This research is in the area of geometrical modelling. It is organized into three categories of projects. The largest is a collaborative effort centered on a VLSI raycasting engine that should improve dramatically the performance of solid modelling systems. An NSF-funded team at Duke University will supply experimental prototypes of the special purpose computer; Cornell will create and operate appropriate test beds for production automation applications and will study a range of issues bearing on the integration of the computer into systems and on new applications and extensions of the technology. A second category of theory-and-algorithm projects will emphasize research on active-zone algorithms, spatial sweeping domain extensions and other geometric modelling problems. The third category of projects is exploratory in character and includes the management of complexity and modelling support for mechanical design. The principal investigator is a capable researcher and has done pioneering work in solid modelling. The funding of this project will make possible the testing of the raycasting machine designed at Duke University by an expert user, as well as providing the environment for new research in solid modelling. Approximately half of the project relates to the testing and evaluating the performance of the ray- casting machine and is funded by the Experimental Systems Program, Division of Microelectronic Information Processing Systems (MIPS), and the other half of the project relates to new work in solid modelling and is funded by the Division of Design, Manufacturing, and Computer- Integrated Engineering (DMCE).

这项研究是在几何建模领域。 其组织 分为三类项目。 最大的是协作 努力集中在一个超大规模集成电路光线投射引擎，应该改善 显著提高了实体建模系统的性能。 NSF资助的 杜克大学的一个研究小组将提供 特殊用途计算机;康奈尔大学将创建和操作适当的 生产自动化应用的试验台，并将研究一系列 与计算机集成到系统中有关的问题， 新的应用和技术的扩展。 第二 理论和算法类项目将重点研究 活动区算法、空间扫描域扩展和其他 几何建模问题。 第三类项目是 探索性的，包括复杂性的管理， 为机械设计提供建模支持。 主要研究者是一位有能力的研究人员，并且已经完成了 在实体建模方面的开创性工作。 该项目的资金将 使杜克设计的光线投射机的测试成为可能 大学由专家用户，以及提供环境， 在实体建模方面的新研究。 项目的一半左右 涉及射线性能的测试和评价， 铸造机，并由实验系统计划资助， 微电子信息处理系统司（MIPS） 该项目的另一半与实体建模方面的新工作有关 由设计、制造和计算机部资助， 集成工程（DMCE）。
