1、虛擬校園論文：基于VRML校園漫游系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)【中文摘要】近幾年來,隨著虛擬現(xiàn)實(shí)技術(shù)(VR)的快速發(fā)展,其應(yīng)用領(lǐng)域不斷增加,許多高校也相繼開發(fā)出了基于VR的虛擬校園系統(tǒng)。作為數(shù)字校園的重要組成部分,虛擬校園不但能提供在校園中漫游的功能,而且還能夠?qū)崿F(xiàn)復(fù)雜的交互,甚至可以操縱后臺(tái)數(shù)據(jù)庫,提供數(shù)據(jù)庫檢索等功能,同時(shí)虛擬校園在校園的規(guī)劃建設(shè)和遠(yuǎn)程教育方面也發(fā)揮著重要的作用。本文在研究了虛擬現(xiàn)實(shí)相關(guān)技術(shù)的基礎(chǔ)上,以寧夏理工學(xué)院為模型,開發(fā)出了一套虛擬校園漫游系統(tǒng),實(shí)現(xiàn)了校園場景的實(shí)時(shí)漫游和部分交互功能。通過對虛擬
2、校園漫游系統(tǒng)的需求分析,制定了系統(tǒng)的總體設(shè)計(jì)方案,利用3DMax和VRML對虛擬校園場景中的各類物體進(jìn)行建模;為了解決虛擬場景的畫面質(zhì)量和系統(tǒng)運(yùn)行的實(shí)時(shí)性之間的矛盾,本文從場景優(yōu)化、文件壓縮等方面入手,提出了虛擬現(xiàn)實(shí)漫游系統(tǒng)的改進(jìn)方案;研究了虛擬校園中的交互技術(shù),并利用Java語言與VRML的兩種接口方式實(shí)現(xiàn)了場景中的交互。經(jīng)過對系統(tǒng)的瀏覽效果進(jìn)行測試,結(jié)果表明:本系統(tǒng)具有較好的實(shí)時(shí)性、交互性和良好的視覺效果。用戶不僅可以瀏覽校園,而且可以在瀏覽過程中對場景進(jìn)行一些簡單的交互。【英文摘要】Recentyear
