contours

for some reason i always think i wrote these down somewhere i didn’t, so i write them here:

from 0 to 1, we may make a cheesy curve as x * x

instead of (1-x) * (1-x) to produce the inverse, we can write x * (2-x)

and as an interesting expansion of this form imo, we can produce an s-curve in this range,

x * x * (3 – 2x)

 

easy stuff, been a while :p
