        基于虛擬現(xiàn)實技術(shù)的景物仿真
         
        摘要:虛擬現(xiàn)實(Virtual Reality,簡稱VR),是1種基于可計算信息的沉浸式交互環(huán)境。具體地說,就是采用以計算機(jī)技術(shù)為核心的現(xiàn)代高科技生成逼真的視、聽、觸覺1體化的特定范圍的虛擬環(huán)境,用戶借助必要的設(shè)備以自然的方式與虛擬環(huán)境中的對象進(jìn)行交互作用、相互影響,從而產(chǎn)生親臨等同真實環(huán)境的感受和體驗。
        本設(shè)計是1個基于VRML(虛擬現(xiàn)實建模語言)的虛擬校園系統(tǒng),它要求實現(xiàn)虛擬現(xiàn)實中基本的場景建立和在場景中漫游,本程序建立場景所需的建筑物均在3DS MAX中建立,然后以VRML97的格式導(dǎo)出并保存為.wrl文件,這樣在VrmlPad編輯器中可以打開這些文件了。然后在VRML編輯環(huán)境下,通過添加材質(zhì)、紋理、傳感器、聲音、動畫等來完善該虛擬校園系統(tǒng),并通過內(nèi)聯(lián)(Inline)、錨點(Anchor)造型節(jié)點來實現(xiàn)室外與室內(nèi)的鏈接和切換。最后在VRML瀏覽器中通過鍵盤和鼠標(biāo)的移動來漫游觀看該虛擬系統(tǒng)。為了使場景漫游更真實,還須在場景圖中設(shè)置碰撞節(jié)點,從而防止觀察者從場景中的物體(如教學(xué)樓)中穿過或進(jìn)入不可見的視角觀察。

        Scenery Simulation base on Virtual Reality Technology
         
        Abstract: Virtual Reality(VR), It is a immersing type base on the communication that could be calculate. Concretely to say, adopt taking technology of the computer as the core modern Hi-Tech turn into lifelike look ,listen,sense of touch integrated specific fictitious environment of range, users carry on the reciprocation , influence each other with the target in the fictitious environment by way of nature through the essential equipment, thus produced and came personally the feeling and experience of the true environment equally.
        It is a system of virtual reality school based on VRML technology,and it demands realizing that the basic scene is set up and one can roam in the scene of virtual reality, This procedure sets up buildings of the scene in 3DS MAX then exports and saves them in the format of .wrl files. Under the environment of VrmlPad, we can open these files and perfect the scenes by adding material,texture,sensors,sounds and interpolators.By the node of inline,anchor,we can realize linking or transfering between different scenes.In the end,we can roam the virtual reality system through the movement of the keyboard and mouse in the VRML explorer.In order to approach Reality,a node of collision must be set up to prevent observer from wear or enter impossible visual angle which can’t be observed from object of scene.
        Keywords: Virtual Reality;VRML;roaming;scene;Collision detecting.
