GH D3D11 Hook
Barebones D3D11 hook.
x86/x64 Compatible
This is about the simplest example I could create for hooking DirectX 11. The code is heavily commented and doesn't rely on any external libraries. As long as you have a recent version of the Windows SDK then this code should run.
The example is a DLL that you inject into a game using DirectX 11 and it should render a triangle in the top left corner of the screen.
The code creates a dummy device and swapchain to get the address of Present out of the dummy swapchain's virtual method table. Then we create a simple trampoline hook to detour Present and render our triangle.
While the code isn't extremely elegant, it's not meant to be. This is just a simple PoC to demonstrate one way, a fairly decent way imo, of hooking direct3d 11 and rendering our own simple geometry.
