蒙皮约束下的动画角色模型分割方法

动画角色的数据重用可以提高游戏与动画的制作效率并丰富角色类型。针对模型数据重用的首要步骤——动画角色的三维网格分割问题,提出了一种蒙皮约束下的分割方法,利用蒙皮信息的运动相关性,产生依据该信息的部件预分割,在预分割结果上进行拓扑检查并调整,进而再对切口处进行优化处理,最终产生适合动画角色融合的网格部件。最后给出在用游戏公司提供的真实数据上对新方法进行的了测试,结果,证明了表明该新方法的简洁有效并说明了其适用范围。

Mesh segmentation of animation characters under the skin restriction

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.
