The goal of this project is to improve robustness, efficiency and quality of nonlinear, curved geometry and higher-order elements by developing:tight bounds for nonlinear geometry in terms of control structures -- crucial for stable and fast rendering, robust intersection testing, coarse approximation, hierarchical approximation; localized-hierarchy and moment-preserving modeling in a NURBS-compatible framework -- needed for interactive exploratory design and animation; new tools, functionals and an experimental setup for improving surface quality. Software dissemination will concentrate on small packages, acknowledging the fact that many open systems with plug-in capability exist. The research activity will be complemented by structuring and developing the graphics and computer geometry curriculum at the University of Florida both at the bachelors and the PhD-level.

该项目的目标是通过发展以下方面来提高非线性、曲线几何和高阶元素的稳健性、效率和质量：非线性几何在控制结构方面的严格界限-这对稳定和快速绘制、稳健的相交测试、粗略近似、分层近似至关重要;在一个与CIMS兼容的框架中的局部化层次和矩保持建模-这是交互式探索设计和动画所需要的;新的工具，功能和实验设置，以提高表面质量。软件的传播将集中于小的软件包，承认存在许多具有插件能力的开放系统。研究活动将通过构建和开发图形和计算机几何课程在佛罗里达大学在学士和博士水平的补充。
