Att köpa grisen i säcken är ett examensarbete i informationsdesign, med inriktning rumslig gestaltning. Syftet med arbetet är att undersöka hur man kan förmedla och förstå ett rums möjligheter och funktioner genom en 3D- visualisering. Detta för att ta reda på vad som egentligen är relevant att visa i en 3D-visualisering. Arbetet kommer resultera i ett gestaltningsförslag, där ett rums funktioner och möjligheter tillsammans med en 3D-visualisering kommer presenteras. Gestaltningsförslaget strävar efter att underlätta och tydliggöra informationen i en 3D-visualisering av en nyproducerad lägenhet för den potentiella kunden. Från tillvägagångssätten: omvärldsanalys, kvalitativ intervju, telefonintervju, enkäter och förstudie, går det att utläsa att det är viktigt att kunna anpassa sin framtida bostad efter personliga preferenser och behov. Det går alltså inte att förvänta sig att en och samma bostad passar alla. Tillvägagångssätten har sedan kopplats samman med litteratur om: digitala skisser, designfixering, valmöjligheter, rumsupplevelse, med mera. Utifrån Litteraturen framgick det bland annat att ett rum bör anpassas för användaren, att vi uppfattar ett rum på olika sätt och att verklighetstrogna digitala skisser kan vara låsande. Utifrån informationen från tillvägagångssätten och litteraturen har ett gestaltningsförslag tagits fram för att tydliggöra om och hur en potentiell köpare kan anpassa sitt framtida hem. Förslaget innebär ett tillägg till 3D- visualiseringarna för att visa om och hur ett rum går att anpassas för användaren. Med tillägget finns informationen om ett rums funktioner och möjligheter nära till hands utan att störa 3D-visualiseringen och den verkliga uppfattningen av rummet. Denna rapport kan vara av intresse för fasighetsmäklare, 3D-designers och forskare inom design och kommunikation. / Att köpa grisen i säcken is a thesis in information design, with focus on spatial design. The aim is to simplify and clarify the information in a 3D-visualization of a newly built apartment for the potential customer. The study explores how to communicate to potential customers the capabilities and features of a particular room through 3D-visualization. This is to find out what actually is relevant and helpful to show in a 3D-visualization. The work will result in a design proposal, where a room’s features and capabilities along with a 3D- visualization will be presented. From the following approaches and methods: market analysis, qualitative interviews, telephone interviews, surveys and pre-study, it is possible to read that it is important for buyers to be able to adapt their future homes for personal preferences and needs. It should not be expected that a single solution is for everyone. These approaches and methods have then been linked with literature about: digital sketches, design, fixation, choice, spatial experience, and more. From the literature it became apparent, among other things, that a room should be adapted to the user, and that we perceive rooms differently and realistic digital sketches may be a cause of fixation the specific design solution presented. Based on information from the approaches and literature a design proposal has been created to clarify whether and how a potential buyer can adapt their future home. The proposal involves an addition to the 3D-visualizations to show whether and how a room can be adapted to the user. Included in the addition is information about the room’s features and capabilities, placed at the user’s fingertips without disrupting the 3D-visualization or the experience of the room the visualization is intended to communicate. This report may be of interest to real estate agents, 3D-designers and researchers in design and communication.

Master of Landscape Architecture / Department of Landscape Architecture/Regional and Community Planning / Brent Chamberlain / 3D interactive visualizations can communicate complex urban design ideas to communities to improve planning (Bertol & Foell, 1997; Bishop et al., 2008; Griffon et al., 2011; Lange & Bishop, 2005). Unfortunately, many landscape architects, urban designers, and city planners currently re-frame from using such gaming technology capable of creating 3D interactive visualizations (Deane, 2015a). Many firms use verbal descriptions with images. This method is insufficient for facilitating feedback (Bratteteig & Wagner, 2010; Gordon, et al, 2010; Stakeholder Engagement, 2009; Zhang, 2004). According to Lange and Bishop (2005) there is no reason why real-time visualizations should not be used in urban design. Design fields will be moving toward procedural modeling software that is code-based to quickly model urban development (Flachbart & Weibel, 2005). However, this type of software, i.e., ESRI CityEngine, is only being used by approximately 10% of firms (Deane, 2015a). This paper is one of the first to analyze how ESRI CityEngine can be used and improved to support the workflow of landscape architects, urban designers, and planners for urban development projects. The project explored ESRI CityEngine’s procedural modeling and metric capabilities, and how it could be used to visualize a proposed Urban Core Residential District in Manhattan, Kansas. This process involved applying CGA (computer generated architecture) rules to GIS data, to model trees, streetscapes, landscapes, and buildings. Visuals that were produced include a CityEngine Web Scene and a Unity game.

