6.1.2.2 Optimizing Texture Coordinate Assignment

Sloan, Weinstein, and Brederson [90] have explored optimizing the assignment of texture coordinates based on an ``importance map'' that can encode both intrinsic texture properties as well as user-guided highlights. Such importance driven texture coordinate optimization techniques highlight the fact that textured detail is very likely not uniformly distributed for a particular texture image and a particular texture coordinate assignment. Warping the texture image and changing the texture coordinate assignment provides opportunities for improving texture appearance without increasing the texture size.
