Повний текст джерелаEn aquesta tesi, hem fet una revisió en profunditat de l'estat de l'art del registre 3D, avaluant els mètodes més populars. Donada la falta d'estandardització de la literatura, també hem proposat una nomenclatura i una classificació per tal d'unificar els sistemes d'avaluació i poder comparar els diferents algorismes sota els mateixos criteris. La contribució més gran de la tesi és el Toolbox de Registre, que consisteix en un software i una base de dades de models 3D. El software presentat aquí consisteix en una Pipeline de registre 3D escrit en C++ que permet als investigadors provar diferents mètodes, així com afegir-n'hi de nous i comparar-los. En aquesta Pipeline, no només hem implementat els mètodes més populars de la literatura, sinó que també hem afegit tres mètodes nous que contribueixen a millorar l'estat de l'art de la tecnologia. D'altra banda, la base de dades proporciona una sèrie de models 3D per poder dur a terme les proves necessàries per validar el bon funcionament dels mètodes. Finalment, també hem presentat una nova estructura de dades híbrida especialment enfocada a la cerca de veïns. Hem testejat la nostra proposta conjuntament amb altres estructures de dades i hem obtingut resultats molt satisfactoris, superant en molts casos les millors alternatives actuals. Totes les estructures testejades estan també disponibles al nostre Pipeline. Aquesta Toolbox està pensada per ésser una eina útil per tota la comunitat i està a disposició dels investigadors sota llicència Creative-Commons

Повний текст джерелаCollaboration is vital in today's information age, and tools are increasingly used to bring together teams that are geographically dispersed. Second Life, a 3D virtual world, can incorporate most of the visual, hearing and spatial elements of the real world, and can create a feeling of presence or the sense of actually "being there" for users. Common 2D groupware collaboration tools, such as web conferencing and conference calls used for virtual team collaboration in professional contexts, are key enablers for virtual teams. However, businesses and organizations have not adopted virtual worlds for virtual teams and workgroup collaboration. Shen & Eder (2009) conducted a study using their modified Technology Acceptance Model (TAM) applied to the adoption of Second Life for business purposes. For participants, they used college students who were new to Second Life. The purpose of this research is to examine how the seven factors identified in the Shen and Eder's (2009) extended Technology Acceptance Model (TAM) relate to the behavioral intention to use workgroup collaboration tools in the Second Life using a non-student sample of experienced Second Life users that was more demographically representative of the Second Life population. Although this research supported many of Shen and Eder's findings, it found a negative relationship between the construct of perceived enjoyment and behavioral intent. This finding is important because contrary to positive relationship with gaming and entertainment environments, perceived enjoyment is not an antecedent for behavioral intention of 3D virtual worlds when used for productivity activities. The results of this study may provide insight for tool developers and integrators on where to focus efforts that lead to improved adoption of these workgroup collaboration tools.

Повний текст джерела3D integration technology is driving a strong paradigm shift in the design of electronic systems. The ability to tightly integrate functions from different technology nodes (analog, digital, memory) and physical domains (MEMS, optics, etc) offers great opportunities for innovation (More than Moore). However, leveraging this potential requires efficient CAD tools to compare architectural choices at early design stages and to co-optimize multiphysics systems.This thesis work is divided into two parts. The first part is dedicated to the problem of partitioning a system into multiple dies. A 3D floorplanning tool was developed to optimize area, temperature and the interconnect structure of a 3DIC. Moreover, a meta-optimization approach based on genetic algorithms is proposed to automatically configure the key parameters of the floorplanner. Tests were carried out on architectural benchmarks and a NoC based multiprocessor to demonstrate the efficiency of the proposed techniques.In the second part of the thesis, a hierarchical design methodology adapted to heterogeneous systems is presented. The method combines the bottom-up and top-down approaches with Pareto-front techniques and response surface modeling. The Pareto front of lower level blocks are extracted and converted into predictive performance models that can be stored and reused in a top-down optimization process. The design flow is demonstrated on an operational amplifier as well as on the synthesis of an optoelectronic data link with three abstraction levels

