In mapping textures onto 3D models, it is essential to eliminate all seams and avoid excessive distortions. To achieve these goals, texture tiling provides an alternative approach for texturing surfaces. In this paper, a texture tiling approach that combines polycube- maps and Wang tiles for 3D models is proposed. The polycube of a 3D model is first constructed automatically and a tiling mechanism is then used to fill the tiles on the polycube. Finally, rectangular cells which are transformed from the polycube are generated and textures are mapped onto the 3D model. The results show that the proposed approach leads to seamless texture mapping on 3D models.
