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.
