基于粒子系统的战场特效通用模型的设计与实现

Design and implementation of general model about special effects in battlefield based on particle system

按照仿真实现抽取了各种战场特殊效果的共性,采用面向对象技术将特效的物理特性的数学描述和表现特性的可视化描述相分离,同时结合程序式随机过程控制粒子系统的各特性模拟,并对通用模型采用基于视点距离进行了优化,实现了层次组织的类库,较好地满足了大规模虚拟战场环境仿真对特殊效果仿真真实性、实时性和开放性等要求。最后给出了一个基于通用模型扩展的实例。

The common characteristics of various special effects were distilled for simulation of battlefield. The objectoriented technology was adopted to separate the mathematical description of physical properties and the visualized description of representation characteristics special effects. The simulation of various characteristics was controlled by the random process of program schema, and the general model was optimized by adopting viewpoint-based distance, and then the class libraries with the level form was realized. As a result, the requirements of authenticity, real-time and openness were satisfied for the special effects simulation in large-scale virtual battlefield environment. Finally, an example was expounded based on the expansion of the general model.
