基于Vega Prime的航天发射训练仿真视景控制方法

Visual Control Methods for Space Launching Training Simulation based on Vega Prime

仿真技术是解决院校在航天发射训练的教学、科研中,学员难以进行"真枪实弹"的操作与培训等问题的有效途径。由于航天发射任务的多样性和复杂性,在仿真过程中不可避免地要与三维场景交互,因此视景控制是航天发射训练仿真系统的重要环节。Vega Prime是一款支持面向对象技术的实时视景驱动软件,本文针对航天发射训练任务的视景仿真和人机交互要求,分析了基于Vega Prime的场景和对象控制技术,给出联合MFC和Vega Prime实现视景控制的流程,并讨论了实现中的一些主要问题,最后给出演示实例。

Simulation technology has provided an effective way of teaching and research for space launching tasks in uni- versities. It＇s impractical for students to have genuine operations or tutorial in real scenarios. Due to the diversity and com- plexity of space launching tasks, it＇s inevitable to interact with 3D scenarios in the process of simulation. Visual control module is of great importance in space launching simulation. Vega Prime is real time scenario driven software which sup- ports object-oriented development. Taking the requirements of space launching tasks into account, firstly analyzed the sce- nario and object control techniques based on Vega Prime and proposed the visual control workflow combining MFC and Vega Prime. Then the major problems in implementation were discussed. Finally a demonstration was given.
