DX初学咋练-配置环境及初次运行（vs2010/dx9.0） 纠结了两天了 dx环境配置及运行一个小例子 终于解决了 新建一个 win32项目 选择 “空项目”（如果给建成win32控制台的项目了 那就要更改一些其他的属性 最后说） 点击项目-属性-VC+目录 添加包含目录和库目录$(DXSDK_DIR)Include$(DXSDK_DIR)Libx86(添加的时候 不要忘了加英文标点符号; 例如 原来是$(VCInstallDir)include;$(VCInstallDir)atlmfcinclude;$(WindowsSdkDir)include;$(FrameworkSDKDir)include在这个的最后添加 ;$(DXSDK_DIR)Include ) 然后再 点击连接器-输入 在附加依赖项上添加 需要的.lib到这就配置完了下面是在 /page/M0/S655/655240.html 上找的一个dx 的例子。 1 #include 2 #include 3 #include 4 LPDIRECT3D9 g_pD3D; 5 LPDIRECT3DDEVICE9 g_pd3dDevice; 6 LPDIRECT3DVERTEXBUFFER9 g_pVB; 7 struct CUSTOMVERTEX 8 FLOAT x, y, z; 9 DWORD color; 10 ; 11 #define D3DFVF_CUSTOMVERTEX (D3DFVF_XYZ|D3DFVF_DIFFUSE) 12 HRESULT InitObject() 13 14 CUSTOMVERTEX triangle = 15 16 -1.0f,-1.0f, 0.0f, 0xffff0000, , 17 1.0f,-1.0f, 0.0f, 0xff0000ff, , 18 0.0f, 1.0f, 0.0f, 0xffffffff, 19 ; 20 if (FAILED(g_pd3dDevice-CreateVertexBuffer(3*sizeof(CUSTOMVERTEX),0, D3DFVF_CUSTOMVERTEX, D3DPOOL_DEFAULT, &g_pVB, NULL) 21 return E_FAIL; 22 VOID* pVertices; 23 if (FAILED(g_pVB-Lock(0,sizeof(triangle), &pVertices, 0) 24 return E_FAIL; 25 memcpy(pVertices, triangle, sizeof(triangle); 26 g_pVB-Unlock(); 27 return S_OK; 28 29 HRESULT InitD3D(HWND hWnd) 30 31 g_pD3D = Direct3DCreate9(D3D_SDK_VERSION); 32 if (NULL = g_pD3D) 33 return E_FAIL; 34 D3DPRESENT_PARAMETERS d3dpp; 35 ZeroMemory(&d3dpp, sizeof(d3dpp); 36 d3dpp.Windowed = TRUE; 37 d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD; 38 d3dpp.BackBufferFormat = D3DFMT_UNKNOWN; 39 if(FAILED( g_pD3D-CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, 40 hWnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING, 41 &d3dpp, &g_pd3dDevice) 42 43 return E_FAIL; 44 45 g_pd3dDevice-SetRenderState(D3DRS_CULLMODE, D3DCULL_NONE); 46 / Turn off D3D lighting, since we are providing our own vertex colors 47 g_pd3dDevice-SetRenderState( D3DRS_LIGHTING, FALSE ); 48 if (FAILED(InitObject() 49 return E_FAIL; 50 return S_OK; 51 52 void SetupMatrices() 53 54 D3DXMATRIX matWorld; 55 UINT iTime = timeGetTime() % 1000; 56 FLOAT fAngle = iTime * ( 2.0f * D3DX_PI ) / 1000.0f; 57 D3DXMatrixRotationY(&matWorld, fAngle); 58 g_pd3dDevice-SetTransform(D3DTS_WORLD, &matWorld); 59 D3DXVECTOR3 vEyePt(0.0f, 3.0f, -5.0f); 60 D3DXVECTOR3 vLookAtPt(0.0f, 0.0f, 0.0f); 61 D3DXVECTOR3 vUp(0.0f, 1.0f, 0.0f); 62 D3DXMATRIXA16 matView; 63 D3DXMatrixLookAtLH(&matView, &vEyePt, &vLookAtPt, &vUp); 64 g_pd3dDevice-SetTransform(D3DTS_VIEW, &matView); 65 D3DXMATRIX matPoj; 66 D3DXMatrixPerspectiveFovLH(&matPoj, D3DX_PI/4, 1.0f, 1.0f, 100.0f); 67 g_pd3dDevice-SetTransform(D3DTS_PROJECTION, &matPoj); 68 69 void Render() 70 71 g_pd3dDevice-Clear(0,NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0, 0, 255), 1.0f, 0); 72 g_pd3dDevice-BeginScene(); 73 SetupMatrices(); 74 g_pd3dDevice-SetStreamSource(0, g_pVB, 0, sizeof(CUSTOMVERTEX); 75 g_pd3dDevice-SetFVF(D3DFVF_CUSTOMVERTEX); 76 g_pd3dDevice-DrawPrimitive(D3DPT_TRIANGLELIST, 0, 1); 77 g_pd3dDevice-EndScene(); 78 g_pd3dDevice-Present(NULL, NULL, NULL, NULL); 79 80 void Cleanup() 81 82 if (g_pd3dDevice) 83 g_pd3dDevice-Release(); 84 if (g_pD3D) 85 g_pD3D-Release(); 86 if (g_pVB) 87 g_pVB-Release(); 88 89 LRESULT WINAPI MsgProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam) 90 91 switch (msg) 92 93 case WM_DESTROY: 94 PostQuitMessage(0); 95 return 0; 96 case WM_PAINT: 97 ValidateRect(hWnd, NULL); 98 return 0; 99 100 return DefWindowProc(hWnd, msg, wParam, lParam);101 102 INT WINAPI WinMain(_in HINSTANCE hInstance, _in_opt HINSTANCE hPrevInstance, _in_opt LPSTR lpCmdLine, _in int nShowCmd )103 104 WNDCLASSEX wc = sizeof(WNDCLASSEX), CS_CLASSDC, MsgProc, 0, 0, GetModuleHandle(NULL), NULL, NULL, NULL, NULL, LDirect3D, NULL; 105 RegisterClassEx(&wc); 106 / Create the application window 107 HWND hWnd = CreateWindow(LDirect3D, 108 LLearn, WS_OVERLAPPEDWINDOW, 109 100, 100, 300, 300, 110 GetDesktopWindow(), 111 NULL, wc.hInstance, NULL); 112 /113 ShowWindow(hWnd, SW_SHOW); 114 if (SUCCEEDED(InitD3D(hWnd) 115 116 ShowWindow(hWnd, SW_SHOWDEFAULT); 117 UpdateWindow(hWnd); 118 MSG msg; 119 ZeroMemory(&msg, sizeof(msg); 120 while (msg.message != WM_QUIT) 121 122 if(PeekMessage(&msg, NULL, 0, 0, PM_REMOVE) 123 124 TranslateMessage(&msg); 125 DispatchMessage(&msg); 126 127 else 128 Render(); 129 130 131 UnregisterClass( LDirect3D, wc.hInstance ); 13
