Failing to get D2D into my DX11 Engine

indiehjaerta · 2011-12-07T21:17:40

So I have a working DX11 Engine right now for rendering models and I felt I should add Texts right now and learned that Direct2D was the way. However I don't understand how to do it. Class Declaration of the DX11 Engine is: ID3D11Device* m_pDevice; ID3D11DeviceContext* m_pDeviceContext; IDXGISwapChain* m_pSwapChain; And the Engine Render Function is as follows: m_D2DEngine is what I wanted to take care of the Rendering of a queue of texts. void DX11Engine::Render() { m_pDeviceContext->ClearRenderTargetView(m_pBackbuffer, D3DXCOLOR(0.0f, 0.2f, 0.4f, 1.0f)); m_pDeviceContext->ClearDepthStencilView(m_pDepthStencilView, D3D11_CLEAR_DEPTH, 1.0f, 0); m_pScene->Render(); m_D2DEngine.Render(); m_pSwapChain->Present(0, 0); } ] Render Function in the D2DEngine looks as follows: ID3D10Device* m_pDevice; D2D Needed a D3D10Device void Direct2DEngine::Render() { HRESULT hr = S_OK; m_pBackBuffer->BeginDraw(); m_pBackBuffer->SetTransform(D2D1::Matrix3x2F::Identity()); D2D1_SIZE_F rtSize = m_pBackBuffer->GetSize(); ID2D1SolidColorBrush* pBackBufferTextBrush = NULL; hr = m_pBackBuffer->CreateSolidColorBrush( D2D1::ColorF(D2D1::ColorF::Red), &pBackBufferTextBrush ); for (unsigned int index = 0; index < m_vecTextToRender.size(); index++) { m_pBackBuffer->DrawText( StringToWideString(m_vecTextToRender[index].m_strText).c_str(), m_vecTextToRender[index].m_strText.size(), m_pTextFormat, D2D1::RectF(0.0f, 0.0f, rtSize.width, rtSize.height), pBackBufferTextBrush ); } hr = m_pBackBuffer->EndDraw(); if (SUCCEEDED(hr) && m_pRenderTarget) { // Swap chain will tell us how big the back buffer is DXGI_SWAP_CHAIN_DESC swapDesc; hr = m_pSwapChain->GetDesc(&swapDesc); if (SUCCEEDED(hr)) { m_pDevice->ClearDepthStencilView( m_pDepthStencilView, D3D10_CLEAR_DEPTH, 1, 0 ); if (SUCCEEDED(hr)) { m_pDiffuseVariableNoRef->SetResource(NULL); m_pTechniqueNoRef->GetPassByIndex(0)->Apply(0); // Draw the D2D content into a D3D surface. hr = RenderD2DContentIntoSurface(); } if (SUCCEEDED(hr)) { m_pDiffuseVariableNoRef->SetResource(m_pTextureResourceView); // Update variables that change once per frame. m_pWorldVariableNoRef->SetMatrix((float*)&m_WorldMatrix); // Set the index buffer. m_pDevice->IASetIndexBuffer(m_pFacesIndexBuffer, DXGI_FORMAT_R16_UINT, 0); // Render the scene m_pTechniqueNoRef->GetPassByIndex(0)->Apply(0); m_pDevice->DrawIndexed( ARRAYSIZE(s_FacesIndexArray), 0, 0 ); // Draw some text using a red brush on top of everything //if (m_pBackBuffer) //{ //m_pBackBuffer->BeginDraw(); //m_pBackBuffer->SetTransform(D2D1::Matrix3x2F::Identity()); // Text format object will center the text in layout //D2D1_SIZE_F rtSize = m_pBackBuffer->GetSize(); //ID2D1SolidColorBrush* pBackBufferTextBrush = NULL; //hr = m_pBackBuffer->CreateSolidColorBrush( // D2D1::ColorF(D2D1::ColorF::Red), // &pBackBufferTextBrush // ); //for (unsigned int index = 0; index < m_vecTextToRender.size(); index++) //{ // m_pBackBuffer->DrawText( // StringToWideString(m_vecTextToRender[index].m_strText).c_str(), // m_vecTextToRender[index].m_strText.size(), // m_pTextFormat, // D2D1::RectF(0.0f, 0.0f, rtSize.width, rtSize.height), // pBackBufferTextBrush // ); //} //hr = m_pBackBuffer->EndDraw(); //} if (SUCCEEDED(hr)) { hr = m_pSwapChain->Present(1, 0); } } } } m_vecTextToRender.clear(); } So my problem here is that it flicker betweens the rendered 1st: DX11 Picture - Blue background atm 2nd: D2DText - Black backround - Red Text So how should I change the D2D Render function to draw it to my normal Picture? I'm so unclear with everything since I had to create the D3D10Device also.

Ok, still no text showing and all HR reults give S_OK;
Tried running PIX to see if that could help me somehow but running it through PIX gave me this message:

Frame 000001 ........PRE: <this=0x06a39650>ID3D10Device::OpenSharedResource(<unknown type 157>, IID_IDXGISurface1, 0x0035F45C)
Frame 000001 ........POST: <S_OK><this=0x06a39650> ID3D10Device::OpenSharedResource(<unknown type 157>, IID_IDXGISurface1, 0x0035F45C)
Frame 000001 ........PRE: D3D10CreateStateBlock(0x00EDDB38, 0x0035EDC4, 0x00799E20)
An unhandled exception occurred.

And it crashes through PIX, not when I run straight from the folder.

It should be around these lines in init:



	// Open the surface for the shared texture in D3D10.1

	IDXGISurface1* pSharedSurface10;	



	hr = m_pD3D101Device->OpenSharedResource(sharedHandle10, __uuidof(IDXGISurface1), (void**)(&pSharedSurface10));



	hr = pSharedSurface10->QueryInterface(__uuidof(IDXGIKeyedMutex), (void**)&m_pKeyedMutex10);

Hey, post all the code that initializes D3D11, D3D10, D2D, and DirectWrite. I know it's a problem there. I just helped someone with this problem too, and it was such an easily overlooked problem. It had to do with creating his depth/stencil and render target view textures. Check to make sure that your depth/stencil and render target view textures are same dimensions, same miltisample count, same multisample quality, and same resource types.

Also just to point out that the primitive topology in the render function above is being set as a point list instead of a triangle list.

HAHA! I just realized it was you that I had just helped!

Did you get rid of this problem? I'm able to render text just fine, but when I run my application through PIX, I get the exact same problem as above. Do I have to choose between running PIX or render text? That's a bit lame
