 SR is a lightweight software rendering library written in C.  It exposes the main algorithms, data structures, and math behind the standard real-time rendering model used in popular graphics api's like OpenGL and DirectX3D.  This project is entirely educational, and is free for anyone to use / adapt.  SR is tested with the [Unity Framework](http://www.throwtheswitch.org/unity) and the examples use SDL2 in order to display its output buffer.
