摘  要
 
 基于虛擬現(xiàn)實(shí)技術(shù)的網(wǎng)絡(luò)學(xué)習(xí)環(huán)境主要是指利用虛擬現(xiàn)實(shí)技術(shù)構(gòu)建一個(gè)模擬的學(xué)習(xí)環(huán)境，類似于虛擬校園與虛擬教室。采用3D建模技術(shù)構(gòu)建一個(gè)虛擬學(xué)習(xí)環(huán)境，利用虛擬現(xiàn)實(shí)中VRML語言的特點(diǎn)，使該環(huán)境具有空間變換，增強(qiáng)它的真實(shí)感，以加強(qiáng)學(xué)習(xí)者在學(xué)習(xí)過程中的情感認(rèn)知，使學(xué)習(xí)者有置身其中的感覺，以增強(qiáng)學(xué)習(xí)效果。
 文章對(duì)VRML 結(jié)合3DS MAX在網(wǎng)絡(luò)教學(xué)中實(shí)現(xiàn)虛擬學(xué)習(xí)環(huán)境的技術(shù)進(jìn)行了探索，并以實(shí)例的形式討論了虛擬教學(xué)環(huán)境靜態(tài)建模方法及教學(xué)過程中動(dòng)態(tài)仿真等的關(guān)鍵技術(shù)問題。首先用相應(yīng)的軟件進(jìn)行三維建模，突顯出真實(shí)性；再結(jié)合VRML節(jié)點(diǎn)，實(shí)現(xiàn)更多的交互性，如信息提示、視頻點(diǎn)播、聲音控制等等，并盡可能的達(dá)到真實(shí)的教學(xué)環(huán)境的效果。
 該網(wǎng)絡(luò)學(xué)習(xí)環(huán)境為教育技術(shù)的應(yīng)用開辟了新的領(lǐng)域。

ABSTRACT

 The network learning environment which is based on the virtual reality technology means using virtual reality technology to build a simulated learning environment, similar to virtual campus and virtual classroom. In order to transform the environment space and enhance its realism, we use 3D modeling techniques to build a virtual learning environment and use virtual reality modeling language features. And thus it strengthens the learners’ emotional awareness in the learning process and makes them feel they were in real environment. So it enhances the learning effects.
 The article makes an exploration on using VRML combined with 3DS MAX to construct the virtual network learning environment and discusses the key technical problems in the form of examples on static modeling in the process of dynamic simulation in the virtual learning environment and teaching methods. First, use the corresponding three-dimensional modeling software to highlight the truth. Second, we combine with VRML nodes to achieve more interactive, such as information tips, video frequency broadcast, sound control, and so on, and as far as possible to achieve real teaching and learning environment results.
 The network learning environment for the application of educational technology has opened up new areas.
