Abstract:The automatic generation of Particle Effects is an important part of the automatic generation system of mobile phones 3D animation. However, the system lacks of the function of particle effects automatic generation, this paper designs and realizes the automatic generating function of the particle effects. The paper introduces the present situation of ontology library of the phone animation system, studies the qualitative programming of particle effects, and designs a rule reasoning scheme of particle effects. And noted that the difficulties of quantitative realization. Finally, the automatic generation of particle effects is verified by experiments.
