使用cAnimMesh類包含3個步驟，首先在回調(diào)函數(shù)OnCreateDevice()中創(chuàng)建cAnimMesh類的實例：
g_anim_mesh = new cAnimMesh();
V_RETURN(g_anim_mesh->create(pd3dDevice, L"emr.x"));
接著在回調(diào)函數(shù)OnFrameRender()中渲染網(wǎng)格模型：
g_anim_mesh->render(&g_mat_world, fElapsedTime *
0.001);
最后在回調(diào)函數(shù)OnDestroy()中釋放網(wǎng)格模型:
g_anim_mesh->destroy();
