About

metal-cpp is a low overhead and header only C++ interface for Metal that helps developers add Metal functionality to graphics applications that are written in C++ (such as game engines). metal-cpp removes the need to create a shim and allows developers to call Metal functions directly from anywhere in their existing C++ code.

Highlights

• Drop in C++ alternative interface to the Metal Objective-C headers.
• Direct mapping of all Metal Objective-C classes, constants and enums to C++ in the MTL C++ namespace.
• No measurable overhead compared to calling Metal Objective-C headers, due to inlining of C++ function calls.
