粒子系统在飞机火灾消防视景仿真中的应用

Application of particle system in visual simulation of fire fighting of airplane

文章针对机场消防车驾驶训练模拟器飞机火灾消防的视景仿真,提出通过对粒子系统的实时控制实现消防情景的模拟。视景基于Vega软件建立了飞机火灾场景,通过Vega特效模块中粒子特效的设置模拟了飞机火灾的火焰烟气以及消防车喷洒的灭火剂;设计了控制算法,根据火灾情景的发展和消防车驾驶员的操纵输入,实时计算火焰烟气和灭火剂喷射的相关参数,实现灭火操作和灭火过程的实时模拟。实验表明,该方法能够满足飞机火灾消防实时模拟的逼真度和实时性要求,提高了机场消防车驾驶训练模拟器训练人员的沉浸感。

In view of the visual simulation of fire fighting of airplane with airport fire engine driving training simulator ,the utilization of real-time control of particle system in the realization of fire fight-ing scene simulation was promoted .Visual scene of fire of airplane was constructed based on Vega software .Through setting special effect of particle system in special module in Vega ,flame and smoke of fire of airplane and fire extinguishing liquid ejected from fire engine were simulated .Control algo-rithm was designed ,which calculated the parameters of flame and smoke and ejection of fire extinguis-hing liquid based on the development of fire scene and the input of control of driver of fire engine .And the real-time simulation of operation and process of fire extinguishing was realized .The experimental results show that this method can satisfy the requirements of fidelity and real-time quality of the real-time simulation of fire fighting of airplane ,w hich promotes the immersion feeling of person in training with airport fire engine driving training simulator .
