title Game Engine Computation for Serious Engineering: Visualisation and Analysis of Building Facade Movements as a Consequence of Loads on the Primary Structure
doi https://doi.org/10.52842/conf.acadia.2017.146
source ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 146-153
summary This paper demonstrates the innovative use of game engines as a tool in the analysis and communication of complex structural engineering. It specifically looks at the relationship between a building’s primary structure and its façade. The analysis and visualisations, scripted using the Game Engine Unity3D, focuses on visualising the implications of movements from the primary structure [under various load cases] on the façade. This paper describes the novel process by which Unity3D is utilised to create an applet which imports displacements from structural software and post-processes the data to visualise the complex effect on façade panels according to its support conditions. It demonstrates that visualising facade movements in real-time, as opposed to current, static report-based descriptions, provide access for the comprehension of more complex building systems. This therefore has the possibility to reduce safety factors applied to facade movement joints.

title Building Resilience - Using Parametric Modelling and Game Engines to Simulate the Impacts of Secondary Structures in Bushfire Events
doi https://doi.org/10.52842/conf.caadria.2022.2.749
source Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 749-758
summary Bushfires are a global phenomenon, closely connected to climate change and safety, resilience and sustainability of cities and human settlements. Government agencies, architects and researchers across institutions are committed to improving Australia‚s resilience to bushfires yet grappling with ways to further mitigate risks. ‚Build back better‚ is the often-used phrase to support bushfire resilience, yet there remains a limited understanding of how secondary structures, such as storage sheds, garages, and fences contribute to or mitigate fire loss. These secondary structures are integral to properties yet fall, largely, outside land use planning approval processes and other regulations. Computational modelling can be adapted to deliver visualisations that increase awareness. We developed several simulation approaches which addressed distances, relationship to and the construction materials of secondary structures, terrain slopes and environmental forces. We conclude that gaming engines may offer the optimal immersive opportunity for residents and others to visualise fire risks related to secondary structures to increase awareness and improve bushfire readiness behaviours.

title Supporting Design Learning with Design Puzzles

summary The design process is a puzzle-solving process. Two groups of researches that share many similarities with Puzzle-solving design process are the process of game-playing and playful learning. The main argument is using the “playing” characteristics to amplify and explore the learning process, furthermore the design process. In addition, puzzles imply playful exploration that utilizes the characteristics of “playing a game” as “solving a puzzle”. Puzzle making and puzzle solving provides an incremental exploration mechanism that is more intuitive for design learning. For understanding and realizing puzzles in design learning, this research is divided into two stages of researches—manual design puzzles and interactive design puzzles. By analysing the outcome from manual design puzzles, this research proposes a framework called (interactive) “design puzzles”. The conceptual and implementation framework of this view of design is elaborated in this paper as well as a particular design puzzle called puzzle collage is described as the realization of design puzzles.

title The Didactic Triangle - Using CAD, Photography and Descriptive Geometry as Educating Tools with Mutual Influence
doi https://doi.org/10.52842/conf.ecaade.2004.558

summary Teaching of architectural photography is still not very popular at universities. We developed a didactic concept of teaching architectural photography in response to caad and to descriptive geometry. The first edge of the triangle (descriptive geometry): By having knowledge in descriptive geometry, students will be more aware of geometrical context in caad and in photography. On the other hand the teaching and understanding of descriptive geometry is much easier, when students have already a basic knowledge of photography. The second edge of the triangle (caad, animation): This kind of teaching architectural photography is not only necessary to open the eyes for „young“ student to learn photography - it also helps to understand the basics of constructing perspectives in descriptive geometry or computer aided design up to different kinds of visualisation. The third edge of the triangle (photography): In the age of non-slr-cameras students are no longer used to take sophisticated photographs. They are mostly only able to take snapsshots (even in the time of digital cameras). One of our main methods is to make them acquainted to slrcameras (analog and digital), to tripods and spirit levels as essential tools and to teach the basic geometrical context. The didactic concept is continued by teaching knowledge about colours, light, different points of view etc. Our didactical concept („Didactic Triangle“) is based on teaching all three elements (photography, caad, descr. geometry) by the same teacher in the same semester to the same students. This guarantees the mutual understanding of the three disciplines. Interactive, digital teaching elements (virtual „mock-up-studio“) support the acceptance.

