vcurvature -- 3d curvature computations 

\fBDescription\fP
.RS 4
3d curvature computations\&. For each surface voxel, a curvature feature is computed\&. Surface voxels are defined by a threshold\&. The algorithm is based on discrete approximations to second-order derivatives and the Weingarten equations\&.
