// dear imgui: Renderer Backend for DirectX12
|
|
|
|
// This needs to be used along with a Platform Backend (e.g. Win32)
|

|
|
|
|
|
|
|
// Implemented features:
|
2019-10-16 17:23:15 +08:00
|
|
|
// [X] Renderer: User texture binding. Use 'D3D12_GPU_DESCRIPTOR_HANDLE' as ImTextureID. Read the FAQ about ImTextureID!
|
2019-10-19 00:03:56 +08:00
|
|
|
// [X] Renderer: Multi-viewport support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
|
2019-11-20 18:58:25 +08:00
|
|
|
// [X] Renderer: Support for large meshes (64k+ vertices) with 16-bit indices.

|
|
|
// Important: to compile on 32-bit systems, this backend requires code to be compiled with '#define ImTextureID ImU64'.
|
2020-09-09 02:02:28 +08:00
|
|
|
// This is because we need ImTextureID to carry a 64-bit value and by default ImTextureID is defined as void*.
|
2020-12-10 01:12:38 +08:00
|
|
|
// This define is set in the example .vcxproj file and need to be replicated in your app or by adding it to your imconfig.h file.

// 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.
