在列车视景仿真中,加入自然环境的模拟,可以增强视觉效果。在下雨环境下,列车运行时的车窗效果的模拟,可以增加环境对驾驶人员视觉的影响,进而增强模拟器的仿真效果。通过粒子系统和OpenGL贴纹理的方法,模拟雨天列车车窗雨滴效果。将刮雨器模型加入到场景中,通过刮雨器与雨滴粒子的配合,模拟出雨天环境下车窗效果。该方法在满足实时性的前提下,增强了雨天环境下列车驾驶的真实感,满足列车仿真器视景仿真的需求。
In train visual simulation, adding the simulation of the natural environment, can enhance the visual effects. In a raining environment, the simulation of the window effect of the train running can increase the visual impact of the environment on the driver and further enhance the simulation effect of the simulator. Through the particle system and OpenGL stickers texture method, simulated rainy day train window raindrop effect. The wiper model is added to the scene, through the cooperation of the wiper and the raindrops, the simulation of the window effect under the rainy day environment. Under the premise of meeting the real-time performance, the method enhances the realism of train driving in rainy days and meets the demand of train simulator visual simulation.
