STK中可视化实体模型的设计与运动控制

Design and Movement Control of Visual Entity Models in STK

卫星工具包(SatelliteToolKit,STK)被广泛应用于针对航天任务的可视化仿真系统中。为了满足具体的仿真任务对于可视化场景的要求,需要建立基于特定的用户需求的模型。STK软件中包含了大量具有复杂几何外观的实体,这些实体除造型之外,还具有许多与仿真过程密切联系的属性。在介绍STK中模型文件组成内容的基础上,讨论了STK中实体模型设计、构造的一般方法、模型运动控制的有关问题,并简要说明了模型转换软件LwConvert的使用。

Satellite Tool Kit（STK） is widely used in the visualization simulation system for space mission. For some idiographic missions,it is necessary to build models based on the unique requirements of users. Usually, various entities with sophisticated surfaces are used in the software. Besides their exteriors, these entities are tied up with the simulation process in some other aspects. Based on the introduction of the model file in STK ,this paper discusses the general methods used to design and build entity models as well as the problems about model movement control. The usage of the conversion software LwConvert is also mentioned.
