gleScrew(3GLE)                        GLE                       gleScrew(3GLE)

NAME
       gleScrew - Draws screw-type shapes.

SYNTAX

       void gleScrew (int ncp,
                      gleDouble contour[][2],
                      gleDouble cont_normal[][2],
                      gleDouble up[3],
                   gleDouble startz,
                   gleDouble endz,
                   gleDouble twist);

ARGUMENTS
       ncp       number of contour points

       contour   2D contour

       cont_normal
                 2D contour normals

       up        up vector for contour

       startx    start of segment

       endz      end of segment

       twist     number of rotations

DESCRIPTION
       Draws screw-type shapes. Takes a contour, and extrudes it along the z-
       axis, from a start z value of startz to an end z-value of endz.  During
       the extrusion, it will spin the contour along the contour origin by
       twist degrees.
