U.S.-China Cooperative Research: Cooperative Geometric Modeling

9722728程该奖项支持为期三年的工程设计几何建模项目。该项目是肯塔基大学和清华大学的合作项目，旨在提升几何建模的最新水平，通过参与研究项目让美国学生体验中国，并改进通过万维网进行远程合作的方法。该提案为DDM 9400823增加了国际层面。几何设计与造型是计算机辅助设计领域的一个重要研究和发展方向。汽车、航空航天和造船工业在很大程度上依赖于这一领域开发的许多技术的应用。然而，工程设计的几何建模是一个困难的领域，许多问题仍然悬而未决，阻碍了计算机在工程设计中的应用。对新的计算和可视化技术的研究寻求促进进一步的建模和设计。该项目建议开发和提供支持这种方法的CAD/CAM软件系统。这需要为面向对象的几何造型工具包的许多组件开发网络CAD/CAM接口和协作设计范例。这些应用程序将作为独立于平台的应用程序实现，可通过Web从任何地方访问。项目人员将包括清华大学计算机辅助设计中心的教职员工级别的科学家，该中心是世界上最大的几何建模研究团队之一。美国的参与者包括加州大学伯克利分校和肯塔基大学的教职员工。肯塔基大学每年将有两名本科生参加，他们将从计算机科学和工程领域代表性不足的群体中挑选出来。学生将全面参与研究，包括对清华大学、北京、中国的研究访问。中方支持由国家自然科学基金提供。该项目得到了美国-中国基础科学合作议定书的支持。

9722728 Cheng This award supports a three-year program in geometric modeling for engineering design. A cooperative project between the University of Kentucky and Tsinghua University, the program seeks to advance the state of the art in geometric modeling, give U.S. students experience in China through participation in the research project, and improve methods for collaboration remotely via the world wide web. The proposal adds an international dimension to DDM 9400823. Geometric design and modeling is a major research and development area in computer aided design. The automobile, aerospace, and shipbuilding industries rely heavily on applications of many techniques developed in this area. Geometric modeling for engineering design, however, is a difficult field and many unanswered question remain that inhibit use of computers in engineering design. Research on new computational and visualization techniques seeks to facilitate further modeling and design. This project proposes to develop and deliver CAD/CAM software systems which support such methodologies. This requires development of network CAD/CAM interfaces and collaborative design paradigms for a number of components of an object- oriented geometric modeling tool kit. These will be implemented as platform-independent applications which can be accessed from anywhere over the Web. Project personnel will include faculty level scientists from Tsinghua University's Computer Aided Design Center which is one of the largest geometric modeling research teams in the world. US participants include faculty of the University of California, Berkeley, and the University of Kentucky. Two undergraduate students from the University of Kentucky will participate each year, and will be chosen from groups underrepresented in computer science and engineering fields. The students will participate in the research fully, including in research visits to Tsinghua University, Beijing, China. Support on the Chinese side is provided by the National Natural Science Foundation. This project is supported under the US-China Protocol on Cooperation in Basic Sciences.
