应用粒子系统模拟模糊不规则物体的关键问题是真实感和实时性,在剖析影响真实感和实时性的因素基础上,提出了提高粒子系统真实感和实时性的有效方法。为提高真实感而将粒子、粒子源、力产生器统一在一起,即将粒子源、力产生器和可视化粒子看作都由力驱动。用合适的力类产生较好的火、烟、云及爆炸的实时模拟,用OpenGL显示列表技术提高绘制效率,简化粒子的碰撞处理来减少计算复杂性,利用层次空间减少计算工作量。实验结果表明,该方法满足实时性和真实感的要求。

The primary problem to apply particle system for modeling irregular objects is its reality and real time. Presents several methods to solve it based on analyzing affect of reality and real time. Unifys particles particle sources and force generators. In the particle system the particle sources and force generators are subject to the forces as well as visual particles. This fundamental change, along with suitable set of force classes, enables us to create better real - time simulations of fire, smoke, clouds, and explosions. Use OpenGL display list to optimizing rendering, simplifying collision detection to decrease computing time, hierarchical spatial subdivision to reduce the computational workload, Examples illustrate that the method can meet the requirements of real time and reality.
