摘要
几何造型是计算机图形学的重要研究内容,CAD/CAM的核心技术。现行的许多造型系统仅限于造型二次曲面及旋转曲面,没有自由曲面造型能力。本文研究的自由畸变方法,很容易扩展这些系统的自由曲面造型功能,该方法已成功地用于扩展MOVIE.BYU系统的自由曲面造型功能。
Geometry modeling is an important research field of computer graphics, and key technique in CAD/CAM. Many modeling systems existing today don't have ability to model free-form surface, and the free-form deformation studied by this paper can be used to extend above ability easily. The algorithm has been successfully used to establish free-form surface modeling of MOVIE.BYU.