Повний текст джерелаENGLISH ABSTRACT: The aim of this thesis is to develop a generic 3D virtual environment development platform for autism spectrum disorder (ASD) therapy tools. The potential of using computerised therapy tools for ASD therapy is well known. However, the development of such tools is expensive and time-consuming, and is language and culture speci c. This work intends to alleviate these problems. The design of the platform is based on known game engine designs, but adapted for the requirements of ASD therapy tools. It supports standard features such as 3D rendering, animation and audio output. Speci c features, aimed at ASD therapy tools and educational games, included in our engine are: replays, data capturing, remote monitoring over a network and language localisation. We also implemented an input hardware abstraction layer to allow support for non-standard input peripherals in the future, without modifying existing game implementations. Furthermore, to separate the development of games and tools from the engine, we include wrapper libraries in our engine for Lua and Java. We successfully developed our engine and implemented a number of prototype therapy tools and educational games. These implementations confirmed that the engine works as expected. Some of these programs are currently in use at a local primary school.
AFRIKAANSE OPSOMMING: Die doel van hierdie tesis is om 'n 3D virtuele omgewing en ontwikkelingsplatform vir outistiese spektrum versteuring (OSV) terapiemiddels te ontwikkel. Die gebruik van rekenaargebaseerde terapiemiddels vir OSV terapie is bekend. Om sulke terapiemiddels te ontwikkel is egter duur, tydrowend en is dikwels gerig op spesi eke taal- en kultuurgroepe. Hierdie werk het dit ten doel om hierdie probleme te bowe te kom. Die ontwerp van die platform is gebaseer op die ontwerp van bekende videospeletjie-enjins, maar is aangepas vir die benodigdhede van OSV terapiemiddels. Dit ondersteun standaard funksionaliteit soos 3D uitbeelding, animasie en klank. Ons platform sluit in spesi eke funksionaliteit, wat gerig is op OSV terapiemiddels en opvoedkundige speletjies, naamlik: kykweer, datavaslegging, afstandswaarneming oor 'n netwerk en taal-lokalisering. Verder is 'n abstrakte koppelvlak vir toevoerapparatuur ontwikkel, wat dit moontlik maak om in die toekoms nie-standaard toevoerapparatuur te ondersteun, sonder om bestaande speletjies se implementasies aan te pas. Verder, om die ontwikkeling van speletjies en terapiemiddels te skei van die enjin, is koppelvlakke ontwikkel wat dit moontlik maak om die enjin in Lua en Java te gebruik.

Повний текст джерелаIn this dissertation we explore methods of quality control of untextured polygonal models. The tools presented build, evaluate and improve on the field of multiresolution analysis through decimation. We evaluate the quality of models generated through various simplification algorithms to develop efficient measures of image quality. We develop an application for selective, progressive and view-dependent refinement, suitable for browsing 3D models on the internet. Existing work in continuous level-of-detail is extended to allow for faster interpolation between LOD sequences and we present a new LOD control mechanism for maintaining a constant polygon count. We present a generic framework generates multiresolution models through simplification. This allows for the comparison of surface compression methods under the same conditions, and to determine the performance of surface quality measures based on these results. These measures of surface quality are evaluated with both image and model based criteria. We find that the declining volume of a simplified object is a good method of predicting view-independent image quality. Using our generic framework, we extend two applications which can be used to improve rendering performance in a virtual environment. We develop a new selective refinement application which refines only a desired region of the model, suitable for online model browsing. This method provides substantial space saving due to a more compact representation of the simplification hierarchy, and also provides optimisations for use with a client/server model. A novel method of defining smooth mappings between different resolution versions of a model (called continuous level-of-detail) is also defined. This technique greatly improves rendering performance of these models by employing commonly available programmable graphics hardware. We also present a method of controlling the number of polygons in large scenes, which is capable of predictively maintaining a constant frame rate by guaranteeing a polygon budget.

