摘要
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.
