Ogre/WPF Integration using D3DImage

[jpho]

D3DImage is an interoperability technology in Windows Presentation Foundation that allows efficient interop between WPF and Direct3D. There's code and explanations about how to set it up on MSDN: http://msdn.microsoft.com/en-us/library/cc656710.aspx. It's very low-level D3D-specific stuff. I got it to run for simple D3D-proof of concept (not so hard, as all the code is on MSDN).

But for integrating Ogre, more would have to be done. If I understand it correctly (which is not a given ), the following problems exist:

- Initialization of the direct3d plugin would have to be adapted: So far, I think it's only possible to pass a HWND ptr to a win32 window, not to use existing D3D context.
- Direct3D9 plugin would have to allow using *3D9Ex for context creation, required for hardware-accelerated blitting of the D3D surface.

I have to admit I'm a bit lost, as I'm new to Windows development and Direct3D, and especially the MSDN-example was quite confusing for someone used to OpenGL. This also applies to the D3D9Plugin device/driver/... initialization in Ogre.

If someone here could give me a few pointers on how to best achieve D3DImage-based WPF integration of Ogre, I would be very grateful; especially, what path the new Parameters would have to take through Ogre to allow shared use of the D3D9Surface.
