| 摘 要： | 针对３维非结构化网格数据场出现的各种网格单元，设计了相应的直边４面体化剖分方案，并在此基础上提出了一种关于非结构化网格数据场的切片可视化方法，简化了切平面与网格单元间相交多边形的计算，保证了各相交多边形的自然合法性．实践表明：所用的直边４面体化剖分方案同样适用于等值面构造技术

| Abstract: | This paper presents tetrahedrization partition methods for various cells used in 3D unstructured grid data, on the basis of which a slice visualization method for unstructured grid data is given, thus making the computation of the intersection between the cutting plane and cells very simple, and automatically guaranteing the reasonableness of intersection polygons. The above partition can also be used in the isosurface construction technique for such data. |
