In this paper we present an approach for realistic modeling of surface mesostructure and efficient rendering of the associated visual effects under both local and global illumination.
本文我们将讨论表面的细节结构建模技术和几何细节在局部和全局光照下的实时渲染技术。
Local B-spline surface designing strategy, a surface coincided technology, is proposed entirely originated from practical requirements in reverse engineering CAD modeling.
样条曲面的局部设计是完全根据反求工程CAD建模的实际需求而提出的一种局部区域曲面设计方案。
Meanwhile, it is required that the free-form surface modeling must be able to change the freedom of local and meet all kinds of design requirements.
同时，要求自由曲面的造型必需能够局部地自由加以变更，使其符合各式设计需求。
The local fitting method is a common method of measure and geometric modeling systems for complicated curved surface because of its mathematical model the same as that of current CAD system.
局部拟合因其具有与通用CAD系统相同的数学模型，所以它是复杂曲面测量几何造型系统的常用方法。
