// 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.
|
|
|
|
// 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/
|
|
|
|
// 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.
|
|
// Learn about Dear ImGui:
|
|
// - FAQ https://dearimgui.com/faq
|
|
// - Getting Started https://dearimgui.com/getting-started
|
|
// - Documentation https://dearimgui.com/docs (same as your local docs/ folder).
|
|
// - Introduction, links and more at the top of imgui.cpp
|
|
|
|
// Important note to the reader who wish to integrate imgui_impl_vulkan.cpp/.h in their own engine/app.
|
|
// - Common ImGui_ImplThin3d_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_ImplThin3dH_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.
|
|
// Read comments in imgui_impl_vulkan.h.