Повний текст джерелаThere has been a significant interest in providing immersive listening experiences for a variety of applications, and recent improvements in audio production have provided the capability for 3D audio practitioners to produce realistic and imaginative immersive auditory scenes. Even though technologies to reproduce 3D audio content are becoming readily available for consumers, producing and authoring this type of content is difficult due to the variety of rendering techniques, perceptual considerations, and limitations of available user interfaces. This thesis examines these issues through the development of a framework of design spaces that classifies how 3D audio objects can be created and manipulated from two different viewpoints : Morphological Analysis of 3D Audio Methods and Practices and Interaction Design. By gathering ethnographic data on tools, methods, and practices of 3D audio practitioners, overviewing spatial perception related to 3D audio, and conducting a morphological analysis on related objects of interest (3D audio objects, interactive parameters, and rendering techniques), we identified the tasks required to produce 3D audio content and how 3D audio objects can be created and manipulated. This work provided the dimensions of two design spaces that identify the interactive spatial parameters of audio objects by their recording and rendering methods, describing how user interfaces provide visual feedback and control the interactive parameters. Lastly, we designed several interaction techniques for 3D audio authoring and studied their performance and usability according to different characteristics of input and mapping methods (multiplexing, integrality, directness). We observed performance differences when creating and editing audio trajectories, suggesting that increasing the directness of the mapping technique improves performance and that a balance between separability and integrality of input methods can result into a satisfactory trade-off between user performance and cost of equipment. This study provided results that inform designers on what they might expect in terms of usability when designing input and mapping methods for 3D audio trajectory authoring tasks. From these viewpoints, we proposed design criteria required for user interfaces for 3D audio user production that developed and improved the framework of design spaces. We believe this framework and the results of our studies could help designers better account for important dimensions in the design process, analyze functionalities in current tools, and improve the usability of user interfaces for 3D audio production tools

Solid Freeform Fabrication processes such as 30 Printing have demonstrated the potential to produce tools with complex internal geometry. This work explores the application of this capability to improved thermal management for injection molding tooling through: i)cooling lines which are conformal to the mold surface which provide improved uniformity and stability of mold temperature and ii) tools with low thermal inertia which, in combination with conformal fluid channels allow for rapid heating and cooling of tooling, thereby facilitating isothermal filling of the mold cavity. This work presents a systematic, modular, approach to the design of conformal cooling channels. Recognizing that the cooling is local to the surface of the tool, the tool is divided up into geometric regions and a channel system is designed for each region. Each channel system is itself modeled as composed of cooling elements, typically the region spanned by two channels. Six criteria are applied including; a transient heat transfer condition which dictates a maximum distance from mold surface to cooling channel, considerations of pressure and temperature drop along the flow channel and considerations of strength of the mold. These criteria are treated as constraints and successful designs are sought which define windows bounded by these constraints. The methodology is demonstrated in application to a complex core and cavity for injection molding. In the area of rapid thermal cycling, this work utilizes the design methods for conformal channels for the heating phases and adds analysis of the packing and cooling phases. A design is created which provides thermal isolation and accommodation of cyclic thermal stresses though an array of bendable support columns which support the molding portion of the tool where the heating/cooling channels are contained. Designed elasticity of the tool is used to aid in packing of the polymer during the cooling phase. Methodology for the design of this structure is presented. A set of tools has been fabricated and subjected to thermal and mechanical tests.

