Interactive rendering is crucial to virtual design and prototyping of large engineering models. This research will produce techniques to significantly speed up the rendering of surface models on current graphics systems. The emphasis will be on novel algorithmic improvements in processing and rendering of large models. The effectiveness of using analytic surfaces and other higher order representations of large models will also be investigated. Such representations contain more information than polygonal representations, but take less space to store. Recent improvements in efficient tessellation and rendering of parametric surfaces have opened up new possibilities for speeding up the rendering of large surface models. This research will use and improve these results. In particular, it will result in the following: - Higher-order and hierarchical representations tessellated on- line into a small number of triangles, based on the user's position - Efficient visibility processing of surfaces - Interactive rendering of dynamically changing surfaces - Improved sampling of surfaces for the generation of textured polygonal approximations - Configurable system that adjusts rendering speed and quality without requiring user input - Algorithms that scale well with both available computing resources and model size - A unified framework that allows various techniques to inter-operate and results in combined improvement in the state of the art The project also includes design and installation of new computer graphics courses and laboratories in the computer science department at the Johns Hopkins University. Significant interactions between the classrooms and laboratories are planned. The usenet and the world wide web will be widely used to augment the classroom teaching. In addition, seminars and informal meetings will be organized to discuss research in computer graphics.

交互式渲染对于大型工程模型的虚拟设计和原型制作至关重要。这项研究将产生显着加快当前图形系统上表面模型渲染速度的技术。重点将放在大型模型处理和渲染方面的新颖算法改进。 还将研究使用大型模型的解析曲面和其他高阶表示的有效性。此类表示比多边形表示包含更多信息，但存储空间更少。最近在参数化曲面的高效细分和渲染方面的改进为加速大型曲面模型的渲染开辟了新的可能性。本研究将利用并改进这些结果。特别是，它将产生以下结果： - 基于用户位置，将高阶和分层表示在线细分为少量三角形 - 表面的高效可见性处理 - 动态变化表面的交互式渲染 - 改进表面采样以生成纹理多边形近似 - 可配置系统，无需用户输入即可调整渲染速度和质量 - 算法 与可用的计算资源和模型大小良好地扩展 - 一个统一的框架，允许各种技术互操作并导致最先进的综合改进该项目还包括在约翰霍普金斯大学计算机科学系设计和安装新的计算机图形课程和实验室。计划在教室和实验室之间进行重要的互动。 新闻组和万维网将被广泛使用来增强课堂教学。此外，还将组织研讨会和非正式会议来讨论计算机图形学的研究。
