Abstract
Surface simplification aims to reduce the complexity of a 3D model while maintaining a good approximation to the original model. In this work, we propose a novel combination of geometry images and content-aware image resizing to achieve efficient surface simplification. There are two main advantages to simplify surface based on geometry images. First, it is relatively simple to simplify the surface in the parameterized 2D space because the features of a 3D surface can be easily represented by the gradient energy. Second, the regularity and features on 3D surface can also be preserved without additional effort. The proposed retargeting algorithm performs well both on real images and 3D surface simplification.
