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.
If one wants to learn 3D programming, they should learn OpenGL.

Words you can keep
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.

tldr; OpenGL shows cool ass graphics
This renderer has a OpenGL rendering backend.
OpenGL by xff December 8, 2021
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.
I just saw the final exam study guide. Looks like it's "OpenGL" from here on out.

Back when I lived in upstate new york 

A meaningless, unimpressive, self-serving introduction. An indicator that the story about to be shared will be pointless and dumb.
Back when I lived in upstate new york, I also had to park on the street - on two occasions, we got enough snow, mixed with just the right plowing, that my car was lifted off the ground from so much snow being jammed underneath it.

Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.

Me: Woah! TLDU!