Crespel, Thomas. "Optical and software tools for the design of a new transparent 3D display." Thesis, Bordeaux, 2019. http://www.theses.fr/2019BORD0366.
Повний текст джерелаWe live exciting times where new types of displays are made possible, and current challenges focus on enhancing user experience. As examples, we witness the emergence of curved, volumetric, head-mounted, autostereoscopic, or transparent displays, among others, with more complex sensors and algorithms that enable sophisticated interactions.This thesis aims at contributing to the creation of such novel displays. In three concrete projects, we combine both optical and software tools to address specific applications with the ultimate goal of designing a three-dimensional display. Each of these projects led to the development of a working prototype based on the use of picoprojectors, cameras, optical elements, and custom software.In a first project, we investigated spherical displays: they are more suitable for visualizing spherical data than regular flat 2D displays, however, existing solutions are costly and difficult to build due to the requirement of tailored optics. We propose a low-cost multitouch spherical display that uses only off-the-shelf, low-cost, and 3D-printed elements to make it more accessible and reproducible. Our solution uses a focus-free projector and an optical system to cover a sphere from the inside, infrared finger tracking for multitouch interaction, and custom software to link both. We leverage the use of low-cost material by software calibrations and corrections.We then extensively studied wedge-shaped light guides, in which we see great potential and that became the center component of the rest of our work. Such light guides were initially devised for flat and compact projection-based displays but in this project we exploit them in a context of acquisition. We seek to image constrained locations that are not easily accessible with regular cameras due to the lack of space in front of the object of interest. Our idea is to fold the imaging distance into a wedge guide thanks to prismatic elements. With our prototype, we validated various applications in the archaeological field.The skills and expertise that we acquired during both projects allowed us to design a new transparent autostereoscopic display. Our solution overcomes some limitations of augmented reality displays allowing a user to see both a direct view of the real world as well as a stereoscopic and view-dependent augmentation without any wearable or tracking. The principle idea is to use a wedge light guide, a holographic optical element, and several projectors, each of them generating a different viewpoint. Our current prototype has five viewpoints, and more can be added. This new display has a wide range of potential applications in the augmented reality field

Повний текст джерелаA aquisição de dados sísmicos de reflexão multicanal 3D/4D usando Ocean Bottom NODES de 4 componentes constitui atualmente um sector de importância crescente no mercado da aquisição de dados reflexão sísmica marinha na indústria petrolífera. Este tipo de dados permite obter imagens de sub-superfície de alta qualidade, com baixos níveis de ruído, banda larga, boa iluminação azimutal, offsets longos, elevada resolução e aquisição de tanto ondas P como S. A aquisição de dados é altamente repetitiva e portanto ideal para campanhas 4D. No entanto, existem diferenças significativas na geometria de aquisição e amostragem do campo de ondas relativamente aos métodos convencionais com streamers rebocados à superfície, pelo que é necessário desenvolver de novas ferramentas para o processamento deste tipo de dados. Esta tese investiga três aspectos do processamento de dados de OBSs/NODES ainda não totalmente resolvidos de forma satisfatória: a deriva aleatória dos relógios internos, o posicionamento de precisão dos OBSs e a implementação de algoritmos de migração prestack 3D em profundidade eficientes para obtenção de imagens precisas de subsuperfície. Foram desenvolvidos novos procedimentos para resolver estas situações, que foram aplicados a dados sintéticos e a dados reais. Foi desenvolvido um novo método para detecção e correcção de deriva aleatória dos relógios internos, usando derivadas de ordem elevada. Foi ainda desenvolvido um novo método de posicionamento de precisão de OBSs usando multilateração e foram criadas ferramentas de interpolação/extrapolação dos modelos de velocidades 3D de forma a cobrirem a extensão total área de aquisição. Foram implementados algoritmos robustos de filtragem para preparar o campo de velocidades para o traçado de raios e minimizar os artefactos na migração Krichhoff pre-stack 3D em profundidade. Os resultados obtidos mostram um melhoramento significativo em todas as situações analisadas. Foi desenvolvido o software necessário para o efeito e criadas soluções computacionais eficientes. As soluções computacionais desenvolvidas foram integradas num software standard de processamento de sísmica (SPW) utilizado na indústria, de forma a criar, conjuntamente com as ferramentas já existentes, um workflow de processamento integrado para dados de OBS/NODES, desde a aquisição e controle de qualidade à produção dos volumes sísmicos migrados pre-stack em profundidade.
Ocean bottom recording of 3D/4D multichannel seismic reflection data using 4 component Nodes is a recent and growing major segment in the marine seismic acquisition market in the oil and gas industry. These data provide high quality subsurface imaging with low ambient noise levels, broad bandwidth, wide azimuth illumination, long-offset, high resolution, and recordings of both P and S waves. In addition, data acquisition is highly repeatable and therefore ideal for 4D surveys. However, there are significant differences in acquisition geometry and wavefield sampling, compared to the conventional towed streamer data, which require new tools to be developed for data processing. This thesis investigates three key issues in OBS/NODE data processing that have not yet been satisfactorily fully solved: random clock drifts, accurate OBS positioning and efficient 3D pre-stack depth migration algorithms for accurate subsurface imaging. New procedures were developed to tackle these issues and these were tested on synthetic and real datasets. A new method for random clock drift was created using high order derivatives to detect and correct these residual drifts. A new accurate OBS/NODE positioning algorithm, using multilateration was developed. Tools were created for interpolation/extrapolation of 3D velocity functions across the full extent of the acquisition survey, and robust smoothing algorithms were used to prepare the velocity field to be used for ray tracing and prestack 3D Kirchhoff depth migration, so as to minimize migration artifacts. The results obtained show a clear improvement in all situations analyzed. Dedicated software tools were created and computationally efficient solutions were implemented. These were incorporated into an industry standard seismic processing software package (SPW), so as to provide, together with the already existing tools, a fully integrated processing workflow for OBS/NODE data, from data acquisition and quality control, to the production of the final pre-stack depth migrated seismic volumes.

