Der volle Inhalt der QuelleA visualização volumétrica é uma importante técnica para a exploração de dados tridimensionais complexos, como, por exemplo, o resultado de análises numéricas usando o método dos elementos finitos. A aplicação eficiente dessa técnica a malhas não-estruturadas tem sido uma importante área de pesquisa nos últimos anos. Há dois métodos básicos para a visualização dos dados volumétricos: extração de superfícies e renderização direta de volumes. Na primeira, iso-superfícies de um campo escalar são extraídas explicitamente. Na segunda, que é a utilizada neste trabalho, dados escalares são classificados a partir de uma função de transferência, que mapeia valores do campo escalar em cor e opacidade, para serem visualizados. Com a evolução das placas gráficas (GPU) dos computadores pessoais, foram desenvolvidas novas técnicas para visualização volumétrica interativa de malhas não-estruturadas. Os novos algoritmos tiram proveito da aceleração e da possibilidade de programação dessas placas, cujo poder de processamento cresce a um ritmo superior ao dos processadores convencionais (CPU). Este trabalho avalia e compara dois algoritmos para visualização volumétrica de malhas não-estruturadas, baseados em GPU: projeção de células independente do observador e traçado de raios. Adicionalmente, são propostas duas adaptações dos algoritmos estudados. Para o algoritmo de projeção de células, propõe-se uma estruturação dos dados na GPU para eliminar o alto custo de transferência de dados para a placa gráfica. Para o algoritmo de traçado de raios, propõe-se fazer a integração da função de transferência na GPU, melhorando a qualidade da imagem final obtida e permitindo a alteração da função de transferência de maneira interativa.
Volume visualization is an important technique for the exploration of threedimensional complex data sets, such as the results of numerical analysis using the finite elements method. The efficient application of this technique to unstructured meshes has been an important area of research in the past few years. There are two basic methods to visualize volumetric data: surface extraction and direct volume rendering. In the first, the iso-surfaces of the scalar field are explicitly extracted. In the second, which is the one used in this work, scalar data are classified by a transfer function, which maps the scalar values to color and opacity, to be visualized. With the evolution of personal computer graphics cards (GPU), new techniques for volume visualization have been developed. The new algorithms take advantage of modern programmable graphics cards, whose processing power increases at a faster rate than the one observed in conventional processors (CPU). This work evaluates and compares two GPU- based algorithms for volume visualization of unstructured meshes: view- independent cell projection (VICP) and ray-tracing. In addition, two adaptations of the studied algorithms are proposed. For the cell projection algorithm, we propose a GPU data structure in order to eliminate the high costs of the CPU to GPU data transfer. For the raytracing algorithm, we propose to integrate the transfer function in the GPU, which increases the quality of the generated image and allows to interactively change the transfer function.

Der volle Inhalt der QuelleVisualization of large scale time-varying volumetric datasets is an active topic of research. Technical limitations in terms of bandwidth and memory usage become a problem when visualizing these datasets on commodity computers at interactive frame rates. The overall objective is to overcome these limitations by adapting the methods of an existing Direct Volume Rendering pipeline. The objective is considered to be a proof of concept to assess the feasibility of visualizing large scale time-varying datasets using this pipeline. The pipeline consists of components from previous research, which make extensive use of graphics hardware to visualize large scale static data on commodity computers.
This report presents a diploma work, which adapts the pipeline to visualize flow features concealed inside the large scale Computational Fluid Dynamics dataset. The work provides a foundation to address the technical limitations of the commodity computer to visualize time-varying datasets. The report describes the components making up the Direct Volume Rendering pipeline together with the adaptations. It also briefly describes the Computational Fluid Dynamics simulation, the flow features and an earlier visualization approach to show the system’s limitations when exploring the dataset.

