Best Fit Decreasing for Fully Automatic Compact Texture Atlas Generation

Texture atlas is widely used in many applications such as texture mapping, 3D Paint and illumination map texture synthesis etc. Several methods have been proposed for generating texture atlas, but most of them are not compact enough for some applications or require too much manual intervention. This paper presents a fully automatic BFD approach to generate compact texture atlas for triangular mesh models. Our main contribution is making some modifications to a piecewise mesh parameterization method to control the shape of charts by introducing a new local criterion, and developing a novel rectangle-packing algorithm.
