       USAGE

       DESCRIPTION

       _t_o_p__l_a_t_i_t_u_d_e    Estimated apex of subject's actual
                       (desired?) hair.

       _c_l_i_p-_l_a_t_i_t_u_d_e   The number of latitudes below _t_o_p-_l_a_t_i_t_u_d_e
                       to make void prior to applying the ttttoooouuuuppppeeeeeeee
                       function.
       TTTToooouuuuppppeeeeeeee provides a means of filling the void regions normally
       occurring near the top of the portrait sculpture subject's
       hair in such a way as to produce a reasonable facsimile of
       the surface contour one might expect.  In general this
       command is employed both to enhance the appearance of
       plotted profile views as well as to reduce the effort
       required to sculpt the top of busts following the machining
       process.

       This command requires only one argument and that is your
       estimate of the latitude at which the subject's hair
       intersects the cylindrical axis.  Along each longitude, from
       the first non-void data point to _t_o_p-_l_a_t_i_t_u_d_e, each radius
       is replaced by a value satisfying an expression defining a
       parabolic trajectory connecting these two end points.

       In some instances you may wish to first clip the data from a
       certain number of latitudes below your _t_o_p__l_a_t_i_t_u_d_e estimate
       if it appears that they might conflict with the ttttoooouuuuppppeeeeeeee
       interpolation function.  The effect of _c_l_i_p-_l_a_t_i_t_u_d_e is
       equivalent to invoking the iiiinnnnttttsssseeeetttt command in the latitude
       range extending from _t_o_p__l_a_t_i_t_u_d_e to _t_o_p-_l_a_t_i_t_u_d_e - _c_l_i_p-
       _l_a_t_i_t_u_d_e.

       CAVEATS

       You may find that a few stray data points high in the image
       may result in toupee producing anomalous profiles for some
       longitudes.  The selective implementation of intset or
       extset in conjunction with ltrange and lgrange may be
       necessary to remove the source of interference with toupee.
