1、虚拟现实技术期末考核报告 院系：计算机科学与技术 班级：10班 学号：53410 姓名:袁雪峰一 实验目的掌握虚拟现实技术复杂三维场景建模技术。在场景中引入环境背景、动画与交互等,构建逼真的三维场景。二 实验规定本次实验为综合性质实验，规定自行设计一种较为复杂的场景或者单体模型,其中涉及多种造型与渲染技术，例如纹理材质、光照、环境背景、声音视频、动画与交互等。场景内容不限。三 实验内容运用vml语言构造了一种虚拟现实世界。运动物体涉及气球,火车,汽车，交通灯等,静止物体涉及山脉，树林，房屋,人物，花草，电话亭，国旗，座椅,广告牌，雨伞等,此外还涉及背景和声音。构造一种背景：天空，草地。将山脉和

2、树林放置于草地上，铺设铁轨和公路，设立火车和多种汽车的运营轨迹，放置气球并使其做圆周运动。将电话亭等各部件按照比例和位置放置，加入背景声音,虚拟世界基本构造完毕。四 实验软硬件环境wn1系统，rmlPd,Cortna3Dviewers（6-bi），IE浏览器.五 实验环节,截图以及代码RML语言简介：V(VitulRetyMdeiLaguag)即虚拟现实建模语言。是一种用于建立真实世界的场景模型或人们虚构的三维世界的场景建模语言，也具有平台无关性。实验环节如下:1. 一方面分别制作分场景（使用图片和VRML语言)2. 使用VRML语言进行场景合并,并调试其中场景的坐标。注：对以上工作常用的节点
