Download or read book Interactive GPU based Visualization of Large Dynamic Particle Data written by Martin Falk and published by Morgan & Claypool Publishers. This book was released on 2016-10-02 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prevalent types of data in scientific visualization are volumetric data, vector field data, and particle-based data. Particle data typically originates from measurements and simulations in various fields, such as life sciences or physics. The particles are often visualized directly, that is, by simple representants like spheres. Interactive rendering facilitates the exploration and visual analysis of the data. With increasing data set sizes in terms of particle numbers, interactive high-quality visualization is a challenging task. This is especially true for dynamic data or abstract representations that are based on the raw particle data. This book covers direct particle visualization using simple glyphs as well as abstractions that are application-driven such as clustering and aggregation. It targets visualization researchers and developers who are interested in visualization techniques for large, dynamic particle-based data. Its explanations focus on GPU-accelerated algorithms for high-performance rendering and data processing that run in real-time on modern desktop hardware. Consequently, the implementation of said algorithms and the required data structures to make use of the capabilities of modern graphics APIs are discussed in detail. Furthermore, it covers GPU-accelerated methods for the generation of application-dependent abstract representations. This includes various representations commonly used in application areas such as structural biology, systems biology, thermodynamics, and astrophysics.

Available in PDF, EPUB and Kindle. Book excerpt: Spatio-temporal data denotes a category of data that contains spatial as well as temporal components. For example, time-series of geo-data, thematic maps that change over time, or tracking data of moving entities can be interpreted as spatio-temporal data. In today's automated world, an increasing number of data sources exist, which constantly generate spatio-temporal data. This includes for example traffic surveillance systems, which gather movement data about human or vehicle movements, remote-sensing systems, which frequently scan our surroundings and produce digital representations of cities and landscapes, as well as sensor networks in different domains, such as logistics, animal behavior study, or climate research. For the analysis of spatio-temporal data, in addition to automatic statistical and data mining methods, exploratory analysis methods are employed, which are based on interactive visualization. These analysis methods let users explore a data set by interactively manipulating a visualization, thereby employing the human cognitive system and knowledge of the users to find patterns and gain insight into the data.

This book was released on 2008-12-17 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: II Challenges in Data Mapping Part II deals with one of the most challenging tasks in Interactive Visualization, mapping and teasing out information from large complex datasets and generating visual representations. This section consists of four chapters. Binh Pham, Alex Streit, and Ross Brown provide a comprehensive requirement analysis of information uncertainty visualizations. They examine the sources of uncertainty, review aspects of its complexity, introduce typical models of uncertainty, and analyze major issues in visualization of uncertainty, from various user and task perspectives. Alfred Inselberg examines challenges in the multivariate data analysis. He explains how relations among multiple variables can be mapped uniquely into ?-space subsets having geometrical properties and introduces Parallel Coordinates meth- ology for the unambiguous visualization and exploration of a multidimensional geometry and multivariate relations. Christiaan Gribble describes two alternative approaches to interactive particle visualization: one targeting desktop systems equipped with programmable graphics hardware and the other targeting moderately sized multicore systems using pack- based ray tracing. Finally, Christof Rezk Salama reviews state-of-the-art strategies for the assignment of visual parameters in scientific visualization systems. He explains the process of mapping abstract data values into visual based on transfer functions, clarifies the terms of pre- and postclassification, and introduces the state-of-the-art user int- faces for the design of transfer functions.

Download or read book GPU Based Techniques for Global Illumination Effects written by Laszlo Szirmay-Kalos and published by Springer Nature. This book was released on 2022-05-31 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents techniques to render photo-realistic images by programming the Graphics Processing Unit (GPU). We discuss effects such as mirror reflections, refractions, caustics, diffuse or glossy indirect illumination, radiosity, single or multiple scattering in participating media, tone reproduction, glow, and depth of field. The book targets game developers, graphics programmers, and also students with some basic understanding of computer graphics algorithms, rendering APIs like Direct3D or OpenGL, and shader programming. In order to make the book self-contained, the most important concepts of local illumination and global illumination rendering, graphics hardware, and Direct3D/HLSL programming are reviewed in the first chapters. After these introductory chapters we warm up with simple methods including shadow and environment mapping, then we move on toward advanced concepts aiming at global illumination rendering. Since it would have been impossible to give a rigorous review of all approaches proposed in this field, we go into the details of just a few methods solving each particular global illumination effect. However, a short discussion of the state of the art and links to the bibliography are also provided to refer the interested reader to techniques that are not detailed in this book. The implementation of the selected methods is also presented in HLSL, and we discuss their observed performance, merits, and disadvantages. In the last chapter, we also review how these techniques can be integrated in an advanced game engine and present case studies of their exploitation in games. Having gone through this book, the reader will have an overview of the state of the art, will be able to apply and improve these techniques, and most importantly, will be capable of developing brand new GPU algorithms.

