Confronto tra tecniche per il Riconoscimento di geometrie assialsimmetriche in modelli tessellati

The estimation of axis of axial symmetric geometries, and of other surface differential properties is essential for many applications of geometric models defined by triangular meshes. In this work two methods for axis determination, described in literature, are analyzed and compared. For each method several variants have been carried out; these variants differ for the evaluation criteria of some factors, such as the normal estimation at a vertex of the tessellated model. The methods are compared also in the analysis of models that differ each other for size and regularity of the mesh.
