摘　　要：针对当前弹药爆炸效果研究存在的不足,对虚拟现实场景中弹药爆炸的可视化效果展开研究。阐述粒子系统与弹药爆炸的基本原理,分析粒子系统中火焰粒子与爆炸破片在纹理上变化的不同规律,并给出设计实例;分析推导爆炸破片飞散的衰减模型,对其在虚拟场景中的实际运用进行相应简化,并通过实例进行验证。实验结果表明:该方法相比传统直观模拟的方法有一定的提高,能取得相对较好的可视化效果。Aiming at the shortcomings of the current research on the effect of ammunition explosion, the visual effect ofammunition explosion in virtual reality scene is studied. Expounded the basic principle of particle system and ammunitionexplosion, analyzed of different characteristics of flame particle and explosive particle system changes in texture, and adesign example was given. Analyzed derived and the attenuation model of explosion fragmentation, the actual use of thevirtual scene in the phase should be simplified, and was verified by practical examples. Experimental results show that theproposed method has a certain improvement, compared with the traditional visual simulation method, and can achieve arelatively good visual effect.
