Connecting archived short segmental action data

　When we shoot MR-PreViz, there might be cases in which a director and crews need to add new CG motion data to a scene. In order to deal with such situations, we propose a method that enables crews to rebuild action sequences on the spot.
　In our method, we captured action sequences that were split into action building blocks. and some of them were combined together as a new action sequence.
　Action building blocks were defined under an action coordinator's advice. Then, each action sequence was played by actors/actress and the data was recorded by using motion capture and 3D video system. Captured data were stored in an archive.
　As the first step of our research, action scenes were assumed to be swordfight plays. Action building blocks are stored as short action data including just one action. All action building blocks began and ended with the same pose such that a character's action sequences could be constructed by splicing action building blocks smoothly.
　As noted above, we assume to use two different types of action data formats, motion capture and 3D video data. The former is jointed by using bone information and the latter is by using the center of gravity determined by mesh information.
