摘　　要：实时仿真中,二维实体表达的效率是影响系统实时性的重要因素,提高二维实体表达效率的关键技术是透明位图显示,通过DirectDraw、GDI+和GDI显示透明位图技术的分析及对比实验,提出了利用GDI光栅操作技术实现二维实体实时表达的优选方案。最后,给出了实时仿真中实体作战威力、毁伤程度、攻击、探测和干扰等行为、状态的动态表达效果。The efficiency of two-dimensional entity expression is the key factor to affect the capability of real-time system in real-time simulation.The key technology to improve the efficiency of two-dimensional entity expression is displaying transparent-bitmap.Through analysis and comparison for the technology of displaying transparent-bitmap among DirectDraw,GDI＋and GDI,an optimum scheme of two-dimensional entity expression using raster operation of GDI was put forward.At last,some dynamic effects of the entity’s behavior and state in real-time simulation,such as fight-power, damage-degree,attaching,detecting and interfering,were given.
