Efficient Smoothness-Preserving Fusion Modelling Method for Mesh Models

The essential process of preserving the smoothness of stitched meshes in mesh model fusion is challenging. This paper proposes an efficient mesh model fusion method to preserve the smoothness of the stitched surface along two stitching meshes. We first cut parts of the stitched meshes from source mesh models and then extract their boundary contours. Subsequently, the boundary contours are aligned manually and projected onto parallel planes for contour vertex triangulation. Triangular meshes obtained from the stitched meshes by loop subdivision are interpolated using a compactly supported radial basis function to smooth the stitched surfaces. The experimental results on public graph models demonstrate the effectiveness and efficiency of our method in mesh model fusion and smoothness.
