Abstract: On the basis of analyzing the present virtual reality technology and the ship engine
control room, the paper implements the establishment of the three-dimension model by using
3D-MAX and the roam and interaction in virtual scene by using XNA, compiles the
two-dimension simulation software by adopting C#, implements the communication between
three-dimension virtual scene and two-dimension based on UDP protocol. According to the
mathematical model of lighting effect, the paper implements one kind of shader based on GPU by
using High level Shader Language (HLSL) which lowers the transmission burden between GPU
and CPU and enhances the sense of reality of virtual scene.

Key words: virtual reality, virtual engine control room, XNA, high level shader language
