// COMPILE-TIME OPTIONS FOR DEAR IMGUI
|
||||
// Runtime options (clipboard callbacks, enabling various features, etc.) can generally be set via the ImGuiIO structure.
|
||||
// You can use ImGui::SetAllocatorFunctions() before calling ImGui::CreateContext() to rewire memory allocation functions.
|
||||
//-----------------------------------------------------------------------------
|
||||
// A) You may edit imconfig.h (and not overwrite it when updating Dear ImGui, or maintain a patch/rebased branch with your modifications to it)
|
||||
// B) or '#define IMGUI_USER_CONFIG "my_imgui_config.h"' in your project and then add directives in your own file without touching this template.
|
||||
//-----------------------------------------------------------------------------
|
||||
// You need to make sure that configuration settings are defined consistently _everywhere_ Dear ImGui is used, which include the imgui*.cpp
|
||||
// files but also _any_ of your code that uses Dear ImGui. This is because some compile-time options have an affect on data structures.
|
||||
// Defining those options in imconfig.h will ensure every compilation unit gets to see the same data structure layouts.
|
||||
// Call IMGUI_CHECKVERSION() from your .cpp files to verify that the data structures your files are using are matching the ones imgui.cpp is using.

||||

// dear imgui: Renderer Backend for DirectX11
|
||||
// This needs to be used along with a Platform Backend (e.g. Win32)
|
||||
|
||||
// Implemented features:
|
||||
// [X] Renderer: User texture binding. Use 'ID3D11ShaderResourceView*' as ImTextureID. Read the FAQ about ImTextureID!
|
||||
// [X] Renderer: Support for large meshes (64k+ vertices) with 16-bit indices.
|
||||
|
||||
// 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)
|
||||
// 2021-02-18: DirectX11: Change blending equation to preserve alpha in output buffer.
|
||||
// 2019-08-01: DirectX11: Fixed code querying the Geometry Shader state (would generally error with Debug layer enabled).
|
||||
// 2019-07-21: DirectX11: Backup, clear and restore Geometry Shader is any is bound when calling ImGui_ImplDX10_RenderDrawData. Clearing Hull/Domain/Compute shaders without backup/restore.
|
||||
// 2019-05-29: DirectX11: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
||||
// 2019-04-30: DirectX11: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
||||
// 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.
|
||||
// 2018-08-01: DirectX11: Querying for IDXGIFactory instead of IDXGIFactory1 to increase compatibility.
|
||||
// 2018-07-13: DirectX11: Fixed unreleased resources in Init and Shutdown functions.
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_dx11.cpp/.h away from the old combined DX11+Win32 example.
|
||||
// 2018-06-08: DirectX11: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
|
||||
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX11_RenderDrawData() in the .h file so you can call it yourself.
|
||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
|
||||
// 2016-05-07: DirectX11: Disabling depth-write.

// This needs to be used along with a Renderer (e.g. DirectX11, OpenGL3, Vulkan..)
|

|

// Implemented features:
|

// [X] Platform: Clipboard support (for Win32 this is actually part of core dear imgui)
|

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

// [X] Platform: Keyboard arrays indexed using VK_* Virtual Key Codes, e.g. ImGui::IsKeyPressed(VK_SPACE).
|

// [X] Platform: Gamepad support. Enabled with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
|

// You can copy and use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
