摘要: 地质断层数据包括等高线、断层线、断层截面等数据,其中等高线数据是最为主要的部分,然而由于断层线和断层截面的影响,增加了地质断层数据网格化的难度和复杂度,所以如何有效、合理的对它进行网格化也是一个难点问题。本文利用共轭梯度法来求解高度场的泊松方程,给出地质断层数据高度场的生成算法。

Abstract: Faultage datas include contour line, fault line and fault section. And contour line is most important of all. But the faultage data gridding is complicated by the effect of fault line and fault section. To solve this problem efficiently, conjugate gradient method is introduced to evaluate the posson equation of terrain in this paper. And the construction algorithm of the faultage datas is given.

Key words: posson equation, conjugate gradient method, triangulation, rendering
