Through in-depth observation and quantitative analysis of China's digital art, combined with the current development of computer graphics hardware and 3D animation technology, this paper carries out the research of 3D animation art technology based on programmable graphics hardware. The use of 3D animation technology to produce digital art, explores new technologies to achieve traditional animation methods, produce digital art, not only improve efficiency, but also make the animation of the performance space expand to three-dimensional space. With the help of 3D animation technology, digital art will keep pace with the times and present its own distinctive characteristics. Under the influence of 3D animation technology, digital art has undergone a new development. Combining traditional animation art with 3D animation technology, it has not only formed a new form of animation art expression, but also expanded a new field of creation for animation art. Corresponding to the aesthetics and market requirements of the digital age, it extracts the means and methods that combine the cultural essence of traditional digital art and the aesthetic characteristics of film and television with modern high technology, and finally form a new production mode such as the basic technology and creation program of 3D digital art.
