anisotropic polygonal remeshing [alliez]

i just love this image. reminds me of those old-school how to cartoon books. in reality it is an important paper on principal curves as they relate to mesh.

skilled mesh designers tend to intuitively align edges with minimum and maximum curvatures in anisotripic areas, which can be seen in this image (alliez, cohen-steiner, levy and desbrun)
