虚拟现实报告

1、虚拟现实技术大作业设计说明书设计题目：放映室姓名：学号：单位：计算机科学与技术030911班一：设计目标说明（描述目标）放映室内有电视可以看视频，听歌，有座位可以聊天休息。风扇可以转动，可移动的玻璃 门。二：设计环境说明（描述本设计所使用的软硬环境）vrmlPad三：设计过程说明（较详细描述自己的设计思路，设计过程，能够体现出本设计是自己做的。， 源代码详细注释.原本想在一个封闭的空间建立自己的作品，真正做的时候发现封闭空间内坐标不容易找 到，于是自己做了一个封闭的空间。由于时间仓促，有些东西做得并不精细。有些贴图网上 找不到，就自己用photoshop做。其中有一部分借鉴了老师和网上提供的例

2、子。首先建立了背景。背景上建立两个立方体，木板状的，作为房顶和地板。然后建立四根柱 子，再将除正面外其余三面墙围起来。正面的墙留着后面做玻璃门。然后在背面的墙建立一个立方体，作为电视机的底座，仿照老师给的例子建立电视机。桌子是由5个圆柱构成的，一个大的作为桌子面，剩下的作为四个腿。然后将房间在另一边复制一张桌子。凳子是有一个圆柱和一个圆构成的，在房间内复制了十 个。然后制璃门，运用时间传感器和位置传感器建立一个可推拉的门，然后在门两边建立玻璃墙。最后建立风扇，风扇需要点一下才能转动。风扇也借鉴了老师的例子。最后给放映厅加了音乐，使其功能更齐全。放映厅有四个视点，分别是左面，右面，正面，和外观。

3、通过这次上机是我了解了 vrml的功能，经历了两天时间，仔细计算各个物体的空间坐标， 学习各个函数功能，终于完成了虚拟现实的大作业。这将对我以后的学习工作上有一定的帮 助的。代码如下：#VRML V2.0 utf8Background (groundColor 0.7 0.6 0.8groundAngle 1.57skyColor 0.2 0.5 0.6DEFveiw1 Viewpoint ( position -20,10,12 description view1DEFview2 Viewpoint ( position 0,6,0 description veiw2 DEFview3 Vi
