摘　　要：利用截面信息重构三维体是地质三维解释方法的重要发展方向,这里在研究最小表面积和最大体积法的基础上,吸取"最短对角线法"的优点,提出了最优路径(OP)算法,将二维截面的属性块自动连接成三维体,并与计算机图形交互技术结合,形成人机交互建模技术。该方法具有原理简单,易于实现和三角形连接效果较好等特点,对提高地质、物探数据解释工作的效率和准确性有着重要意义。Using cross-sections information to reconstruct 3D model is the important development direction of 3D geological interpretation.In this paper,on the basis of the minimum surface area and the maximum volume method,assimilating the merit of 'the shortest diagonal',the optimal path(OP) algorithm is proposed,and property part of 2D cross-sections are automatically linked into 3D body,and technology of human-computer interaction modeling combining with the technology of computer graphics is formed.This method is simple in principle and easy to implement,also it is better in triangle-connection,which is very meaningful to improve the efficiency and accuracy of the geophysical data interpretation.
