| Abstract / Description: | We introduce a new technique for estimating the curvature tensor of a
triangular mesh. The input of the algorithm is only a single triangle equipped
with its (exact or estimated) vertex normals. This way we get a smooth function
of the curvature tensor inside each triangle of the mesh. We show that the
error of the new method is comparable with the error of a cubic fitting
approach if the incorporated normals are estimated. If the exact normals of the
underlying surface are available at the vertices, the error drops signifi-
cantly. We demonstrate the applicability of the new estimation at a rather
complex data set. |
