Using WPF and SlimDx (DirectX 10/11)
- by slurmomatic
I am using SlimDX with WinForms for a while now, but want to make the switch to WPF now. However, I can't figure out how to get DX10/11 working with WPF. The February release of SlimDX provides a WPF example, which only works with DX 9 though.
I found the following solution: http://jmorrill.hjtcentral.com/Home/tabid/428/EntryId/437/Direct3D-10-11-Direct2D-in-WPF.aspx
but can't get it to work with SlimDX. My main problem is the shared resource handle as I don't know how to retrieve the shared handle from a SlimDX texture. I can't find any information to this topic.
In C++ the code looks like this:
HRESULT D3DImageEx::GetSharedHandle(IUnknown *pUnknown, HANDLE * pHandle)
{
HRESULT hr = S_OK;
*pHandle = NULL;
IDXGIResource* pSurface;
if (FAILED(hr = pUnknown->QueryInterface(__uuidof(IDXGIResource), (void**)&pSurface)))
return hr;
hr = pSurface->GetSharedHandle(pHandle);
pSurface->Release();
return hr;
}
Basically, what I want to do (because I think that this is the solution), is to share a texture between a Direct3d9DeviceEx (for rendering the WPF D3DImage) and a Direct3d10Device (a texture render target for my scene).
Any pointers in the right direction are greatly appreciated.
