基于BVH驱动的OGRE骨骼动画*

OGRE游戏引擎中的角色动画将模型与骨骼文件进行映射。若想在不借助第三方建模软件重新制作模型和动画的基础上更改现有模型的动作，获取与模型匹配的骨骼数据成为一个难题。提出了一种将标准BVH动作文件解析为XML文件的方法，生成与OGRE模型匹配的骨骼文件，将来源广泛的BVH文件作为动作数据,极大地丰富了OGRE角色动画。实验结果证明，转换后的BVH可以与OGRE中的模型融合起来，从而驱动模型。

Driving OGRE skeleton animation based on BVH

Animation of the role mapped the module and skeleton file in OGRE game engine. It is so hard to restructure the existing animation of the role and acquire the skeleton matched the module without using third-party modeling software to recreate module and animation. This paper presented a method which parsed standard BVH file to XML file, created skeleton file matched OGRE module, by using BVH file which had wide range of source as the animation data, significantly enriched the OGRE animation of the role. The result of the experiment proves that the converted BVH can combine perfectly with OGRE,and drive the model.
