摘　　要：按点－ 线－ 面的层次数据结构，选取几种有代表性的曲线曲面，实现了三维复杂外形的表面描述。采用曲面到平面的保形变换，在平面内由阵面推进法自动生成三角形网格。Based on a point line patch hierarchical data structure, three dimensional complex geometries are described by several typical kinds of surface patches. A 3D surface patch is first mapped to a 2D segment, then triangulated using a 2D grid generator based on the advancing front method, and finally mapped back to the original 3D shape. Examples include a reentry space capsule,the ‘Columbia’ space shuttle, a missile and a civil aircraft, which demonstrate the flexibility and robust of present method.
