       point_array
                 polyline vertices

DESCRIPTION

       Draw polycylinder, specified as a polyline.

       Note  that  neither  the  very  first  segment,  nor  the very last segment are drawn. The first and last
       segments serve only to define the angle of the join at the very ends of the polyline. Thus, to  draw  one
       segment, three must be specified. To draw two segments, four must be specified, etc.

       The  color array may be NULL. If NULL, the current color is used. If not NULL, the glColor3f() routine is
       used to set the color; therefore, specifying the glColorMaterial() subroutine before this  primitive  can
       be used to set diffuse, specular, ambient, etc. colors.

       By default, the cross-section of the cylinder is drawn as a 20-sided polygon.  This number can be changed
       using the gleSetNumSides() routine.
