    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

Bezier Sunset Gradient

u/cantelope

"bezier" tho? 🤔
u/andrea270872

Perhaps the function w is based on a Bezier curve between 4 points?
u/andrea270872

(like they say here... https://javascript.info/bezier-curve )?
u/LimeLaser

Yeah, the w function should be a cubic Bezier evaluation, but I had to cut out the a*v**3 term to fit the character limit.
