Abstract

The surface curvature of the polygonal model represents a local shape feature of polygonal surface around one surface point. It has been used to analyze the shape of mesh model. In this paper, we present a novel approximation method of multi-scale surface curvature based on mesh simplification, which computes the Gaussian-weighted average of the mean curvature in different sized neighbor regions at a point while changing the resolution of the polygonal mesh. The proposed method was tested on different polygonal models and the experimental results showed that the overall shape features of the polygonal models were represented more clearly by our method.
