SYNOPSIS

Detailed Description

       vcurvature -- 3d curvature computations

       Description.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.
