摘　　要：球幕动画电影后期制作流程复杂,如果使用传统的渲染农场软件完成,执行效率不高。为了解决此问题,文中分析了球幕动画电影的制作工作流程,利用渲染农场技术,基于Win-dows HPC高性能计算包,设计并搭建了利用集群计算机进行分布式计算的渲染管理系统。该系统通过分层作业模板,实现了球幕动画电影工作流程的集成化,用户可以根据需要定制作业,通过并行计算完成所需的制作步骤。通过预渲染机制,合理分配计算资源并有效控制任务粒度大小,获得更高的计算效率。该系统已应用于北京天文馆,参与完成多部动画电影的制作工作,稳定性强,效果良好。该系统的实现,扩展了渲染集群的适用范围,简化了用户的手动操作,提高了球幕动画电影的制作效率,具有理论意义和应用价值。The post⁃production process of animated dome show is complex and inefficient executing in when done using tra⁃ditional renderfarm software.In order to solve this problem,this paper analyses the post⁃production workflow of animated dome show,designs and builds a renderfarm system that uses clustered computers for distributed computing based on the Windows HPC high⁃performance computing package with renderfarm technology.The system achieves an integrated work⁃flow for animated dome show through hierarchical job templates,and users can customise jobs as needed to complete the required post⁃production steps through parallel computing.Through the pre⁃rendering methods,rationally allocate computa⁃tional resources,and effectively control task granularity to obtain higher computational efficiency.The system has been ap⁃plied to Beijing Planetarium and participated in the production of several animated dome shows with high stability and good results.The implementation of this system extends the applicability of rendering clusters,simplifies the manual operation of users,and improves the production efficiency of animated dome shows,which has theoretical significance and application value.
