What is OpenGL?
OpenGL is a cross-platform graphics API which is used as an interface to talk to the
graphics card. The most important feature of any graphics API is its ability to render ob-
jects on the screen. While OpenGL certainly does that, it has many other useful features.
However, since it has been around for years, and GPU technology has changed drastically,
not all features of the new versions of OpenGL are supported on all graphics cards.
