摘要
使用粒子系统实现的喷泉效果能够有效的增强三维场景的真实感,但传统的粒子系统在实时仿真中,粒子总数最多只能达到一万个左右,限制了喷泉规模和模拟效果。针对上述问题,提出了基于GPU加速的粒子系统喷泉模型,该方法将所有计算全部放在GPU中进行并行加速处理,提高了算法的运算速度,能够对100万数量级的喷泉粒子进行实时绘制,同时还模拟了水滴运动的视觉图像残留效应,有效地提高了喷泉的真实感。
The fountain effect realized by particle system can consumedly enhance the reality in three-dimensional scenes. However, traditional particle system can only handle about 10000 particles and therefore has a great limit on the fountain scale and simulation effect. Due to the problems mentioned above, a new fountain model raised based on GPU acceleration, which could render up to 1 million particles in real-time simulation. In addition, this model also achieves persistence of vision effect in water droplets' movement, and effectively enhances the fountain's reality.
