基于基础特效库的战场特效模型及其实现

A Model of Special Effects in Battlefield and Its Realization Based on General Special Effects Libraries

战场特效是虚拟战场自然环境建立的重要组成部分,其极大地影响虚拟战场视景仿真效果的真实感和用户的沉浸感。为了实现对多种战场特效的快速绘制,基于粒子系统的原理,文中建立了包含火焰、烟雾等多种效果的基础特效库,根据战场特效实时性、随机性、复合性的特点,建立统一的模型和算法。通过对基础特效进行有序的约束和配置,可以快速实现对多种复杂特效的模拟,仿真效果逼真且满足实时性的要求,可以有效提高虚拟战场的沉浸感。

Special effects are an important part in establishing virtual battlefield environment. The simulation of special effects makes enormous influence on the realism of simulation system and user＇ s immersion feeling. In order to achieve the fast rendering of a variety of special effects in battlefield, based on the principle of the particle system, established the effects library foundation including fire, smoke and so on. According to the battlefield effects characteristics of the real-time, randomness and compound, established the unified model and algorithm. By means of orderly constraints and configuration for base effects, can quickly achieve the simulation for a variety of com- plex effects,the simulation results are vivid and meet the requirement of real-time,can effectively improve the virtual battlefield immer- sion.