Повний текст джерелаENGLISH ABSTRACT: 3D virtual environments can be used as therapy tools in patients with autism spectrum disorders (ASDs); however, the development of such tools is time-consuming. A 3D virtual environment development platform for such tools has been developed specifically for the South African context, because of the language and culture sensitivity of these therapy tools. The 3D virtual environment development platform has a Lua scripting interface for specifying logic in the virtual environments. Lua is a textual programming language, and presents a challenge to ASDs therapists’ ability to create therapy tools without engaging an expert programmer. The aim of this research was to investigate the design and implementation of a visual programming environment to support non-expert programmers in scripting within the 3D virtual environment development platform. Various visual program representation techniques, reported in the literature, were examined to determine their appropriateness for adoption in our design. A visual programming language based on the “building-block” approach was considered the most suitable. The research resulted in the development of a visual script editor (VSE), based on an open source framework called the OpenBlocks library. The VSE successfully alleviated the syntax burden that textual programming languages place on non-expert programmers. The fitness of purpose of our VSE was exemplified in a sample 3D virtual environment that was scripted using the VSE. Despite the success, we argue that the applicability of the “building-block” approach is limited to domain-specific programming languages due to the absence of visual expressions for defining user-defined types, and for specifying hierarchy.

Повний текст джерелаAtt utveckla ett nytt flygplanssystem är en väldigt komplicerad arbetsuppgift. Därför används modeller och simuleringar för att testa icke befintliga system, minska utvecklingstiden och kostnaderna, begränsa riskerna samt upptäcka problem tidigt och på så sätt minska andelen implementerade fel. Vid sektionen Vehicle Simulation and Thermal Analysis på Saab Aeronautics i Linköping designas och simuleras varje grundflygplanssystem, ett av dessa system är bränslesystemet. För närvarande används 2-dimensionella rätblock i simuleringsmodellen för att representera bränsletankarna, vilket är en väldigt grov approximation. För att kunna utföra mer detaljerade analyser behöver modellerna utökas med en bättre geometrisk beskrivning av bränsletankarna. Denna rapport går igenom de olika stegen i den framtagna metodiken för att kombinera 3- dimensionella tankmodeller skapade i CATIA med dynamisk simulering av bränslesystemet i Dymola. Den nya 3-dimensionella representationen av en tank i Dymola bör kunna beräkna bränsleytans läge under en simulering av ett manövrerande flygplan. Första steget i metodiken är att skapa en solid modell av bränslet som finns i tanken. Därefter specificeras modellens giltighetsområde och alla tänkbara riktningar hos accelerationsvektorn som påverkar bränslet genereras, dessa används sedan i den automatiserade volymanalysen i CATIA. För varje riktning delar CATIA upp bränslemodellen i ett bestämt antal delar och registrerar volymen, bränsleytans läge samt tyngdpunktens position för varje del. Med hjälp av radiala basfunktioner som har implementerats i MATLAB approximeras dessa data och en surrogatmodell tas fram, denna implementeras sedan i Dymola. På så sätt kan bränsleytans och tyngdpunktens läge beräknas på ett effektivt sätt, baserat på riktningen hos bränslets accelerationsvektor samt mängden bränsle i tanken. Den nya 3-dimensionella tankmodellen simuleras i Dymola och resultaten jämförs med mätningar utförda i CATIA samt med resultaten från den gamla simuleringsmodellen. Resultaten visar att den 3-dimensionella tankmodellen ger en mycket bättre representation av verkligheten och att det är en stor förbättring jämfört med den 2-dimensionella representationen. Nackdelen är att det tar ungefär 24 timmar att få fram denna 3-dimensionella representation.

