Title (EN) METHOD FOR GENERATING INFORMATION ABOUT SHOULDER MOVEMENT OF 3D VIRTUAL CHARACTER
(FR) PROCÉDÉ DE GÉNÉRATION D'INFORMATIONS À PROPOS DU MOUVEMENT D'ÉPAULE D'UN PERSONNAGE VIRTUEL 3D
(KO) 3D 가상 캐릭터의 어깨 움직임 정보 생성방법
Abstract:
(EN) The present invention pertains to a method for generating information about the shoulder movement (rotation) of a 3D virtual character, comprising: a step of converting rotation angle information of joints obtained by measuring movements associated with shoulder elevation at every elevation angle of designated degrees on the coronal plane, the scapular plane and the sagittal plane into quaternions (q θ,φ) for elevation plane angles (θ) and elevation angles (φ); a step of setting quaternions for interpolation, among the converted quaternions, and interpolation weights for arbitrary elevation plane angles and elevation angles; and a step of calculating rotation information of each joint in an interpolated frame by applying spherical interpolation to the set quaternions for interpolation.
(FR) La présente invention concerne un procédé de génération d'informations à propos du mouvement (rotation) d'épaule d'un personnage virtuel 3D, comprenant : une étape de conversion d'informations d'angle de rotation d'articulations obtenues par la mesure de mouvements associés à une élévation de l'épaulement à chaque angle d'élévation ayant un nombre de degrés désigné sur le plan coronal, le plan scapulaire et le plan sagittal en quaternions (q θ,φ) pour les angles de plan d'élévation (θ) et les angles d'élévation (φ) ; une étape de définition de quaternions pour l'interpolation, parmi les quaternions convertis, et de poids d'interpolation pour les angles de plan d'élévation et les angles d'élévation arbitraires ; et une étape de calcul d'informations de rotation de chaque articulation dans une trame interpolée par application d'une interpolation sphérique aux quaternions définis pour l'interpolation.
(KO) 본 발명은 3D 가상 캐릭터의 어깨 움직임(회전) 정보를 생성하는 방법에 관한 것으로, 어깨의 거상에 대한 움직임을 관상면, 견갑면, 시상면 상에서 지정된 각도의 거상각 마다 측정하여 얻어진 관절들의 회전각 정보들을 거상면 각도(θ)와 거상각(φ)에 대한 사원수(quaternion: q θ,φ)로 변환하는 단계와, 상기 변환된 사원수들 중 임의의 거상면 각도 및 거상각에 대해 보간 대상 사원수 및 보간 가중치를 설정하는 단계와, 상기 설정된 보간 대상 사원수들에 구면 보간을 적용하여 보간 프레임 상의 각 관절 회전정보를 계산하는 단계;를 포함함을 특징으로 한다.
