航海视景中特效的实时模拟

Real-Time Simulation of Special Effects in Navigation Scene

航海视景仿真中,对特效的模拟非常重要,成功的特效模拟可提高仿真的效果,增加视景的真实感。在分析粒子系统和Billboard两种特效仿真方法的基础上,为了减少模拟所需的粒子数,减小系统开销,利用一种粒子系统和Billboard相结合的方法,同时结合灰级纹理贴图等处理技术,实现了烟、航迹、烟花特效的实时仿真,在基于AndShow_VRToolKit的视景驱动下,取得了令人满意的仿真效果。

In the simulation of navigation scene, the special effects are very important. Successful simulation of special effects can improve the reality of the virtual scene. There are two main methods of particle system and Billboard to do this. In order to reduce the particle number and decrease the system cost, a method which combines particle system with Billboard is used, together with gray level texture and so on. The real-time simulations of smoke, track and fireworks are realized by using this method. Driven by the AndShow_VRToolKit, the simulation effects are very satisfactory.
