| This system does research on represent, control and management of battlefield three-dimension information. It is used for studying the database structure of storing data model and simplifying and optimizing the 3D model data. It uses object-oriented thinking, database technology and three-dimension technology. The question is how to use the two- dimension attribute of relational database for representing three- dimension data structure. The purpose is to store three dimension model data into relational database. It need define a proper structure in favor of the transmission and security of data. It need simplify and optimize original data according to represent effect of battlefield.In this paper, we define the data structure and perform the mesh simplification method of triangulation in three dimension, 4-8 meshes and edge-collapse algorithm. We also improve on the triangulation in three-dimension and edge-collapse algorithm to represent data faster and reduce the storage of database. |
