As scientific data becomes larger and more complex, the problem of presenting data effectively is joined by another, potentially more difficult one - how to extract presentable data from the flood of raw information. This problem is equally difficult for results from large simulations and data from high-resolution instruments. Thus, the field of scientific visualization becomes intimately tied to more traditional studies of data analysis, including image processing, pattern recognition, artificial intelligence, and computer vision. However, in contrast to those fields, visualization explicitly includes the user in the process of filtering, extracting, and rendering meaningful data. The goal of this project is to make level-set modeling - a useful but computationally expensive visualization technique - interactive for use in 3-D visualization of biological data sets.Technically, the project has three components. The first is the design and implementation of a hardware and software system for interactive level-set surface model computation and display. This system will use off-the-shelf PC hardware and graphics boards and new algorithms and software to reach its interactivity goals. The second component will create the human-computer interface that allows users to interact with the level-set models. This will require mapping user input onto the mathematical descriptions controlling surface motion and deformation in the models. Finally, the third component will be the application of the techniques to visualize large biological data sets by researchers in this project.This is a collaborative project between California Institute of Technology and the University of Utah.

随着科学数据变得更大且越来越复杂，有效地呈现数据的问题与另一个更困难的问题（如何从原始信息的洪水中提取出现的数据）结合在一起。对于来自高分辨率工具的大型模拟和数据结果，此问题同样困难。因此，科学可视化领域与更传统的数据分析研究密切相关，包括图像处理，模式识别，人工智能和计算机视觉。但是，与这些字段相反，可视化明确包括在过滤，提取和渲染有意义的数据的过程中使用用户。该项目的目的是使级别建模 - 一种有用但计算上昂贵的可视化技术 - 用于3D可视化生物数据集的交互式。技术上，该项目具有三个组件。首先是用于交互式级别表面模型计算和显示的硬件和软件系统的设计和实现。该系统将使用现成的PC硬件和图形板以及新算法和软件来达到其交互性​​目标。第二个组件将创建人类计算机接口，该界面允许用户与级别集合模型进行交互。这将需要将用户输入映射到控制模型中表面运动和变形的数学描述上。最后，第三部分将是该技术在该项目中可视化大型生物数据集的应用。这是加利福尼亚技术学院与犹他大学之间的合作项目。
