基于OGRE渲染引擎的虚拟现实研究 【摘 要】 虚拟现实(VR)是近年来出现的高新技术。虚拟现实是一项综合集成技术，涉及计算机图形学、人机交互技术、传感技术、人工智能等领域，它用计算机生成逼真的三维视、听、嗅觉等感觉，使人作为参与者通过适当装置，自然地对虚拟世 界进行体验和交互作用，近年来，虚拟现实已逐渐从实验 室的研究项目走向实际应用。目前在军事、航天、建筑设计、旅游、医疗和文化娱乐及教育方面得到不少应用。 但是虚拟现实就目前而言，还有许多值得改进的地方，如何让虚拟现实进入我们生活之中，点击鼠标就可以进行3D漫游，并且开发费用不能太高，而基于OpenGL和Direct3D等SDK的开发效率却比较低下，常常耗费大量的人力物力。 OGRE是一套国外的开源渲染引擎，免费通用可移植性强，非常适合用于进行虚拟现实开发，快速开发+低成本，对虚拟现实的推广普及有极大的促进做了个用。 首先，本文针对OGRE 3D引擎框架进行描述，分别阐述OGRE的几个核心对象，以及他们如何在引擎中组织场景，再从OGRE引擎的脚步入手，分析如何编写材质脚本达到自己需要的效果。 最后本文针对OGRE在虚拟中的优势，制作了一个氢原子演示动画系统，并对其具体实现进行了阐述。 【关键词】OGRE 虚拟现实 演示动画 核心对线 Based on the OGRE rendering engine of virtual reality 【Abstract】Virtual Reality (VR) is a high-tech in recent years. Virtual reality is a comprehensive integrated technology involving computer graphics, human-computer interaction technology, sensor technology, artificial intelligence, it is realistic to use computer-generated three-dimensional vision, hearing, smell and other sense of people as participants, through appropriate device, naturally carried out on the virtual world experience and interaction, in recent years, virtual reality has been a gradual shift from laboratory research to practical application. Currently in the military, aerospace, architecture, tourism, medical and cultural entertainment and education, get a lot of applications. But virtual reality for now, there are many worthy of improvement, how to make virtual reality into our lives, click on the mouse can be carried out 3D roaming, and development costs can not be too high, while the other based on OpenGL and Direct3D SDK Development efficiency is relatively low, often spend a lot of manpower and resources. OGRE is an open source rendering engine abroad, free universal portability strong, well suited for virtual reality development, rapid development + cost of virtual reality promote the spread has made a great use for. First, this paper described the framework of OGRE 3D engine, a few were described OGRE core objects, and how they org
