                 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.
