摘　　要：在视景仿真系统中,三维实体模型的建立对整个系统的开发至关重要。为了有效地利用和管理三维实体模型、组成模型的元件及其纹理,需要有一个数据库管理系统来管理这些模型或者元件。该文提出了在MultiGenCreator下开发开放式的三维模型(元件)库管理软件系统的方法,给出了数据库的组织结构和标准化原则。以MicrosoftSQLServer2000为数据库支撑系统,采用OpenFlightAPI结合ODBCAPI在VisualC++6.0下进行开发,该系统作为MultiGenCreator2.5.1一个插件,可以在三维实体建模的同时对模型(元件)进行入库、查询、删除等管理操作。应用表明利用该系统能够加快三维实体建模速度,有助于视景仿真系统的开发。In visual display system, especially those based on Vega, the creation of three-dimension model is very important. In order to create, use and reuse these models effectively, there should be a model data base management system (MDBMS) to manage these models and components. In this paper the method of developing such an open MDBMS was proposed. The structure of database and the rules of standardization were put forward. Microsoft SQL Server 2000 was used as the database supporting system in this MDBMS. Developed under Visual C++6.0 and using Open-Flight API and OBBC API as the programming interface, this open MDBMS is a plug-in of MultiGen Creator 2.5.1 and can do such operations on the models (components) as saving, querying, deleting, appending and so on when user is creating models. This open MDBMS can help user to save time in modeling as well as developing of visual simulation system.
