OGLA : OpenGL Abstraction is a reference renderer implemented in C++.

The objective of this project is to abstract renderer functionality to serve as a foundation for simple 2D/3D real-time applications.

The design principle applied was to identify rendering engine concepts, and ecapsulate these in a simple and inteligible abstraction to be easily readable, understandable, learnable, and hackable.
