Abstract

Texture unwrapping is a nearly ubiquitous step in texture mapping, and serves two important purposes: (1) it indicates where to sample texture across each face and (2) it allows artistic freedom to "trade" texels from low importance areas to high importance areas. Unfortunately, texture unwrapping is time-consuming and automated tools generally produce inferior results to those of a skilled artist. Additionally, even the best unwraps suffer from seams, which cause lighting discontinuities at best and surface discontinuities at worst.
