一、环境
Visual Studio 2012，DirectX SDK (June 2010)
二、准备
1.环境变量（如没有配置请添加）
变量名：DXSDK_DIR
变量值：D:SoftwareProgramMicrosoft DirectX SDK (June 2010)
这里D:SoftwareProgramMicrosoft DirectX SDK (June 2010)是我的DirectX安装目录，视情况修改即可
三、步骤
1.打开VS2012，创建一个空的Win32 Project
这里的项目名称（Name）可以自定义，项目位置（Location）可能不同，不过没关系，可以不用修改
点击OK，然后点击Next，勾选Empty Project
点击Finish，完成项目创建。
2.打开项目属性（Properites），配置项目的DirectX环境
主要需修改的项：Configuration Properites->VC++ Directories，Configuration Properites->Linker->General，Configuration Properites->Linker->Input
VC++ Directories：（注意后面的分号）
Include Directories项中添加$(DXSDK_DIR)Include;
Library Directories项中添加$(DXSDK_DIR)Libx86;
Linker->Input：添加以下三个lib文件d3d9.lib d3dx9.lib Winmm.lib，添加时注意用分号隔开，如下：
d3d9.lib;d3dx9.lib;Winmm.lib;
Linker->General：AdditionalLibrary Directories项中添加$(DXSDK_DIR)Libx86 （可以不加分号）
点击确定应用以上更改。
3.打开Source.cpp，复制以下代码：
1 #include <d3dx9.h> 2 IDirect3DDevice9* Device=0; 3 LRESULT CALLBACK WndProc(HWND hwnd,UINT msg,WPARAM wParam,LPARAM lParam) 4 { 5 switch(msg) 6 { 7 case WM_DESTROY:PostQuitMessage(0);break; 8 case WM_KEYDOWN: 9 if(wParam==VK_ESCAPE)DestroyWindow(hwnd);break; 10 } 11 return DefWindowProcW(hwnd,msg,wParam,lParam); 12 } 13 bool Init(HINSTANCE hInstance,int width,int height,bool windowed,D3DDEVTYPE devType,IDirect3DDevice9** device) 14 { 15 WNDCLASSW wc; 16 wc.cbClsExtra=0; 17 wc.cbWndExtra=0; 18 wc.hbrBackground=(HBRUSH)GetStockObject(WHITE_BRUSH); 19 wc.hCursor=LoadCursorW(0,IDC_ARROW); 20 wc.hIcon=LoadIconW(0,IDI_APPLICATION); 21 wc.hInstance=hInstance; 22 wc.lpfnWndProc=(WNDPROC)WndProc; 23 wc.lpszClassName=L"Direct3D"; 24 wc.lpszMenuName=0; 25 wc.style=CS_HREDRAW|CS_VREDRAW; 26 if(!RegisterClassW(&wc)) 27 { 28 MessageBoxW(0,L"Register Failed",0,0); 29 return false; 30 } 31 32 HWND hwnd=0; 33 hwnd=CreateWindowW(L"Direct3D",L"Direct3D",WS_OVERLAPPEDWINDOW,0,0,width,height,0,0,hInstance,0); 34 if(!hwnd) 35 { 36 MessageBoxW(0,L"CreateWindow Failed",0,0); 37 return false; 38 } 39 ShowWindow(hwnd,SW_SHOW); 40 UpdateWindow(hwnd); 41 42 HRESULT hr; 43 IDirect3D9* d3d9; 44 d3d9=Direct3DCreate9(D3D_SDK_VERSION); 45 46 int vp=0; 47 D3DCAPS9 caps; 48 d3d9->GetDeviceCaps(D3DADAPTER_DEFAULT,devType,&caps); 49 if(caps.DevCaps & D3DDEVCAPS_HWTRANSFORMANDLIGHT) 50 vp=D3DCREATE_HARDWARE_VERTEXPROCESSING; 51 else vp=D3DCREATE_SOFTWARE_VERTEXPROCESSING; 52 53 D3DPRESENT_PARAMETERS d3dapp; 54 d3dapp.AutoDepthStencilFormat=D3DFMT_D24S8; 55 d3dapp.BackBufferCount=1; 56 d3dapp.BackBufferFormat=D3DFMT_A8R8G8B8; 57 d3dapp.BackBufferHeight=height; 58 d3dapp.BackBufferWidth=width; 59 d3dapp.EnableAutoDepthStencil=true; 60 d3dapp.Flags=0; 61 d3dapp.FullScreen_RefreshRateInHz=D3DPRESENT_RATE_DEFAULT; 62 d3dapp.hDeviceWindow=hwnd; 63 d3dapp.MultiSampleQuality=0; 64 d3dapp.MultiSampleType=D3DMULTISAMPLE_NONE; 65 d3dapp.PresentationInterval=D3DPRESENT_INTERVAL_IMMEDIATE; 66 d3dapp.SwapEffect=D3DSWAPEFFECT_DISCARD; 67 d3dapp.Windowed=windowed; 68 hr=d3d9->CreateDevice(D3DADAPTER_DEFAULT,devType,hwnd,vp,&d3dapp,device); 69 if(FAILED(hr)) 70 { 71 MessageBoxW(0,L"CreateDevice Failed",0,0); 72 d3d9->Release(); 73 return false; 74 } 75 d3d9->Release(); 76 return true; 77 } 78 int EnterMsgLoop(bool (*ptr_display)(float TimeDelta)) 79 { 80 MSG msg; 81 ZeroMemory(&msg,sizeof(MSG)); 82 float LastTime=(float)GetCurrentTime(); 83 while(msg.message!=WM_QUIT) 84 { 85 if(PeekMessageW(&msg,0,0,0,PM_REMOVE)) 86 { 87 TranslateMessage(&msg); 88 DispatchMessageW(&msg); 89 } 90 else 91 { 92 float CurTime=(float)GetCurrentTime(); 93 float TimeDelta=(float)(CurTime-LastTime)*0.001f; 94 ptr_display(TimeDelta); 95 LastTime=CurTime; 96 } 97 } 98 return msg.wParam; 99 } 100 bool Setup() 101 { 102 return true; 103 } 104 void Cleanup() 105 { 106 107 } 108 bool Display(float TimeDelta) 109 { 110 if(Device) 111 { 112 Device->Clear(0,0,D3DCLEAR_TARGET|D3DCLEAR_ZBUFFER,0x00000000,1.0f,0); 113 Device->Present(0,0,0,0); 114 } 115 return true; 116 } 117 int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE prevInstance,PSTR cmdLine,int showCmd) 118 { 119 if(!Init(hInstance,640,480,true,D3DDEVTYPE_HAL,&Device)) 120 MessageBoxW(0,L"Init Failed",0,0); 121 if(!Setup())MessageBoxW(0,L"Setup Failed",0,0); 122 EnterMsgLoop(Display); 123 Cleanup(); 124 Device->Release(); 125 return 0; 126 }
点击Local Windows Debugger编译项目，运行结果如下：
至此，第一个Direct3D程序已经完工。
