这里的骨骼蒙皮动画特指skinnd mesh，也叫骨骼动画。无论是合金装备，波斯王子，还是魔兽世界，到处都是骨骼动画技术的运用。用它塑造了各种各样，栩栩如生的生物。其中，人类体格的骨骼动画运用最为广泛。现在让我们一步一步揭开它神秘的面纱。

动画是由若干静态画面，快速交替显示而成。因人的眼睛会产生视角暂留，对上一个画面的感知还末消失，下一张画面又出现，就会有动的感觉。计算机图形学中的动画也同样遵循着这一本质的原理。只不过不同于传统动画的手绘和拍摄，Ogre图形引擎可以通过自动或半自动的方式实时产生并播放动画图片。

在Ogre中，并没有要求你一定要把最终的显示画面渲染到图形显示设备上。换句话说，Ogre最终渲染到帧缓存的结果（颜色数据），既可以在显示器上面展示也可以输送到其他渲染目标。在这里，渲染目标的概念是一个用来保存渲染结果（二维信息）的存储区域，它既可以在显存中也可以在AGP[1]的共享储存区域中。

在Ogre中所有被用来帮助程序进行渲染工作的东西都被称为资源，其中包括模型，骨骼，材质，GPU程序等。而Ogre对这些资源文件和数据载入的组织策略被称为资源管理。

在这里我可以大胆的断言，目前在地球上，所有的图形引擎都在使用场景图（Scene Graph）的概念来组织管理它里面可渲染的物体（我甚至怀疑外星人也在用这个）。 场景图在图形引擎中的地位是毋庸置疑的，它不仅提供了对用户在空间中查找和搜索物体提供了高速的优化，并且针对程序库（对我们而言就是Ogre）的渲染需要，提供了相应的搜索、排序以及剔除功能。在某些时候也被用来进行碰撞检测。在一些具体的设计里面，场...
