3D model partial-resizing via normal and texture map combination

Resizing of 3D model is necessary for computer graphics animation and application such as games and movies. In general, when users deform a target model, they built on a bounding box or a closed polygon mesh (cage) to enclose a target model. Then, the resizing is done by deforming the cage with target model. However, these approaches are not good for detailed adjustment of 3D shape because they do not preserve local information. In contrast, based on a local information (e.g., edge set and weight map), Sorkine et al. [Sorkine and Alexa 2007; Sorkine et al. 2004] can generate smooth and conformal deformation results with only a few control points. While these approaches are useful for some situations, the results depend on resolution and topology of the target model. In addition, these approaches do not consider texture (UV) information.
