摘要
对分布式动漫渲染系统的建模技术进行了研究,首先,分析了分布式动漫渲染系统中的两种典型架构--集中式架构和分布式架构的渲染过程,并在此基础上分别建立了集中式架构和分布式架构的SPN(Stochastic Petri Nets,随机Petri网)模型,然后进一步采用SPNP(Stochastic Petri Nets Package)6.0软件对两种架构的平均时延进行了模型仿真分析,最后,得出了2种架构的性能优劣比较结论,为渲染系统在构建和设计阶段提供重要的理论依据。
The modeling for distributed rendering system was studied. Firstly, rendering processes of two typical infrastructures for distributed rendering system, i.e. ＂Centralized＂ infrastructure and ＂Distributed＂ one, was analyzed. Then, two SPN models were constructed for the infrastructures respectively. Furthermore, average time delay was chosen as a key performance index to evaluate the performance of two proposed models with SPNP （Stochastic Petri Nets Package） 6.0 software. Finally, some conclusions about two infrastructures＇superior and inferior were derived thereby, which provides some important theoretical bases for constructing and designing distributed rendering system.
