title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
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. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

title	A Study of The Virtual Reality Simulation System for LRT Projects Towards Sustainable City
doi	https://doi.org/10.52842/conf.caadria.2009.023
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 23-32
summary	Recently, many cities in Japan and in other developed nations face problems such as decadence of downtown areas, aged society with a fewer number of children, dependence on automobile transport, etc. And redesign of public transportation services (e.g. tram) is thought to be one of the solutions for these problems. The introduction of LRT is investigated in various places, however, when a public traffic system like LRT is introduced, it is necessary to consider not only the transportation oriented aspects, but also landscapes and plans for a future sustainable city. Therefore, city planners are required to promote workshop-type in the design process to deal with citizens, companies, NPOs, etc. In this research, both components of the VR system for LRT projects and the system that enables the examination from various aspects of traffic, landscapes, city planning, etc., were studied.

title	Multi-modal simulation for urban mobility analysis: An approach based on a model of behaviour and infrastructure-related anomalies
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	This paper presents a distributed simulation system for urban scenarios where infrastructure anomalies are common, such as those present in Latin-American cities. A microscopic-based model has been developed in order to represent the behavioural characteristics of the different mobility actors in a discrete lattice. The visualization component allows an interactive and immersive experience of the simulation results, providing a detailed point of view (focus) in the global environment (context). It is possible to empower the users’ interaction through devices for control and navigation of the data visualization.

summary	We examine an open source 3d suite of tools called blender, as a tool for architectural design. The unique features of blender are examined in terms of ease of use and integrated nature since blender incorporates a simulation engine and a game engine that can be used creatively in the design process. The unique data structure of Blender is examined with the features and work flow that this structure brings in the design process. Also a simple comparison is made between Blender and 3ds max in terms of features and workflow as visualization tools together with an assessment of a two year seminar that took place in the Department of Architecture, in Volos Greece.

source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 140-151
summary	Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.

title	The Study of Building Management by using 3D Digital Modeling and Database: ABFM
doi	https://doi.org/10.52842/conf.caadria.2009.235
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 235-243
summary	The principal objective of building management is to control facilities planning and facilities operations and maintenance, that effective criteria in strategic planning about preventive maintenance and predictive maintenance. The key of success in managing the building and facilities is all about collecting and interpreting data on diverse facets of property use. Computer databases are the ideal vehicles in which to log, store and manipulate data; almost unlimited information can be measured and entered en masse. The strength of such information storage is its capacity for expansion and the diversity of subject; it becomes large and requires greater and greater operator familiarity with its structure in order to interrogate successfully. The ultimate solution is to computer–base the entire operation, by using the three-dimensional building modelling to control the operation. This solution will simulate building in virtual environment and the building system data (Architectural part and Engineering part) will collect in digital data type. The digital data will classification and made three-dimensional database relations. This research focus in three sections of the operation as three-dimensional database relationship, topological simulation and smart system, that applied to generate the prototype building management application “Architecture Building Facilities Management: ABFM”.

title	Designing for the unpredictable: Novel model for the design of emergence through real-world behavior
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 847- 860
summary	Most current approaches to unpredictability, within architectural discourse, lie either in the design of unbuildable emergent shapes or in performance simulations to test already designed outcomes. Even though some recent explorations have enabled the construction of emergent shapes, the unpredictability of real-world behaviors as the rules’ source for the unpredictability of shape generation remains unexplored. This paper proposes a novel model for the design of unpredictable buildable shapes, based on real-world behaviors. Initially, current methodologies are studied in order to find how they deal with the unpredictability of shape generation and real-world behaviors. Finally, a comprehensive novel model is proposed and tested through an empirical experiment, to show how it can be applied in architecture.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The knowledge of latest technology that allows the development of competitive products in reduced times is crucial to guarantee a sustainable growth of the national industry. This work presents the development of a computational system for the Virtual Design of products, the VirtusCADE, which is a CAD/CAE interactive software (Computer Aided Design/Computer Aided Engineering). The VirtusCADE includes 3D geometric modeling of surfaces and solids and mesh generation. The system uses the parametric modeling of surfaces, including algorithms for determination of intersection between surfaces and for triangular mesh generation in trimmed parametric surfaces. The graphical interface is interactive and allows the direct real time manipulation of objects (lines, surfaces and solids) in 3D using the OpenGL technology. The system prioritizes the usability, implementing several graphic tools that facilitate the manipulation in 3D. The VirtusCADE contemplates the structural simulation through the Finite Element Method. The code architecture is based on oriented object programming, which allows great scaling capability for the implementation of new tools. This project has great applicability in numerical simulation of physical phenomena, such structural analysis of buildings, vehicles parts, with impact in the industries of civil construction, metal-mechanics, aerospatial, naval and automotive.

summary	In a world where sustainability, ecology, collaboration and performance are common concerns, “joining” is a keyword, expressing the idea of an integration of knowledge, efforts and processes aimed at a better future. The CAADFutures 2009 conference thus intends to join professional and scientific reflections, with the notable input of new disciplines that are also concerned with digital design, such as industrial design and civil engineering. As a result, a vivid dialogue is established between different cultural approaches, computational methods and philosophical positions. The field of computer-aided design is faced with many challenges. CAADFutures 2009 addresses the search for new paradigms for sustainable design, the issues derived from the “digital thinking” embedded in current CAD systems as opposed to the needed “design thinking”, and many more pressing questions such as those of heritage, advanced geometry and parametric design, CAD education, virtual environments, interaction and new technologies, simulation, building performance, rapid prototyping, management, collaboration and ideation.

