摘　　要：使用PC机群实现多通道视景仿真,可以在给用户带来强烈的沉浸感和较大的视野的同时得到很高的性能价格比。讨论了包含用户交互控制下的静态场景和独立数据驱动下的动态实体的的多通道视景仿真系统的体系结构,提出了在该结构下的视景同步方法和动态实体的运动平滑算法。实验结果表明两种技术实现了基于PC机群的大规模场景、多运动实体的视景仿真中多通道视景的同步和运动实体的平滑,在保持画面流畅的同时满足了用户的交互要求。The multi-channel visual simulation based on PC cluster can give user strongly immersive feeling and a bigger view,and acquire high performance and low cost meanwhile.Discuss the architecture of multi-channel visual simulation system which includes the static view controlled by the user and the dynamic object driven by separate data.Provide the multi-screen rendering synchronization method and the motion smoothing algorithm for dynamic object under this architecture.The experiments show that the two techniques realize the synchronization of multi-screen and the smooth motion of dynamic object in the multi-channel visual simulation based on PC cluster,keep the view fluent and satisfy the user＇s interaction requirement.
