Vista - wpf inside d3d

hi,
at my development team we are also trying to get wpf to render on a
d3d surface...if we don't find a way we simply can't use it...that
would be a real pitty!

what we curently are trying to do, is to open a wpf form in background
(behind our fullscreen d3d device), grab the frames rendered to the
desktop (via screenshot methods and/or print methods) and copy them
into texture buffer!

lets see if it works...but we would prefer a cleaner solution provided
by the wpf api itself!

greets

Matthias

ps: another idea was to steal the surface from the wpf device at low
level on driver/gpu basis...that would be a real hack!

anyone!?

The best you can do is render the WPF content to a RenderTargetBitmap, which
derives from BitmapSource, and use CopyPixels to read the result. Note that
everything in the RTB will be rendered in software and you'll be doing a
software copy, of course. There is no way for you to go from a hardware WPF
surface -> hardware D3D surface.
