虛擬現(xiàn)實技術(shù)是目前國內(nèi)外計算機(jī)應(yīng)用研究的熱點(diǎn)，其實時的三維空間表現(xiàn)力和逼真
的沉浸感，將極大地推動計算機(jī)仿真技術(shù)的發(fā)展。該文詳述了虛擬現(xiàn)實技術(shù)的主要特征及其應(yīng)用，并介紹了虛擬現(xiàn)實建模語言VRML 的基本格式和特點(diǎn)，討論了基于VRML 構(gòu)建室內(nèi)虛擬環(huán)境的常用技術(shù)。最后，利用支持VRML 的3DS MAX 軟件實現(xiàn)了三維復(fù)雜物體建模，通過Java/JavaScript 實現(xiàn)了用戶與室內(nèi)虛擬環(huán)境之間的動態(tài)交互。

Abstract：Virtual Reality technique is the attractive domain for computer application research all over the world, its real-time three dimensional expressive force and realistic immersion will
greatly improve the computer simulation technique. This paper details the main characters and
application of Virtual Reality technique, and introduces the basic format and characters of Virtual Reality Modeling Language. the frequently used technique in building the virtual environment inside house based on VRML is discussed . At last, modeling on the three dimensional complicated object can be realized based on 3DS MAX software which support VRML, and dynamic interaction between user and virtual environment inside house can be accomplished by Java/JavaScript.
Key words：virtual reality, modeling, interaction