Der volle Inhalt der QuelleLos adelantos actuales en imagenes médicas están permitiendo a los especialistas obtener información cada vez más precisa de las estructuras anatómicas del organismo humano. Mediante la utilización de diferentes técnicas de visualización, los expertos pueden obtener imágenes de calidad para los huesos, tejidos blandos y torrente sanguíneo, entre otros. Los actuales algoritmos de procesamiento de imágenes garantizan el equilibrio entre la resolución y la exactitud de la información. Paralelamente, los médicos están más familiarizados con las estructuras tridimensionales reconstruidas a partir de imágenes en dos dimensiones. Por otro lado, los hospitales están incorporando la tele-medicina y el tele-diagnóstico entre sus soluciones técnicas. Las aplicaciones cliente-servidor permiten estas funcionalidades. En ocasiones el uso de dispositivos móviles es necesario debido a su fácil mantenimiento y a su portabilidad. Sin embargo, el tiempo de transmisión de la información volumétrica así como el bajo rendimiento del hardware en estos dispositivos, hacen que el diseño de sistemas eficientes de visualización sea todavía una tarea compleja. El objetivo principal de esta tesis es enriquecer la experiencia del usuario en la visualización interactiva de modelos volumétricos de medicina en dispositivos de bajo rendimiento. Para conseguir esto, se ha puesto en práctica la implementación de un mecanismo de compresión/descompresión que depende de funciones de transferencia para optimizar la transmisión, reconstrucción y la visualización en estos dispositivos. Esta tesis, por lo tanto, propone varios esquemas para aprovechar el uso de las funciones de transferencia (TFs) e incrementar el ratio de compresión del volumen durante la transmisión a los dispositivos móviles. De acuerdo con nuestros conocimientos, ninguna de las técnicas descritas en los trabajos presentados anteriormente ha considerado esta posibilidad. El esquema de compresión de volumen basado en Wavelets para la visualización remota, es una propuesta para compresión que tiene en cuenta la función de transferencia. Permite la inspección de modelos de volumen complejos con máximos niveles de detalles en regiones de interés seleccionados. El rendering ejecuta un ray-casting adaptado a modelos con regiones de interés orientado a la GPU en el cliente con una cantidad de información muy limitada que se envía por la red. La otra contribución de esta tesis es la implementación de un esquema para la exploración remota de modelos volumétricos mediante Gradient Octrees. Esta técnica codifica de manera eficiente datos de volumen mientras garantiza visualizaciones de alta calidad con funciones de transferencias predefinidas en un determinado conjunto. La actual implementación permite codificiar hasta 10 materiales diferentes en los datos de Volumen. Gradient Octrees es una técnica multi-resolución, permite la transmisión progresiva y evita los cálculos del gradiente en el dispositivo cliente. En efecto, esta aproximación codifica gradientes previamente calculados para reducir el coste de los cálculos en la GPU del cliente y garantizar el ray-casting con iluminación en la GPU del dispositivo. En comparación con las propuestas estudiadas la pérdida de la calidad visual en los Gradient Octrees es mínima. La estructura del octree es compacta, compuesta de un pequeño vector de volumen y un conjunto de vectores de texturas codificadas, que utilizan solo 1 bit por nodo del octree. El esquema soporta además secciones planas de volumen que contienen información de alta resolución, además de la extrusión de estructuras en los modelos visualizados

Der volle Inhalt der QuelleVisualization of volumetric datasets is common in many fields and has been an active area of research in the past two decades. In spite of developments in volume visualization techniques, interacting with large datasets still demands research efforts due to perceptual and performance issues. The support of graphics hardware for texture-based visualization allows efficient implementation of rendering techniques that can be combined with interactive sculpting tools to enable interactive inspection of 3D datasets. Many studies regarding performance optimization of sculpting tools have been reported, but very few are concerned with the interaction techniques employed. The purpose of this work is the development of interactive, intuitive, and easy-to-use sculpting tools. Initially, a review of the main techniques for direct volume visualization and sculpting is presented. The best solution that guarantees the required interaction is highlighted. Afterwards, in order to identify the most user-friendly interaction technique for volume sculpting, several interaction techniques, metaphors and taxonomies are presented. Based on that, this work presents the development of three generic sculpting tools implemented using two different interaction metaphors, which are often used by users of 3D applications: virtual pointer and virtual hand. Interactive rates for these sculpting tools are obtained by running special fragment programs on the graphics hardware which specify regions within the volume to be discarded from rendering based on geometric predicates. After development, the performance, precision and user preference of the sculpting tools were evaluated to compare the interaction metaphors. Afterward, the tools were evaluated by comparing the use of a 3D mouse against a conventional wheel mouse for guiding volume and tools manipulation. Two-handed input was also tested with both types of mouse. The results from the evaluation experiments are presented and discussed.

Der volle Inhalt der QuelleDirect volume rendering techniques are used to visualize and explore large scalar volumes. Volume data can be acquired from many sources including medical diagnoses scanners, remote sensing radars or even computer-aided scientific simulations. A key issue in volume rendering is the specification of Transfer Functions (TFs) which assign color and opacity to the scalar values which comprise the volume. These functions are important to the exhibition of features and objects of interest from the volume, but their specification is not trivial or intuitive. Traditional approaches allow the manual editing of a graphic plot with control points representing the TF being applied to the volume. However, these techniques lead the user to an unintuitive trial and error task, which is time-consuming. It is also considered that automatic methods that exclude the user from the process should be avoided, since the user must have some control of the visualization process. This work presents a semi-automatic and interactive tool to assist the user in the specification of color and opacity TFs. The proposed tool has two levels of user interaction. The first level presents to the user several candidate TFs rendered as 3D thumbnails, following the method known as Design Galleries (MARKS et al., 1997). Techniques are applied to reduce the scope of the candidate functions to a more reasonable one. It is also possible to further refine these functions at this level. In the second level is permitted to define and edit colors in the chosen TF, and refine this function if desired. One of the objectives of this work is to allow users to deal with different aspects of TF specification, which is generally dependent of the application or the dataset being visualized. To render the volume, the programmability of the current generation of graphics hardware is explored, as well as the features of texture mapping in order to achieve real time interaction. The tool is applied to medical and synthetic datasets, but the main objective is to propose a general-purpose tool to specify TFs without the need for an explicit mapping from the user.
