最简单的DX窗口程序

旧城等待， 2023-06-05 11:18 6阅读 0赞

一、下载DX装起来：[http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=6812][http_www.microsoft.com_download_en_details.aspx_displaylang_en_id_6812]

二、创建一个Win32窗口程序，空的，创建一个cpp文件，把项目属性配置一下，主要就是连接的静态库设置一下，要连接的静态库如下  
d3d9.lib  
d3dcompiler.lib --HLSL编译器  
DxErr.lib --错误库  
dxguid.lib --定义了Direct3D中所需要的GUID，即COM需要引用的  
其它的，像DX的动态库、运行库、运行目录，在安装DX SDK的时候就已经设置好了，可以在选项里面看到

三、把下面的代码贴上去，编译运行，OK

#include <Windows.h>
    #include <d3d9.h>
    #include <d3dx9.h>
    
    IDirect3D9 *g_pD3D;  // D3D对象
    IDirect3DDevice9 *g_pd3dDevice;   // D3D设备
    
    LRESULT WINAPI MsgProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam);
    void Render();
    void Cleanup();
    
    INT WINAPI WinMain( __in HINSTANCE hInstance, __in_opt HINSTANCE hPrevInstance, __in_opt LPSTR lpCmdLine, __in int nShowCmd )
    {
           // step 1.
           WNDCLASSEX wc = {
                  sizeof(WNDCLASSEX),
                  CS_CLASSDC,
                  MsgProc,
                  0L, 0L,
                  GetModuleHandle(NULL),
                  NULL, NULL, NULL, NULL,
                  "Direct3D Frame", NULL };
    
                  RegisterClassEx(&wc);
    
                  HWND hWnd = CreateWindow(
                         "Direct3D Frame",
                         "Direct3D BaseFrame",
                         WS_OVERLAPPEDWINDOW, 100, 100, 300, 300,
                         GetDesktopWindow(), NULL, wc.hInstance, NULL);
    
                  ShowWindow(hWnd, nShowCmd);
    
                  // step 2.
                  if (NULL == (g_pD3D = Direct3DCreate9(D3D_SDK_VERSION)))
                  {
                         return E_FAIL;
                  }
    
                  D3DPRESENT_PARAMETERS d3dpp;
                  ZeroMemory(&d3dpp, sizeof(d3dpp));
                  d3dpp.Windowed = TRUE;
                  d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD;
                  d3dpp.BackBufferFormat = D3DFMT_UNKNOWN;
    
                  if (FAILED(g_pD3D->CreateDevice(
                         D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, hWnd,
                         D3DCREATE_SOFTWARE_VERTEXPROCESSING,
                         &d3dpp, &g_pd3dDevice)));
    
                  // step 3.
                  MSG msg;
                  while (GetMessage(&msg, NULL, 0, 0))
                  {
                         TranslateMessage(&msg);
                         DispatchMessage(&msg);
                  }
    }
    
    LRESULT WINAPI MsgProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam)
    {
           switch (msg)
           {
           case WM_DESTROY:
                  Cleanup();
                  PostQuitMessage(0);
                  return 0;
    
           case WM_PAINT:
                  Render();
                  ValidateRect(hWnd, NULL);
                  return 0;
           }
    
           return DefWindowProc(hWnd, msg, wParam, lParam);
    }
    
    void Render()
    {
           g_pd3dDevice->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0,0,255), 1.0f, 0);
    
           g_pd3dDevice->BeginScene();
           // rendering of scene objects happens here
           g_pd3dDevice->EndScene();
    
           g_pd3dDevice->Present(NULL, NULL, NULL, NULL);
    }
    
    void Cleanup()
    {
           if (g_pd3dDevice != NULL)
                  g_pd3dDevice ->Release();
           if (g_pD3D != NULL)
                  g_pD3D->Release();
    }

熟悉Win32程序开发的一看就知道，在响应WM\_PAINT消息的时候换成了调用Render()这个函数，在这个函数里面你就可以用DX"画"自己的东东了<^^>