Download or read book Image Based Visualization written by Christophe Hurter and published by Springer Nature. This book was released on 2022-05-31 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our society has entered a data-driven era, one in which not only are enormous amounts of data being generated daily but there are also growing expectations placed on the analysis of this data. Some data have become simply too large to be displayed and some have too short a lifespan to be handled properly with classical visualization or analysis methods. In order to address these issues, this book explores the potential solutions where we not only visualize data, but also allow users to be able to interact with it. Therefore, this book will focus on two main topics: large dataset visualization and interaction. Graphic cards and their image processing power can leverage large data visualization but they can also be of great interest to support interaction. Therefore, this book will show how to take advantage of graphic card computation power with techniques called GPGPUs (general-purpose computing on graphics processing units). As specific examples, this book details GPGPU usages to produce fast enough visualization to be interactive with improved brushing techniques, fast animations between different data representations, and view simplifications (i.e. static and dynamic bundling techniques). Since data storage and memory limitation is less and less of an issue, we will also present techniques to reduce computation time by using memory as a new tool to solve computationally challenging problems. We will investigate innovative data processing techniques: while classical algorithms are expressed in data space (e.g. computation on geographic locations), we will express them in graphic space (e.g., raster map like a screen composed of pixels). This consists of two steps: (1) a data representation is built using straightforward visualization techniques; and (2) the resulting image undergoes purely graphical transformations using image processing techniques. This type of technique is called image-based visualization. The goal of this book is to explore new computing techniques using image-based techniques to provide efficient visualizations and user interfaces for the exploration of large datasets. This book concentrates on the areas of information visualization, visual analytics, computer graphics, and human-computer interaction. This book opens up a whole field of study, including the scientific validation of these techniques, their limitations, and their generalizations to different types of datasets.
Download or read book Interactive Visualization for Assistance of Needle Based Interventions written by Christian Rieder and published by . This book was released on 2013 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Needle-based interventions are an important part of tumor ablation therapies. Due to their common technical procedure, low complication rate, and low cost, needle-based ablation therapies have become alternatives to surgical resections in clinical practice. To date, the most well-studied and clinically relevant ablation therapy is radiofrequency ablation (RFA) in the liver. However, achieving successful outcomes is a challenging task which depends on a variety of partially unknown reasons. This uncertainty is mirrored by the high local recurrence rates reported in clinical studies. The aim of this PhD thesis is the investigation of interactive visualization methods to support the physician in planning and assessing needle-based interventions, in particular RFA. This work proposes a software workflow designed to guide the physician in plan- ning the intervention in clinical practice. To support the physician with spatial information about pathological structures as well as finding trajectories without harming vitally important tissue, 2D slice and volume visualization techniques for interactive planning of needle-based interventions are presented. A further contribution for planning RFA is the fast approximation of the ablation zone, incorporating the heat-sink effects of blood vessels which decrease thermal ablation. In this approach, weighted distance fields are utilized to calculate the ablation zone within interactive frame rates on the graphics processing unit (GPU). To support the assessment of needle-based interventions such as RFA, an image- processing workflow for automatic alignment of CT images is proposed. Based on segmentation masks of tumor and coagulation, the workflow enables an automatic rigid registration algorithm to perform at least as accurately as experienced medical experts, but in significantly less time. A further contribution is a novel overview visualization as well as a navigation tool, the so-called tumor map. The goal of this method is the combined visualization of the tumor and its surface distance to the coagulation necrosis to support the physician in reliable therapy assessment. The tumor map additionally serves as an interactive tool for intuitive navigation within a 3D volume rendering of the tumor vicinity as well as within familiar 2D viewers. To facilitate the development of highly interactive visualization techniques, a rapid prototyping framework for GPU-based volume rendering is developed as part of this PhD thesis. The framework supports flexible extension and dynamic alteration of the volume rendering configuration. Therefore, a dynamic shader pipeline based on the SuperShader concept allows the user to insert custom shaders at run-time of the prototyping framework.

Download or read book Interactive Data Processing and 3D Visualization of the Solid Earth written by Daniel Patel and published by Springer Nature. This book was released on 2022-02-21 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents works detailing the application of processing and visualization techniques for analyzing the Earth’s subsurface. The topic of the book is interactive data processing and interactive 3D visualization techniques used on subsurface data. Interactive processing of data together with interactive visualization is a powerful combination which has in the recent years become possible due to hardware and algorithm advances in. The combination enables the user to perform interactive exploration and filtering of datasets while simultaneously visualizing the results so that insights can be made immediately. This makes it possible to quickly form hypotheses and draw conclusions. Case studies from the geosciences are not as often presented in the scientific visualization and computer graphics community as e.g., studies on medical, biological or chemical data. This book will give researchers in the field of visualization and computer graphics valuable insight into the open visualization challenges in the geosciences, and how certain problems are currently solved using domain specific processing and visualization techniques. Conversely, readers from the geosciences will gain valuable insight into relevant visualization and interactive processing techniques. Subsurface data has interesting characteristics such as its solid nature, large range of scales and high degree of uncertainty, which makes it challenging to visualize with standard methods. It is also noteworthy that parallel fields of research have taken place in geosciences and in computer graphics, with different terminology when it comes to representing geometry, describing terrains, interpolating data and (example-based) synthesis of data. The domains covered in this book are geology, digital terrains, seismic data, reservoir visualization and CO2 storage. The technologies covered are 3D visualization, visualization of large datasets, 3D modelling, machine learning, virtual reality, seismic interpretation and multidisciplinary collaboration. People within any of these domains and technologies are potential readers of the book.

The book concludes with an outline of successful practical applications of visualization, and future trends in scientific visualization.
Download or read book Hardware Acceleration of Information Visualization Techniques Using the GPU written by Kirk Fernandez and published by . This book was released on 2010 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Information visualization is increasingly being applied as a critical component in scientific research. Increasing data size requires faster processing. This thesis proposes ways of implementing information visualization techniques on the graphics process¬ing unit (GPU) in particular parallel coordinates and treemaps. Each technique is designed to run on either the central processing unit (CPU) or the GPU. The parallel coordinates technique runs on the vertex shader, while treemaps use the fragment shader. The Parallel coordinates have interactive features like brushing, axis reorder¬ing and axis inversion which are provided to examine the data. The programs are run on different computers and the results are compared. It is observed that on computers with low end graphics cards, the program runs faster on the CPU than on the GPU and on computers with high end graphics cards the program runs faster on the GPU than on the CPU.
