George Wolberg 写的《Digital Image Warping》[0] 这本书非常详尽地讲解了这些技巧，以及重采样滤波器的选择。如今的世界已经大不相同了，双线性纹理采样已经内置进了 GPU 硬件，而且……
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…
……IT？回答可以包含领域描述（软件开发 - gis/图形学/无线电通信）、问题描述（插值）、关键数学能力（卷积、冲激响应）、基础文献（wolberg - digital image warping；pharr & humphreys - physically based rendering）、参考/知名（但最好轻量）的实现（anti-grain geometry），等等。
…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.
