// dear imgui: Renderer Backend for DirectX12
|
||||
// This needs to be used along with a Platform Backend (e.g. Win32)
|
||||
|
||||
// Implemented features:
|
||||
// [X] Renderer: User texture binding. Use 'D3D12_GPU_DESCRIPTOR_HANDLE' as texture identifier. Read the FAQ about ImTextureID/ImTextureRef!
|
||||
// [X] Renderer: Large meshes support (64k+ vertices) even with 16-bit indices (ImGuiBackendFlags_RendererHasVtxOffset).
|
||||
// [X] Renderer: Texture updates support for dynamic font atlas (ImGuiBackendFlags_RendererHasTextures).
|
||||
// [X] Renderer: Expose selected render state for draw callbacks to use. Access in '(ImGui_ImplXXXX_RenderState*)GetPlatformIO().Renderer_RenderState'.
|
||||
// [X] Renderer: Multi-viewport support (multiple windows). Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
|
||||
|
||||
// The aim of imgui_impl_dx12.h/.cpp is to be usable in your engine without any modification.
|
||||
// IF YOU FEEL YOU NEED TO MAKE ANY CHANGE TO THIS CODE, please share them and your feedback at https://github.com/ocornut/imgui/
|
||||
|
||||
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
||||
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.

|

|

// Implemented features:

// [X] Platform: Clipboard support (for Win32 this is actually part of core dear imgui)
|
||||
// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen.
|
||||
// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy VK_* values are obsolete since 1.87 and not supported since 1.91.5]
|
||||
// [X] Platform: Gamepad support.
|

// [X] Platform: Mouse cursor shape and visibility (ImGuiBackendFlags_HasMouseCursors). Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
