// 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: Large meshes support (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.
|
|
