D3D初始化方法

1.加载库

#pragma comment(lib,"d3d9.lib") #pragma comment(lib,"d3dx9.lib") #pragma comment(lib,"winmm.lib") #include <d3d9.h>#include <d3dx9math.h>

2.定义一个派生于generic CWnd的类CD3DWnd

3. 在CD3DWnd类中定义

 

LPDIRECT3D9 m_pD3D; //Direct3D对象的接口指针LPDIRECT3DDEVICE9 m_pD3DDevice; //设备对象的接口指针

4. 在OnCreate()出调用InitD3D()函数

void CD3DWnd::InitD3D(){ // 创建D3D对象，并获得接口ID3D9的指针// 我们将通过该指针操作D3D对象 m_pD3D = ::Direct3DCreate9(D3D_SDK_VERSION); D3DPRESENT_PARAMETERS d3dpp; ZeroMemory( &d3dpp, sizeof(d3dpp)); d3dpp.Windowed = TRUE; // 创建窗口模式的D3D程序 d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD; d3dpp.BackBufferFormat = D3DFMT_UNKNOWN; // 调用方法IDirect3d9::CreateDevice创建设备对象，并获取 // 接口ID3DDevice9指针，我们将通过该指针操作设备对象 m_pD3D->CreateDevice( D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, m_hWnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING, &d3dpp, &m_pD3DDevice );m_pD3DDevice->SetRenderState(D3DRS_CULLMODE,D3DCULL_NONE);}

  

5. 在OnPaint()调用Render()

void CD3DWnd::Render(){ if( NULL == m_pD3DDevice ) return; // Clear the backbuffer to a blue color m_pD3DDevice->Clear( 0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0,0,255), 1.0f, 0); // Begin the scene if( SUCCEEDED( m_pD3DDevice->BeginScene() ) ) { // Rendering of scene objects can happen hereSetupMatrices(); // 设置变换矩阵m_pD3DDevice->SetFVF(D3DFVF_CUSTOMVERTEX);m_pD3DDevice->SetStreamSource(0,m_pVB,0,sizeof(CUSTOMVERTEX));m_pD3DDevice->DrawPrimitive(D3DPT_TRIANGLELIST,0,1); // End the scene m_pD3DDevice->EndScene(); } // Present the backbuffer contents to the display m_pD3DDevice->Present( NULL, NULL, NULL, NULL );}

 

 

6.   在OnDestroy()调用Cleanup()

void CD3DWnd::Cleanup(){m_pVB->Release();m_pD3DDevice->Release();m_pD3D->Release();}
