MFC+D3D

1. 新建单文档类型的MFC应用程序

2. 添加三个lib文件：d3d9.lib d3dx9.lib winmm.lib

3. 在D3D9MFCView.h文件中添加如下代码：

包含头文件：#include <d3dx9.h> //88888

添加成员函数和成员变量：

 

//88888private:HRESULT initD3D(HWND hwnd,int width,int height,bool windowed,D3DDEVTYPE deviceType);HRESULT setup(int width, int height);HRESULT cleanup();public:HRESULT update(float timeDelta);HRESULT render();private:IDirect3DDevice9* _device;D3DPRESENT_PARAMETERS _d3dpp;ID3DXMesh* _teapot;public:virtual void OnInitialUpdate();afx_msg void OnSize(UINT nType, int cx, int cy);afx_msg BOOL OnEraseBkgnd(CDC* pDC);//88888

 

 

对应函数实现：

CD3D9MFCView::CD3D9MFCView():_device(0),_teapot(0){// TODO: add construction code here::ZeroMemory(&_d3dpp,sizeof(_d3dpp));//88888}CD3D9MFCView::~CD3D9MFCView(){if (_teapot)_teapot->Release();if(_device)_device->Release();}HRESULT CD3D9MFCView::initD3D(HWND hwnd, int width, int height, bool windowed, D3DDEVTYPE deviceType){HRESULT hr = 0;// Step 1: Create the IDirect3D9 object.IDirect3D9* d3d9 = 0;d3d9 = Direct3DCreate9(D3D_SDK_VERSION);if( !d3d9 ){::MessageBox(0, "Direct3DCreate9() - FAILED", 0, 0);return E_FAIL;}// Step 2: Check for hardware vp.D3DCAPS9 caps;d3d9->GetDeviceCaps(D3DADAPTER_DEFAULT, deviceType, &caps);int vp = 0;if( caps.DevCaps & D3DDEVCAPS_HWTRANSFORMANDLIGHT )vp = D3DCREATE_HARDWARE_VERTEXPROCESSING;elsevp = D3DCREATE_SOFTWARE_VERTEXPROCESSING;// Step 3: Fill out the D3DPRESENT_PARAMETERS structure._d3dpp.BackBufferWidth = width;_d3dpp.BackBufferHeight = height;_d3dpp.BackBufferFormat = D3DFMT_A8R8G8B8;_d3dpp.BackBufferCount = 1;_d3dpp.MultiSampleType = D3DMULTISAMPLE_NONE;_d3dpp.MultiSampleQuality = 0;_d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD;_d3dpp.hDeviceWindow = hwnd;_d3dpp.Windowed = windowed;_d3dpp.EnableAutoDepthStencil = true;_d3dpp.AutoDepthStencilFormat = D3DFMT_D24S8;_d3dpp.Flags = 0;_d3dpp.FullScreen_RefreshRateInHz = D3DPRESENT_RATE_DEFAULT;_d3dpp.PresentationInterval =D3DPRESENT_INTERVAL_IMMEDIATE;// Step 4: Create the device.hr = d3d9->CreateDevice(D3DADAPTER_DEFAULT, // primary adapterdeviceType, // device typehwnd, // window associated with devicevp, // vertex processing&_d3dpp, // present parameters&_device);

