| 摘 要： | 提出一种绘制规则离散点的等值线的算法，在以搜索到的测点为中心的一个矩形区域内搜索下一点，与过去已搜索到的测点所确定的2次B样条曲线的切线距离最小的点为等值线的下一点，把所有搜索到的点拟合成3次B样条曲线则得等值线。

| Abstract: | A new algorithm for drawing isoline of regular dispersed points is presented. Searches next point of the isoline in a rectangle which center is the searched point. Next point of the isoline is the point whose distance from the tangent line of a quadratic B-spline which is determined by the searched points is the shortest. The isoline is a cubic B-spline which is determined by all searched points. |

| Keywords: | algorithm isoline B-spline |
