Appearance of Low Poly Meshes
Objects that are said to be low poly often appear blocky (such as square heads) and lacking in detail (such as no individual fingers). Objects that are supposed to be circular or spherical are most obviously low poly as the number of triangles needed to make a curve appear smooth is high and polygons are restricted to straight edges. Low poly meshes do not necessarily look bad, for example a flat sheet of paper represented by one polygon looks extremely accurate.
Computer graphics techniques such as normal and bump mapping have been designed to make a low poly object appear to contain more polygons than it does. This is done by altering the shading of polygons to contain internal detail which is not in the mesh.

Famous quotes containing the words appearance of, appearance and/or meshes:
“February is a suitable month for dying. Everything around is dead, the trees black and frozen so that the appearance of green shoots two months hence seems preposterous, the ground hard and cold, the snow dirty, the winter hateful, hanging on too long.”
—Anna Quindlen (b. 1952)
“By nature servile, people attempt at first glance to find signs of good breeding in the appearance of those who occupy more exalted stations.”
—Anton Pavlovich Chekhov (18601904)
“The spider-mind acquires a faculty of memory, and, with it, a singular skill of analysis and synthesis, taking apart and putting together in different relations the meshes of its trap. Man had in the beginning no power of analysis or synthesis approaching that of the spider, or even of the honey-bee; but he had acute sensibility to the higher forces.”
—Henry Brooks Adams (18381918)
