Diversity of expression in 3D digital media animation creation

Abstract

Abstract At present, the theoretical research on the creation of 3D animation in the digital media era is in the ascendant. In this paper, starting from the grid model of 3D animation, a 3D animation intermediate frame interpolation algorithm based on the 3D grid model is proposed. The deformation gradient vector is extracted through the triangular slice when calculating the affine transformation between neighboring keyframes. Using the system of super-definite equations to solve the intermediate frame mesh, the interconversion equations are constructed, and the intermediate frame deformation scale vectors are computed to generate the corresponding 3D animation sequences. Using the OpenGL 3D graphics method, the image model, color and light of the animation are processed, and combined with the rotating animation design, the all-around construction of 3D animation is realized. Digital media technology is being explored through its diverse expressions. The characteristics of animation creation and the actual presentation effect of animation creation applied in movies are analyzed through experiments, and the influence of the animation audience’s willingness to watch is investigated. The results show that the mean value of color saturation of animated films ranges between [0.1, 0.8], and the mean value of color saturation is higher than that of non-animation. The starting value of the quantile coefficient of the rotated animation presentation was 0.85, and subsequently remained around 0.5, and there was significance at 1% level for the whole stage, which had a positive effect on the presentation of the animated movie.
