Use 'VkDescriptorSet' as ImTextureID. Read the FAQ about ImTextureID! See https://github.com/ocornut/imgui/pull/914 for discussions. - -// Important: on 32-bit systems, user texture binding is only supported if your imconfig file has '#define ImTextureID ImU64'. -// This is because we need ImTextureID to carry a 64-bit value and by default ImTextureID is defined as void*. -// To build this on 32-bit systems and support texture changes: -// - [Solution 1] IDE/msbuild: in "Properties/C++/Preprocessor Definitions" add 'ImTextureID=ImU64' (this is what we do in our .vcxproj files) -// - [Solution 2] IDE/msbuild: in "Properties/C++/Preprocessor Definitions" add 'IMGUI_USER_CONFIG="my_imgui_config.h"' and inside 'my_imgui_config.h' add '#define ImTextureID ImU64' and as many other options as you like. -// - [Solution 3] IDE/msbuild: edit imconfig.h and add '#define ImTextureID ImU64' (prefer solution 2 to create your own config file!) -// - [Solution 4] command-line: add '/D ImTextureID=ImU64' to your cl.exe command-line (this is what we do in our batch files) - -// 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. -// Read comments in imgui_impl_vulkan.h. - -// CHANGELOG -// (minor and older changes stripped away, please see git history for details) -// 2021-10-15: Vulkan: Call vkCmdSetScissor() at the end of render a full-viewport to reduce likehood of issues with people using VK_DYNAMIC_STATE_SCISSOR in their app without calling vkCmdSetScissor() explicitly every frame. -// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX). -// 2021-03-22: Vulkan: Fix mapped memory validation error when buffer sizes are not multiple of VkPhysicalDeviceLimits::nonCoherentAtomSize. -// 2021-02-18: Vulkan: Change blending equation to preserve alpha in output buffer. -// 2021-01-27: Vulkan: Added support for custom function load and IMGUI_IMPL_VULKAN_NO_PROTOTYPES by using ImGui_ImplVulkan_LoadFunctions(). -// 2020-11-11: Vulkan: Added support for specifying which subpass to reference during VkPipeline creation. -// 2020-09-07: Vulkan: Added VkPipeline parameter to ImGui_ImplVulkan_RenderDrawData (default to one passed to ImGui_ImplVulkan_Init). -// 2020-05-04: Vulkan: Fixed crash if initial frame has no vertices. -// 2020-04-26: Vulkan: Fixed edge case where render callbacks wouldn't be called if the ImDrawData didn't have vertices. -// 2019-08-01: Vulkan: Added support for specifying multisample count. Set ImGui_ImplVulkan_InitInfo::MSAASamples to one of the VkSampleCountFlagBits values to use, default is non-multisampled as before. -// 2019-05-29: Vulkan: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag. -// 2019-04-30: Vulkan: Added support for special ImDrawCallback_ResetRenderState callback to reset render state. -// 2019-04-04: *BREAKING CHANGE*: Vulkan: Added ImageCount/MinImageCount fields in ImGui_ImplVulkan_InitInfo, required for initialization (was previously a hard #define IMGUI_VK_QUEUED_FRAMES 2). Added ImGui_ImplVulkan_SetMinImageCount(). -// 2019-04-04: Vulkan: Added VkInstance argument to ImGui_ImplVulkanH_CreateWindow() optional helper. -// 2019-04-04: Vulkan: Avoid passing negative coordinates to vkCmdSetScissor, which debug validation layers do not like. -// 2019-04-01: Vulkan: Support for 32-bit index buffer (#define ImDrawIdx unsigned int). -// 2019-02-16: Vulkan: Viewport and clipping rectangles correctly using draw_data->FramebufferScale to allow retina display. -// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window. -// 2018-08-25: Vulkan: Fixed mishandled VkSurfaceCapabilitiesKHR::maxImageCount=0 case. -// 2018-06-22: Inverted the parameters to ImGui_ImplVulkan_RenderDrawData() to be consistent with other backends. -// 2018-06-08: Misc: Extracted imgui_impl_vulkan.cpp/.h away from the old combined GLFW+Vulkan example. -// 2018-06-08: Vulkan: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle. -// 2018-03-03: Vulkan: Various refactor, created a couple of ImGui_ImplVulkanH_XXX helper that the example can use and that viewport support will use. -// 2018-03-01: Vulkan: Renamed ImGui_ImplVulkan_Init_Info to ImGui_ImplVulkan_InitInfo and fields to match more closely Vulkan terminology. -// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback, ImGui_ImplVulkan_Render() calls ImGui_ImplVulkan_RenderDrawData() itself. -// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves. -// 2017-05-15: Vulkan: Fix scissor offset being negative. Fix new Vulkan validation warnings. Set required depth member for buffer image copy. -// 2016-11-13: Vulkan: Fix validation layer warnings and errors and redeclare gl_PerVertex. -// 2016-10-18: Vulkan: Add location decorators & change to use structs as in/out in glsl, update embedded spv (produced with glslangValidator -x).
