Upcoming Video
Added 2023-05-04 10:30:49 +0000 UTCA few months ago I ran into the need to render some pixel art assets at arbitrary, sometimes non-integer upscaling ratios, and not always aligned to the device's native pixel grid, without suffering from the aliasing and jittering artifacts you would normally get with a nearest-neighbor sampler.
This is a subject which has been covered before by others, but I took it just a little further by generalizing it to work for arbitrary texture transforms, such as the kind you get when placing pixel art assets in 3D environments (like octopath traveler), or using pixel art textures on low-poly objects (like minecraft).
The video will briefly go through concepts ranging from texture sampling, box filtering, space transformations, and shaders programming.
There's still some work left to be done on the video, but I hope it will be ready soon. I took a try at making some pixel art myself for the video as the example subject:
coming soon(TM)
