For the environmental artistic design, the traditional mode of environmental artistic design is broken through after the emergence of computer technology and virtual reality technique, which makes the scheme and application of virtual reality technique in environmental artistic design to own more practical value. In this paper, the virtual reality technique and its practical application in environmental artistic design are set forth, and the profound influence on the actual design by the virtual reality technique is studied with expectation of enlightenment for broadening the thought of environmental artistic design.展开更多
