With the rapid development of information technology, virtual reality technology has become a major innovation in the field of environmental art and design. This article delves into the application of VR technology in environmental art design and its positive impact. By integrating sensing technology, computer technology, human interaction technology, and artificial intelligence technology, VR technology provides designers with an immersive 3D design environment, greatly enhancing the interactivity and realism of design. The study compared the working hours, customer satisfaction, and design costs of museum design, interior design, park landscape design, and urban planning design before and after the application of VR technology. It was found that VR technology significantly shortened the design cycle, improved customer satisfaction, and significantly reduced design costs. These data indicate that VR technology not only improves design efficiency and enhances customer experience, but also achieves effective cost savings. The conclusion of this article emphasizes that the application of virtual reality technology has brought revolutionary changes to environmental art design, promoted innovative development in design, and foreshadowed the future trend of the design industry.
