虚拟现实技术期末作业

虚拟现实技术期末考评汇报院系：计算机科学与技术班级：10班学号：53141007姓名：袁雪峰

试验目标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，构建逼真三维场景。试验要求此次试验为综合性质试验，要求自行设计一个较为复杂场景或者单体模型，其中包含各种造型与渲染技术，比如纹理材质、光照、环境背景、声音视频、动画与交互等。场景内容不限。试验内容利用vrml语言结构了一个虚拟现实世界。运动物体包含气球，火车，汽车，交通灯等，静止物体包含山脉，树林，房屋，人物，花草，电话亭，国旗，座椅，广告牌，雨伞等，另外还包含背景和声音。结构一个背景：天空，草地。将山脉和树林放置于草地上，铺设铁轨和公路，设置火车和各种汽车运行轨迹，放置气球并使其做圆周运动。将电话亭等各部件按照百分比和位置放置，加入背景声音，虚拟世界基本结构完成。试验软硬件环境win10系统，VrmlPad，Cortona3Dviewers（64-bit）,IE浏览器.试验步骤，截图以及代码VRML语言介绍：VRML（Virtual

Reality

Modeling

Language）即虚拟现实建模语言。是一个用于建立真实世界场景模型或人们虚构三维世界场景建模语言，也具备平台无关性。试验步骤以下：首先分别制作分场景（使用图片和VRML语言）使用VRML语言进行场景合并，并调试其中场景坐标。注：对以上工作惯用节点函数进行描述：Transform节点语法Transform{

children[]#所包含子节点列表

translation0.00.00.0#x,y,z方向上平移值

rotation0.00.01.00.0#x,y,z方向旋转轴标识，旋转角度（用弧度表示）

scale1.01.01.0#x,y,z方向缩放因子

scaleOrientation0.00.01.00.0#在x,y,z方向轴上旋转一定弧度后，在按scale因子缩放

Center0.00.00.0#新旋转或缩放中心点x,y,z坐标

}children域中值能够是Shape节点，Group节点或另一个Transform节点。VRML中节点有以下几个类型:
