【摘要】 虚拟现实技术具有超越现实的虚拟性。虚拟现实系统的核心设备仍然是计算机。它的一个主要功能是生成虚拟境界的图形,故此又称为图形工作站。海洋场景的建模与研究融合多种现代高级仿真技术,如OpenGL仿真机制的实现等多种技术来处理海洋场景模型,从而组织和封装海底场景的数据。进一步使用纹理映射优化设计及场景动画设计技术,实现三维海景的真实再现。在海底数据信息中加以OpenGL库和VC库,对海洋海底场景的虚拟再现进行研究,这对于海洋战场环境的研究有着开—定的参考的意义。本文综合运用虚拟现实制作技术中三维建模技术方法,通过三维建模流程方式对实体模型库的海底场景进行初步建模,在确定了工程框架程序后用OpenGL在VC++中进行建模变换,从而初步地的实现对海洋系统场景的虚拟建模搭建及转换工作。在建模过程中使用虚拟现实技术、三维数据可视化技术、面向对象的编程。采用了一定的算法和编程模式,针对于初步建模后的图形进行深入的纹理优化,使得场景能够更加真实的再现。运用LOD算法技术简化地形、实现一个大规模的地形渲染系统,抛弃不必要的渲染动作来加快渲染速度,实现三维海洋海底系统场景的建模。更多还原

【Abstract】 Virtual reality technology has virtuality beyond reality and its core equipment is computer. The key feature of the equipment is generating graphs of virtual world, as it is called graphics workstation. The seabed of modeling and research contains many sorts of modern high virtual technology, such as using technology of the realization of OpenGL simulation to deal with the seabed, and it could further optimize the use of the texture map design and animation technology design to realize a truth three-dimensional seabed. Add OpenGL base and VC base to the seabed data and then research on the virtual of the seabed, this situation has the pioneering meaning on the research of the seabed.This article comprehensively with virtual reality production technology of 3D modeling technology and methods, through 3D modeling process on the entity model of the way the library scene for preliminary modeling,determine the engineering framework in after the procedure using OpenGL shipped in VC++ modeling and the realization of the transformation, and the preliminary on ocean system of virtual scene modeling building and the transformation. In the course of modeling using virtual reality technology,3D visualization technology, object-oriented programming. Using fixed algorithm, fixed programming model, make use of various programming model. Based on preliminary modeling of further after the graphic texture optimization, make scene can be more true representations. LOD algorithm using technology to achieve a large-scale terrain rendering system is the key to how to simplify the terrain, abandon unnecessary rendering action to speed up the rendering speed.
