飞飞多采样抗锯齿设置
老外论坛的，不知道效果如何，我的电脑也看不出有啥变化- ------------------------
d3dapp.cpp
-----------------------
找到：
#ifdef __XUZHU
#if 0
// Create the device
hr = m_pD3D->CreateDevice( m_pD3D->GetAdapterCount()-1, D3DDEVTYPE_REF,
m_hWndFocus, behaviorFlags, &m_d3dpp,
&m_pd3dDevice );
在第二个#else 下面的代码
hr = m_pD3D->CreateDevice( m_d3dSettings.AdapterOrdinal(), pDeviceInfo->DevType, m_hWndFocus, behaviorFlags, &m_d3dpp, &m_pd3dDevice );
替换为：
DWORD MSQuality = 0;
D3DMULTISAMPLE_TYPE MSType = D3DMULTISAMPLE_NONE;
if( SUCCEEDED( m_pD3D->CheckDeviceMultiSampleType(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, D3DFMT_A8R8G8B8, TRUE, D3DMULTISAMPLE_8_SAMPLES, &MSQuality) ))
MSType = D3DMULTISAMPLE_8_SAMPLES;
else if( SUCCEEDED( m_pD3D->CheckDeviceMultiSampleType(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, D3DFMT_A8R8G8B8, TRUE, D3DMULTISAMPLE_4_SAMPLES, &MSQuality) ))
MSType = D3DMULTISAMPLE_4_SAMPLES;
else if( SUCCEEDED( m_pD3D->CheckDeviceMultiSampleType(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, D3DFMT_A8R8G8B8, TRUE, D3DMULTISAMPLE_2_SAMPLES, &MSQuality) ))
MSType = D3DMULTISAMPLE_2_SAMPLES;
int MSQ = MSQuality - 1;
// --------------------------------------------------------------
// ... Below Will Display a message box on Start-Up with the AntiAliasing
// ... Multisample level Your Graphics card can handle .
// ---------------------------------------------------------------
// char msaaText;
// sprintf( msaaText, "Multi Sample Type = x%d", MSType );
// MessageBox( NULL, msaaText, "MSAA AMOUNT", MB_OK );
// -------------------------------------------------------------------
m_d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD;
m_d3dpp.MultiSampleType = MSType;
m_d3dpp.MultiSampleQuality = MSQ;
m_d3dpp.BackBufferFormat = D3DFMT_X8R8G8B8;
m_d3dpp.EnableAutoDepthStencil = TRUE;
m_d3dpp.AutoDepthStencilFormat = D3DFMT_D16;
m_d3dpp.Flags = 0;
m_d3dpp.FullScreen_RefreshRateInHz = D3DPRESENT_RATE_DEFAULT;
m_d3dpp.PresentationInterval = D3DPRESENT_INTERVAL_DEFAULT;
hr = m_pD3D->CreateDevice( m_d3dSettings.AdapterOrdinal(), pDeviceInfo->DevType,
m_hWndFocus, behaviorFlags, &m_d3dpp,
&m_pd3dDevice );
m_pd3dDevice->SetRenderState(D3DRS_MULTISAMPLEANTIALIAS, TRUE);
m_pd3dDevice->SetRenderState(D3DRS_ALPHABLENDENABLE, TRUE);
m_pd3dDevice->SetRenderState(D3DRS_ALPHAFUNC, D3DCMP_GREATEREQUAL);
m_pd3dDevice->SetRenderState(D3DRS_ALPHAREF, (DWORD)8);
m_pd3dDevice->SetRenderState(D3DRS_ALPHATESTENABLE, TRUE);
完了！
