Simulation of smoke based on number of particle created function
基于粒子数生成函数的烟雾模拟*

In simulation of large-scale virtual battlefield, smoke as an important part, its simulation is of great significance.It was difficult to balance the reality and the real-time in smoke simulation,proposed the level of detail, reducing the numbers of particle in simulation and improving the real-time. At the same time satisfied visual effect.Introduced combining physical model with particle system, added more detail of smoke and generated realistic smoke. Furthermore, imposed the method of threshold controll to judge if the particle should die, which made the simulation more realistic. Experiment testify that the system uses limited numbers of particle producing realistic and real-time smoke scene.
