2 years ago It would be a fair bit of work, but probably doable within 2 days by someone experienced.
The starting point would be the following:
- Clone https://github.com/Sewer56/DearImguiSharp
- Build Dear ImGui C Bindings (
~~(Note: Use MinGW and GCC to generate the bindings, cl/VS Compiler doesn't always work) ~~
cimgui) with DX12 support. (edit generator.sh to include dx12)(The library currently used was built with ./generator.lua gcc "internal" win32 dx9 dx11 in the script.)
- Build
DearImGuiSharp (see readme).- Add and implement Reloaded.Imgui.Hook.Direct3D12 to this project.
[Update September 2022. The base library now supports the remaining backends, including DX12 & Vulkan]
=======
As for how to implement Reloaded.Imgui.Hook.Direct3D12?
I'd check two things:
- Official Dear ImGui D3D12 Example & D3D12 Backend: https://github.com/ocornut/imgui/blob/master/examples/example_win32_directx12/main.cpp https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_dx12.cpp
(To see what might be necessary to hook, specifically look for ImGui backend function calls.)
- Existing Implementations Of course you're gonna only run into C++ implementations, but some of them don't look too difficult to bring over; like this one from a Game Hacking forum: https://www.unknowncheats.me/forum/d3d-tutorials-and-source/457178-imgui-hook-directx12-directx11-directx9-x64-x86.html
The source code there looks fairly reasonable. Personally I was able to implement DX11 support without ever having used it before; so it's definitively possible.

Unrelated: You can use Reloaded II for running managed code inside native applications for your personal projects https://github.com/Reloaded-Project/Reloaded-II
.NET Framework is long out of support and only gets security updates these days.
I have no idea how DirectX works, but I wonder if it would be a lot of work to support DX12, given it should be pretty similar to DX11?
