数据场可视化的可变形表面抽取技术

文章主要描述了一个从标量和矢量场进行表面抽取的通用方法。在体数据场中，先给定一个初始多边形面，面的形状根据移动规则通过表面结点的迭代移动来近似场。为得到一平滑表面的良好近似，多边形网格在迭代中可局部细化。抽取的表面类型由移动规则函数决定，可以是场变量的任意函数。

Deformable Surface Extracting for Visualization

This paper mainly describes a universal method for extracting surface from scalar and vector fields. In data fields,a initial polygon surface is given,the shape of space is adapted to the fields by the surface nodes' interactive displacement,and the polygon grids are refined. The displacement criterion which can be any function of the available field variables determines the type of surface.
