摘要
本文给出了一种用于实验数据处理的高精度计算机自动绘等值线算法。该算法能自动生成并细分最优三角形网络,绘出使用户满意的高精度等值线,与同类算法相比有明显特点。
This paper presents a new method which is different from the conventional methods ispresented.The algorithm constructs a locally equiangular triangulation of the data points andcan furthcr fine it,find an interpdating surface using estimated partical detivatives at the points,and evaluates the surface only when drawing the contour lines.The algorithm is modular-thetriangulation and slope cstimation steps and fining procedure is indipendent of the contourdrawing mechanism,the root-finding procedure is indipendent of which the interpolating sur-face function of spaced points or an alalystic function.
