Preliminary study on geometric modeling of geologic body

摘要

At the first time, the concept and the techniques of geometric modeling of geologic body were proposed. The three-dimensional geologic bodies can be classified into three types: point-like, line-like and plane-like geologic bodies. With geometric modeling techniques and methods, the models for geometric model- ing of various geologic bodies have been derived and their attribute extensions were also dealt with, which pro- vide a new way for describing complex geologic bodies with computer language.
