Workshop on Geometric Modeling for Computer-Aided Product Realization; Rensselaerville, New York; September 18-22, 1988

本提案要求资助一个研讨会，以确定，记录和传播在计算机辅助设计（CAD）的广泛领域中应用于产品设计和制造的几何建模的有前途的研究方向。几何建模是工程设计和制造的核心。近年来，几何建模需求发生了巨大变化。CAD系统的几何方面已经从线形几何发展到实体模型，它允许自动三维彩色阴影图形和自动分析。这一进展改善了设计-制造过程的详细设计部分，但对初步设计和概念设计过程几乎没有帮助。例如，实体建模研究的现状还没有解决设计者可以推理的几何表示问题。几何（形式）特征和设计特征总体上显示了对这个“推理”问题的研究前景。需要做很多工作来制定问题，并关注最有希望的计算机表示的几何表示。这些研究问题的成功解决将有助于在概念设计、生命周期需求设计以及并行产品和工艺设计等有前途的新领域中建立技术进步的框架。这一领域的研究进展将有助于改变未来的设计方式。本次研讨会的作用是将注意力集中在几何设计的基本研究方向上，这将使这些新的设计过程得以实现。

This proposal requests funding for a workshop to identify, record and disseminate promising research directions in geometric modeling as applied in the broad area of computer- aided design (CAD) for the design and manufacture of products. Geometric modeling is central to engineering design and manufacturing. In recent years, geometric modeling needs have changed dramatically. The geometric aspects of CAD systems have evolved from line geometry to solid models which allow automated three dimensional color shaded graphics and automated analysis. This progress has improved the detailed design portion of the design-manufacturing process, but has done little for preliminary and conceptual design process. For example, the present state of solid modeling research has not resolved the question of geometric representations about which the designer can reason. Geometric (form) features and design features in general show promise in making inroads into this "reasoning" question. Much work needs to be done to formulate the issues and focus on the most promising geometric representations for computer representation. Successful resolution of these research questions will contribute to the framework for technological progress in the promising new areas of conceptual design, design for life cycle requirements, and concurrent product and process design. Research progress in this area will contribute to changing the way design will be done in the future. The role of this workshop is to focus attention on the essential research directions in geometric design which will enable the realization of such new design processes.
