船舶集控室虚拟仿真系统的设计与实现

摘要

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.%在分析现有虚拟现实技术与船舶集控室的基础上,采用3D-MAX与XNA分别实现了三维模型的建立与虚拟场景的漫游和交互,应用C#语言编写了集控室的二维模拟软件,通过UDP协议实现了三维虚拟场景与二维模拟软件之间的通讯.根据光照效果的数学模型,采用高级着色语言(HLSL)开发了一种基于GPU的着色器,降低了GPU与CPU之间的传输负荷,增强了虚拟场景真实感.
