虽然.X文件不再被广泛支持，但其数据定义仍具有相当的参考价值和意义~
本篇简单实现了.X网格的加载及渲染，意在服务于后续章节，感兴趣的朋友可以简单参考一下~
DX9.0对.X文件提供了相当丰富的支持，包括高级骨骼动画的解析及渲染。
DX10之后，.X开始渐渐淡出人们的视野，取而代之的是各种自定义的网格数据文件。

注释比较详尽，完全参考了《龙书》里的例子。
简单说明一下D3DXMATERIAL结构。如下为SDK中关于D3DXMATERIAL的结构定义：
typedef struct _D3DXMATERIAL
{
D3DMATERIAL9 MatD3D;
LPSTR pTextureFilename;
} D3DXMATERIAL;
该结构专门用于.X中材质信息读取，其中MatD3D是真正的材质信息，pTextureFilename则是此材质关联的纹理名称，需要调用D3DXCreateTextureFromFile来生成真正的纹理对象。相关的API说明可以参看这篇帖子：http://space.cnblogs.com/group/topic/32953/
如果大家还有什么不明白的地方，可以参看龙书，也可以在下方留言，我会尽量给予详尽的解答 ^ ^