summary Contemporary computer techniques offer many new opportunities to engage citizens into the planning process. There are new possibilities of interaction, introducing an observer into the “game”. The research project presented in the paper assumes the use of a visual 3D language which consists of a series of schematic types of buildings. They form a language which is easy to understand both by professionals and by laymen. Understanding is the very first step towards getting convinced by the ideas presented. The next step is interaction - the user’s action induces the response of the system. The solution proposed by the user meets an evaluation from the part of the system which evokes the user’s interest - in the case presented here the evaluation introduces the simulation of future state of the site. The problem posed is to find out the best way to convince people that some places are less or more suitable for settlement, depending on the media present there, distance from the urban areas and the environment protection. The attempt to create a tool which could be helpful in an educational process is described in the paper. The idea is to prepare a form of a master plan record which uses the visual 3D language and may be accessed via World Wide Web pages. The paper formulates the assessments for the software described above and examines the possibility to create an application. The trial to prepare a web based service using the flash and shockwave technology is presented.

title Identification and Visualisation of Construction Activities’ Workspace Conflicts Utilising 4D CAD/VR Tools
source eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary This work addresses the problem arising on all construction sites: the occurrence of workspace interference between construction activities. From a site space planning context, this problem can lead to an inevitable roadblock to the progress of the scheduled construction operations. In real situations, when the spatial congestions occur, they could reduce productivity of workers sharing the same workspace and may cause health and safety hazard issues. The aim of this paper is on presenting a computer-based method and developed tool to assist site managers in the assignment and identification of workspace conflicts. The author focuses on the concept of ‘visualising space competition’ between the construction activities. The concept is based on a unique representation of the dynamic behaviour of activity workspace in 3D space and time. An innovative computer-based tool dubbed PECASO (Patterns Execution and Critical Analysis of Site-space Organisation) has been developed. The emerging technique of 4D (3D + time) visualisation has been chosen to yield an interesting 4D space planning and visualisation tool. A multi-criteria function for measuring the severity of the workspace congestions is designed, embedding the spatial and schedule related criteria. The paper evaluates the PECASO approach in order to minimise the workspace congestions, using a real case study. The paper concludes that the PECASO approach reduces the number of competing workspaces and the conflicting volumes between occupied workspace, which in turn produces better assessment to the execution strategy for a given project schedule. The system proves to be a promising tool for 4D space planning; in that it introduces a new way of communicating the programme of work.

source CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 107-116
summary In this research, Quake Engine on PDA (Pocket Quake) is modified and developed to make an appropriate environment for collaborative design work in the representation phase for the architectural design teams. The system is being designed for working in the centralized environment by using central server, such as when the designing team has changed 3D Model Information and uploaded to the server then the PDA client will change the same 3D Model automatically. Game Engine will be used to develop this presentation’s tool by designing new user interface and functions for working in PDA. The trial project, The Victory Monument’s Area Development Project, will make the Online Interactive Presentation by using 3D Game Engine on PDA to reconstruct around The Victory Monument in Bangkok. Hopefully, this will make the Virtual World Online anywhere, anytime being more available and give the comparison between the site existing and the new architectural form which designed on the site for good understanding about what the design answers.

summary This paper reviews existing research into real-time visualization in architecture, urban design and landscape architecture and describes a University of Lincoln project exploring the application of this technology to participatory design. Staff at the School of Architecture have used 'Virtools Development', a computer game prototyping package, to help residents in Hull, UK, to visualize and interact with a design proposal for a 'home zone' in their neighbourhood, arrived at as part of a wider participatory process. This paper evaluates computer game technology in relation to more conventional participatory tools. It is difficult to justify using the technology to create simple 'walk-through' simulations of design proposals, it argues. In such cases, the benefits real-time visualization offers over non-interactive video are largely outweighed by the technical difficulties involved in the production and use of real-time environments.

