TY - CONF T1 - A geometric approach to curvature estimation on triangulated 3D shapes T2 - Int. Conf. on Computer Graphics Theory and Applications (GRAPP) Y1 - 2010 A1 - Mesmoudi,M. M. A1 - De Floriani, Leila A1 - Magillo,P. AB - We present a geometric approach to define discrete normal, principal, Gaussian and mean curvatures, thatwe call Ccurvature. Our approach is based on the notion of concentrated curvature of a polygonal line and a simulation of rotation of the normal plane of the surface at a point. The advantages of our approach is its simplicity and its natural meaning. A comparison with widely-used discrete methods is presented. JA - Int.
