即使使用动作捕捉设备或动作编辑工具，创建长动作序列也是一项耗时的任务。在本文中，我们提出了一种通过组合基本运动剪辑来创建长运动序列的系统。用户被要求首先在时间线上输入动作。然后系统会自动生成连续且自然的运动。我们的系统采用四种运动合成方法：运动过渡、运动连接、运动适应和运动合成。基于动画角色的脚和地面之间的约束以及输入运动的时序，为每对重叠或顺序运动确定适当的方法。当用户改变运动剪辑的排列时，系统交互地改变输出运动。或者，用户可以使系统尽快执行输入动作，以便其平滑地跟随先前的动作。使用我们的系统，用户可以利用现有的动作剪辑。由于整个过程是自动的，即使是新手也可以轻松使用我们的系统。原型系统展示了我们方法的有效性。
Creating long motion sequences is a time‐consuming task even when motion capture equipment or motion editing tools are used. In this paper, we propose a system for creating a long motion sequence by combining elementary motion clips. The user is asked to first input motions on a timeline. The system then automatically generates a continuous and natural motion. Our system employs four motion synthesis methods: motion transition, motion connection, motion adaptation, and motion composition. Based on the constraints between the feet of the animated character and the ground, and the timing of the input motions, the appropriate method is determined for each pair of overlapped or sequential motions. As the user changes the arrangement of the motion clips, the system interactively changes the output motion. Alternatively, the user can make the system execute an input motion as soon as possible so that it follows the previous motion smoothly. Using our system, users can make use of existing motion clips. Because the entire process is automatic, even novices can easily use our system. A prototype system demonstrates the effectiveness of our approach.
