// 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)
|
||||
// 2021-01-11: DirectX12: Improve Windows 7 compatibility (for D3D12On7) by loading d3d12.dll dynamically.
|
||||
// 2020-09-16: DirectX12: Avoid rendering calls with zero-sized scissor rectangle since it generates a validation layer warning.
|
||||
// 2020-09-08: DirectX12: Clarified support for building on 32-bit systems by redefining ImTextureID.
|
||||
// 2019-10-18: DirectX12: *BREAKING CHANGE* Added extra ID3D12DescriptorHeap parameter to ImGui_ImplDX12_Init() function.
|
||||
// 2019-05-29: DirectX12: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
||||
// 2019-04-30: DirectX12: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
||||
// 2019-03-29: Misc: Various minor tidying up.
|
||||
// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
|
||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
||||
// 2018-06-12: DirectX12: Moved the ID3D12GraphicsCommandList* parameter from NewFrame() to RenderDrawData().
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_dx12.cpp/.h away from the old combined DX12+Win32 example.
|
||||
// 2018-06-08: DirectX12: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle (to ease support for future multi-viewport).
|
||||
// 2018-02-22: Merged into master with all Win32 code synchronized to other examples.

// 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.
