Simulation of Rain and Snow in Visual Simulation of Train Operation

  • A simulation method for rain and snow in visual simulation of train operation was proposed.A real-time rain and snow particle system was designed based on the physical model of raining and snowing.The implement of the particle system was discussed,including the definition of particles,control of particle lifecycles,and so on.In the system,a visual area is defined to simulate the obstructing effect on the rain and snow particles by a tunnel or a railway station.Particle positions are calculated by a simplified dynamic model,and the billboard technique is employed to render particles.Application of the proposed method shows that the rain and snow particle system performs well for real-time rendering of complicated raining and snowing in visual simulation of train operation.
