We focus on creating cat jump animations by using 3DCG. In this paper, we propose a method to generate an appropriate jump motion under various situations. Our proposed method is able to generate jump animations corresponding a positional relationship between the initial position of the cat and the target point, which the user specifies. By experiments for comparing a conventional creating method and our tool, the experiment result shows our method is more efficient than a traditional method to create cat jump animation. It enables to reduce the creating cost and create the proper jump action by using our tool.
