OpenGL为API的质点系统，有模拟的重力场、向心力场还有个火焰模型。并且又风力场的接口，希望有人可以完善(OpenGL is a particle system of API, with simulated gravity field, centripetal force field, and a flame model. And the wind field interface, I hope someone can improve)

实现了水流，火焰，风，龙格库塔等物理仿真，效果还可以。(The water flow, flame, wind, Runge Kutta and other physical simulation are realized, and the effect is also acceptable.)
