OpenGL Fragment Shaders - Drawing Circles Using Distance Fields
What are Distance Fields? https://lbry.tv/@an_object_is_a:7/compressed-opengl-frag-shader-distance-fields:8
OpenGL step() and smoothstep(): https://lbry.tv/@an_object_is_a:7/opengl_fragment_shaders_step_and_smoothstep:0

I'm going to show you how to draw circles using distance fields in a fragment shader.
We'll take a look at three different algorithms that all produce the same distance field.
We'll then use glsl smoothstep() to create a solid circle.
Finally we'll quickly create a function that draws circles for us.
