虛擬現(xiàn)實(shí)技術(shù)期末作業(yè)

1、虛擬現(xiàn)實(shí)技術(shù)期末考核報(bào)告 院系：計(jì)算機(jī)科學(xué)與技術(shù) 班級(jí)：10班 學(xué)號(hào)：53141007 姓名：袁雪峰1 實(shí)驗(yàn)?zāi)康恼莆仗摂M現(xiàn)實(shí)技術(shù)復(fù)雜三維場(chǎng)景建模技術(shù)。在場(chǎng)景中引入環(huán)境背景、動(dòng)畫(huà)與交互等，構(gòu)建逼真的三維場(chǎng)景。2 實(shí)驗(yàn)要求本次試驗(yàn)為綜合性質(zhì)試驗(yàn)，要求自行設(shè)計(jì)一個(gè)較為復(fù)雜的場(chǎng)景或者單體模型，其中包含各種造型與渲染技術(shù)，比如紋理材質(zhì)、光照、環(huán)境背景、聲音視頻、動(dòng)畫(huà)與交互等。場(chǎng)景內(nèi)容不限。3 實(shí)驗(yàn)內(nèi)容運(yùn)用vrml語(yǔ)言構(gòu)造了一個(gè)虛擬現(xiàn)實(shí)世界。運(yùn)動(dòng)物體包括氣球，火車，汽車，交通燈等，靜止物體包括山脈，樹(shù)林，房屋，人物，花草，電話亭，國(guó)旗，座椅，廣告牌，雨傘等，另外還包含背景和聲音。構(gòu)造一個(gè)背景：天空，草地。

2、將山脈和樹(shù)林放置于草地上，鋪設(shè)鐵軌和公路，設(shè)置火車和各種汽車的運(yùn)行軌跡，放置氣球并使其做圓周運(yùn)動(dòng)。將電話亭等各部件按照比例和位置放置，加入背景聲音，虛擬世界基本構(gòu)造完成。4 實(shí)驗(yàn)軟硬件環(huán)境win10系統(tǒng)，VrmlPad，Cortona3D viewers（64-bit）,IE瀏覽器.5 實(shí)驗(yàn)步驟，截圖以及代碼VRML語(yǔ)言簡(jiǎn)介：VRML（VirtualRealityModelingLanguage）即虛擬現(xiàn)實(shí)建模語(yǔ)言。是一種用于建立真實(shí)世界的場(chǎng)景模型或人們虛構(gòu)的三維世界的場(chǎng)景建模語(yǔ)言，也具有平臺(tái)無(wú)關(guān)性。實(shí)驗(yàn)步驟如下：1. 首先分別制作分場(chǎng)景（使用圖片和VRML語(yǔ)言）2. 使用VRML語(yǔ)言進(jìn)行場(chǎng)景

3、合并，并調(diào)試其中場(chǎng)景的坐標(biāo)。注：對(duì)以上工作常用的節(jié)點(diǎn)的函數(shù)進(jìn)行描述：Transform節(jié)點(diǎn)語(yǔ)法Transform children # 所包含的子節(jié)點(diǎn)列表translation 0.0 0.0 0.0 # x,y,z方向上平移的值ro tation 0.0 0.0 1.0 0.0 # x,y,z方向旋轉(zhuǎn)軸標(biāo)識(shí)，旋轉(zhuǎn)角度（用弧度表示）scale 1.0 1.0 1.0 # x,y,z方向的縮放因子scaleOrientation 0.0 0.0 1.0 0.0 # 在x,y,z方向軸上旋轉(zhuǎn)一定弧度后，在按scale因子縮放Center 0.0 0.0 0.0 # 新的旋轉(zhuǎn)或縮放中心點(diǎn)的x,y,z
