[Jaysmito101]

CGL (C Graphics Library) is a multipurpose library mainly for recreational coding / demo scenes / prototyping / small games / experimentation. This has got lots and lots of utilities ranging from procedural noise api, triangulation algorithm, neural networks, path finding, data structures, logger, markov chains, high-level opengl wrapper, openal wrapper, collision detection, post processing algorithms, math library (vectors, matrices, quaternions, etc), etc. It has also got a huge collection of examples to learn the API.
