CAREER: Integrated Environment for Interactive Rendering of Large-Scale Solid Models

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。这项研究将产生显著加快在当前图形系统上渲染表面模型的技术。重点将放在处理和渲染大型模型方面的新算法改进上。使用解析表面和其他大型模型的高阶表示的有效性也将被研究。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。本研究将利用和改进这些研究成果。具体地说，它将导致以下结果：-在线细分成少量三角形的更高阶和分层表示，基于用户的位置高效的表面可见性处理-动态变化表面的交互式渲染-改进的表面采样以生成有纹理的多边形近似-无需用户输入即可调整渲染速度和质量的可配置系统-随可用计算资源和模型大小很好地扩展的算法-允许各种技术互操作并导致最先进水平的综合改进的统一框架该项目还包括设计和安装新的计算机图形学课程和约翰霍普金斯大学计算机科学系的实验室。计划在教室和实验室之间进行重大互动。Usenet和万维网将被广泛用于加强课堂教学。此外，还将组织研讨会和非正式会议，讨论计算机制图方面的研究。

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.
