基于GPU，使用CUDA语言，实时模拟上千个粒子的碰撞。在模拟过程中，可通过鼠标和键盘进行交互式操作，方便观测。-Based on GPU,use the CUDA language to realize the simulation of thousands of particles collision

cuda的粒子模拟，非常的逼真,可以控制粒子箱旋转，来观察粒子的运动效果。-cuda based partical simulation, very realistic，you can contral the box which include the particals and watch the motion of the particals.
