[ compact version ] | [ modular version ]

Remember the old days when you were able to simply draw a few primitives with GL_POINTS, GL_LINES or GL_QUADS within a pair of good old begin() end(). Well I'm providing a C++ class which will enable you to do this again under OpenGL 3.1 or higher.

# C code for 4x4 matrix inversion

Just leaving some code here to invert either column or row major 4x4 matrices.
