A Study on 3D Motion Design Expression Techniques for 2D Facial Images

The motion that can be applied to 2D graphics is made on a plane, which is monotonous and limited in visual expression compared to 3D motion design.With the rapid expansion of video online platforms, there is a need for high-quality motion design quickly and easily in terms of production, so this paper proposes 3D motion design by applying only optical illusion theories such as perspective and simple motion functions to 2D graphics.Based on the principle that the human eye recognizes 3D objects, we propose and verify a technique that arranges each element of a character's face in layers and expresses 3D motion by positioning and scaling, and confirm that it is possible to realize 3D rotational motion in 2D, resulting in a 3D motion design with high visual immersion.The proposed technique can expand the possibilities of expression and information delivery in video contents such as motion graphics, and can be advantageous in terms of reducing production time and cost, and is expected to be utilized in actual production in the field or as a basic research and educational material related to content visual expression and motion design.