The use of 3D in web applications became available in the mid 1990's with the release of VRML. Today the use of 3D is very common even with web application, and three.js and Babylon.js has become some of the most popular 3D libraries to support the creation of 3D within web services. This project was created together with Explizit Solution AB to test if 3D can improve the user experience within booking systems. The project was to be integrated with Explizit's booking system Adoxa, and make comparisons with a version called Ånghästen which exists in Adoxa. This project was a front end development as the back end already existed within Adoxa, and a survey was made with 15 participants where they tested the original Ånghästen and the new 3D version, and filled out a question form based on that test. The result of the application was a front end 3D visualization of the original Ånghästen. The result of the survey showed that most participants preferred the new 3D version over the original one, and also stated that they would most likely continue to use a 3D application if it was designed well. Many bugs and fixes were discovered during the testing and survey and future work includes continuing to fix these and to make it more dynamic for multiple activities.

3D GIS is the key point of the development in the area in geospatial information domain. 3D visualization techniques, including 3D terrain data processing, the 3D objects modelling , satellite or air photo image texture, model material, level-of-detail terrain, is already gradually mature and had the outstanding performance in the existing 3D GIS software. But 3D spatial analysis function was still lacking in the field of the 3D spatial data processing. The goal of this research is to develop a 3D spatial analysis function for sun shadow in horizontal and vertical direction and to construct a system for 3D geographic objects visualization by using MFC and OpenGL as the development kit. It has some fundamental functions including: camera control, selecting a single face of a object, linking to a database, level-of-detail terrain. The shadow volume algorithm was used for 3D shadow visualization, and light tracing algorithm was used to compute a single face¡¦s culling area, finally sunshine formula of four seasons was utilitized to realize the shadow analysis function.

<p>This study has been carried out as a part of the EC funded project, SMARTDOC IST-2000-28137, with the objective of developing application components that provide highly interactive visualization and collaboration functionalities. The low-level components from the graphics library AVS OpenViz 2.0 are used as the development basis. The application components can be inserted into electronic documents that allow embedded controls such as web documents or Microsoft Word or PowerPoint documents. Instead of displaying results as static images, a SMARTDOC component provides the ability to visualize data and interact with it inside the document. </p><p>Although the principal goal of the SMARTDOC project is to create components in a number of different application domains this study concentrates on developing a medical imaging application component in collaboration with the project partners AETmed and professor Alan Jackson at the University of Manchester. By incorporating the application component into patient reports, the clinicians are provided the ability to interact with the 3D data that is described in the reports. To improve the usability of the component, it makes use of a visual user interface (VUI), which gives the user the ability to interact and change parameters directly in the visualization process. </p><p>Collaborative work over geographical distances is an area that is becoming increasingly common and thus more interesting. As the availability of bandwidth has increased and the communication technologies have advanced, many companies express their interest for this new practical method of work. A company with offices in different countries would benefit from collaborative techniques providing closer cooperation within the company. Specialized institutions and laboratories could gather much experience and information through collaborative research. Medical imaging and visualization technique are areas where distinct disciplines such as networking, user interfaces and 3D visualization naturally can be fused together in order to develop collaborative environments. The visualization components developed within the SMARTDOC project will be the foundation for collaborative application components integrated with the Microsoft DirectX^® multimedia library. In the medical imaging area, collaborative work can be used to improve diagnoses, journaling and teaching. </p><p>This study focuses on developing a prototype of an interactive visualization component for 3D medical imaging and creating a collaborative environment using a multimedia library originally meant for network gaming.</p>

Monitoring volumes of malicious network data for across multiple sources can potentially be overwhelming. As a result, vital data is at a greater risk of being overlooked and the time span for analyzing it could be too lengthy. One way to address this issue is to employ network security visualization techniques to evaluate security risks and identify malicious activity to help mitigate compromised nodes on a network. The purpose of this thesis is to introduce a visualization framework to help reduce task-completion time, enhance situational awareness, and decrease user error of complex visualizations for network security applications. From the developed framework, three techniques are suggested as contributions using visualization and interaction: (1) Stereoscopic visualization technique aims to increase user awareness of vulnerabilities and malicious attacks, (2) the recommender system aims to ensure efficient navigation in complex 3D environments, and (3) an interaction system aims to assist in usability of visualization environments using Natural User Interfaces (NUIs). To investigate the aforementioned techniques, the following tools were created: 3D Stereoscopic Vulnerability Assessment Tool (3DSVAT), Parallel 3D Coordinate Visualization (P3D), NAVSEC recommender system, and Interaction System for Network Security (InterSec).

