Growing fitted textures

Abstract

In this paper, we address the problem of how to seamlessly and without repetition artifacts or visible projective distortion cover the surface of a polygonally-defined model with a texture pattern derived from an acquired 2D image such that the dominant orientation of the pattern will everywhere follow the surface shape in an aesthetically pleasing way. Specifically, we propose an efficient, automatic method for synthesizing, from a small sample swatch, patches of perceptually similar texture in which the pattern orientation may locally follow a specified vector field, such as the principal directions of curvature, at a per-pixel level, and in which the continuity of large and small scale features of the pattern is generally preserved across adjacent patches. We demonstrate the results of our method with a variety of texture swatches applied to standard graphics datasets.
