Summary
This paper deals with the volume preserving smoothing of triangular isotropic meshes over three-dimensional open surfaces. The adopted approach is based on Laplacian smoothing combining in an alternating manner positive and negative weights in consecutive cycles of the smoothing. Since the aim is to improve the shape of individual elements of the mesh rather than to get rid of noise, the weights are derived in a very simple way using a "do-not-harm" concept. The paper also extends the application of the smoothing from closed surfaces to open surfaces and their combination. The performance and capabilities of the presented methodology are demonstrated on several examples.
