With the deep popularization of digital media in the field of visual design, digital visual design has also been significantly developed in several industries. The research applies digital visual design to animation art, based on the basic principles of display space design, optimizes the rendering of animation art space and dynamic updating of the scene through multi-resolution LOD technology, and improves the LOD loading method through the entropy of image information, to construct the animation art space display model based on Unity3D. Taking the scene of the animation “City in the Sky” as an example, the animation art space created by the model in this paper is analyzed by example. The color and lighting of the space are analyzed to confirm the effect of this paper’s model by studying the satisfaction of visitors with the experience of the animation art space. The color tone of the animation art space created by the model in this paper is mostly warm. The color brightness is concentrated in the middle and high brightness areas, the color degree is concentrated in the middle and low color degree areas, and the color distribution is more harmonious. The lighting uniformity in the seven areas of the animation art space is not less than 0.8, and the illumination degree of the exhibition area and the non-exhibition area is in line with the lighting standards of the exhibition hall. Visitors’ satisfaction with the animation art space is higher than 4 points. The animation art space created by the model in this paper is of exceptional quality, as can be seen.
