I would like to flip the whole fullscreen directX output horizontally so that the final output is presented mirror inverted.
Is there a way to create a
IDirect3DDevice9 instance which produces mirrored output? Or even better: is there a way I can mirror the output just before the final call to the
Present(...) method of the
The underlying objective is to be able to use a projector which needs vertically flipped input.
The software I am currently using allows to register callbacks and hands over a handle to the
After my method is called and returns, the directx output is presented. This repeats after each frame.
I would like to flip the presented output horizontally.
I tried the following:
- Use settings of the projector to flip the image (not supported)
- Find a setting in the Operating System (windows7 doesn't support flipping of the image)
- Find a setting in the graphics driver (AMD Catalyst) but only rotation is supported, not horizontal flipping
I have only little experience with directx so please bear with me (this is also why I would appreciate sample code or at least pointers to the right direction).
I found out that I should be able to call
SetTransform on the
Direct3DDevice9 handle to change the
D3DTS_PROJECTION with a proper Matrix. However this does not work in my example application.
