skoehler stole your dweet
u/warbino

ummmm someone stole your code............... his name is skoehler .
u/cantelope

@warbino, @thenize. this may be the last time you are reminded about the spirit of this platform. we do not dwell on "stealing" of code, as remixes are a provided function of the site. Your pattern of edge comments itself, since it continues, may be considered abuse. Unless you stop, there may be action.

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.
