14, "Node Kits," introduces node kits, a convenient mechanism for creating groups of related Inventor nodes. Each node kit contains a catalog of nodes from which you select the desired nodes. * Chapter 15, "Draggers and Manipulators," describes how to use draggers and manipulators, which are special objects in the scene graph that respond to user events. Manipulators are nodes with field values that can be edited directly by the user. * Chapter 16, "Inventor Component Library," shows how to use Inventor's Xt components, which are program modules with a built-in user interface for changing the scene graph interactively. It also Chapter 17, "Using Inventor with OpenGL," discusses how to use Inventor with the OpenGL Library.

summary	The paper focuses on the question "How does our built environment, urban culture and architectural production change through humans feeding back into digital systems of pre-fabrication and systems fostering industry 4.0?" It discusses some risks and possibilities of digitisation and the city in an era of sustainability, networked design methods, production processes and digital communication tools in the midst of The Internet of Things. Glimpses into the case studies 'a cloud recycling light', 'dynamic field feedback' and 'urban rigid origami switch' discuss the impact of material behaviour, human and machine feedback into digital systems - their behaviour, their ways of communication, the possibility of optimising future design iterations and their form. All of which may result in new architectural and urban typologies, driven by increasingly agile ways of weaving together complex systems.

summary	Historically, the city represents not just a collection of buildings, but also the concrete cosmology of the world. The importance of geometry in this context is that one can be assured that one’s understanding of the form of the city will correspond to meaning. It is this reading that is the canonical visualization method of the city form. But contemporary urban designers are confronted by cities with overlapping systems of movement and information that has made the reading of geometry insufficient for an understanding of the city. Our interdisciplinary team of researchers has been studying issues related to urban visualization from the perspectives of urban design and computer visualization. Together, we have published work demonstrating how very large and disparate data sets can be visualized and integrated in unique ways. Building on this existing work that connects the two disciplines, this paper presents a survey of six urban design methodologies that may be useful for visualization. Each approach is described through a brief history, a conceptual overview and a diagrammatic exegesis. The conclusion presents an overview of the complementary natures of the discourses in urban design and computer visualization and a prospectus for application of the identified methodologies to computer urban visualization. We conclude that urban theories can inform urban visualization both as a method of informing generation and run-time simplification of 3D geometric modeling and in managing information visualization overlay issues for the very large, over-lapping data sets.

title	Variational modeling of curves and surfaces
source	Eindhoven University of Technology
summary	This dissertation is concerned with curve and surface modeling. In the past, curves and surfaces were modeled by first making wooden models, from which the final results were obtained by means of 'copy-milling'. Since the early 1960s, people have started to use computers to support the design of curves and surfaces. The increasing computing power and the increasing potential of graphical hardware in the last decade has opened many new possibilities for Computer Aided Geometric Design (CAGD). Especially the field of curve and surface modeling is rapidly evolving. This is reflected in the recently started series called 'Geometric Design Publications' that contains several books on curve and surface modeling. The most important applications of curve and surface modeling are found in industrial design, for instance in the automobile, aerospace and shipbuilding industries. An often encountered application is the interpolation and approximation of data with B-splines and Bézier curves and surfaces or other representation schemes. Another related application is variational curve and surface modeling, where one is looking for smooth curves and surfaces that satisfy a number of geometric constraints.

summary	Designers and artists are, by training, accustomed to reversing figure /ground relationships-' They can easily picture and sketch negative (empty) spaces in plan or profile. Such perceptual reversals help them understand the voids between buildings as the dynamic and character-forming entities they are. Traditional drawing techniques like pocheing or hatching, just emphasize the static 2 dimensional aspects of these curious spaces: many sequential or layered views are needed to define their full 3 dimensional volume. Such multiple views are costly to produce and because of the 2 dimensional medium are inherently static and flat. This research applies and further develops an under used visualization technique that depicts negative spaces (voids) as true 3 dimensional solids. It focuses specifically on visualizing outdoor spaces defined primarily by vegetation. The preliminary results are volumetrically revealing depictions of complex spaces. They give the designer and client quick spatial feedback about the intended "'open" space in a given design.

summary	Project development within Industrial Design generates a wide range of information unique to each stage of the process. Managing and monitoring design projects is a particularly complex and challenging task, especially in a classroom setting. The use of a digital platform provides an opportunity to save, organize and guide design projects and facilitates collaborative feedback between students and professors. A preliminary version of the present study was carried out using open-source information technologies: PHP 5.2.8, MySQL 5.1.30, Jquery 1.7.1.mins, Smarty-2.6.9. This proposal seeks to complement the on-site class component in order to provide follow-up, mapping and feedback on design projects.

title	Predicting reflectance functions from complex surfaces
source	Computer Graphics, 26(2):255-264, July 1992
summary	We describe a physically-based Monte Carlo technique for approximating bidirectional re•ectance distribution functions (BRDFs) for a large class of geometries by directly simulating optical scattering. The technique is more general than previous analytical models: it removes most restrictions on surface microgeometry. Three main points are described: a new representation of the BRDF, a Monte Carlo technique to estimate the coef•cients of the representation, and the means of creating a milliscale BRDF from microscale scattering events. These allowthe prediction of scattering from essentially arbitrary roughness geometries. The BRDF is concisely represented by a matrix of spherical harmonic coef•cients; the matrix is directly estimated from a geometric optics simulation, enforcing exact reciprocity. The method applies to roughness scales that are large with respect to the wavelength of light and small with respect to the spatial density at which the BRDF is sampled across the surface; examples include brushed metal and textiles. The method is validated by comparing with an existing scattering model and sample images are generated with a physically-based global illumination algorithm.

summary	During the creative phase, the architect introduces hypotheses and validates them by trying out various adjustments during the process of conception.
