10th Annual ieee symposium on Information visualization (InfoVis 2004)

作者： Artero, AO de Oliveira, MCF Levkowitz, H Univ Sao Paulo Dept Comp Sci Sao Paulo Brazil

ISBN: (纸本)0780387791

The one-to-one strategy of mapping each single data item into a graphical marker adopted in many visualization techniques has limited usefulness when the number of records and/or the dimensionality of the data set are very high. In this situation, the strong overlapping of graphical markers severely hampers the user's ability to identify patterns in the data from its visual representation. We tackle this problem here with a strategy that computes frequency or density information from the data set, and uses such information in parallel Coordinates visualizations to filter out the information to be presented to the user, thus reducing visual clutter and allowing the analyst to observe relevant patterns in the data. The algorithms to construct such visualizations, and the interaction mechanisms supported, inspired by traditional image processing techniques such as grayscale manipulation and thresholding are also presented. We also illustrate how such algorithms can assist users to effectively identify clusters in very noisy large data sets.

Proceedings - 18th International parallel and Distributed Processing symposium, IPDPS 2004 (Abstracts and CD-ROM)

The tremendous amount of data generated by large-scale, parallel scientific and engineering simulations make the analysis and archiving of this data difficult. To address this problem, in previous work, we developed an efficient archival scheme based on the functional representation of simulation data - this approximation scheme can significantly reduce storage requirements. However, common visualization tools such as the marching cubes algorithm for isosurface generation cannot be directly applied with this data representation. Thus, in this paper we propose a new, efficient isosurface visualization algorithm that takes full advantage of the functional approximation of simulation data. This method is fundamentally different from the marching cubes approach in that the visualization of isosurface is achieved through the solution of sets of ordinary differential equations. We present computational results detailing the effectiveness of this new approach for a simulation modeling the fluid dynamics of a turbulent reacting flow. The results demonstrate that the method is efficient in a parallel environment and represents a promising approach for the visualization of isosurface in simulation data from large-scale scientific applications.

In this study, we explore a novel approach for visualizing the energetic turbulent structures in a flow field. The flow field is generated by a direct numerical simulation (DNS) of a stratified turbulent shear layer instigated by the Kelvin-Helmholtz instability. The use of so-called structure-based tensors combined with volume rendering seems to be a very promising tool to gain new insight into the dynamically most important part of the turbulence. Rendering of these tensors depicts the large-scale structures that carry most of the turbulence energy. This is in distinct contrast to traditional methods based on derivatives of the velocity field, such as those based on the velocity gradient tensor and vorticity. These methods only capture the smaller-scale structures of the flow. Traditionally, statistical measures are used to handle the enormous amount of data generated by DNS, whereby a lot of detailed information is inevitably lost. The rapid increase in computer performance combined with advanced visualization techniques makes it possible to use a non-statistical or deterministical approach to study the kinematic and dynamic properties of turbulent flows. This paper presents a promising first attempt to render structure-based tensors to see how faithfully they can describe the large-scale structures in a stratified turbulent shear flow. ©2004 ieee.

3D ROAM for scalable volume visualization

The 2D real time optimally adapting meshes (ROAM) algorithm has had wide success in the field of terrain visualization, because of its efficient error-controlling properties. In this paper, we propose a generalization of ROAM in 3D suitable for scalable volume visualization. Therefore, we perform a straightforward 2D/3D analogy, replacing the triangle of 2D ROAM by its 3D equivalent, the tetrahedron. Although work in the field of hierarchical tetrahedral meshes was widely undertaken, the produced meshes were not used for volumetric rendering purposes. We explain how to compute a bounded error inside the tetrahedron to build a hierarchical tetrahedral mesh and how to refine this mesh in real time to adapt it to the viewing conditions. We further show how to achieve cell sorting in linear time, thus yielding real time view-dependent display of the volumetric object. We present examples of large volume data sets and compare our approach with a similar one. Our results outline the high quality and computational efficiency of our approach. ©2004 ieee.