As técnicas de computação gráfica e visualização científica assumem importância crescente por permitirem representar e manipular dados geológicos tal como são e estão no espaço, isto é, em 3D. Esta dissertação teve por objetivo utilizar ferramentas computacionais para modelar geometricamente e visualizar dados geológicos. Utilizando o programa GOCAD foram construídas superfícies paleobatimétricas das bacias de Santos e Campos para o meso- Neocretáceo a partir dos dados disponíveis na literatura. Sua integração com dados litológicos e estruturais em um único ambiente de visualização 3D permitiu aumentar o potencial de interpretação dos dados originalmente representados em mapas bidimensionais. Para melhor contextualizar a evolução paleogeográfica destas bacias durante a abertura do Atlântico Sul e representar analogias com ambientes de deposição atuais foram construídas superfícies batimétricas do Atlântico Sul do mesocretáceo ao recente e do Mar Vermelho. A partir da utilização de ferramentas de modelagem e visualização 3D de domínio público (VTK) foi desenvolvido um programa computacional (Tensor3D) para a simulação da deformação de objetos geológicos, desde rochas, estruturas tectônicas, domos de sal até bacias, a partir da modificação dos componentes de cisalhamento simples e puro contidos em tensores de deformação... / Research in Geosciences is currently using extensive volumes of heterogeneous data, whose integrated interpretation is complex due to the involvement of different parameters, as well as time and spatial relationships. Computer graphics and scientific visualization techniques are assuming increasing importance as they allow the representation and manipulation of geologic data exactly as they appear in 3D space. The purpose of this work is using computational tools in order to geometrically model and visualize geologic data. Using the GOCAD program, mid-Early Cretaceus paleobathymetric surfaces have been constructed for the Santos and Campos basins, based on published data. Their additional integration with lithologic and structural data in a unified 3D visualization environment, allowed an increase in the interpretative potential of data originally represented using 2D maps. In order to provide a more general context for the paleogeographic evolution of these basins during the opening of the South Atlantic Ocean, and to represent analogies with current depositional environments, paleobathymetric surfaces have been modelled for the South Atlantic Ocean, from mid- Early Cretaceous to present time, and for the present Red Sea. By using 3D open-source modelling and visualization tools (VTK), a computational program (Tensor3D) has been devoloped to simulate deformation of geologic objects, from rocks, tectonic structures, salt domes to basins. This process is controlled by modifyng simple and pure shear components contained in strain tensors... (Complete abstract, click electronic access below)

