hello everyone?i trouble with a question like the picture?
the right is render correct ? the left is not render correct?
can anyone konw what's wrong?
the code?
3DPRESENT_PARAMETERS d3dpp;
ZeroMemory( &d3dpp, sizeof(d3dpp) );
d3dpp.Windowed = TRUE;
d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD;
D3DDISPLAYMODE mode; if(FAILED(g_pD3D->GetAdapterDisplayMode(D3DADAPTER_DEFAULT , &mode))) {
return 0;
}
d3dpp.BackBufferFormat = mode.Format;
d3dpp.hDeviceWindow = (HWND)m_hWnd; d3dpp.EnableAutoDepthStencil = TRUE;
d3dpp.AutoDepthStencilFormat = D3DFMT_D16;
if(g_pD3D->CheckDeviceMultiSampleType(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL,
mode.Format,FALSE,D3DMULTISAMPLE_4_SAMPLES, NULL) == D3D_OK)
{
d3dpp.MultiSampleType = D3DMULTISAMPLE_4_SAMPLES;
}
else
{
d3dpp.MultiSampleType = D3DMULTISAMPLE_NONE;
}
d3dpp.PresentationInterval = D3DPRESENT_INTERVAL_DEFAULT;
}
if(FAILED(s_pD3DDevice->CreateAdditionalSwapChain(&d3dpp, &m_pSwapChain)))
{
return 0;
}
if i use d3dpp.MultiSampleType = D3DMULTISAMPLE_4_SAMPLES; the picture render well be the left.
if i use d3dpp.MultiSampleType = D3DMULTISAMPLE_NONE; the picture render well be the right.
the render code:
IDirect3DSurface9 * pBackBuffer = NULL;
if (NULL != m_pSwapChain)
{
m_pSwapChain->GetBackBuffer(0,D3DBACKBUFFER_TYPE_MONO,&pBackBuffer);
}
m_pD3DDevice->SetRenderTarget(0 , pBackBuffer);
m_pD3DDevice->StretchRect(m_pSurface,pRectSrc,m_pBackSurface,NULL,D3DTEXF_LINEAR);
hr = m_pSwapChain->Present(NULL, NULL, (HWND)hWnd, NULL,0 );
if (FAILED(hr))
{
return 0;
}
