[Discuss] Direct3D Gdi func

What does Direct3D use or how does it paint onto a game window because its pretty smooth and Its not using BitBlt or StretchBlt to double buffer.

Edit: I tried detouring them and I also detoured Dispatch message, but it only gets WM_PAINT when its painting back invalidated areas.

GDI uses CPU. Direct3D can do Software Rendering and Hardware however. DirectDraw... well she is a whole notha woman

You may find some answers by checkout the GetDC() function. Surfaces and some texture you can get the device context and then use GDI functions.

I think that yea it doesnt use any of the regular GDI api's to paint but it is similar to bitblt.
In DirectDraw.

It's probably a lame way, but you can draw on DirectDraw games like this:

    HWND window = NULL;
    while(window == NULL)
    {
                  Sleep(100);
                  window = FindWindow("whatever", "whatever");
    }
    COLORREF color = RGB(255,0,0);
    HDC hdc = GetDC(window);
    SetPixel(hdc, 105,105,red);
    ReleaseDC(window, hdc);

I only tryed it on old games but there it worked even in fullscreen.

>_> the point is to do it efficiently, as in detouring the drawing function and overlaying there instead of slow flickering queue stuffing.

Does anyone know any game recorders that detour the first 5 bytes of endscene and record from that?

it hooks present......and its a recorder.

why the fuck would you need help detouring or need an endscene only recorder 0_o .Most hook present , swap present , internal . I think cuz thats the time that the backbuffer is flipped to the front(maybe record the back right before its flipped???? IDK and swap chain has all the useful func for this). I didnt look thru the src i just knew it was opensourced recorder.

also why give me negative rep? I gave you opensourced link and I explained the reasoning to it so ..............................................

Because u used sum foul language when it was not needed.
