The file contains not only vertex and face information but analytically calculated curvature, normals, and area. The format of the file is similar to the one listed except the vertex and face keywords are missing, each vertex has the information listed at the top of the file, and the faces are all triangular so the number of sides is not given.

The curvature data is in the following order:

vertID Pt Area, Normal, PrincipCrv1, PrincipCrv2, PrincipVec1, PrincipVec2

The first line of the file contains that descriptive bit. I believe the curvatures are sorted to have the larger value first.
