Digital image warping

What Hacker News says

1. raphlinusDec 2017
   The book "Digital Image Warping" by George Wolberg[0] goes into these tricks in great detail, as well as choices for the resampling filter.

   The world is very different today, bilinear texture sampling is built into GPU hardware and is lightning fast. The idea that a sequence of skews might be more efficient is a curious relic of when CPU was considered a reasonable place to do image transformation.

   What are the most mathematically demanding areas in IT? Answers can contain field description (SW devel - gis/graphics/radiocommunication), problem description (interpolation), key math abilities (convolution, impulse response), basic literature (wolberg - digital image warping; pharr & humphreys - physically based rendering), reference/notable (but preferably lightweight) implementations (anti-grain geometry), and so on.
