摘　　要：在分析三维地质体建模特点的前提下,利用计算机图形学相关知识,提出了一种利用二维剖面构建三维块状地质模型的方法.该方法以用户编辑的二维地质剖面为输入,寻找地质块体的拓扑关系,自动构建以地质块体为单元的块状三维地质模型,且能够让用户充分利用已有资料进行交互式建模.应用实例表明该方法简单有效,具有较强的实用性.Under the condition of analysis the characteristics of 3-dimensional modeling, using computer graphics related knowledge, this paper proposes an algorithm which uses two-dimensional geological cross section to construct the three dimensional geological model. Based on the firsthand information about 2D geological cross section edited by users, the algorithm searches the topological relations of geological blocks. It can use the geological blocks as the elements to automatically construct the 3D geological models. Moreover, the algorithm can utilize the existing data to interaetively modeling. The experiments demonstrate that the proposed algorithm is simple, efficient and practicable.
