The final purpose of this study is to find a method of projecting the characteristics and attractiveness of actual actor's facial expressions onto avatars based on facial capture technology to improve facial expressions of digital actors. Metaverse performances can create various situations without time and space constraints, providing new cultural experiences to the audience watching them. However, it is also true that in current metaverse performances, digital actors' facial expressions are partially vulnerable to conveying emotions. It also acts as one of the factors that interfere with the audience's immersion. One of the problems is that not all avatars have unique characteristics outwardly, so the lack of differentiation is also one of the problems. To overcome these limitations, we propose a method of modeling the actual actor's facial expressions with 3D scans to create a morph target and applying it to avatars using facial capture technology.

Shape morphing is the process of transforming a source shape, through intermediate shapes, into a target shape. Two main problems to be considered in three dimensional shape morphing are vertex correspondence and path interpolation. In this paper, an approach which uses the linear interpolation of the Laplacian coordinates of the source and target meshes is introduced for the determination of more plausible path when two topologically identical shapes are morphed. When two shapes to be morphed are different in shape and topology, a new method which combines shape deformation theory based on Laplacian coordinate and mean value coordinate with distance field theory is proposed for the efficient treatment of vertex correspondence and path interpolation problems. The validity and effectiveness of the suggested method was demonstrated by using it to morph large and complex polygon models including male and female whole body models.
