Abstract: With the rapid development of computer graphics and the animation industry, it becomes an important way to produce animation works by using computer to realize motion editing and retargeting and build the character motion library for reuse. This paper introduces a character motion trajectory extraction and retargeting method. This method can realize the reuse of the character motion by recording the motion trajectory of a character’s end joint, using certain normalization rules to extract the trajectory and build a character motion library, and retargeting to another character by a CCD IK solver. It proves that such method is ideal.
Key words: motion retargeting, motion trajectory, inverse kinematics
摘要: 随着计算机图形学和动漫产业的快速发展,通过计算机实现运动编辑和运动重定向技术,形成角色动作库进行重复利用,成为快速生产动漫作品的一个重要手段。提出了一种角色运动轨迹提取及重定向的方法。该方法通过记录角色末端关节的运动轨迹,通过一定的归一化规则提取建立角色运动轨迹库,利用CCD逆向运动学解算器重定向至另外一个角色,实现角色动作的重复利用,达到了较为理想的效果。
关键词: 运动重定向, 运动轨迹, 逆向运动学
