OpenGL is a cross-platform, industry standard graphics programming API for 3D graphics.

• It handled the hardware-accelerated rendering of 2D and 3D graphics.

OpenGL is not exactly a library because each vendor has to implement the specification to produce an OpenGL library.

• Therefore, on Linux-based distributions, the libGL.so library file will be different for each vendor.
