// dear imgui: Renderer Backend for Metal // This needs to be used along with a Platform Backend (e.g. OSX) // Implemented features: // [X] Renderer: User texture binding. Use 'MTLTexture' as ImTextureID. Read the FAQ about ImTextureID! // [X] Renderer: Support for large meshes (64k+ vertices) with 16-bit indices. // 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 #include "imgui.h" // IMGUI_IMPL_API //----------------------------------------------------------------------------- // ObjC API //----------------------------------------------------------------------------- #ifdef __OBJC__ @class MTLRenderPassDescriptor; @protocol MTLDevice, MTLCommandBuffer, MTLRenderCommandEncoder; IMGUI_IMPL_API bool ImGui_ImplMetal_Init(id<MTLDevice> device); IMGUI_IMPL_API void ImGui_ImplMetal_Shutdown(); IMGUI_IMPL_API void ImGui_ImplMetal_NewFrame(MTLRenderPassDescriptor* renderPassDescriptor); IMGUI_IMPL_API void ImGui_ImplMetal_RenderDrawData(ImDrawData* drawData, id<MTLCommandBuffer> commandBuffer, id<MTLRenderCommandEncoder> commandEncoder); // Called by Init/NewFrame/Shutdown IMGUI_IMPL_API bool ImGui_ImplMetal_CreateFontsTexture(id<MTLDevice> device); IMGUI_IMPL_API void ImGui_ImplMetal_DestroyFontsTexture(); IMGUI_IMPL_API bool ImGui_ImplMetal_CreateDeviceObjects(id<MTLDevice> device); IMGUI_IMPL_API void ImGui_ImplMetal_DestroyDeviceObjects(); #endif //----------------------------------------------------------------------------- // C++ API //----------------------------------------------------------------------------- // Enable Metal C++ binding support with '#define IMGUI_IMPL_METAL_CPP' in your imconfig.h file // More info about using Metal from C++: https://developer.apple.com/metal/cpp/ #ifdef IMGUI_IMPL_METAL_CPP #include <Metal/Metal.hpp> #ifndef __OBJC__ IMGUI_IMPL_API bool ImGui_ImplMetal_Init(MTL::Device* device); IMGUI_IMPL_API void ImGui_ImplMetal_Shutdown(); IMGUI_IMPL_API void ImGui_ImplMetal_NewFrame(MTL::RenderPassDescriptor* renderPassDescriptor); IMGUI_IMPL_API void ImGui_ImplMetal_RenderDrawData(ImDrawData* draw_data, MTL::CommandBuffer* commandBuffer, MTL::RenderCommandEncoder* commandEncoder); // Called by Init/NewFrame/Shutdown IMGUI_IMPL_API bool ImGui_ImplMetal_CreateFontsTexture(MTL::Device* device); IMGUI_IMPL_API void ImGui_ImplMetal_DestroyFontsTexture(); IMGUI_IMPL_API bool ImGui_ImplMetal_CreateDeviceObjects(MTL::Device* device); IMGUI_IMPL_API void ImGui_ImplMetal_DestroyDeviceObjects(); #endif #endif
