Design of 3D Visual Digital Basin Model System

This paper describes basic design object,main data and basic functions of 3D digital basin model system,which are designed under GIS and OpenGL environment,and presents some 3D structural result pictures obtained through the system.The system provides a direct analyzing and distinguishing measure to research the basin structure and oil gas.Analysts can excavate the hidden information of the structure and oil,and estimate the consistency and rationality of the known model data according to the data superposition from the different origin in 3D space.