summary	In his book “Cinema as an Art”, Rudolf Arnheim states that cinema (art) cannot achieve to realize the mechanical reproduction of the real (nature) because of technical limitations but also states that these limitations are compulsory for the production of art. According to Arnheim, these limitations cause artists to interpret the real (nature) and to materialize impressive expressions. Architecture presents its productions to its viewers (customers) using some kind of media, before materializing them in the physical world. The most common ones nowadays are technical drawings (perspectives), models, photographs and computer aided models and animations. The architect makes impressive expressions based on the technical limitations of the medium he/she uses. With the computer technology, simulation gives possibilities to the architect for presenting and experiencing his/her art very close to reality. Simulation is the best way to reproduce the reality mechanically, when it is compared to other mediums. In this study, simulation’s potential as an architectural presentation technique is examined through Arnheim’s vision and Rembrandt’s painting “Staalmeesters”.

title	3D Model and Decision Support System for Fire Safety: A case study of Kingdom of Bahrain
source	Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 419-430
summary	Fire agencies on all levels try hard to save lives, properties, and natural resources. Accurate access to critical information is essential in this regard, many agencies around the world have embraced GIS as a tool that helps them balance needs, uses, and hazards to promote sustainability of the environment while identifying and limiting vulnerability. At Kingdom of Bahrain, Ministry of interior established the Geographic Security System (GSS) to enhance the emergency response. The 3D of the GSS Consisted of 3 main parts: (1) 3D for terrain model, (2) 3D model for entire targeted zones, and (3) 3D models for individual buildings. In this paper, the integration between GSS system and 3D model will be illustrated, and how this kind of integration could enhance decision support system (DSS) for fire safety at kingdom of Bahrain. On other hand, we will highlight the technical and legislation difficulties faced in this project. Also, the future steps to enhance DSS will be discussed.

summary	The next major revolution for design is to bring the natural user interaction into design activities. Graphical User Interfaces (GUI) brought a new approach that was more effective compared to their conventional predecessors. In recent years, Natural User Interfaces (NUI) have advanced user experiences and multi-touch and gesture technologies provide new opportunities for a variety of potential uses in design. Much attention has been paid to leverage in the design of interactive interfaces. The mouse input and desktop screen metaphors limit the information sharing for multiple users and also delayed the direct interaction for communication between each other. This paper proposes the innovative method by integrating game engine ‘Unity3D’ with multi-touch tangible interfaces. Unity3D provides a game development tool as part of its application package that has been designed to let users to focus on creating new games. However, it does not limit the usage of area to design additional game scenarios since the benefits of Unity3D is allowing users to build 3D environments with its customizable and easy to use editor, graphical pipelines to openGL (http://unity3d.com/, 2010 ). It creates Virtual Reality (VR) environments which can simulates places in the real world, as well as the virtual environments helping architects and designers to vividly represent their design concepts through 3D visualizations, and interactive media installations in a detailed multi-sensory experience. Stereoscopic displays advanced their spatial ability while solving issues to design e.g. urban spaces. The paper presents how a multi-touch tabletop can be used for these design collaboration and communication tasks. By using natural gestures, designers can now communicate and share their ideas by manipulating the same reference simultaneously using their own input simultaneously. Further studies showed that 3Dl forms are perceived and understood more readily through haptic and proprioceptive perception of tangible representations than through visual representation alone (Gillet et al, 2005). Based on the authors’ framework presented at the last CAADFutures, the benefits of integrating 3D visualization and tactile sensory can be illustrated in this platform (Chen and Wang, 2009), For instance, more than one designer can manipulate the 3D geometry objects on tabletop directly and can communicate successfully their ideas freely without having to waiting for the next person response. It made the work more effective which increases the overall efficiency. Designers can also collect the real-time data by any change they make instantly. The possibilities of Uniy3D make designing very flexible and fun, it is deeply engaging and expressive. Furthermore, the unity3D is revolutionizing the game development industry, its breakthrough development platform for creating highly interactive 3D content on the web (http://unity3d.com/ , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

summary	This article presents an application of Augmented Reality technology for interior design. Plus, an Educational Interior Design Project is reviewed. Along with the dramatic progress of digital technology, virtual information techniques are also required for architectural projects. Thus, the new technology of Augmented Reality offers many advantages for digital design and construction fields. AR is also being considered as a new design approach for interior design. In an AR environment, virtual furniture can be displayed and modified in real-time on the screen, allowing the user to have an interactive experience with the virtual furniture in a real-world environment. Finally, this study proposes a new method for applying AR technology to interior design work, where a user can view virtual furniture and communicate with 3D virtual furniture data using a dynamic and flexible user interface. Plus, all the properties of the virtual furniture can be adjusted using occlusion based interaction methods for a Tangible Augmented Reality.
