Summary:A method for transferring a face shape change for face animation according to an embodiment of the present invention includes the steps of: receiving edit data for a piece of expression data among a plurality of pieces of expression data; performing geometry smoothing on the plurality of pieces of expression data; converting the plurality of pieces of smoothed expression data from a first space to a second space; applying the edit data to the remaining unedited expression data among the plurality of pieces of expression data converted to the second space; and converting, to the first space, the plurality of pieces of expression data to which the edit data has been applied. Un procédé de transfert d'un changement de forme de visage pour animation faciale selon un mode de réalisation de la présente invention comprend les étapes consistant : à recevoir des données d'édition pour un élément de données d'expression parmi une pluralité d'éléments de données d'expression ; à réaliser un lissage de géométrie sur la pluralité d'éléments de données d'expression ; à convertir la pluralité d'éléments de données d'expression lissée d'un premier espace à un second espace ; à appliquer les données d'édition aux données d'expression non éditées restantes parmi la pluralité d'éléments de données d'expression converties dans le second espace ; et à convertir, dans le premier espace, la pluralité d'éléments de données d'expression auxquelles les données d'édition ont été appliquées. 본 발명의 일 실시예에 따른 얼굴 애니메이션을 위한 얼굴 형태 변화 전사 방법은, 복수의 표정 데이터 중에서 어느 하나의 표정 데이터에 대한 편집 데이터를 입력받는 단계; 상기 복수의 표정 데이터에 대한 지오메트리 평탄화를 수행하는 단계; 평탄화된 상기 복수의 표정 데이터를 제1 공간에서 제2 공간으로 변환하는 단계; 상기 제2 공간으로 변환된 복수의 표정 데이터 중 편집되지 않은 나머지 표정 데이터에 상기 편집 데이터를 적용하는 단계; 및 상기 편집 데이터가 적용된 복수의 표정 데이터를 상기 제1 공간으로 변환하는 단계를 포함할 수 있다.
