虚拟环境中实体的获取算法研究

A Research on Entity Capture Algorithm in Virtual Environment

针对舰船损害管制虚拟训练系统中虚拟实体的获取问题,基于武器系统射击效率定义了获取效率这一概念,给出了虚拟场景中线目标和矩型目标的获取效率求解方法。考虑场景中存在多实体获取判定问题,提出了距离补偿判据和视角补偿判据,用于解决目标实体的筛选问题。该算法应用于舰船损害管制虚拟训练系统中,为虚拟场景中目标实体的操作提供了途径。

According to the problem of virtual entity capture in virtual warship damage control training system, a concept of capture efficiency was defined based on the weapon system shooting efficiency. The calculating methods of linear and rectangular target capture efficiency were presented. In consideration of the multi-entity capture determination in virtual environment, distance compensative criterion and visual angle compensative criterion were brought out to solve the target entity filter problem. The algorithm is used in the virtual warship damage control training system to provide an approach for target entity operating in virtual scene.
