Abstract: This paper proposes an efficient mesh smoothing method. The method can smooth mesh fast, while preserving features. It smoothes the normal of every triangle in the mesh and ges the normal of every point in the mesh after normal smoothing, improves the moving direction of the vertices according to the distances between current vertex and adjacent vertices, and the angles between the normal of current vertex and of adjacent vertices, gets the weight of each vertex in the iteration using Gaussian. It provides a series of examples to demonstrate the effectiveness of the method presented with less iteration and volume shrinkage.

Key words: mesh smoothing, Gaussian kernel, feature preserving
