Go to the documentation of this file.

// dear imgui: Renderer for Metal
// This needs to be used along with a Platform Binding (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 copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
// If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp.