JuxtaView is a cluster-based application for viewing ultra-high-resolution images on scalable tiled displays. We present in JuxtaView, a new parallel computing and distributed memory approach for out-of-core montage visualization, using LambdaRAM, a software-based network-level cache system. The ultimate goal of JuxtaView is to enable a user to interactively roam through potentially terabytes of distributed. spatially referenced image data such as those from electron microscopes, satellites and aerial photographs. In working towards this goal, we describe our first prototype implemented over a local area network, where the image is distributed using LambdaRAM, on the memory of all nodes of a PC cluster driving a tiled display wall. Aggressive pre-fetching schemes employed by LambdaRAM help to reduce latency involved in remote memory access.. We compare LambdaRAM with a more traditional memory-mapped file approach for out-of-core visualization.

We present a method for ray casting curved-quadratic elements in 3D. The advantages of this approach is that a curved element can be directly visualized. Conventionally, higher-order elements are tessellated with several linear elements so that standard visualization techniques can be applied to the linear elements. Our method primarily focuses on how to find an approximation to the intersection between a ray and a curved-quadratic element. Once this approximation is found, conventional accumulation and color mapping techniques can be applied to the approximation to produce a volumetric visualization of the element. A cutting plane implementation is also shown that leverages the ray casting technique. © The Eurographics Association 2004.

ieee symposium on Volume visualization and graphics

Hardware-accelerated image composition for sort-last parallel rendering has received increasing attention as an effective solution to increased performance demands brought about by the recent advances in commodity graphics accelerators. So far, several different hardware solutions for alpha and depth compositing have been proposed and a few of them have become commercially available. They share impressive compositing speed and high scalability. However, the cost makes it prohibitively expensive to build a large visualization system. In this paper, we used a hardware image compositor marketed by Mitsubishi Precision Co., Ltd. (MPC) which is now available as an independent device enabling the building of our own visualization cluster. This device is based on binary compositing tree architecture, and the scalable cascade interconnection makes it possible to build a large visualization system. However, we focused on a minimal configuration PC cluster using only one compositing device while taking cost into consideration. In order to emulate this cascade interconnection of MPC compositors, we propose and evaluate the hybrid hardware-assisted image composition method which uses the OpenGL alpha blending capability of the graphics boards for assisting the hardware image composition process. Preliminary experiments show that the use of graphics boards diminished the performance degradation when using an emulation based on image feedback through available interconnection network. We found that this proposed method becomes an important alternative for providing high performance image composition at a reasonable cost.

Texture-encoded tetrahedral strips

Texture-encoded tetrahedral strips

ieee symposium on Volume visualization and graphics

作者： M. Weiler P.N. Mallon M. Kraus T. Ertl University of Stuttgart Germany University of Santiago de Compostela Spain Purdue University USA

The use of triangle strips is a common method to compactly store and efficiently render large polygonal meshes. The advantages of triangle stripification also apply to tetrahedral meshes; therefore, tetrahedral strips are an attractive data structure for storing and volume rendering tetrahedral meshes as noted in several publications. However, tetrahedral strips are still not supported by current graphics hardware. In this paper, we present the first system to take advantage of tetrahedral strips in off-the-shelf graphics hardware. This is achieved by encoding tetrahedral strips in texture maps and rendering them with the help of a ray casting algorithm running solely on the graphics chip. Our data structure supports sequential and generalized tetrahedral strips by including a small amount of adjacency information, which allows us to access all face neighbors in constant time. Utilizing these texture-encoded tetrahedral strips, our enhanced graphics-hardware-based volume ray casting algorithm for tetrahedral meshes is capable of handling large data sets. Additional improvements presented in this paper include support for multiple ray traversal steps in one rendering pass and the intrinsic support for non-convex meshes using a rendering technique similar to depth peeling.
