(LaTeX) Abstract:

Triangle meshes are a facile and effective representation for
many kinds of surfaces. In order to rate the quality of a surface, the
calculation of geometric curvatures as there are defined for smooth
surfaces is useful and necessary for a variety of applications. We
investigate an approach to locally approximate the first and second
fundamental forms at every (inner) vertex of a triangle mesh. We use
locally isometric divided difference operators, where we compare two
variants of parameterizations (tangent plane and exponential map) by
testing on elementary analytic surfaces.

We further describe a technique for visualizing the resulting curvature
data. A simple median filter is used to effectively filter noise from
the input data. According to application dependent requirements a global or a per-vertex local
color coding can be provided. The user may interactively modify the color
transfer function, enabling him or her to visually evaluate the quality of triangulated surfaces.