// done with d3d9 object::MessageBox(0, "CreateDevice() - FAILED", 0, 0);return hr;}}d3d9->Release(); // done with d3d9 objectreturn S_OK;}HRESULT CD3D9MFCView::setup(int width, int height){if( _device ){// Set view matrix.D3DXMATRIX V;D3DXVECTOR3 pos (0.0f, 0.0f, -6.0f);D3DXVECTOR3 target (0.0f, 0.0f, 0.0f);D3DXVECTOR3 up (0.0f, 1.0f, 0.0f);D3DXMatrixLookAtLH(&V, &pos, &target, &up);_device->SetTransform(D3DTS_VIEW, &V);// Create the teapot.if( !_teapot)D3DXCreateTeapot(_device, &_teapot, 0);// Use wireframe mode and turn off lighting._device->SetRenderState(D3DRS_FILLMODE, D3DFILL_WIREFRAME);_device->SetRenderState(D3DRS_LIGHTING, false);// Size the viewport based on window dimensions.D3DVIEWPORT9 vp = {0, 0, width, height, 0.0f, 1.0f};_device->SetViewport( &vp );// Set the projection matrix based on the// window dimensions.D3DXMATRIX P;D3DXMatrixPerspectiveFovLH(&P,D3DX_PI * 0.25f,//45-degree field of view(float)width / (float)height,1.0f,1000.0f);_device->SetTransform(D3DTS_PROJECTION, &P);}return S_OK;}HRESULT CD3D9MFCView::cleanup(){// Nothing to Destroy.return S_OK;}HRESULT CD3D9MFCView::update(float timeDelta){if( _device ){//// Spin the teapot around the y-axis.//static float angle = 0.0f;D3DXMATRIX yRotationMatrix;D3DXMatrixRotationY(&yRotationMatrix, angle);_device->SetTransform(D3DTS_WORLD, &yRotationMatrix);angle += timeDelta;if(angle >= D3DX_PI * 2.0f)angle = 0.0f;}return S_OK;}HRESULT CD3D9MFCView::render(){if( _device ){//// Draw the scene.//_device->Clear(0, 0,D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER,0x00000000, 1.0f, 0);_device->BeginScene();// Draw the teapot._teapot->DrawSubset(0);_device->EndScene();_device->Present(0, 0, 0, 0);}return S_OK;}void CD3D9MFCView::OnInitialUpdate(){CView::OnInitialUpdate();// TODO: Add your specialized code here and/or call the base classCRect rect;GetClientRect(&rect);// Initialize Direct3D (e.g. acquire a IDirect3DDevice9 poniter).HRESULT hr = initD3D(GetSafeHwnd(),rect.right,rect.bottom,true,D3DDEVTYPE_HAL);if(FAILED(hr)){MessageBox("initD3D() - Failed", "Error");::PostQuitMessage(0);}// Setup the application.hr = setup(rect.right, rect.bottom);if(FAILED(hr)){MessageBox("setup() - Failed", "Error");::PostQuitMessage(0);}}void CD3D9MFCView::OnSize(UINT nType, int cx, int cy){CView::OnSize(nType, cx, cy);// TODO: Add your message handler code hereif( _device ){HRESULT hr = 0;// On a resize we must change the dimensions of the// back buffers to match the new window size._d3dpp.BackBufferWidth = cx;_d3dpp.BackBufferHeight = cy;// We are about to call Reset, free any resources// that need to be freed prior to a Reset.hr = cleanup();if(FAILED(hr)){MessageBox("destroy() - Failed", "Error");::PostQuitMessage(0);}// Reset the flipping chain with the new window dimensions.// Note that all device states are reset to the default// after this call.hr = _device->Reset(&_d3dpp);if(FAILED(hr)){MessageBox("Reset() - Failed", "Error");::PostQuitMessage(0);}// Reinitialize resource and device states since we// Reset everything.hr = setup(cx, cy);if(FAILED(hr)){MessageBox("setup() - Failed", "Error");::PostQuitMessage(0);}}}BOOL CD3D9MFCView::OnEraseBkgnd(CDC* pDC){// TODO: Add your message handler code here and/or call defaultreturn FALSE;//return CView::OnEraseBkgnd(pDC);}

 

 

3. 在类CD3D9MFCApp中添加如下代码。

包含头文件：#include "mmsystem.h"//88888

添加重载函数：

BOOL CD3D9MFCApp::OnIdle(LONG lCount){// TODO: Add your specialized code here and/or call the base classCWinApp::OnIdle(lCount);CWnd* mainFrame = AfxGetMainWnd();CD3D9MFCView* cview =(CD3D9MFCView*)mainFrame->GetWindow(GW_CHILD);// Save last time.static float lastTime = (float)timeGetTime();// Compute time now.float currentTime = (float)timeGetTime();// Compute the difference: time elapsed in seconds.float deltaTime = (currentTime - lastTime) * 0.001f;// Last time is now current time.lastTime = currentTime;cview->update(deltaTime);cview->render();return TRUE;//return CWinApp::OnIdle(lCount);}

 

 

效果如下：
