Abstract: The efficiency of design in production of game and movie can be improved
through the reuse of the animation characters data, which can also bring the diversification of
characters. A division method under the skin restriction is presented, which aims at mesh
segmentation——the first step of model reuse. The newis method gets the pre-segmentation
results based on the motion relativity of the skin information firstly, then processes the results by
topologic check and optimization calculation, then obtains the mesh parts adapting to blending of
animation characters finally. After someThe new method is tested given on theusing the models
from game company, the testing results confirmshowed that thise new method is simple and
effective.

Key words: animation characters, mesh segmentation, skin restriction
