CISE Research Instrumentation: Interactive Modeling and Visualization of Complex Environments

小行星9320390 该奖项用于购买最先进的高性能图形工作站，该工作站将致力于支持计算机和信息科学与工程的研究。 该设备将用于以下交互式建模和可视化研究项目：（1）几何设计优化，（2）多分辨率几何，（3）受控精度逼真图像合成，（4）计算机生成的插图，（5）透视界面。 这些项目的动机是一个共同的主题：开发用于探索极其复杂的环境和数据集的工具，例如在工程设计，医学成像和物理模拟中遇到的那些。 这些项目结合了两种强大的技术：多分辨率分析和交互性。 多分辨率分析提供了一个数学框架，用于表示数据不同区域的不同详细程度。 交互性允许用户动态选择需要详细表示的数据区域。 总之，这些技术允许显著的性能增益，因为在大多数应用中，仅在整个数据集的一小部分上需要高保真度。 即使有了这些算法性能增益，交互式图形系统仍然需要快速CPU，与高性能图形硬件紧密耦合，以便操纵多分辨率表示，以及真实的更新视觉显示。 预计在未来五到十年内，这种硬件将相对便宜和常见。 然而，由于实时交互和批处理模式仿真之间存在着公认的质的差异，因此试图在功能较弱的硬件上模拟不久的将来的交互方法基本上是徒劳的。 因此，获得高性能的图形工作站至关重要。 *** 阿莱克斯 @ j E B ALHLP @ j 小行星9320390 该奖项是为购买一个国家的最先进的高性能图形工作站，这将是ded 4 Z \ _ 一 / 4 $ $ $ $ G 4 4 倍 Helvetica符号 芝加哥 Times New Roman Arial 5罗马新R ZapfDingbats Palatino 希腊 GenMath 数学气象 MT Extra " 9 e9 e : 德罗斯/华盛顿 马克·珀维斯

9320390 DeRose This award is for the purchase of a state-of-the-art high-performance graphics workstation which will be dedicated to support research in computer and information science and engineering. The equipment will be used for the following research projects in interactive modeling and visualization: (1) Geometric design optimization, (2) Multiresolution geometry, (3) Controlled-precision photorealistic image synthesis, (4) Computer-generated illustration, and (5) The see-through interface. These projects are motivated by a common theme: to develop tools for exploring extremely complex environments and datasets such as those encountered in engineering design, medical imaging, and physical simulation. The projects couple two powerful techniques: multiresolution analysis and interactivity. Multiresolution analysis provides a mathematical framework for representing varying levels of detail in different regions of the data. Interactivity allows a user to dynamically choose the regions of the data where a detailed representation is required. Together, these techniques allow substantial performance gains, since in most applications high fidelity is required over only a small portion of the overall dataset. Even with these algorithmic performance gains, the interactive graphical systems will still require fast CPUs, tightly coupled with high-performance graphics hardware, in order to manipulate the multiresolution representations, as well as to update the visual display in real time. It is expected that such hardware will be relatively inexpensive and commonplace in the next five to ten years. However, since there is a well-recognized qualitative difference between real-time interactivity and batch-mode simulation, attempting to simulate the interactive methods of the near future on less-powerful hardware is essentially futile. It is, therefore, essential to acquire a high-performance graphics workstation. *** TERMINALEXE @ j E B TERMINALHLP @ j 9320390 DeRose This award is for the purchase of a state-of-the-art high-performance graphics workstation which will be ded 4 Z \ _ a / 4 $ $ $ $ G 4 4 Times Symbol " Helvetica Chicago Times New Roman & Arial 5 Courier New R ZapfDingbats Palatino Greek GenMath MathMeteor MT Extra " 9 e9 e : DeRose/Washington Mark Purvis Mark Purvis
