Surfaces abound in advanced scientific analysis and computing. The basic geometry of virtual environments, the isosurfaces of volume data, and the subdivision surfaces of synthetic environments are some examples. Effective utilization and data management of surfaces requires the ability to query archives of surfaces to look for particular surface shapes and features. Central to this capability is an efficient means to measure the distance between two surfaces. The objective comparison of algorithms that produce surfaces requires a similar precise and quantitative measure of the surfaces with each other or with an ideal. This project will develop a new methodology for computing the distance between two surfaces. It will also develop efficient basic techniques and algorithms that will bring this technology into everyday use in areas of searching databases of surfaces and comparing algorithms on surfaces.

表面充满了先进的科学分析和计算。虚拟环境的基本几何形状、体数据的等值面以及合成环境的细分曲面都是一些例子。表面的有效利用和数据管理需要能够查询表面档案以查找特定的表面形状和特征。此功能的核心是一种测量两个表面之间距离的有效方法。生成曲面的算法的客观比较需要对各个曲面或与理想曲面进行类似的精确和定量测量。该项目将开发一种计算两个表面之间距离的新方法。它还将开发高效的基础技术和算法，将该技术应用于搜索表面数据库和比较表面算法领域的日常使用。
