A graphical API produced by Silicon Graphics that is platform independent, unlike Direct3D. It is also much easier to program 3D applications with, do to the absence of Microsoft Code.
OpenGL is a graphics API that was initially created by Silicon Graphics in 1992 for their 3D workstations. OpenGL is a specification this means the manufacture of your graphics driver has taken the liberty to write the code for OpenGL.
OpenGL is a state machine API, this is expressed through functions such as glBindBuffers(), glUseProgram().
OpenGL has been used in popular game engines such as Unity.
However, nowadays OpenGL has been deprecated on many systems in favor for Vulkan, a more verbose graphics API.
A geek-culture meme or catchphrase used to describe any task or situation that is notoriously difficult, complex, or prone to failure. It's a play on the acronym for the "Open Graphics Library," a computer graphics API infamous for its steep learning curve. The phrase "Open" followed by "Good Luck" is a wry acknowledgment that you are about to embark on a journey where success is far from guaranteed.
