The increasing development and maturity of digital modeling technology makes its application integration in visual communication design possible. This paper proposes a multi-visual 3D animation modeling method by combining visual communication design and digital modeling technology. For the difficulty of drawing curved objects in the modeling process, a luminance interpolation method is used to deal with the surface of objects represented by arbitrary raised polygons. At the same time, Virtools interactive software is used for the design and production of 3D interactive animation. In addition, based on the experimental results, the improved SIFT algorithm with higher matching accuracy and shorter matching time is chosen as the image feature extraction algorithm. By integrating dynamic interaction and modeling, the innovative performance and application of digital modeling technology in visual communication design is realized. In the overall performance of the proposed technology, the difference between the expected and tested values of several indexes is controlled in the interval of [-5,5], which has a high degree of matching with the expected user experience.
