// 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 Vulkan
|
||||||
|
// This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)
|
||||||
|
|
||||||
|
// Implemented features:
|
||||||
|
// [!] Renderer: User texture binding. Use 'VkDescriptorSet' as ImTextureID. Read the FAQ about ImTextureID! See https://github.com/ocornut/imgui/pull/914 for discussions.
|
||||||
|
// [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.
|
||||||
|
|
||||||
|
// Important: on 32-bit systems, user texture binding is only supported if your imconfig file has '#define ImTextureID ImU64'.
|
||||||
|
// See imgui_impl_vulkan.cpp file for details.
|
||||||
|
|
||||||
|
// 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.
|
||||||
|
// 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
|
||||||
|
|
||||||
|
// The aim of imgui_impl_vulkan.h/.cpp is to be usable in your engine without any modification.
|
||||||
|
// IF YOU FEEL YOU NEED TO MAKE ANY CHANGE TO THIS CODE, please share them and your feedback at https://github.com/ocornut/imgui/
|
||||||
|
|
||||||
|
// Important note to the reader who wish to integrate imgui_impl_vulkan.cpp/.h in their own engine/app.
|
||||||
|
// - Common ImGui_ImplVulkan_XXX functions and structures are used to interface with imgui_impl_vulkan.cpp/.h.
|
||||||
|
// You will use those if you want to use this rendering backend in your engine/app.
|
||||||
|
// - Helper ImGui_ImplVulkanH_XXX functions and structures are only used by this example (main.cpp) and by
|
||||||
|
// the backend itself (imgui_impl_vulkan.cpp), but should PROBABLY NOT be used by your own engine/app code.

|

|
// Sean Barrett 2014
|
||||||
|
//
|
||||||
|
// Useful for e.g. packing rectangular textures into an atlas.
|
||||||
|
// Does not do rotation.
|

// Before #including,

//

|
// #define STB_RECT_PACK_IMPLEMENTATION
|
||||||
|
//
|
||||||
|
// in the file that you want to have the implementation.
|
||||||
|
//
|
||||||
|
// Not necessarily the awesomest packing method, but better than
|
||||||
|
// the totally naive one in stb_truetype (which is primarily what
|
||||||
|
// this is meant to replace).
|
||||||
|
//
|
||||||
|
// Has only had a few tests run, may have issues.
|
||||||
|
//
|
||||||
|
// More docs to come.
|
||||||
|
//
|
||||||
|
// No memory allocations; uses qsort() and assert() from stdlib.
|
||||||
|
// Can override those by defining STBRP_SORT and STBRP_ASSERT.
|
||||||
|
//
|
||||||
|
// This library currently uses the Skyline Bottom-Left algorithm.
|
||||||
|
//
|
||||||
|
// Please note: better rectangle packers are welcome! Please
|
||||||
|
// implement them to the same API, but with a different init
