SpacePrincessAda / m3

Playground for Metal shading language in Objective-C and C.

Overview

This is a testbed for learning the Metal API and for developing a MacOS platform layer from scratch for a game written in C. It's designed to compile from the command line, with Xcode only used for debugging.

Currently the project has no third-party dependencies and will build on MacOS if the Xcode command line tools are installed.