source Environmental Simulation - New Impulses in Planning Processes [Proceedings of the 5th European Architectural Endoscopy Association Conference / ISBN 3-922602-85-1]
summary This contribution documents the developments, results and findings of an experimental design visualisation and presentation exercise entitled ‘A Different View of Delft’. The primary aim of this project was to make students aware of the potentials of the active utilisation of physical models for the sake of designerly enquiry. Furthermore the ambition was to explore new ways of using such model ‘environments’ for the benefit of design communication and presentation. For this exercise a ‘game’ situation with clear constraints and rules was developed beforehand. The students were to work out a proposal for a new exhibition space, as an annex to a – hypothetical – existing museum. The new space was to create a fitting ‘setting’ for a single work of art: Johannes Vermeer’s famous View of Delft. The maximum contours of the new exhibition space were given, along with clear guidelines concerning which walls and roof segments might be (partly) opened. The emphasis lay on the viewer’s ‘approach’ to the painting, its positioning and ‘framing’ in an architectural context. A designerly search involving form and space, the choice of colours and materials and particularly the strategic use of (natural) lighting.

summary The paper deals with a close examination of several contemporary game engines regarding their usability for architectural visualisation that was conducted by third to fifth year students in a seminar context. The study examines the technology of these game engines with the main focus on graphic quality and adaptability to architectural purpose. The evaluation included not only the workflow of importing the 3D model into the engine but also general handling of the software and its user interface. The documentation of the test process and the evaluation of the various engines have been documented in a wiki compiled and written by the students. The information therein and the cost-benefit analyses provided for every engine should assist future users to quickly find the most suitable game engine for their specific purposes.

summary This paper proposes virtual spaces designed in Game Engines promote a form of inhabitant hyperactivity. Allowing quick navigation between distant spaces the Game Engine fosters an appreciation of movement over pause, which may be to the detriment of architectural visualisation. This paper presents a series of three case studies that explore the notion of Real-Time Streaming Data within RTVE to enrich and enhance Virtual Environments. This paper proposes the notion of 'Digital Ephemera' can help produce a more immersive virtual environment. Based on the examination of these case studies, the paper concludes on a motion that breaking down the inherent 'stillness' of traditional RTVE's can be avoided by developing an environment that taps into data streaming and monitoring services to enhance the inhabitant experience.

title Global Visualisation Engines – Issues for Urban Landscape Planning Participation Processes
source Digital Design in Landscape Architecture 2008, Proceedings at Anhalt University of Applied Sciences, 29-31 May 2008
summary Traditional planning processes use two-dimensional drawings, plans, sections, elevations and artists’ impressions to communicate design intent to interested parties. Three-dimensional computer visualisation technologies that support the planning process raise institutional and organisational challenges as their perceived benefits are considered. Virtual Reality (VR) models add interactivity and immersiveness to landscape visualisations but require appropriate technical input and management. This paper explores two main themes. Firstly, how interactive 3D computer simulations of planning proposals can be adopted to successfully improve the traditional process. It reports on a pilot study to examine how architects, clients, planning officers and university researchers have worked together to systematically examine and analyse this changing process. It reports on issues concerned with ownership of city models, the roles and the compatibility, accuracy and remote sharing of urban data. Secondly, we explore the emerging theme of web-based GIS applications and their impact on architectural visualisation. The process of placing urban data onto Google Earth was tested and the resulting issues emerging with this software, including IT and data management and accuracy issues for suitable architectural visualisation are discussed. The study also reports and offers an overview of placing accurate urban landscape data onto Google Earth and a discussion of using this method for online public participation and communicating technical building information.

