imgui/examples/imgui_impl_dx11.h

// ImGui Renderer for: DirectX11
// This needs to be used along with a Platform Binding (e.g. Win32)

// Implemented features:
//  [X] Renderer: User texture binding. Use 'ID3D11ShaderResourceView*' as ImTextureID. Read the FAQ about ImTextureID in imgui.cpp.

// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
// If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp.
