一 載入3ds模型

載入3ds模型的技術說明和代碼工程見此博文

http://blog.csdn.net/cq361106306/article/details/41876541

運行以后的效果如下；

二 載入多個模型

此工程是一個Win32 api的工程；
預備在左側顯示模型文件列表；點擊某個模型，在右側載入對應模型；

首先添加列表框；

遍歷文件夾獲取文件列表；

為了定制對列表框的消息處理；增加列表框的窗口過程ListProc；

添加了列表框后把模型往左移動；

float gothicTrans[10] = {?
4, 0 , -30 , ? ? //表示在世界矩陣的位置
0.2 , 0.2 , 0.2 , ? ? ?//表示xyz放大倍數
0 , 0 , 0 , 0 ?//表示旋轉
};

原來是：

0, 0 , -30 , ? ? //表示在世界矩陣的位置

增加了上述代碼以后的效果見上圖；

嘗試在雙擊列表框時載入另一個模型；

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

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

直接掛了；

嘗試先調用CleanUp()再載入另一個模型；提示：

cannot access private member declared in class 'CLoad3DS'

不能訪問私有函數；

那么看來該類在一次運行中只能載入一個3ds模型；

我加了列表框之后的工程可下載；

總結
