Interactive Out-Of-Core Visualization of Large Polygonal Datasets

开发任意大数据集的交互式可视化系统是计算机图形学中的一个基本挑战。我们建议建立一个可视化系统，能够在交互式帧率和各种硬件配置下处理任意大的多边形数据集。系统将根据可视化管道的每个阶段的性能调整图像的质量和帧率。在高端设备上，该系统将以实时帧率提供高分辨率图像，而在低端设备（如pda）上，该系统将以较慢的帧率（尽管是交互式的）提供较小的图像。为了在一系列设备上实现这种可伸缩的性能，我们将开发有效地将可视化需求与可用硬件资源解耦的技术。大型数据集的交互式可视化在许多领域都有应用。此类数据集的示例包括用于制造的计算机辅助设计（CAD）模型（例如，波音777），用于灾难模拟和分析的现实环境模型，以及科学模拟的结果（例如，环境建模）。因为大多数这些数据都被表示为三角形的集合，所以多边形数据集的可视化是一个特别重要的问题。使用这项技术，最终用户将能够与来自办公室或现场的大型3D数据的复杂可视化进行交互。

Developing systems for interactive visualization of arbitrarily large datasets is a fundamental challenge in computer graphics. We propose to build a visualization system capable of processing arbitrarily large polygonal datasets at interactive frame rates and on a wide range of hardware configurations. The system will adjust the quality of the images and the frame rate depending on the performance of each stage of the visualization pipeline. On high-end devices, the system will deliver high-resolution images at real-time frame rates, while on lower-end devices (e.g., PDAs), the system will deliver smaller images at slower (albeit interactive) frame rates. To achieve this scalable performance over a spectrum of devices, we will develop techniques that effectively decouple the visualization requirements from the available hardware resources.Interactive visualization of large datasets has applications in many areas. Examples of such datasets include computer-aided design (CAD) models for manufacturing (e.g., Boeing's 777), models of real-world environments for disaster simulation and analysis, and results of scientific simulations (e.g., environmental modeling). Because most of these data are represented as collections of triangles, visualizing polygonal datasets is a particularly important problem. Using this technology, end-users will be able to interact with complex visualizations of large 3D data from the office or on the field.
