此project是一个Win32 api的project；
预备在左側显示模型文件列表。点击某个模型，在右側加载相应模型；

首先加入列表框；

遍历目录获取文件列表；

为了定制对列表框的消息处理。添加列表框的窗体过程ListProc。

加入了列表框后把模型往左移动。

float gothicTrans[10] = { 
4, 0 , -30 ,     //表示在世界矩阵的位置
0.2 , 0.2 , 0.2 ,      //表示xyz放大倍数
0 , 0 , 0 , 0  //表示旋转
};

原来是：

0, 0 , -30 ,     //表示在世界矩阵的位置

添加了上述代码以后的效果见上图。

尝试在双击列表框时加载还有一个模型。

case WM_COMMAND :
{
          if (LOWORD (wParam) == ID_LIST && HIWORD (wParam) == LBN_DBLCLK)
          {

//gothicLoader->CleanUp();
gothicLoader->Import3DS(&gothicModel, "Data/3ds/middleTree.3DS");
 }
 return 0;
}

直接挂了。

尝试先调用CleanUp()再加载还有一个模型；提示：

cannot access private member declared in class 'CLoad3DS'

不能訪问私有函数；

那么看来该类在一次执行中仅仅能加载一个3ds模型；

我加了列表框之后的project可下载；
