| 摘 要： | 任意８节点六面体单元是有限元分析中常见、且有效的体单元。为了有效地实现对任意六面体剖分结构的结果可视化，提出了基于体单元节点相关性的等值面构造算法，可简捷地确定出等值面的位置，进而得出任意剖面上的等值线，该等值面构造算法突破了以往算法中受规则立方体单元的限制，而且简单可行、实用可靠。

| Abstract: | Arbitrary 8 nodes hexahedron elements are used widely and effectively in FEM. In order to realize the volume data visualization of the arbitrarily tessellated hexahedron elements, a new algorithm of iso surface construction is presented based on the coherence of element nodes. It is easy to determine the position where the iso surface intersects with the hexahedron elements. And then the iso line on the arbitrary section can be displayed. This iso surface constructing algorithm overrides the restrictions that are imposed by regular cubes. It is simple, useful and reliable. |
