MultiHook

Universal graphical hook for Windows apps, although it should work on Linux too if you implement it correctly, that will display an ImGui Demo Window as an example.

How it works

DirectX

We create a 'dummy device' and a 'dummy swapchain' (for DirectX10 and higher). See the CreateDeviceD3DX function in every DirectX backend. See DX12 example 'CreateDeviceD3D12'. The point is to get a pointer to the vTable to get the required functions addresses. We release it right after getting the pointers because we won't use our 'dummy device' and 'dummy swapchain' for drawing. See code used in DX12 backend hook.

OpenGL

We hook wglSwapBuffers which is an exported function in opengl32.dll. See code used in OpenGL backend hook.

Vulkan

We create a 'dummy device' to get the required functions addresses. The point is to hook into vkQueuePresentKHR where we will submit the queue with our data from our command pool and our command buffer. See code used in Vulkan backend hook.
