| The technology of virtual reality is stepping from mirage into reality, from laboratories into our daily life. If the greatest revolution is the spread of digital technology in the 21st century, the greatest achievement is virtual reality. And this technology deeply affects and charges our life, dividing into two different sections: real and unreal (virtual) world. The two mingle together, and catch the flash of human intelligence and creativity. Probing its origins and mysteries is a part of job.It is increasingly developing due to its dynamic. From the earliest VRML (Virtual Reality Modeling Language) to present X3D, changes make us not sleep a wink. However, they stay much the same. Being a classical programming language, VRML is an origin of advanced virtual technology. In view of it, the author stresses technical details (in the chapter â…¢) , examines the most advanced technology and structure platform (software), moreover, gives detailed explanation in practice (in the chapter IV).Besides, the author holds a view that with the development of virtual reality technology, virtual aesthetic research hasn't kept up. Some traces can be found from aesthetics of traditional art and design works, yet virtual aesthetics has too many difficulties to cope with the traditional one. Thus, exploring its aesthetic features is a fresh topic(in the chapter â…¡).Through this paper, theory and practice are integrated. Researches, design examples and pictures are all provided ideas and methods for researchers.
