随机过程模型及等值线绘制的游动网格法

STOCHASTIC PROCESS MODEL AND MOVING-GRID CONTOURING ALGORITHM

本文介绍了一种等值线绘制的数学模型——随机过程模型,该模型具有过全部已知数据点及全部偏导数连续等优点。还提出一种新的等值线绘制算法——游动网格法,该算法在保证高精度的基础上加快等值线绘制的速度,并能适用于复杂边界区域的等值线的绘制。在此基础上,编制并实现了一个通用等值线绘制的软件包。

In this paper,a kind of interpolation function which is called stochastic process model is in-troduced,which is continous in all derivatives and passes exactly through the given data points.Also,a new contouring algorithm called moving-grid algorithm is described here which raises thespeed of contouring with high precision and is appliable for contouring in the region with compli-cate boundary.Based on the above,a general contouring software package is implemented.
