虚拟战场建模技术的研究

首先给出了虚拟战场环境的基本组成,然后就战场中动态实体和特殊效果的建模技术进行了重点论述.考虑到兵力实体的运动规律和运动特征,对兵力实体结构进行了精确分析,并采用放样造型方法和组合建模方法对其几何建模过程进行了论述;针对战火、硝烟等战场场景建模要求,对火焰、烟雾等特殊效果的不规则运动进行了深入的了解和分析,实现了基于粒子系统原理的战场特效动态建模.给出的部分兵力几何建模结果和战场特殊效果仿真结果进一步验证了所提建模方法的可行性和有效性,也为虚拟战场的深入研究奠定了基础.

The research on modeling techniques of virtual battle-field

This paper firstly gave the basic composition of virtual battle-field,and then mainly discussed the modeling techniques of dynamic objects and special effect in battle-field.Considering the kinetic laws and characteristics of military strength,the paper analyzed its structure accurately,and then used loft method and combined method to discuss its geometry modeling process.In allusion to the modeling requirement about flames of war and smoke of gunpowder,this paper analyzed the non-regular behavior of flame and smoke,and realized the battle-field special effect dynamic modeling based on particle system theory.The experiment results of military strength geometry model and battle-field special effect further testified the feasibility and validity of the proposed modeling methods.
