摘　　要：基于SPN(Stochastic Petri Nets,随机Petri网)模型方法,分别对典型的非对称动漫渲染系统结构下的3种渲染模式下的渲染服务进行了性能分析。首先,分析了渲染系统的渲染过程,并在此基础上分别构建了不同渲染模式下的SPN模型,然后选取平均时延作为渲染系统的性能评价指标,采用SPNP6.0软件对上述3个SPN模型进行了示例分析,最后,通过3个SPN模型的性能评价结果,得出了3种渲染模式的性能优劣比较结论,为非对称动漫渲染系统的构建提供了重要的理论依据和设计思路。In this paper,performance analysis of three rendering modes for rendering services under a typical asymmetric animation rendering system framework is carried out by Stochastic Petri Net model-based analysis.Firstly,the rendering process of rendering system is analyzed and on the basis of analysis,three SPN models for one pc node(1 PC) rendering mode,one pc node and another cluster node(2 PCs) rendering mode,one pc node and one cluster node together with another average pc node(3 PCs) rendering mode are constructed respectively.Then average time delay is chosen as a key performance index to evaluate the performance of three constructed models with SPNP(Stochastic Petri Nets Package) 6.0 software.Finally,through comparison analysis of performance evaluation,some conclusions about three modes' superiority and inferiority are derived as well,which offers some theoretical foundations and designing ideas for constructing asymmetric animation rendering system.
