摘要
根据重磁位场正演模拟的要求,提出了一种基于截面的三维地质体可视化建模方法。该方法利用改进的最短对角线法构建截面间的地质体表面,改进的最短对角线法弥补了最短对角线法不能有效寻找起始点的缺陷,并能够处理任意角点数的截面之间的地质体表面构建。将其应用于重磁位场正演模拟可以使可视化数据结构和计算数据结构一致,简化了算法并提高了计算精度,因而提出的方法是一种有效实用的方法。
According to the potential forwarding of gravity and magnetic,a modeling method to build 3D geological body,which is based on sections of geological body,is proposed.The method constructs the surface of geological body using an improved shortest diagonal algorithm,which can find initial point correctly and overcome the shortage Of classic short diagonal algorithm,simultaneity,can build geological body surface using sections having different quantity of points.Composing mentioned method with potential field simulation can make the data structure of visualization accordant with that of computation and improve the precision of computation,so the proposed method is effective and validate.
