Abstract
An attempt to make a computerized solid model of geologic system is introduced. This paper describes that computer graphics of solid models is a great help to understand complex geologic structures correctly.
An actual geologic structure studied by geologists is used as an example model. The model covers 18km×25km area and 5km in depth. More than ten complex faults and eleven types of rock are included in the model.
This paper also describes, necessary input data for the modeling, which are topographical data of ground surface, geologic maps at several sections, and attribute relation data which provides mutual relations of the sections. The kriging algorithm is used for modeling surface boundaries of subterranean layers. A solid modeling software in market was used in this study and the process of creating the geological solid model with the software is also presented.
