Now the advanced visual simulation system is usually equipped with the large-wide projection or multi-projection display system, and several graphic workstations to achieve the real-time rendering task for multiple channels, which can provide the large field of view for user and bring the immersive feeling with the interactive devices' supporting. This paper presented a novel multi-channel visual simulation system with on one single PC, analyzed the system architecture of multi-channel visual simulation and the process of visual generation, studied the technology bottlenecks and the key factors of visual simulation expanding from single to multi-channel, and presented a visual simulation expanding scheme based on graphics card programming. The experimental results verified that this scheme has a more flexible and scalable architecture, a close or even better performance compared to distributed simulation system based on PC cluster, and easier to expand and upgrade, the system cost will be cut down. 1 |
