Abstract: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 modeling of various geologic bodies have been derived and their attribute extensions were also dealt with, which provide a new way for describing complex geologic bodies with computer language.

 

Key words: geologic body geometeric modeling computer-aided design
