// dear imgui: Renderer for DirectX12
|
|
// This needs to be used along with a Platform Binding (e.g. Win32)
|
|
|
|
// Implemented features:
|
|
// [X] Renderer: User texture binding. Use 'D3D12_GPU_DESCRIPTOR_HANDLE' as ImTextureID. Read the FAQ about ImTextureID!
|
|
// [X] Renderer: Multi-viewport support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
|
|
// [X] Renderer: Support for large meshes (64k+ vertices) with 16-bit indices.
|
|
// Missing features, issues:
|
|
// [ ] 64-bit only for now! (Because sizeof(ImTextureId) == sizeof(void*)). See github.com/ocornut/imgui/pull/301
|
|
|
|
// 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.
