sofia ☮️🏴i'd really like to see edge-directed interpolation used on the textures of PS1/Quake-era
games. i think it would probably fit the low-poly aestetic quite well.
Wikipedia doesn't have a lot on those algorithms, but that's how i discovered them:
https://en.wikipedia.org/wiki/Image_scaling#Edge-directed_interpolation
https://en.wikipedia.org/wiki/Directional_Cubic_Convolution_Interpolation
the algorithm doesn't seem super complicated, but there don't seem many implementations out there…
