// ImGui Win32 + DirectX12 binding |
|
// In this binding, ImTextureID is used to store a 'D3D12_GPU_DESCRIPTOR_HANDLE' texture identifier. 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 use this binding you'll need to call 4 functions: ImGui_ImplXXXX_Init(), ImGui_ImplXXXX_NewFrame(), ImGui::Render() and ImGui_ImplXXXX_Shutdown(). |
|
// If you are new to ImGui, see examples/README.txt and documentation at the top of imgui.cpp. |
