虛擬現實技術是目前國內外計算機應用研究的熱點，其實時的三維空間表現力和逼真
的沉浸感，將極大地推動計算機仿真技術的發展。該文詳述了虛擬現實技術的主要特征及其應用，并介紹了虛擬現實建模語言VRML 的基本格式和特點，討論了基于VRML 構建室內虛擬環境的常用技術。最后，利用支持VRML 的3DS MAX 軟件實現了三維復雜物體建模，通過Java/JavaScript 實現了用戶與室內虛擬環境之間的動態交互。
關鍵詞：虛擬現實；建模；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
