Digital media art mainly studies the methods and techniques of using information technology for artistic processing and creation. Through theoretical study, professional skills training, etc., people can master the use of digital media software and have the ability to use digital technology to perform artistic processing on various types of works. This article is aimed at studying the art analysis of digital painting media based on wireless networks. In the past few years, as the country pays more and more attention to it, the level of science and technology in our country is constantly improving. At this stage, it has entered a new media environment using digital media. In the method part, this article proposes wireless network technology. It is believed that digital painting and traditional painting are very different in expression form and artistic concept. Digital painting transforms the static expression of traditional painting into digital form, so that they are no longer limited to the static expression of the plane. In the algorithm part, this article uses the algorithm of virtual technology to make a long-term plan for the development of digital painting media art. The experimental results of this paper show that the proportions of digital media art materials in practical technology, visual experience, and Chinese painting are 50%, 61%, and 73%, respectively, and their proportions are constantly increasing, occupying an important role in the field of digital media art.
