MFC D3D 导入模型(.X文件)

添加头文件

#include <d3d9.h>
#include <d3dx9.h>
#pragma comment(lib, "d3d9.lib")
#pragma comment(lib, "d3dx9.lib")

定义变量

private:
	IDirect3D9 *pDirect9;
	IDirect3DDevice9 *pDevice9;

	DWORD dwNumber;
	LPD3DXMESH pMesh;
	LPDIRECT3DTEXTURE9* g_pTexture;
	D3DMATERIAL9* g_pMaterials;

使用类向导添加WM_TIMER跟WM_CLOSE

在OnInitDialog()函数里面添加

pDirect9 = Direct3DCreate9(D3D_SDK_VERSION);
	if (pDirect9)
	{
		D3DPRESENT_PARAMETERS dp;
		dp.BackBufferWidth = 640;                                   //后备缓冲表面的宽度（以像素为单位）

		dp.hDeviceWindow = m_hWnd;

		dp.FullScreen_RefreshRateInHz = D3DPRESENT_RATE_DEFAULT;    //刷新率，设定D3DPRESENT_RATE_DEFAULT使用默认刷新率    
		dp.PresentationInterval = D3DPRESENT_INTERVAL_IMMEDIATE;    //属于D3DPRESENT成员，又有两个常用标志，其余请查SDK：D3DPRESENT_INTERVAL_IMMEDIATE——立即交换.D3DPRESENT_INTERVAL_DEFAULT——D3D选择交换速度，通常等于刷新率 
		pDirect9->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, m_hWnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING, &dp, &pDevice9);

		LPD3DXBUFFER pAdjacency;

定义函数：

D3DLIGHT9 InitDirectionalLight(D3DXVECTOR3* direction, D3DXCOLOR* color)
{
	D3DLIGHT9 light;
	::ZeroMemory(&light, sizeof(light));

	light.Type = D3DLIGHT_DIRECTIONAL;

	light.Diffuse = *color;
	light.Specular = *color * 0.6f;
	light.Direction = *direction;

	return light;
}

定时器函数：

if (pDevice9){
		static float y = 0.0f;
		D3DXMATRIX yRot;
		D3DXMatrixRotationY(&yRot, y);
		y += 20.0f;

		if (y >= 360.0f){
			y = 0.0f;
		}
			
		D3DXMATRIX World = yRot;
		pDevice9->SetTransform(D3DTS_WORLD, &World);
		pDevice9->Clear(0, NULL, D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER, D3DCOLOR_XRGB(255, 0, 0), 1.0f, 0);
		pDevice9->BeginScene();
		for (int i = 0; i < dwNumber; i++){
			pDevice9->SetMaterial(&g_pMaterials[i]);
			pDevice9->SetTexture(0, g_pTexture[i]);
			pMesh->DrawSubset(i);
		}
		pDevice9->EndScene();

		pDevice9->Present(NULL, NULL, m_hWnd, NULL);
	}

退出函数

if (pDevice9){
		pDevice9->Release();
	}

	if (pDirect9){
		pDirect9->Release();
	}
	if (g_pTexture){
		delete[] g_pTexture;
	}
	if (g_pMaterials){
		delete[] g_pMaterials;
	}

	KillTimer(0);
