// 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 ImTextureID. Read the FAQ about ImTextureID!
|
||||
// [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'.
|
||||
// This is because we need ImTextureID to carry a 64-bit value and by default ImTextureID is defined as void*.
|
||||
// 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 copy and use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
||||
// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
|
||||
// Read online: https://github.com/ocornut/imgui/tree/master/docs
|
||||
|
||||
// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||

// 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 ImTextureID. Read the FAQ about ImTextureID!
|
||||
// [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'.
|
||||
// This is because we need ImTextureID to carry a 64-bit value and by default ImTextureID is defined as void*.
|
||||
// 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 copy and use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
||||
// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
