C++網格變得動畫時，他們不是也假設

我有兩個網格。其中一個是動畫，另一個不是動畫。當我渲染它們時，無生命的網格以與動畫網格動畫相同的方式獲得動畫。
所以，讓動畫網格走到左邊比回來，我無生命的網格做同樣的事情！
這是我的無生命網格的代碼類。

我有一種感覺你的問題存在您提供的類之外。您可以包含您在StaticMesh對象上執行哪些操作的示例嗎？ – MrGomez 2010-12-06 00:34:37

的anination來自一個轉換矩陣。您將其直接傳遞給設備（如果使用固定功能）或着色器/效果。在矩陣設置後繪製的所有網格都將經歷相同的變換。所以，如果你想讓一個網格保持無生命，你必須在繪製網格之前改變變換。

僞代碼：

SetTransform(world* view * projection); 
DrawMesh(); 
SetTransform(identity * view * projection); 
DrawMesh();
