仿真建模软件Creator的应用技术

Creator是用于创建逼真的三维模型和复杂地形的工具软件，其文件格式．flt在实时三维领域中已成为最流行的图像格式，并成为仿真领域的行业标准。该文介绍了该软件的使用方法和主要功能。文章首先分析了Creator的数据库层级结构和节点类型，对Creator建模工具箱的主要功能进行了总结，对其道路创建工具、地形创建工具等建模工具的特点和功能进行了阐述，之后对模型中的光源与光线渐变、不同细节层次的节点建模、使模型产生运动等方面进行了分析，对软件应用中应当注意的问题进行了讨论，最后展示了一个完成的仿真模型．并对Creator与其它软件结合进行虚拟仿真的方法进行了探讨。

Application of the Simulation Modeling Software Package-Creator

Creator is a software package that produces realistic three-dimensional models and complex terrain for use in realtime applications. Its file format (.flt) has become the most popular one and the industry standard in the simulation-modeling field. This paper introduces the usage and functions of Creator. First of all, the hierarchy of its database and its node types are analyzed. Secondly, the main functions of its toolboxes are summed up. The functions and features of its Road Tool and Terrain Tool are expatiated later. Then the Light Sources and Database Shading, Levels of Details and Make Things Move are analyzed. In the discussion the keys to which attention should be paid during the modeling are mentioned. At last a finished simulation model is given to explain the application of Creator and the virtual simulation method for combining Creator with other software is discussed.
