摘　　要：针对海上消防实训困难,费用昂贵的问题,基于开源场景图形(OpenSceneGraph,OSG)渲染引擎和Bullet物理引擎开发了海上消防三维仿真系统。设计中使用事故船舶视口和消防船舶视口双视口的观察形式来增强仿真效果;运用OSG粒子系统模拟实现爆炸失火和消防水柱的粒子效果;通过实时计算火焰和水的粒子参数并根据碰撞力学运用Bullet检测水粒子和火源的碰撞,从而来实现对火势的控制。实验结果表明,OSG和Bullet的结合实现了实时控制粒子系统来模拟消防场景,并具有逼真的仿真效果。上述仿真系统使受训人员在近似实战的环境中训练,提高训练效率,实现训练数字化,降低训练成本,同时提升受训人员的灭火救援和指挥决策能力。In view of the difficulty and high cost of the marine fire training,the three-dimensional simulation system of the marine fire protection based on OpenSceneGraph（OSG） rendering engine and Bullet physics engine is developed.During the design,the form of double viewport observation including accident ship viewport and fire ship viewport is used to promote the simulation effect;OSG particle system is applied to achieve the explosion of fire and fire-fighting water column particle effects;the particles parameters of flame and water are calculated in real time,and the Bullet is used to detect the collision between water particles and fire source according to the collision mechanics,thus the fire control is achieved.The experimental results show that the combination of OSG and Bullet can realize real-time control of particle system to simulate the fire scene,and has the realistic simulation results.The simulation system allows trainees＇ training in an environment which is similar to actual,which can improve training efficiency,realize the training of digital and reduce training cost,while enhance the trainees＇ abilities of fire rescue and command.
