| Abstract: | The virtual scene of Vehicle Simulator in the view of real-time precipitation is simulated.By optimizing the particle system and adding to the sprite and shader,a parameterized and adjustable special effect of real-time raindrop and real-time snow is made.With the acceleration of GPU hardware,this method is successfully applied to the Vehicle Simulator System based on OSG graphic toolkit.The results show that the system shows better real-time performance and immersion. |
