5 - Algorithmic Drawing

• neat square wave function: y = ceil(sin(x+u_time)) + floor(sin(x+u_time));, I'd never considered it in that way before
• Golan Levin's shaping functions:
  • polynomial
  • exponential
  • elliptical
  • bezier + other
• Inigo Quilez has many resources, but here is one of shaping functions
  • each one is also available in the very cool graphtoy.com
    • sadly can't seem to link directly to functions because the unescaped parens mess up the markdown formatting. Maybe they could be escaped, but, irritating.
• lygia.xyz shader library
