Eh not really. Instagram filters are hard coded to work on people and mostly work by scanning for facial features and placing a 3d model/effects in relation to it. This actually generated an entirely new image based on everything in the original.

it’s incredible that this can be done in real time on a consumer GPU.

this is also stupid and completely useless

Not sure if it’s just what they want, it’s mostly that Minecraft’s spaghetti code had a lot of things hardcoded. Lately they’ve been changing a lot of things to be data-driven, and able to be changed by datapacks
