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.
