OpenGL Fragment/Pixel Shaders (2020)| Color and Geometry

Have you ever wondered how color and gemoetric patterns get displayed by an OpenGL fragment shader? Why is graphics programming so mathy?

Well, we use functions to modify how color and geometry behave on-screen. The same algebraic functions you learned about in highschool.

I give you the basic rundown of how this gets achieved. Don't worry, the video isn't mathy.

It's a smooth introduction into what is going on... ...on a conceptual level.

Enjoy.