title Using 3D Design Software, BIM and Game Engines for Architectural Historical Reconstruction
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 493-509.
summary The use of digital tools has become a tremendous aid in the creation of digital, historical reconstructions of architectural projects. Regular visualization techniques have been used for quite some time and they still pose interesting approaches, such as following cinematic techniques [1]. While common visualizations focus on pre-rendered graphics, it is possible to apply Game Engines [2] for real-time architectural visualization, as witnessed by [3] and [4]. In the course of our teaching and research efforts, we have collected experience with several visualization and modeling techniques, including the use of gaming engines. While the modeling of qualitative geometry for use in regular visualization already poses an elaborate effort, the preparation of models for different uses is often not trivial. Most modeling systems only support the creation of models for a single amount of detail, whereas an optimized model for a real-time system will have fairly different constraints when compared to non-real-time models for photorealistic rendering and animation. The use of parametric methods is one usable approach to tackle this complexity, as illustrated in [4]. One of the major advantages of using parametric approaches lies precisely in the possibility of using a single model to generate different geometry with control over the amount of detail. We explicitly tackle this in a Building Information Modeling (BIM) context, as to support much more than purely 3D geometry and visualization purposes. An integrated approach allows the same model to be used for technical drawings in 2D and an optimized 3D model in varying levels of detail for different visualization purposes. However, while most Building Information Modeling applications are targeted to current architectural practice, they seldom provide sufficient content for the recreation of historical models. This thus requires an extensive library of parametric, custom objects to be used and re-used for historically accurate models, which can serve multiple purposes. Finally, the approach towards the historical resources also poses interpretation problems, which we tackled using a reasonably straightforward set up of an information database, collecting facts and accuracies. This helps in the visualization of color-coded 3D models, depicting the accuracy of the model, which is a valuable graphical approach to discuss and communicate information about the historical study in an appealing format. This article will present the results of different reconstruction case studies, using a variety of design applications and discuss the inherent complexity and limitations in the process of translating an active, evolving model into an environment suitable for use in a real-time system. Especially workflow issues are identified, as the translation of the model into the game engine should be repeated several times, when the model is further refined and adapted. This used to involve a large amount of repetitive work, but the current crop of game engines have much better approaches to manage the updating of the geometry.

summary This article explores the representation of historical transformations in the Square of XV de Novembro, one of Rio de Janeiro's oldest and historically significant locations. A geometric modeling methodology is employed to visually represent the profound alterations in the landscape over time, selecting pivotal periods to offer a detailed spatial perception and virtually reconstruct lost landmarks. The utilization of game engines facilitates a first-person perspective of the model, which could further enhance the immersion. Moreover, this approach enables new interpretations of existing historical documents while also providing new material about Brazil’s and Rio de Janeiro’s history. To this end, the research combines historical simulation with an interpretative investigation, utilizing diverse historical materials. The chosen methodology provides a multifaceted understanding of the location's evolution and its significance in Brazil's history.

summary This study aims to investigate the accuracy of representing daylit spaces using game engine-based rendering techniques, compared to validated benchmark renderers and real-life measurements. Two daylit case studies- reflecting different complexity levels and spatiotemporal settings- were rendered in a game engine using a traditional rendering technique and real-time raytracing. Illuminance levels at selected points were measured in Unreal Engine and were compared to those calculated in a validated light simulation tool and an illuminance meter for the simplified and complicated case studies, respectively. In both cases, traditional technique cited a high variance in illuminance levels compared to the references. In the simplified model, real-time ray tracing showed the lowest average error compared to the validated simulation results. In the complicated model, the average error of such technique was close to that of the validated simulation, compared to the actual illuminance measurements. This study illustrates the added benefits of using real-time ray tracing in game engines over traditional ray tracers to offer an immersive and interactive experience of virtual daylit spaces, without sacrificing the quantitative accuracy of the simulated luminous environments.

summary This paper makes a case for exploring the feasibility of utilizing the advanced graphics and sound systems of contemporary gaming engines to promote architecturally relevant work. Gaming engines, while developed largely for the PC entertainment industry, have vast potential for application in architecture. This paper will explore the depth of this potential and will outline work demonstrating the advantages and the limitations of this technology. The supporting research and observations examine the technology and reveal its potential usefulness as an instructional or depictive authoring tool. Game engines were selected that had appropriate graphical prowess, but were customizable as to allow the removal of game-specific features (to create a “professional” user interface). Projects were authored that expressed complex building details using the engine for visual depiction. The details, which included constructional components, structural assemblies, or simple design nuances, were modeled with 3D geometry and realistically textured and lighted. The game engine allowed one user or many remote simultaneous users in the virtual environment to interactively explore the presentation in real time. Scripts were developed to encourage end-users to interactively disassemble or reassemble building components as desired. Audile and/or text-based information regarding the assembly sequence were provided by exploiting the game interface features. Furthermore, interactive object scaling was provided to facilitate analysis of component relationships.
