| 摘 要： | 为了生成四边形网格的等值线,通过引入虚节点将四边形网格剖分为四个三角形实现对四边形网格上等值线的生成方法避免了等值点的跟踪,但是当网格尺寸太大时,得到的等值线拐点太多,不光滑,本文利用Bezier曲线对等值线进行逼近,从而得到了光滑的等值线.

| Abstract: | The contour lines generating algorithm for quadrilateral meshes which is based on each quadrilateral mesh be divided into four triangles and the contour lines be generated in the four triangles avoids the complex algorithm of contour-point tracking,but the generated contour lines are not smooth.In this paper,the Beaier curves are used to smooth the contour segments in a quadrilateral mesh,which make the all contour lines sommthed. |
