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.

高级科学分析和计算中的表面丰富。虚拟环境的基本几何形状，音量数据的等音表面以及合成环境的细分表面是一些示例。表面的有效利用和数据管理需要查询表面档案的能力，以寻找特定的表面形状和特征。该能力的中心是测量两个表面之间距离的有效手段。产生表面的算法的客观比较需要相互或以理想的方式对表面进行类似的精确和定量度量。该项目将开发一种用于计算两个表面之间距离的新方法。它还将开发有效的基本技术和算法，这些技术和算法将在搜索表面数据库和比较表面上的算法的搜索领域的日常使用中使用。