No. of bitstreams: 1 SantaBarbara_Ailton_D.pdf: 28995237 bytes, checksum: 860d67449ccbd6cc9dec4632d2313d39 (MD5) Previous issue date: 2006 / Resumo: O objetivo deste trabalho foi desenvolver o software In Vesalius, que cria modelos virtuais tridimensionais de estruturas anatõmicas a partir de imagens médicas tomográficas. O software In Vesalius permite a visualização, análise e segmentação dos modelos virtuais, além de viabilizar a confecção de modelos físicos com o auxílio da prototipagem rápida, por meio da exportação de dados no formato apropriado. Para que o software In Vesalius funcione de maneira adequada e gere modelos fiéis e precisos das anatomias que se quer representar, os dados que chegam até ele devem, obrigatoriamente, respeitar determinados parâmetros de qualidade. Este trabalho analisa quais são esses parâmetros e propõe um protocolo para a aquisição de imagens médicas, em exames de tomografia computadorizada, destinadas à reconstrução tridimensional. São apresentadas e discutidas as técnicas envolvidas no processo de transformação dessas imagens em modelos virtuais e, posteriormente, em modelos físicos. A propedêutica por imagem é uma ferramenta chave na medicina - tanto para diagnóstico, especialmente o precoce, quanto para escolha e planejamento terapêuticos. Por isso, o software In Vesalius foi desenvolvido para ser utilizado de forma corrente nos serviços públicos dé saúde brasileiros: trata-se de uma ferramenta simples, robusta, multiplataforma (executável em Windows e Linux), com comandos em português, funções claras e diretas, de fácil manuseio e rápida quando executada em microcomputador PC. Livre e gratuito, o In Vesalius emprega os mais recentes desenvolvimentos da engenharia de software, como a programação orientada a objetos, e integra softwares livres de fontes confiáveis. Sua interface amigável diferencia-o dos produtos similares já existentes - softwares importados com alto custo de aquisição, uso e manutenção, interessantes para pesquisa, mas não para a prática médica diária. A possibilidade de trabalhar com imagens tridimensionais em seu consultório ou no hospital é de grande valor para o cirurgião. Os modelos tridimensionais facilitam e complementam a elaboração mental que o cirurgião faz, a partir de imagens médicas bidimensionais, das estruturas anatômicas de seus pacientes. Com os modelos, ele tem uma visão mais realista dessas estruturas, o que favorece o processo de diagnóstico e a escolha da conduta. Os procedimentos cirúrgicos requeridos no tratamento de diversas patologias podem ser mais simples, baratos e eficientes com o uso das tecnologias de visualização e análise tridimensional de imagens médicas e de prototipagem rápida. Além de facilitar o diagnóstico, os modelos virtuais e físicos permitem que o cirurgião faça um planejamento detalhado e simule com antecedência as intervenções mais complexas - que envolvem, por exemplo, alto grau de deformidade facial ou a colocação de próteses. Os modelos virtuais e físicos ainda podem servir como um meio de compartilhamento de idéias e de integração entre os membros das equipes médicas. Eles melhoram a capacidade de visualização, verificação, interação e otimização diante da situação clínica, possibilitando a realização de testes e exames e a identificação precoce de problemas. O software In Vesalius é uma ferramenta complementar a todos os métodos convencionais utilizados atualmente para planejamento cirúrgico. Seu desenvolvimento é resultado de uma estreita colaboração entre engenharia e medicina: o aperfeiçoamento do software e a adaptação da tecnologia de prototipagem rápida ao uso médico aconteceram com base em experiências clínicas concretas. Ao mesmo tempo, o contato dos cirurgiões com essas novas tecnologias tem contribuído para o avanço da própria prática médica. Espera-se que o processo aqui apresentado da aquisição de imagens tomográficas à confecção de modelos virtuais e físicos - seja crescentemente divulgado e passe a fazer parte da rotina dos procedimentos cirúrgicos, sobretudos nos serviços de saúde pública / Abstract: The aim of this project was to develop the ln Vesalius.. ln Vesalius is software, which, based on computed tomography or magnetic resonances images, creates three-dimensional virtual models of anatomical structures. In Vesalius software not only allows visualization, analysis and segmentation of images, but also generates virtual models required for rapid prototyping, handling the appropriate data format. In order to work adequately and to generate faithful and precise models of the anatomical structures, appropriate data has to be entered in the software, respecting a certain format and parameters of quality. This work show and analyzes what parameters should be set, proposing a protocol for medical images' acquisition destined to the three-dimensional reconstruction. In addition, techniques involved in both virtual and physical models' transformation process are presented and discussed. Propedeutics by image is a key tool in medicine, consisting on non-invasive techniques such as images and models reconstruction for clinical analysis. It is used for diagnosis, especially in precocious cases, being also used for therapeutical decisions and planning. Therefore, In Vesalius is software of extreme importance. The software was developed to be currently used in Brazilian public health services: it is a uncomplicated, robust and multiplatform (can be operated under Windows and Linux) tool. It hascommands in Portuguese and the use of its functionalities is clear and direct, being easy to manipulate. InVesalius can be run on PC microcomputer, while other programs in the area require expensive enterprises. Free and without associated cost, it uses the most recent developments of software engineering. Written with an object-oriented language, it integrates large project's open source codes, as VTK and ITK libraries. In regards to human computer interface, the software's friendly graphical interface differentiates it from the similar products in the market. These products consist of imported soft wares with high cost of acquisition, use and maintenance. In addition, they are interesting for research, but not for the daily medical practice. The opportunity of working with three-dimensional images at one's office or at the hospital is of great value to the surgeon. Three-dimensional virtual models facilitate and complement the model surgeons usually create mentally. This mental mo de! is based on two-dimensional images acquired through medical tests, giving an imprecise idea of the real anatomical structures of one' s patients. Having the models InVesalius generates in hands, a surgeon has a more realistic view of these structures, what enables a more precise diagnostic and the decision for a more adequate procedure according to the case. The surgical procedures required in the treatment of diverse pathologies can be simpler, cheaper and more efficient with the use of the technologies of three-dimensional visualization and analysis of medical images and rapid prototyping. Besides facilitating the diagnosis, the virtual model and physical rapid prototyping mode! allow the surgeons to make a detailed planning and to simulate interventions that are more complex. Virtual and physical models can also serve as a way of sharing ideas and integrating the members of the medical teams. They improve the capacity of visualization, verification, interaction and optimization in face of the clinical situation, making possible the accomplishment of tests and examinations and the precocious identification of problems. In Vesa/ius software is a complementary tool to all the conventional methods used currently for surgical planning. Its development is the result of a narrow collaboration between engineering and medicine. In one hand, the software development and the adaptation of rapid prototyping technology towards medical area have been based on concrete clinical experiences. On the other hand, the contact of the surgeons with these new technologies has been contributing for the advance of medical practice. Mostly, it expects that the process presented in this document - from the acquisition of tomography images to the creation of virtual and physical models - will be increasingly divulged and become a part of the routine of the surgical procedures, especially in the public health services / Doutorado / Materiais e Processos de Fabricação / Doutor em Engenharia Mecânica