Повний текст джерелаAbstract A geophysical analysis was carried out to delineate and characterize the Mid-Miocene Moki sandstone reservoir in the Taranaki basin, offshore New Zealand. The study is an effort to use the new 3D seismic from the Parahaki survey to answer some concerns of an earlier 2D seismic line that drilled a dry hole. Well log curves were used to identify two sands within the Moki package (Moki-1 and Moki-2). Amplitude Variation with Offset (AVO) forward modeling was done to evaluate the seismic response of the Moki-1 and Moki-2 sands. The modeling results indicate that the Moki-1 sand exhibits a Class III AVO response, while the result of the Moki-2 show a class 2/2P AVO response. The Far times Far minus Near (Far*(Far- Near) AVO attribute was employed to discriminate hydrocarbon from the background geology. This attribute was applied because gathers were available only over a subset of the survey and not the entire survey area. Intercept/gradient crossplot of gathers close to the well location falls in quadrant IV and shows a wet sandstone background trend, which is consistent with the modeled response. The results from the analysis underscore the application of fluid substitution and AVO synthetic modeling in reservoir seismic studies.

Повний текст джерелаBackground: In today's society, the digital development is constantly advancing in several different areas. In the construction industry, the projects are getting more complex and installations more advanced. At the same time, working methods in the construction industry get behind other industries and may in some cases be perceived as outdated. In order to keep up with other industries when it comes to technology and methods, construction companies need to focus on issues related to the implementation of digital tools in construction phase. Purpose: Research shows a profit for construction projects in both time and cost efficiency when using BIM and digital tools in construction projects. With this starting point, the bachelor thesis will focus on investigating the reason for the limited use of digital tools in production. The report also wants to highlight the difficulties in using digital tools with extra focus on 3D-models and the work on scheduling in production. Method: Theory of the subject has been obtained partly through literature but also in form of previous studies. Through qualitative interviews and a larger quantitative questionnaire survey, the authors wanted to be able to answer the report's questions. Both methods were compared to investigate whether the difficulties with using digital tools were shared by the central resources at Skanska's headquarters and the coworkers in the production and how widely the problem was on Skanska's various projects. Result: The willingness to start working more digital already exists among coworkers. Lack of knowledge and experience leads to that digital tools are experienced as difficult instead of something that will helps employee in the everyday work. With the right resources and education, increased use of digital tools will not be an impossibility for the construction industry in the near future. Consequences: I ncreased use of digital tools throughout the construction process has several advantages. The company will be able to handle more complex projects and increase their operational efficiency which in turn leads to satisfied customers, coworkers and a higher quality on the final product. Increased digitization will most likely make the company more attractive in the labor market. Restrictions: The report is limited to the construction phase use of digital tools with an additional focus on 3D-models and scheduling. In addition, the authors have chosen to delimit the report to Skanska Sweden AB's work on increasing the use of digital tools.
