Abstract: This paper implements the multi-channel visual simulation which can supply a larger vision and a strong sense of immersion and obtains the high performance/cost ratio for the user by using PC cluster. It studies the system framework of multi-channel visual simulation system based on PC cluster, uses OSG as 3d rendering engine, proposes an easy method which is based on projection transformation to split the screen. The experimental results show that using this method can avoid bending and split screen easily and flexibly, achieving the purpose which expands the field of vision or has a bigger display size conveniently, keeping the visual and interaction in every channel synchronous and the picture fluent.

Key words: Open Scene Graph（OSG）, multi-channel visual simulation, split screen technology, computer cluster
