OpenGL Fragment/Pixel Shaders (2020)| You Need (GLSL) Step and Smoothstep in Your Life

In this video I go over a pair of vital GLSL functions used in fragment(pixel) shader graphics programming: step and smoothstep.

I take a look at the syntax for the two and then I use a line drawing function to show you how smoothstep can produce a line.

At the end of the video I briefly introduce you to what "shaping" functions are and how we can use them to manipulate what gets drawn on our OpenGL canvas.
