Aim To study particle system approaches and propose a falling snow algorithmic structure for particle system application, incorporating the object-oriented computer program language. Present a simulation algorithm structure of particle system for snowing image simulating based on the study of particle system approaches and the object-oriented computer program language, then get a realistic visual effect. Methods By choosing properly particle models and particle quantities and cobine with the OpenGL, the specific structure of falling snow was analyzed to obtain the dynamic falling snow simulating. Results The results of experimentation have proved that this method is more effective in the representation of snows in virtual scene. Conclusion A novel algorithm is proposed, thus effectively solved the problem of weak real-time performance in generally particle system for snow dynamic simulating.
